Connected Vehicle Roadside Equip - Mobility
Status: Planned
Description
Connected Vehicle Roadside equipment includes Road Side Units (RSU) that are short range to medium range wireless communication radios (one or two way) specifically designed for communications from the infrastructure to the vehicle for notification of signals, construction zones, fire pre–emption and provides a way for vehicles to communicate directly with roadside equipment. DSRC is equipped with a camera for mapping. This element includes the roadside equipment that performs vehicle infrastructure integration, data collection and dissemination. '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 near 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.
Stakeholders
Physical Objects
Functional Objects
| Functional Object | Description | User Defined |
|---|
| RSE Data Subscription Management | 'RSE Data Subscription Management' manages data subscriptions for an RSE. It provides access to a catalog of available data, manages the necessary identification information and rules that govern the data subscriptions, supports communications with data providers to collect data per the subscription rules, and makes the data available to other RSE applications. It supports different mechanisms for collecting data including one–time query–response as well as publish–subscribe services. | False |
|---|
| RSE Parking Management | 'RSE Parking Management' monitors the basic safety messages generated by connected vehicles to detect vehicles parking and maintain and report spaces that are occupied by connected vehicles. It also uses short range communications to provide parking information to vehicles. | False |
|---|
| RSE Restricted Lanes Application | The 'RSE Restricted Lanes Application' uses short range communications to monitor and manage dynamic and static restricted lanes. It collects vehicle profile information from vehicles entering the lanes and monitors vehicles within the lanes, providing aggregate data to the back office center. It provides lane restriction information and signage data to the vehicles and optionally identifies vehicles that violate the current lane restrictions. These functions are performed based on operating parameters provided by the back office managing center(s). | False |
|---|
| RSE Traveler Information Communications | 'RSE Traveler Information Communications' includes field elements that distribute information to vehicles for in–vehicle display. The information may be provided by a center (e.g., variable information on traffic and road conditions in the vicinity of the field equipment) or it may be determined and output locally (e.g., static sign information and signal phase and timing information). This includes the interface to the center or field equipment that controls the information distribution and the short range communications equipment that provides information to passing vehicles. | False |
