D.C. plans bus priority traffic signaling

The Washington, D.C., Department of Transportation says it is looking to install transit signal priority equipment at 103 locations throughout the city to help usher buses through heavy traffic. The DOT says the TSP system will signal buses via traffic controller box and will adjust traffic signal timing automatically to accommodate the buses. Officials say the Federal Transit Administration will fund the project with $58.8 million TIGER grant provided in 2010.
