ITS Roadway Equipment --> Light Vehicle Driver:
driver information
Definitions
driver information (Information Flow): Regulatory, warning, guidance, and other information provided to the driver to support safe and efficient vehicle operation.
ITS Roadway Equipment (Source Physical Object): 'ITS Roadway Equipment' represents the ITS equipment that is distributed on and along the roadway that monitors and controls traffic and monitors and manages the roadway. This physical object includes traffic detectors, environmental sensors, traffic signals, highway advisory radios, dynamic message signs, CCTV cameras and video image processing systems, grade crossing warning systems, and ramp metering systems. Lane management systems and barrier systems that control access to transportation infrastructure such as roadways, bridges and tunnels are also included. This object also provides environmental monitoring including sensors that measure road conditions, surface weather, and vehicle emissions. Work zone systems including work zone surveillance, traffic control, driver warning, and work crew safety systems are also included.
Light Vehicle Driver (Destination Physical Object): The 'Light Vehicle Driver' represents the person that operates a light vehicle on the roadway. This physical object covers the interactions that are specific to light, passenger vehicles. See also the 'Driver' physical object that covers interactions that are shared by operators of light, transit, commercial, and emergency vehicles where the interactions are not particular to the type of vehicle.

| Interoperability | Description |
|---|---|
| Not Applicable | Interoperability ratings don't apply per se to some types of interfaces like human interfaces. These interfaces may still benefit from associated standards (e.g., ergonomic and human factors standards for human interfaces), but the primary motive for these standards is not interoperability. |

| Basis | This data is sent to all drivers and is also directly observable, by design. | This is the primary signal trusted by the driver to decide whether to go through the intersection and what speed to go through the intersection at; if it's wrong, accidents will happen. | If the lights are out you have to get a policeman to direct traffic – expensive and inefficient and may cause a knock-on effect due to lack of coordination with other intersections. | |
