ATMS18-Reversible Lane Management (Service Package*)

Description

This service package provides for the management of reversible lane facilities. In addition to standard surveillance capabilities, this service package includes sensory functions that detect wrong-way vehicles and other special surveillance capabilities that mitigate safety hazards associated with reversible lanes. The package includes the field equipment, physical lane access controls, and associated control electronics that manage and control these special lanes. This service package also includes the equipment used to electronically reconfigure intersections and manage right-of-way to address dynamic demand changes and special events.

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.

To obtain information about traffic in reversible lanes, the Traffic Management Subsystem can control (traffic sensor control) and monitor (traffic flow) sensors in or along the roadway. It also monitors (signal control status and signal fault data) and controls (signal control commands, signal control device configuration, signal control plans, and signal system configuration) traffic on surface streets and freeways using equipment on the Roadway. The equipment includes signals, automated signs, message signs, etc. that are used to direct traffic on roadways with reversible lanes. The Traffic Management Subsystem also monitors the current reversible lane status and the operational status of the reversible lane control equipment (reversible lane status). The TMS controls (reversible lane control) equipment including sensory functions that detect wrong-way vehicles and other special surveillance capabilities that mitigate safety hazards associated with reversible lanes. This equipment on the Roadway can be coordinated (roadway equipment coordination) with other equipment such as traffic signals, ramp meters, DMS, etc. through peer-to-peer, master-slave or other configurations.
The entire process is under the asynchronous monitoring (traffic operator data) and control (traffic operator inputs) of Traffic Operations Personnel.
