A new system of electronic signs and traffic signal meters that will allow drivers to quickly get around major accidents clogging up Interstate 15 is set to go into effect Thursday, according to the San Diego Association of Governments, the region's planning agency, and Caltrans.

The Integrated Corridor Management project is a series of electronic signs on I-15, alternate route signs and coordinated traffic signal and ramp meters. If an accident causes significant slowdowns, drivers will see a message on the electronic signs with instructions on when to get off I-15 and what route to follow. Traffic lights along the route will be set to allow them to get back on the freeway as soon as possible, the agencies said.

The system will cover 20 miles of I-15, from just north of State Route 52 to State Route 78.
