TMC Dynamic Lane Management and Shoulder Use Functional Area

Description

'TMC Dynamic Lane Management and Shoulder Use' remotely monitors and controls the system that is used to dynamically manage travel lanes, including temporary use of shoulders as travel lanes. It monitors traffic conditions and demand measured in the field and determines when the lane configuration of the roadway should be changed, when intersections and/or interchanges should be reconfigured, when the shoulders should be used for travel (as a lane), when lanes should be designated for use by special vehicles only, such as buses, high occupancy vehicles (HOVs), vehicles attending a special event, etc. and/or when types of vehicles should be prohibited or restricted from using particular lanes. It controls the field equipment used to manage and control specific lanes and the shoulders. It also can automatically notify the enforcement agency of lane control violations.

Functional Requirements

IDRequirement
01The center shall remotely monitor and control dynamically managed travel lanes.
02The center shall monitor traffic conditions and demand measured per lane.
03The center shall receive input from Border Inspection Systems to identify existing and planned lane configurations at the border.
04The center shall receive input from multimodal crossings such as draw bridges to identify existing and planned lane configurations at the crossings.
05The center shall receive input from an Intermodal Terminal to support monitoring and anticipation of commercial vehicle traffic originating at the depot and requests for dynamic lane management in the vicinity of the depot.
06The center shall monitor and coordinate dynamic lane controls with adjacent jurisdictions.
07Based on the collected data and operator input, the center shall determine suggested and required lane control configuration changes.
08The center shall support temporary use of shoulders as travel lanes.
09The center shall activate lane management field equipment that is used to dynamically manage specific lanes and shoulders.
10The center shall identify lane use restrictions, prohibiting specific types of vehicles (e.g., commercial vehicles) from specific lanes.
11The center shall designate lanes for use by special vehicles only, such as buses, high occupancy vehicles (HOVs), or vehicles attending a special event.
12The center shall receive environmental information from roadway sensors and connected vehicles to identify existing and planned lane configurations long the roadway.
13The center shall optimize lane use restrictions for the environment.
14The center shall reconfigure intersections and interchanges for compatibility with the current lane configuration.
15The center shall notify the enforcement agency of violators of the lane controls.
16The field element shall analyze collected vehicle and sensor emissions data against reference data, and determines whether or not an eco–lane should be created or decommissioned along a roadway.
17The center shall accept requests for dedicated bus lanes from the transit center.
18The center shall notify the transit center of dedicated bus lane status.
