Physical Objects
Functional Objects
| Functional Object | Description | User Defined |
|---|
| RSE Infrastructure Restriction Warning | 'RSE Infrastructure Restriction Warning' uses short range communications to warn vehicles of infrastructure dimensional and weight restrictions. | 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 |
|---|
| RSE Wrong Way Vehicle Warning | 'RSE Wrong Way Vehicle Warning' detects and warns wrong way vehicles using V2I communications. It provides an interface with other field equipment that detects wrong way vehicles using infrastructure–based sensors. | False |
