San Jose Integrates Emergency Vehicle Pre-Emption with CAD System
Monday, October 01, 2018 | Comments

San Jose, California, continues to roll out a centralized emergency vehicle pre-emption (CEVP) solution using software to interface between TransCore’s traffic signal management system and Intergraph’s CAD system.

This interface communicates and coordinates an emergency response vehicle location via GPS to the Department of Transportation (DOT) traffic signal management system and turns traffic signals green along the response route to clear standing vehicles that can impede response and allow emergency vehicles to proceed through intersections safely.

System tests began in January, and a full-scale deployment began July 30.

There are 101 intersections operating under the new CEVP system. The remaining 854 intersections are projected to be completed by December. The new CEVP system only functions at city of San Jose-managed signalized intersections and will not operate at county and some state traffic signals. The existing optical-based pre-emption system at about 336 intersections will remain in place to support mutual-aid emergency response by neighboring agencies whose CAD systems are not integrated with the city of San Jose’s CEVP system.
