Process and system for ascertaining traffic conditions using stationary data collection devices

摘要

A process and apparatus for determining traffic conditions using stationary data collection devices that are installed in a road network. The data collection devices collect data about traffic conditions at the respective installation sites in keeping with an established measurement and then forward the collected information to a traffic center in keeping with an established reporting procedure where the data is analyzed to determine the traffic condition. At least a portion of the results of the analyses of the traffic center is transmitted to particular data collection devices. The measurement and reporting procedures of the particular data collection devices are modified or influenced based on the results of the analyses of the traffic center and as a result the data transmissions between the traffic center and data collections devices are substantially reduced.
