DSRC/WAVE ENABLED CONNECTED VEHICLES INFRASTRUCTURE

Connected vehicles enabled through the installation of IEEE WAVE/DSRC standard-compliant radios in vehicles and on roadside units (RSU) that operate on DSRC bands will enable multiple innovations that promote safety and efficiency. An example are is intelligent signalized intersections that allow an RSU at the intersection to obtain real-time information about traffic at intersections. This may reduce the likelihood of collisions and delay through enhanced traffic control means such as broadcasting of suitable warnings or emergency messages. Key to the above is the performance of the 802.11p/WAVE standard, which is based on a design intended largely for low-mobility, single-hop, non delay-critical applications. Many of the protocol stack modifications proposed for the necessary low-latency, potentially multi-hop broadcast remain un- tested in operational scenarios. This effort centered around evaluating DSRC in real-world environments and its potential for integration into a UW PacTrans test-bed for an intelligent signalized intersection.Pacific Northwest Transportation Consortium US Department of Transportation Noki
