ATMS21-Roadway Closure Management (Service Package*)

Description

This service package closes roadways to vehicular traffic when driving conditions are unsafe, maintenance must be performed, and other scenarios where access to the roadway must be prohibited. The service package includes automatic or remotely controlled gates or barriers that control access to roadway segments including ramps and traffic lanes. Remote control systems allow the gates to be controlled from a central location or from a vehicle at the gate/barrier location, improving system efficiency and reducing personnel exposure to unsafe conditions during severe weather and other situations where roads must be closed. Surveillance systems allow operating personnel to visually verify the safe activation of the closure system and driver information systems (e.g., DMS) provide closure information to motorists in the vicinity of the closure. The equipment managed by this service package includes the control and monitoring systems, the field devices (e.g., gates, warning lights, DMS, CCTV cameras) at the closure location(s), and the information systems that notify other systems of a closure. This service package covers general road closure applications; specific closure systems that are used at railroad grade crossings, drawbridges, reversible lanes, etc. are covered by other ATMS service packages.

Transaction Set Diagram

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.

  1. The Traffic Management Subsystem remotely controls the operation of gates or barriers (barrier system control) used to control access to roadways. Operational status of the gates or barriers may be monitored by the Traffic Management Subsystem (barrier system status).

  2. The Traffic Management Subsystem may obtain images (traffic images) from surveillance equipment on the Roadway. In addition to monitoring traffic conditions, the equipment can be used to monitor the operation of barrier systems. The equipment is controlled (pan, tilt, and zoom) (video surveillance control) by the Traffic Management Subsystem.

  3. The Traffic Management Subsystem controls (roadway information system data) and monitors (roadway information system status) driver information systems such as DMS and HAR at the Roadway, providing driver information including the current status of barrier systems and times of closures and openings. The barrier system itself may communicate directly with driver information equipment at the Roadway to provide road closure information (roadway equipment coordination).

  4. When a gate or barrier system is deployed, thus limiting access to a roadway, the Traffic Management Subsystem notifies (road network conditions) the Information Service Provider, Emergency Management, Transit Management, and Maintenance and Construction Management Subsystems.

  5. The Emergency System Operator can initiate a request for operation of gates or barriers in order to close roads (part of emergency operations inputs). The request is forwarded from the Emergency Management Subsystem to the TMS(emergency traffic control request or road closure notification). The TMS will provide information back to the Emergency Management Subsystem regarding the gate or barrier actions they have taken (emergency traffic control information). This information will be passed to the Emergency System Operator (as part of emergency operations status).

  6. The entire process is under the asynchronous monitoring (traffic operator data) and control (traffic operator inputs) of Traffic Operations Personnel.

  7. The Maintenance and Construction Management Subsystem may also remotely controls the operation of gates or barriers (barrier system control) used to control access to roadways. Operational status of the gates or barriers may be monitored by the Maintenance and Construction Management Subsystem (barrier system status).

  8. The Maintenance and Construction Management Subsystem may also obtain images (traffic images) from surveillance equipment on the Roadway. In addition to monitoring traffic conditions, the equipment can be used to monitor the operation of barrier systems. The equipment is controlled (pan, tilt, and zoom) (video surveillance control) by the Maintenance and Construction Management Subsystem.

  9. The Maintenance and Construction Management Subsystem controls (roadway information system data) and monitors (roadway information system status) driver information systems such as DMS and HAR at the Roadway, providing driver information including the current status of barrier systems and times of closures and openings.

  10. The set of Maintenance and Construction Management interfaces is under the asynchronous monitoring (maint and constr operations information presentation) and control (maint and constr center personnel inputs) of Maintenance and Construction Center Personnel.

  11. The Maintenance and Construction Vehicle Subsystem may also remotely controls the operation of gates or barriers (barrier system control) used to control access to roadways. This control is initiated by the Maintenance and Construction Field Personnel (as part of maint and constr field personnel inputs). Operational status of the gates or barriers may be monitored by the Maintenance and Construction Vehicle Subsystem (barrier system status). The status is passed along to the Maintenance and Construction Field Personnel (as part of maint and constr field personnel information presentation).

  12. Finally, the Emergency Vehicle Subsystem may remotely controls the operation of gates or barriers (barrier system control) used to control access to roadways. This control is initiated by the Emergency Personnel (as part of emergency personnel inputs). Operational status of the gates or barriers may be monitored by the Emergency Vehicle Subsystem (barrier system status). The status is passed along to the Emergency Personnel (as part of emergency personnel information presentation).
