Methods for decision making about sensor location/configuration for traffic sensing and routing are described. Construction of predictive models via machine learning that infer variance of road speeds, in general or for specific contexts (e.g., rush hours for a traffic system) occurs. The predictive...http://www.google.com/patents/US7948400?utm_source=gb-gplus-sharePatent US7948400 - Predictive models of road reliability for traffic sensor configuration and routing
