Physical Objects
Functional Objects
| Functional Object | Description | User Defined |
|---|
| Roadway Basic Surveillance | 'Roadway Basic Surveillance' monitors traffic conditions using fixed equipment such as loop detectors and CCTV cameras. | False |
|---|
| Roadway Restriction Monitoring and Warning | 'Roadway Restriction Monitoring and Warning' measures the size and weight of passing vehicles and displays warnings to vehicles if the size exceeds the current infrastructure restrictions. The measured vehicle dimensions are also made available to other applications. | False |
|---|
| Roadway Warning | 'Roadway Warning' includes the field equipment used to warn drivers approaching hazards on a roadway. Warnings may be generated in response to roadway weather conditions, road surface conditions, traffic conditions including queues, obstacles or animals in the roadway, and any other transient events that can be sensed. The equipment monitors traffic and roadway conditions and may send data to a Traffic Management Center for processing or may process it to determine when a warning should be issued. When it is determined that a warning should be issued, the equipment is used to alert approaching drivers via dynamic warning signs, flashing lights, in–vehicle messages, etc. | False |
|---|
| RSE Infrastructure Restriction Warning | 'RSE Infrastructure Restriction Warning' uses short range communications to warn vehicles of infrastructure dimensional and weight restrictions. | False |
