ATMS20-Drawbridge Management (Service Package*)

Description

This service package supports systems that manage drawbridges at rivers and canals and other multimodal crossings (other than railroad grade crossings which are specifically covered by other service packages). The equipment managed by this service package includes control devices (e.g., gates, warning lights, dynamic message signs) at the drawbridge as well as the information systems that are used to keep travelers apprised of current and forecasted drawbridge status.

Reduce the regional average travel time index by X percent per year. Travel time index (the average travel time during the peak period, using congested speeds, divided by the off-peak period travel time, using posted or free-flow speeds).
Reduce total energy consumption per capita for transportation by X percent by year Y. Total energy consumed per capita for transportation.
Reduce total fuel consumption per capita for transportation by X percent by year Y. Total fuel consumed per capita for transportation.

 
Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.

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 Multimodal Crossing provides the operational status and pending requests for right-of-way from marine traffic at the drawbridge (multimodal crossing status) to the Traffic Management Subsystem and Roadway equipment.

  2. The Roadway equipment can in turn request an opening of the draw bridge (right-of-way request notification) for a marine vessel.

  3. The Traffic Management Subsystem can configure, download timings and otherwise control (signal control commands) signal equipment along the roadway to control traffic approaching a drawbridge. Traffic Management Subsystem can monitor the status of this equipment (signal control status and signal fault data). Signals can be used to stop vehicular traffic for a draw bridge opening. Additionally, this equipment can supply information on the current status of the traffic control equipment indicating right-of-way availability to marine traffic at the drawbridge (highway control status) to the Multimodal Crossing.

  4. The Traffic Management Subsystem controls (roadway information system data) the equipment such as DMS and HAR on the Roadway that provides information (driver information) including the current status of the drawbridge and time of planned openings to Drivers.

  5. The Traffic Management Subsystem continues asynchronous monitoring (roadway information system status) of this equipment.

  6. The Traffic Management Subsystem can share the current and/or expected status of the drawbridge (road network conditions) with an Information Service Provider.
