RSE Intersection Management Functional Area
Description
'RSE Intersection Management' uses short range communications to support connected vehicle applications that manage signalized intersections. It communicates with approaching vehicles and ITS infrastructure (e.g., the traffic signal controller) to enhance traffic signal operations. Coordination with the ITS infrastructure also supports conflict monitoring to ensure the RSE output and traffic signal control output are consistent and degrade in a fail safe manner.
Included In
Functional Requirements
| ID | Requirement |
|---|
| 01 | The field element shall communicate with passing vehicles to provide the current signal phase and timing information for all lanes and approaches at a signalized intersection. |
|---|
| 02 | The field element shall send the request for emergency vehicle preemption to a traffic signal controller that results in preemption of the current control plan and grants right–of–way to the requesting vehicle. |
|---|
| 03 | The field element shall send the infrastructure application status to the operations center. |
|---|
| 04 | The field element shall send the request for commercial vehicle priority to a traffic signal controller that results in priority of the current control plan and grants right–of–way to the requesting vehicle. |
|---|
| 05 | The field element shall receive transit signal priority requests from transit vehicles and forward to the traffic signal controller |
|---|
| 06 | The field element shall receive emergency vehicle preemption requests from emergency vehicles and forward to the traffic signal controller. |
|---|
| 07 | The field element shall determine when special vehicles requesting preemption or priority at a signal are authorized to do so based on their digital credentials. |
|---|
| 08 | The field element shall send a signal service request to the traffic signal controller when its application status determines the need for a signal change. |
|---|
| 09 | The field element shall collect current signal phase and timing data from the traffic signal controller |
