Project Description: LeeTran proposed a project to procure and install On–Board Units (OBU's) that will integrate Signal Priority elements within the US 41 FRAME project.
1: The ITS Object shall obtain security policy information from the Cooperative Intelligent Transportation System Credentials Management System (CCMS).
1: The ITS Object shall provide its network address, service offerings and metrics characterizing those services to vehicles within the broadcast range of the ITS Object's short range communications equipment.
2: The ITS Object shall provide its network address, service offerings and metrics characterizing those services to the Object Registration and Discovery Service.
3: The ITS Object shall obtain network addresses from the Object Registration and Discovery Service.
4: The ITS Object shall make network address information available to onboard applications.
5: The ITS Object shall provide its configuration and operational status information to the Service Monitor
6: The ITS Object shall acquire regulatory information relevant to the operation of the ITS Object from the CCMS.
1: The ITS Object shall obtain security policy information from the Cooperative Intelligent Transportation System Credentials Management System (CCMS).
10: The ITS Object shall maintain cryptographic secret information so that those secrets are accessible only to ITS Security Support, and not to any other Functional Object.
11: The ITS Object shall request pseudonymous credentials from the CCMS.
12: The ITS Object shall provide messages (that it receives) that indicate potential misbehavior/malfunction to the CCMS.
2: The ITS Object shall request enrollment credentials from the CCMS.
3: The ITS Object shall obtain the CCMS' trust credentials.
4: The ITS Object shall provide a mechanism for on-board applications to digitally sign messages using keys secured by the CCMS' trust authority.
5: The ITS Object shall provide a mechanism for on-board applications to authenticate messages secured by the CCMS' trust authority.
6: The ITS Object shall provide a mechanism for on-board applications to encrypt messages using keys secured by the CCMS' trust authority.
7: The ITS Object shall provide a mechanism for on-board applications to decrypt messages using keys secured by the CCMS' trust authority.
8: The ITS Object shall obtain a list of revoked credentials from the CCMS.
9: The ITS Object shall make the list of revoked credentials available to on-board applications.
1: 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.
5: The field element shall receive transit signal priority requests from transit vehicles and forward to the traffic signal controller
8: 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.
9: The field element shall collect current signal phase and timing data from the traffic signal controller.
1: The field element shall collect traffic-related data including snapshots of measured speed and heading and events including starts and stops, speed changes, and other vehicle control from vehicles.
2: The field element shall collect provide vehicle situation data to a center for archival.
3: The field element shall provide data collection parameters to vehicles.
1: The center shall remotely control traffic signal controllers.
10: The center shall adjust signal timing in respond to a signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other requests for right-of-way.
4: The center shall collect traffic signal controller fault data from the field.
6: The center shall implement control plans to coordinate signalized intersections based on data from sensors.
1: The transit vehicle shall determine the schedule deviation and estimated times of arrival (ETA) at transit stops.
2: The transit vehicle shall send priority requests to traffic signal controllers at intersections, pedestrian crossings, and multimodal crossings on the roads (surface streets) and freeway (ramp controls) network that enable a transit vehicle schedule deviation to be corrected.
1: The Vehicle shall make basemap, roadway geometry, intersection geometry and parking facility geometry information available to other onboard vehicle applications.
3: The center shall define business rules that govern use of transit vehicle signal priority, communicate these rules to the transit vehicle, and monitor transit vehicle requests for priority at signalized intersections.
