COMMUNICATION LOAD REQUIREMENTS FOR ALTERNATIVE ATIS ARCHITECTURES
This paper provides estimates of vehicle-infrastructure communication load requirements for several alternative architectures characterized by three key attributes: vehicle-infrastructure communication system, location of the route-selection function, and degree of coupling between route selection and traffic control. Four communication technologies were considered: wide-area broadcast radio, cellular radio, localized beacons, and FM subcarrier. The methodology involved estimating traffic and communication system parameters, defining communication messages, and estimating message lengths and transmission frequencies. The load requirements depend highly on the key attributes of the architectures as well as the vehicle traffic and communication system parameters. Based on the results, several hybrid approaches to providing for the communication requirements were identified.
