Emergency Response/Pre-Emption
Existing Capabilities
New Capabilities
Current technology transmits optical signal to request preemption therefore requires line-of-sight communication.
 
 
Ability to request preemption for an actual path along its intended route. 
 
Exact timing of preempt based on actual traffic conditions.
Clear path for emergency vehicles quickly without generating confusion among drivers.
Warning to individual vehicles to clear path.
Alert emergency management agency / dispatch to accidents and dispatch resources necessary.
Give precise information on location and potential severity of injuries based on actual vehicle speed prior to accident.
Medical information and crash details communicated to medical and rescue facilities by radio after responders arrive. 
Vehicle crash data provides real-time information about the crash: number of victims, potential injuries and need for extraction equipment.

Value/Why Would Stakeholder Shift to Using a Core?
Save more lives.
Strategically resolve signal preemption priorities in real-time beyond the vicinity of one intersection.
Manage traffic flow in the vicinity to minimize disruption to non-priority traffic.
Warn vehicles in traffic beyond the line of site of the approaching Emergency Vehicle.

Alternatives to Using a Core System
Optical and acoustic line of sight systems and short range radio beacons are currently in use but most of these systems only operate one intersection ahead.
Beacon signals are subject to blockage and interference.
They provide little time for traffic ahead to respond and offer nothing to aid recovery of traffic flow.
Only the secure and pervasive communications that a Core System provides for the connected vehicle environment will allow an emergency vehicle to communicate with the infrastructure and individual vehicles using the same system.

Proprietary in-vehicle systems (like Onstar) automatically contact 911 through an operator.  Connected vehicle makes this possible for all vehicles without regard to make or manufacturer of the vehicle and hardware and at much lower cost than trying to integrate various commercial systems.  Connected vehicle has the potential to provide more information than commercial 911 systems.  Furthermore, since no subscription is required  obtaining this data via a Core System lowers the cost for both drivers and emergency responders.
