Palm Beach County, Florida is installing the Priority One traffic system, which connects the GPS to its emergency vehicles and could cut 20% from
the response time, depending on the intersection and time of day (as found by two Illinois towns currently using the system). The GPS system is based
upon a set of 24 GPS satellites tracking the position of emergency vehicles. As the vehicle approaches a traffic light, it transmits a signal interrupting
the normal cycle, which allows the emergency vehicle to go through it without stopping.
The GPS system will also allow dispatchers to figure out who is closer to an emergency. The cost is about $4000 per intersection and $2000 per truck.
