Paul Gray B.Eng., M.Eng., Ph.D. Cohda Wireless

In 2010 Cohda Wireless conducted a feasibility study for the use of Dedicated Short Range Communications (DSRC) for improving rail level crossing safety.

DSRC is the globally coordinated standard for Cooperative Intelligent Transportation Systems (ITS). It combines GPS and wireless communication in dedicated spectrum at 5.9GHz. Safety-of-life applications, such as cooperative collision avoidance are the key feature of DSRC, and the 5.9GHz spectrum includes a communications channel dedicated to cooperative safety applications.

Vehicles use DSRC to share information by continually broadcasting their location, speed, direction, vehicle type and size, and additional status information. The DSRC system also includes a processor that uses local position information, and information received from other vehicles, to accurately detect potential collisions and activate driver warnings. DSRC Roadside Equipment (RSE) allows communications between vehicles and infrastructure, such as railway warning systems.
