Mobility Services for individual drivers
Existing Capabilities
New Capabilities
Fixed speed cruise control.  Drivers must manually observe gap, conditions and brake lights.  Some applications of Adaptive Cruise Control (ACC) which uses autonomous sensors to maintain gap distance.
Cooperative Adaptive Cruise Control (CACC) or inter-vehicle communication to maintain gap and speed between vehicles.  Possibility to form platoons of vehicles when penetration is high.   Optimal speed can be derived in TMC and sent to vehicles.
GPS-based route guidance. Real-time information is spotty and infrequently updated if used at all. 
Route guidance incorporating real-time traffic, construction, weather and pavement conditions. 
Pre-trip web information on parking. 
Real-time, dynamic parking availability delivered to the driver. 
Radio traffic reports, infrastructure-based dynamic message signs (DMS) and flashing lights to provide generic traveler information. 
Real-time localized in-vehicle warnings of queues, shock waves, lane closures, merges, and speed changes due to traffic, incidents or work zones.

Value/Why Would Stakeholder Shift to Using a Core?
Enhanced Safety.
Shorter travel times.
Smoother traffic flow with higher throughput.
Less stressful travel.

Alternatives to Using a Connected Vehicle Core System
Conventional cruise control, ACC and commercial GPS navigation systems provide some of these capabilities but at a lower level of functionality.  Driver information sources exist but are not predictive or dynamic at a scale that can benefit drivers in real-time during a trip.
Real-time parking information is not currently available to drivers except via DMS or radio in rare cases.
DMS and Variable Speed Limit signs can currently be used to adjust speed limits but are advisory in nature and seldom obeyed.  The ability to set and modify speed limits from a central location and send these messages directly to vehicles (either as advisory messages or to control platoon speed) allows traffic managers a greater level of control over traffic outcomes.
Automated platooning to increase traffic density and throughput would also be new.
