Safe-D: Safety through Disruption

Signal Awareness Applications


Abstract

Intersection collisions account for 40% of all crashes on our nation’s roadways. It is estimated that 165,000 accidents, resulting in approximately 800 fatalities annually, are due to vehicles that pass-through intersections during red signal phases. Although infrastructure-based red-light violation countermeasures have been deployed, intersections remain a top location for vehicle crashes.

The Virginia Department of Transportation, along with its research arm, the Virginia Transportation Research Council partnered with the Virginia Tech Transportation Institute to create the Virginia Connected Corridors (VCC), a connected vehicle test bed, located in Fairfax and Blacksburg, Virginia, that enables the development and assessment of early stage connected and automated vehicle applications. Recently, new systems have been deployed that transmit position correction messages to support lane-level accuracy, enabling signal awareness applications such as Red-Light Violation Warning to be developed. VTTI has developed and deployed a number of VCC platforms that can be used to test CV application exchanges with drivers, but such platforms are currently not capable of informing drivers of unsafe approaches to intersections. However, the new position correction capabilities will allow the development of signal awareness applications, which represent a disruptive technology that can promote safer, and more economic and ecologically-friendly driving.

This project proposes to enhance the current capabilities of VCC platforms by developing new signal awareness safety and mobility features. In addition, this project will investigate the technical and human factors constraints associated with user interfaces for notifying and alerting drivers to pertinent intersection-related information to curb unsafe driving behaviors at signalized intersections.
