An emergency vehicle signal preemption system in Houston, Texas reduced emergency vehicle travel time by 16 to 23 percent.
Field tests were run to measure travel time for emergency vehicles (without sirens activated) before and after installation at 22 intersections within two fire districts (11 per district). After a year of operations, the average emergency vehicle travel time decreased 16 percent in one district, and 23 percent in the other.
