In this report we present a framework to assist Intelligent Transportation Systems (ITS) providers in the deployment of ITS user services requiring wide-area wireless communi-cations. We examine a scenario in the San Francisco East Bay Area for the 1995 time frame and determine the applicable ITS user services and wide-area wireless messaging requirements. Using the programming language SHIFT we investigate the uplink perfor-mance of a leading wireless candidate, Cellular Digital Packet Data in terms of its ability to support vehicle-to-roadside ITS applications during normal peak-period conditions and during a major incident.
