Vehicle to Infrastructure (V2I) cooperative technology is one of the V2X technologies that play an increasing role in informing connected vehicles about speed, traffic warnings, the time-to-red, time-to-green of traffic lights, etc. As Singapore moves forward to improve the future traffic management system, the efficacy of Dedicated Short-Range Communications (DSRC) beacons have been tested and deployed at various places in Singapore.
DSRC is a highly secure, high-speed two-way short-to-medium-range wireless communication function used between vehicles and infrastructure. Robust in the face of radio interference and interference from distant sources, it permits very high data transmission critical in communications-based active road safety applications which brings about increased safety and improved adjustability.
The system also provides real time notifications, backend data and reports, which also facilitate better reaction timings, reporting efficiency, and trend analysis, consequently reducing the need for laborious physical monitoring.
