Private Trucking/State-based Truck Credentialing and Inspection Agency
Existing Capabilities
New Capabilities
Speed warning signs with fixed maximum speed suggestion based on assumptions.
Individually calculated maximum curve speed for vehicles based on various factors (weather, road surface, vehicle weight, center of gravity, etc).
Freight trucks have to stop for Enforcement Agency inspections.
Wireless roadside inspections will allow monitoring of truck operators and cargo without costly delays.
Truck weight checks at state and national borders along with credentialing of operator and cargo.
Virtual weigh stations along the roadside and electronic screening of cargo credentials eliminating redundant manual inspections.
Heavy trucks act as moving bottlenecks that increase stop and go traffic near urban freight facilities. 
Traffic signals near freight facilities enable green waves that match heavy truck accelerations to smooth traffic flow in the area. 
Trucks spend a lot of time at facilities waiting their turn to load and unload on fixed schedules. 
Real-time drayage assigns slots based on actual predicted arrival times to reduce waiting and idling.

Value/Why Would Stakeholder Shift to Using a Core?
Potential of significantly increasing safety of truck operations, thus eliminating losses for logistics companies.
Safety applications could allow for increase of vehicle size  without trading off safety.
Electronic monitoring and inspections reduce unproductive stop times while enabling enforcement agencies to reduce staff or refocus staff on other areas.

Alternatives to Using a Core System
Blind spot monitors already in use on modern freight trucks.
Warning systems such as bridge height warnings using laser measurement systems are also deployed in small numbers at vital infrastructure sites.  H expensive and therefore not in widespread use.
Moreover, they are not that effective due to the ambiguity of which vehicle triggered the warning lights.  Drivers often assume it is another vehicle.  The in-vehicle warnings enabled by connected vehicle applications make it clear to the driver that the warning is for them.

Static weigh stations require vehicles to pull over for weighing and inspection.  Only a fraction of vehicles are checked.  Downstream stations would not know if a particular vehicle has been screened and certified at an upstream station so it may be unnecessarily rechecked.
Weigh in Motion stations exist at a number of places to screen for overweight vehicles without requiring trucks to pull over.  They are expensive and require annual or more frequent recalibration to maintain their modest accuracy.

The connected vehicle environment creates a single platform for trucks to communicate with the regulatory infrastructure, the traffic control system, their fleet managers, intermodal and freight facilities and others in a way that would be prohibitively expensive if done by application specific systems.  The new capabilities stem from the efficiency and security of the communications provided by the Core System.
