Dedicated Short-Range Communication

Dedicated Short-Range Communication (DSRC) is a wireless communication technology designed to allow automobiles in the intelligent transportation system (ITS) to communicate with other automobiles or infrastructure technology.

A wireless technology for vehicular traffic. Using a modified 802.11, a technology for North American cars and trucks, DSRC is designed for several applications. For example, ambulances can cause traffic lights down the road to change in their favor, and traffic congestion can be transmitted to automobile navigation systems. It allows vehicles to sense that they are about to crash, and the safety systems can begin to tighten seatbelts and warm up the airbags before impact. In addition, a standard for wireless payment allows parking lots and fast-food drive-ins to offer the same convenience as the automated highway toll systems such as E-ZPass.As the most developed communication technology for V2X, Dedicated Short-Range Communication (DSRC) came into being in the 1990s. In the past 20 years, various governments, standard institutions and OEMs have invested heavily in DSRC technology development and application. Up til now, the US, European Union and Japan have all developed separate standards of DSRC.
