Maintenance, Operations and Enhancement of DSRC Communications Infrastructure

The United States Department of Transportation (U.S. DOT) provided financial and technical support to California Department of Transportation (Caltrans) and PATH for updating the Dedicated Short Range Communication (DSRC) communication infrastructure of its test-bed site along El Camino Real in Palo Alto. That infrastructure needs to be maintained and supported so that it will be useful for other Caltrans and PATH projects, as well as for projects to be conducted by a variety of other public and private sector organizations in the region. Caltrans and the University of California PATH Program have been collaborating on the development, testing and evaluation of DSRC for a decade, beginning with the VII California project. DSRC at 5.9 GHz provides a unique capability to deliver time-critical, safety-critical messages between the roadside infrastructure and vehicles with high reliability and low latency. Work under this project will maintain the test-bed, provide support to the new users, provide liaison to National network of test-beds, upgrade and enhance test-bed capabilities and perform a radio coverage study of the 11 intersections. This radio coverage study will investigate areas where the radio coverage is insufficient and areas where there is an overlap of the two adjacent radios. This study will present solutions to the problems of insufficient radio coverage and overlap areas.
