Maint and Constr Vehicle OBE --> Connected Vehicle Roadside Equipment:
vehicle location and motion
Definitions
vehicle location and motion (Information Flow): Data describing the vehicle's location in three dimensions, heading, speed, acceleration, braking status, and size.
Maint and Constr Vehicle OBE (Source Physical Object): The 'Maint and Constr Vehicle OBE' resides in a maintenance, construction, or other specialized service vehicle or equipment and provides the processing, storage, and communications functions necessary to support highway maintenance and construction. All types of maintenance and construction vehicles are covered, including heavy equipment, supervisory vehicles, unmanned remote controlled field maintenance robots, and sensory platforms that may be wheeled or low altitude aerial vehicles (e.g. drones, balloons). The MCV OBE provides two-way communications between drivers/operators and dispatchers and maintains and communicates current location and status information. A wide range of operational status is monitored, measured, and made available, depending on the specific type of vehicle or equipment. A snow plow for example, would monitor whether the plow is up or down and material usage information. The Maint and Constr Vehicle OBE may also contain capabilities to monitor vehicle systems to support maintenance of the vehicle itself. A separate 'Vehicle OBE' physical object supports the general vehicle safety and driver information capabilities that apply to all vehicles, including maintenance and construction vehicles. The Maint and Constr Vehicle OBE supplements these general capabilities with capabilities that are specific to maintenance and construction vehicles.
Connected Vehicle Roadside Equipment (Destination Physical Object): 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.

Basis | This data is intentionally transmitted to everyone via a broadcast. Much of its information content can also be determined via other visual indicators | Incorrect information could lead to the system not operating properly. If the system does not properly know where the emergency vehicle is coming from and where it is heading, the system could incorrectly route traffic in an attempt to speed up the emergency vehicle. If it is making logic decisions based on incorrect data, this could prevent the emergency vehicle from navigating through the intersection quickly. | This data is required for the Emergency Vehicle Preemption to operate properly. If this data is not available, the emergency vehicle may not be able to travel through the intersection quickly enough. If an emergency vehicle is not able to get through the intersection quickly enough, it could prevent them from responding to the emergency in a timely manner. As discussed above, the difference between success and failure of this application is not catastrophic, but it is significant, so a moderate availability rating seems appropriate. |
