A promising wireless technology called Dedicated Short Range Communications, or DSRC, is a communication standard used for the exchange of safety-critical and time-critical information between roadway infrastructure and vehicles. The U.S. Department of Transportation is encouraging the development of DSRC, which has been rapidly improving in recent years. Having up-to-date test beds on public roadways is essential to testing and developing the technology even further. PATH and Caltrans are upgrading their Palo Alto test bed so that it can become a key element in the national network of DSRC test beds. This location is especially crucial as several major international vehicle manufacturers have built research facilities in the area.
