MICHAEL M PIA TZMA/l A TTORNE'Y REVENUE CONTROL SYSTEM FOR TOLL ROADS This invention relates to revenue control systems and more specifically to a toll collecting system for use with either a closed loop system or barrier type system whereby revenue reconciliation is automatically accomplished.

BACKGROUND OF THE'INVENTION This system comprises various control means, which,

compiling the information available on millions of cancelled or receiptedtickets. Even with the barrier type systems, reconciliation generally requires constant monitoring'by supervisory personnel.

Closed loop systems in use today require pre -printed punch cards which are distributed to each vehicle enteringthe toll road. The pre-printed punch cards contain information relating to the entry point, generally by interchange number; and thetime of entry. The preprintedcards are classified by the type of vehicles using the toll road, generally by the number of axles which the vehicle contains. A distributor at the entry lane selects the proper pre-printed card and presents it to the vehicle driver. At the point of exit, a collector retrieves the punch card and reads the fee either directly from the pre-printed card, or from a table lookup.

The systems presentlyin use require the cumbersome task of distribution and collection of the preprinted cards. Furthermore, although there is generally an automatic axle counter provided at points of entry and points of exit, there is little, if any, accurate reconciliation between the total axle count and the fees collected at the interchanges. As a result of this lack of reconciliation, toll collectors acting in collusion with the vehicle driver can select a card for a lesser'number of axles then'the vehicle actually has. To check on the entrance toll collector, it would be necessary to take all the tickets for a fixed period of time from each exit and manually sort them for a given entrance and a given toll collectors tour of duty. A comparison could then be made between the axle count determined by the treadle counter at the selected entrance, and the axle count by totaling the punch cards.

.A limited reconciliation is made in present systems at each exit point since tickets which are collected by the cashier are forwarded to a central data processing center where they are tabulated to determine the amount of money the toll collector is responsible for and the total number of axles that have passed through his lane. However, since certain routine maintenance vehicles are given non-revenue tickets at an entrance and terminate at a maintenance building, this ticket may be passed to and substituted by an unscrupulous toll collector for the ticket of a vehicle that has paid the toll, thereby having the axle count on the treadle match the ticket axle count and the money collected being in the excess of that required. The excess funds are generally not turned in. At the present time, an audit of the funds for which the toll collector is responsible would take a day or more, with the problem of scanning every ticket by machinery and evaluating the cash value of these tickets for the distance traveled.

In the barrier type system, no tickets are issued but instead a fixed fee is paid at eachbarrier terminal. However, the schedule of fees depends upon the type of vehicle passing the barrier terminal. An unscrupulous collector could record a fee for a smaller type of vehicle while actually collecting a greater amount. Also many non-revenue vehicles could be registered at the terminal while the collector could personally retain the monies collected.

' BRIEF DESCRIPTION OF THE INVENTION Briefly, this invention describes a system having a number of terminals each in communication with a central computer. In the barrier type configuration the terminals contain a keyboard on which to register the fee to be collected and a display on which the amount can be seen by the driver. A vehicle detector counts the number of axles on the vehicle and determines the type of vehicle passing the barrier terminal. The information from the detector and the keyboard is sent to the computer for corroboration.

In the closed loop type configuration there are separate entry lanes and exit lanes, each of which is in communication with a central computer. Tickets are individually perforated or printed at each entry lane bearing the classification of vehicle type or axle number, the interchange number, the entry lane number, the identification number of the collector, the time and day of entry and a consecutive serial number. This information is simultaneously transmitted to a computer. At each exit lane there is provided a ticket reader which automatically reads the ticket retrieved from the vehicle driverand automatically displays the fee on a display device.

Each terminal is opened by a collector inserting a card bearing his individual identification number. At the opening of a terminal, the computer records the time and dayof opening, the interchange number, the lane number and tabulates the transactions previously completed prior to the present opening of the terminal. At a close of a tour of duty, the identification card is similarly entered into a card reader and the computer automatically closes the terminal recording information similar to that at the time of the opening. Should a collector neglect to close a lane, a new collector subsequently opening his tour of duty would automatically close out the previous tour before the opening procedure is initiated. Non-revenue cards can be recognized at the terminals and automatically verified by the computer. A receipt, when requested, is automatically printed for the availability of the vehicle driver.

It is, therefore, an object of this invention to provide an improved computer controlled, revenue control system for toll roads.

Another object is to provide a revenue control system for vehicle toll roads having a plurality of terminals each in communication with a central computer providing revenue reconciliation with vehicle type.

A further object is to provide a revenue control system for vehicle toll roads which can be used with either a barrier type configuration or a closed loop type configuration.

A further object of this invention is to eliminate problems of maintenance and audit control, simplify handling of tickets and reduce ticket data processing at a central office on toll road revenue systems.

A still further object of this invention is to provide a system which improves the supervision of toll collectors at toll plazas in revenue control systems.

Yet another object of this invention is to provide an automatic record of the transactions at points of entry and exit in a closed loop revenue control system which can be automatically transmitted to a central office by radio or wire.

A further object of this invention is to provide a closed loop toll revenue system wherein computer cards are automatically punched at each point of entry.

Yet another object of this invention is to provide a toll revenue system which reconciles the number of vehicles using the toll roads with the total fees collected.

Yet another object of this invention is to provide a toll revenue system which can be used by non-revenue paying vehicles or in conjunction with a credit card system.

A still further object of this invention is to provide a toll revenue system which will provide reliable statistical information on revenues collected at each exit which can then be tabulated and reconciled with the number and type of vehicles using the exits and correlated to their point of entry, without further processing ofthe tickets.

Yet another object of this invention is to provide an improved revenue control system of the barrier type which can be used with either automatic toll lanes or with collectors.

These and other objects of this invention will become more apparent from the following description of embodiments of this invention taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE INVENTION Referring now to FIG. 1 there is shown the system of this invention used in a closed loop type configuration wherein an entry validator is placed at the entry lane. The validator 10 is a unit containing a keyboard 11, a card reader 12, a ticket punch 13 and a storage drawer for unpunched tickets 14. Electrical connections are made to the unit 10 through the connector terminals on connector board 15. In a locked electrical compartment 15A tickets which are punched are ejected at 16. A lane signal 17 having red light 18 and green light 19 is electrically connected through line 20 to the connector board 15. A vehicle detection system 21 containing single or multi contact treadle type axle counters or electronic vehicle detection device is electrically connected by line 22 to the connector board 15. The validator unit 10 is electrically connected by means of line 23 to a central computer unit 24 contained in a room generally placed at the maintenance office at the plaza terminal. The computer unit 24 feeds an output peripheral unit 25 typically shown as a punch tape unit.

The exit lane has an exit validator 26 which is comprised of a ticket reader 27, a fee display device 28, a card reader 29, a receipt printer 30 and a cash drawer 31. Electrical connections are made to the exit validator 26 by means of connector board 32 in a locked electrical compartment 32A. Lane signal 33 comprising red light 34 and green light 35 are electrically connected by means of line 36 to the exit validator terminal connector board 32. A separate fee display unit 37 is electrically connected through line 38 to the terminal connector board 32. An exit vehicle detector system 39 containing detecting and counting means similar to that of entry detector system 21, is shown at 39 and electrically connected through line 40 to the terminal connector board 32. The exit validator 26 is electrically connected by means of line 41 to the computer unit 24 contained at the exit terminal maintenance office.

The operation of the system shown in FIG. 1 will now be described:

Initially a lane is closed and the lane signal 17 indicates the closed lane by means of the red signal light 18. Upon the beginning ofa tour of duty by a collector, the collector inserts his identification card bearing his identification number into the card reader 12. The identification number contains a predetermined number of digits. In this embodiment, four digits were used for the collector identification number. Upon insertion of the identification card into the card reader 12, the computer unit 24 records the interchange and lane designation numbers, the collector identification number, the time and day of the opening of the tour of duty and the traffic direction. A signal is sent to the computer programmer to change the lane signal identification to green light 19 indicating the lane is now open. The computer also sends a signal back to the card reader to eject the identification card. The computer also records the totals of the prior transaction count. This assures that there has been no tampering of either the audit tape or the validator terminal from the time that the lane had been previously closed. The information recorded by the computer unit is printed out on the punch tape unit 25. This information could also be printed on sheets of paper by an output keyboard printer.

After the lane has been opened, it is ready for entering vehicles. When a vehicle enters the lane, the collector sets the keyboard 11 for the proper class of vehicle. Generally, vehicles are classified by the number of axles. For convenience, the keyboard is normally set for a Class 1 vehicle of the general automobile type. For vehicles of other types and those with more axles than regular automobiles, the number must be set on the keyboard. The validator unit will punch the ticket with the vehicle class as set on the keyboard and also the day and time of entry, the interchange and entry lane numbers and the identification number of the collector.

As the vehicle passes the entry lane, the entry vehicle detector 21 will count the total number of axles passing through the lane, and transmit the information to the computer unit 24. The vehicle detector 21 contains a plurality of treadle contacts encased in a closed unit which close with the passage of the vehicle. In addition to counting the number of axles, the treadles also determine whether the vehicle is proceeding through the entry lane in a normal manner or whether it is backing up. In the event the vehicle backs out of the lane, the sequence of the closing of treadle contacts will be in a reverse direction and a signal will be sent to the computer unit 24 to'subtract the number of axles determined from the total. g

A vehicle which is used for maintenance would be provided with a card bearing a specific identification number whose digits differ in number from that of the collector code identification number. In this embodiment, nine digits were used to identify the non-revenue paying vehicles. Similarly,'credit cards can be issued to drivers with a similar number of digits. When a nonrevenue paying vehicle or credit card vehicle approaches the entry lane, the collector inserts the card into the card reader 12. The card reader recognizes the number of digits representing a non-revenue identification number and transmits the number to the computer unit 24. The computer unit checks the number and verifies it as a current valid number. If the number is a valid one, the validator unit will automatically punch a ticket indicating the same information as for a normal cash paying transaction, however, bearing an additional indication representing the non-revenue paying code or a credit charge code. Should the computer recognize the identification number as an invalid number, an alarm will be sounded whereby the collector will be able to apprehend the violator. Should he tabulate information on the unauthorized passage of a vehicle through a closed lane. The vehicle detector would sense the passage of sucha vehicle and if the lane is closed this could be set to trigger a printout from the computer.

At the exit lane, the lane is opened in a similar manner to that described for the entry lane. The toll collector inserts his identification card into the card reader 29 and the computer records information similar to that recorded at the opening of the entry lane. The lane signal 33 will change from red 34 to green 35, indicating to motorists that the exit lane is desire, the collector can then issue a regular cash paying ticket in the normal manner.

At the completion of a tour of duty, the collector again inserts his own identification card into the card reader. The computer will recognize the collector identification number and record that number together with the interchange number, the lane number, the time and the total transactions completed during the collectors tour of duty.

Should a collector neglect to close his lane, when he completes his own tour of duty, at the beginning of the next tour of duty, when the new collector inserts his card the computer will recognize this by the dissimilar collector identification numbers and will first close out the previous totals and then reopen the lane with the new collector number. i

The computer tabulates information for each lane at every hour in addition to the opening and closing of the tour of duty. The information tabulated includes the total axles as counted by the vehicle detector system, the total indicated axles as computed from the classifications registered by the entry validator, and any variance between these numbers. It also computes the number of tickets validated by class of vehicle for each particular lane. In addition, the computer can be set to now open.

To process a normal transaction at the exit lane, the collector retrieves from the driver the toll ticket and inserts it into the ticket reader 27. The ticket reader automatically senses the point of entry and the class of vehicle and transmits this information to the computer unit 24. The computer, usingtable look-up methods, computes the toll, which is transmitted back to the exit validator unit and displayed on the fee display unit 37 for the motorist. The ticket is then automatically passed directly into a ticket storage unit. The computer records for each transaction the collectors identification number, the lane and interchange designation number, the exit time and day of the recording, the computed fee, the entry interchange and lane numbers, the entry time and date, and the classification of the vehicle.

Simultaneously, the computer sets the type wheels on receipt printer 30. The receipt printer contains preprinted paper bearing the exit interchange and lane designation numbers, and under control of the computer, prints the amount of toll, the day, time, entry point and classification of vehicle. The receipt is made available for a driver of the vehicle upon request.

Upon the vehicle leaving the exit lane, the displayed amount on the fee display units 28, 37 is blanked out and the fee display units are ready for the next vehicle.

To process a non-revenue .or credit authorized transaction, the collector inserts the ticket into the ticket reader 27 in a normalmanner. The ticket reader senses the information from the ticket and transmits it to the computer. Should it be a non-revenue ticket, the fee display will indicate by a predetermined code that it represents no fee. Should it be a credit transaction, the fee display 28, 37will display the amount of the toll which will be charged to the drivers account.

The computer unit will record for the opening and closing of each tour of duty as well as hourly, the lane and interchange designation numbers, the total number of tickets read, the transaction totals for each class of vehicles, the total axles counted by the detectors in the vehicle detector system 39, the total axles computed from the information on the tickets and any variance between these last two numbers. Any variance will indicate that the amount of revenues collected do not correspond with the total number of classes of vehicles which have passed through the lane, thereby providing an immediate check on the activities of the collector.

The computer unit indicated at 24 can be placed at each interchange whereby the computer will be able to handle the operations of each of the lanes at that particular interchange. The individual computers would then transmit the totals accumulated to a central computing station at the central data processing center. Alternatively, instead of the individual computers located at each interchange, the terminals can be connected directly to communicate with a large computer at the data processing center which would receive the information from each individual entry and exit lane directly. The amounts charged on the credit cards would be transmitted to the central data processing center to a billing department and bills could automatically be sent out to each credit card holder.

Although a particular embodiment of the closedloop type configuration has been shown and described in FIG. 1, it is understood that variations could be effected without departing from the system approach. For example, the'tickets encoded at the entry lane need not be of the punch card type: Other types of encoding schemes could be substituted. For example, magnetic encoding of the tickets could be easily arranged at the entry lane, and the exit lane would be provided with a magnetic reader instead of the punch ticket reader.

The embodiment as described requires the insertion of the collector's identification card to open the lane. The card is then removed, and a second insertion is required to close the lane. However, the system can be arranged such that the card would remain inserted throughout the tour of duty and only removed at the completion of the tour of duty. Other variations could similarly be made to accommodate for particular requirements.

The exit lane can be arranged to work automatically wherein a customer inserts his ticket by himself and the amount to be paid is automatically computed and displayed. A toll collection machine placed adjacent to the terminal and connected thereto will permit passage of the car after the correct amount has been deposited.

Referring to FIG. 2, there is shown the specific equipment and connections required for the entry lane 10. Items which are the same as in FIG. 1 have like identification numbers. The output signals from keyboard 11 pass through encoder 42 into the shift register 43. Card reader 12 has one output which is fed through the encoder 42 to the shift register 43 and a second output which controls the equipment interlock device 44, and the lane status device 45. Vehicle detector unit 46 feeds automatic counter 47 as well as mechanical counter 48. The count from automatic counter 47 passes through the encoder 42 into the shift register 43. A reset mechanism 49 is connected to the mechanical counter 48 as well as to the entire entry lane system through line 50, as will hereinafter be explained. A clock 51 provides signals to the shift register 43 as well as to the alarm 52. The data from the shift register 43 goes to the computer unit through the data output 53. Data from the computer unit comes in to the entry lane system through the data input 54 into the shift register 43. The information passing through the shift register 43 controls the ticket punch 13 as well as the alarm 52. A manual switch interlock 55 also controls the ticket punch 13.

At the beginning of a tour of duty, the collector inserts his identification card into card reader 12, which sends signals through the encoder 42 and shift register 43 into the computer unit. The insertion of the card will also enable the lane status 45 to indicate it is now open and will enable the equipment interlock 44 to open the lane equipment.

When a vehicle enters the lane, the vehicle detector 46 sends signals to the automatic counter 47 which is transmitted through the encoder 42 and shift register 43 to the computer. The mechanical counter 48 will also directly count the number of axles. The collector will enter the classification of the vehicle on keyboard 11. This information is passed into the computer through the encoder 42 and shift register 43. The computer will then return signals to the unit through shift register 43 to ticket punch 13 which will punch the ticket for the particular vehicle. Upon the presentation of a non-revenue or credit card, the card is inserted into the card reader 12 which reads the number and transmits the information to the computer. lf the computer recognizes the number as an invalid number, the computer will send a signal to the invalid charge alarm 52 which will sound the alarm signal whereby the collector will be able to apprehend the violator. If the computer recognizes the non-revenue identification number as a valid number, it sends signals through the shift register 43 to the ticket punch 13 to punch the ticket in the usual manner but also includes the identification number of the non-revenue or credit card as well as a code indicating it as a non cash paying transaction.

Clock 51 provides the timing to the system as well as providing pulses for the shift register operation. The reset mechanism 49 is used to reset the mechanical counter as well as the other system logic upon the occurrence of a power failure. The manual switch interlock 55 is used for direct control of the ticket punch from the keyboard. This can be used for maintenance operation on the ticket punch and in the event of a computer failure, the manual switch interlock can be engaged whereby the ticket punch is operated manually and tickets can still be prepared.

FIG. 3 shows the system logic for the exit lane. Ticket reader 32 has two outputs; one for a standard Hollerith card through the Hollerith converter 62 and the second for a 90 column card through the 90 column converter 63. Both signals go through shift register 59 and into the computer unit through line 60. Ticket reader 32 also sends signals to card status unit 64. A switch 68 is used to control the two outputs 62 and 63 and the position of the switch is shown on indicator 69.

Card reader 29 sends signals through encoder 58 and shift register 59 through data out 60 to the computer. It also controls the equipment interlock and the lane status 66. Vehicle detector 56 controls the mechanical counter 57 and also sends inputs to the computer unit through shift register 59. Data from the computer unit comes into the shift register on line 61 and is used to control the toll display unit 28 and the receipt printer- 30. Timing for the system comes from clock 67.

The operation of the exit lane will now be explained:

The exit lane is opened at the beginning of a tour of duty in a similar manner to that shown for the entry lane. The card reader 29 senses the presence of a four digit identification code representing the collector's number. it then sends signals through the encoder 58 and shift register 59 to the computer unit to record the appropriate information at the beginning of a tour of duty. It also signals to the lane status unit 66 to open the lane and enables the equipment interlock 65 whereby the exit lane equipment can now be functional.

For a normal-transaction, the ticket is taken from the driver of the vehicle and inserted in ticket reader 32. In this embodiment the exit lane can be used with both standard Hollerith encoded tickets or 90 column code tickets. The reader will automatically sense which card is inserted. Normally the system is engaged to receive 90 column code tickets. Should it sense the presence of a Hollerith code, it automatically closes switch 68 and indicates the presence of the Hollerith code on indicator 69. The Hollerith converter62 is then enabled and the information isread and sent to the shift register 59. The status unit 64 will record the status of the ticket as read by .the reader 32. The information from the shift register goes to the computer on line 60. The computer will calculate the proper fee and signal back on line 61 through the shift register to the toll display unit 28 which will display the toll to be paid. The amount will also besent to receipt printer 30 which will engage the appropriate type to print a receipt which will be available for the driver upon request. When a non-revenue or credit ticket is presented, it is inserted in the ticket reader in the usual fashion and the computer will sense the non cash paying code whereby the toll display unit 28 will either register a no fee amount, or will register'a fee and the computer will automatically charge the credit account ofthe vehicle driver. The vehicle detector unit 56 and mechanical counter 57 are similar to thoseshown for the entry lane. Mechanical switching is not shown; however, it is understood that it can be included on the exit lane similar to that shown for the entry lane.

FIG. 4 shows the interface controlbetween the entry or exit lane and the computer unit. The shift register indicated at 69 can be either the shift register from the exit or entry logic device. The output from the shift register is passed to an intermediary buffer 72 which then transfers the information to the computer accumulator 73. An interrupt device 75 receives an interrupt signal from the exit or entry lane which passes through a device selector 74 to control the shift register 69. The interrupt 75 also receives inputs froma clock 77 which passes througha counter'76. The input from the entry or exit lane comes into the shift registerat 70 and the information from the computer through the shift register 69 to the entry or exit lane leaves through line 71.

The information from the entry or exit lane enters the shift register serially under the control of clock pulses. When an entry or exit lane has information to transmit to the computer, it sends a signal to the interrupt 75. The computer will then use the interrupt signal to determine the address ofthe lane and will enable the device selector 74 so that when the shift register is full, there will be parallel transmission of the information to the buffer and'to the computer accumulator. The computer will then await a further interrupt signal indicating that the entry of exit terminal is ready toreceive information from the computer and the computer will then transmit information through the shift register back to the entry or exit lane terminal.

Referring to FIG. 5, there is shown a second embodiment of the invention for use with a barrier type configuration. In the barrier type system there are no tickets issued but instead toll booths are placed at preset control points along the toll road. The revenues collected at each booth are fixed for each class of vehicle.

The terminal 80 contains a keyboard 81, a card reader 82, a fee display device 83 and a receipt printer 84. Electrical connections are made to the terminal by means of connector board 85 in a locked electrical compartment 86. Lane signal 87 comprising red light 88 and green light 89 are electrically connected by means of line 90 to the terminal connector board 85. A separate fee display unit 91 is electrically connected through line 92 to the terminal connector board 85. A

vehicle detector system containing detecting and counting means is shown at 93 and electrically connected through line 94 to the terminal connector board 85. The terminal is electrically connected by means of line 95 to the computer unit 96. The output of the com puter is recorded onto output unit 97 which may be typically a punch tape unit. Connected to the terminal is an automatic toll collection device 98.

The operation of the terminal is similar to that heretofore described withrespect to the closed-loop system. Initially the lane is closed and the lane indicator 87 has the red light 88 in operation. To open the terminal, the collector inserts his'identification card into card reader 82. This causes the computer to record the previous cumulative totals. The interchange and lane numbers, the collector identification number and the time and date. The computer also opens the lane equipment and causes the green light 89 to be operative.

For each transaction, the collector presses the appropriate class button on the keyboard. The amount of revenue to be collected is displayed both on the terminal display 83 and the customer display 91. The information is also transmitted to the computer unit 96 for tabulation. As the vehicle passes through the terminal, the vehicle detector will count the number of axles and the direction of passage and transmit this information to the computer. The computer will tabulate the axle count from the vehicle detector unit and the axle count from the information encoded onto the keyboard and calculator any variance between these values.

For each transaction, the computer sets the type on the receipt printer so that a receipt will be issued upon request as heretofore described.

To close the lane the collector identification card is again inserted into the card reader whereupon the computer totals the transactions and records the time and date, the collector identification number, and the lane and interchange numbers. The computer will also provide an hourly tally and also a printout each time a vehicle passes through a closed lane.

Non-revenue cards and credit cards are inserted into the card reader for the computer to check their validity. An invalid card will cause the computer to trigger an alarm. If the number should be a valid one, the collector still presses the appropriate class button on the keyboard. However, for the non-revenue card the display will indicate a no-fee amount and for the credit card the display will indicate the fee and the computer will automatically charge the account.

Since the revenues are fixed in the barrier type configuration, it is possible to have automatic toll booths for a fixed class of vehicles. The automatic toll collector 98 is used for that purpose. To change the lane into an automatic lane, the collector must open the lane in the normal manner. He then inserts a safe into the collecting machine 98. The keyboard is set for one particular class of vehicles, usually automobiles. Each time a vehicle passes the detector, the fee display will automatically display the fixed fee to be collected. The display can be arranged to have a red light which will be turned on together with the amount to be paid. After the money is deposited into the collection machine the light can be arranged to change to green.

The computer keeps a tally of vehicles passing through the automatic lane without paying the appropriate fee. Each time such a vehicle passes in violation, the computer will cause an alarm to sound.

It will therefore be appreciated that the invention as described provides a toll revenue system with prompt reconciliation of all pertinent collector data. In the closed-loop configuration it provides an accumulated 1 count of the number of vehicles for which transit tickets have been issued at each entry point, and a further accumulation of the number of vehicles and tickets issued for each class of vehicle. A variance, if any, between the actual vehicle count and the number of vehicles for which total tickets have been issued at each lane is automatically computed. All the data can be directly processed by a central office without requiring additional keypunching operation or transporting of encoded tickets. In the barrier type configuration it provides a check on the accuracy of revenues collected and permits the use of automatic toll booths which are also mentioned. The system further provides the availability of offering charge accounts to patrons and permitting a check of valid credit and non-revenue cards. Repairmen will also be issued identification cards which must be inserted into the card reader before repairs commence. This will present any manipulation of the terminals by unscrupulous repair personnel.

It will be further appreciated by those skilled in the art that the data which is available at the computer unit can be further classified to provide an accurate financial record and accounting of each terminal according to each collectors tour of duty. The data can be further used to determine the number and class of vehicles entering and exiting a toll road or passing a particular barrier, to determine which lanes are most heavily used; where the traffic goes to; and all other traffic patterns necessary for a complete road study analysis.

There has been disclosed heretofore the best embodiment of the invention presently contemplated. However, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit of the invention.
