VEHICLE PROBES AS REAL-TIME ATMS SOURCES OF DYNAMIC O-D AND TRAVEL TIME DATA

This paper has two main objectives. First, the process of obtaining network traffic data from probe vehicles is examined such that statistical sampling equations can be developed that provide both theoretical and practical estimates of the reliability of these probe data. Second, using an example network, the traffic simulation model results are compared against the analytical results. The validation of simulation based results permits the simulation model to be used for more complex situations, for which statistical analyses are no longer practical, and to determine the overall impact of the various statistical approximations that had to be made within the analytical solutions.
