TMC Reversible Lane Management Equipment Package

Architecture Geographic Scope

Description:

This Equipment package provides the capability for access and management of reversible lane facilities, including the direction of traffic flow changes during the day, especially between the peak hours and dedication of more lanes to the congestion direction during special events.

 

Included in:

City of College Station Traffic Operations Center
TTI TransLink
TxDOT Bryan District Office

Processes:

1.1.2.7Monitor Reversible Lanes
1.2.4.2Output Control Data for Freeways
1.3.4.2Provide Traffic Operations Personnel Incident Data Interface
5.4.1Process TM Detected Violations
  

User Service Requirements (fully or partially addressed):

1.0TRAVEL AND TRAFFIC MANAGEMENT
1.5.2TSI shall include an Information Access function that allows travelers to access the available information.
1.5.2.5Information Access shall provide the capability for travelers to access the TSI information via any of, but not limited to, the following methods:
1.5.2.5(a)Highway advisory radio.
1.6TRAFFIC CONTROL
1.6.0ITS shall include a Traffic Control (TC) function. Traffic Control provides the capability to efficiently manage the movement of traffic on streets and highways. Four functions are provided, which are, (1) Traffic Flow Optimization, (2) Traffic Surveillance, (3) Control, and (4) Provide Information. This will also include control of network signal systems with eventual integration of freeway control.
1.6.1.2.1Wide area optimization shall integrate the control of network signal systems with the control of freeways.
1.6.1.4Traffic Flow Optimization shall include a Control function that is responsive to both the current demand as well as the expected demand.
1.6.2TC shall include a Traffic Surveillance function.
1.6.2.4TC shall provide the capability to acquire detailed traffic measurements at specific locations.
1.6.2.4.1Traffic Surveillance shall include a data process function to process the traffic data which are acquired.
1.6.3TC shall include a Device Control function.
1.6.3.2The real-time traffic-adaptive control portion of the Device Control function shall be an area wide control to include several jurisdictions.
1.6.3.2.2The area wide control shall be implemented in a manner that permits the following types of vehicles to have preference over other vehicles being controlled.
1.6.3.2.2(b)HOV.
1.6.3.3The Device Control function shall provide the capability to exercise control over those devices utilized for traffic control.
1.6.3.3.1Device Control shall include the capability to control traffic signalization, including rapid modification of signalization parameters to respond to traffic requirements.
1.6.3.3.2Device Control shall include the capability to dynamically control traffic signing.
1.6.3.3.3Device Control shall include the capability to control freeway ramp metering.
1.6.3.3.4Device Control shall include the capability to exercise dynamic control over the infrastructure (such as reversible-lanes, turning restrictions, etc.).
1.6.3.4Device Control shall communicate control data to the following devices.
1.6.3.4.1Traffic Surveillance shall include a data process function to process the traffic data which are acquired.
1.7INCIDENT MANAGEMENT
1.7.0ITS shall include an Incident Management (IM) function. Incident Management will identify incidents, formulate response actions, and support initiation and ongoing coordination of those response actions. Four major functions are provided, which are, (1) Incidents Identification, (2) Response Formulation, (3) Response Implementation, and (4) Predict Hazardous Conditions.
1.7.1Incident Management shall provide an Incident Identification function to identify incidents.
1.7.1.1The Incident Identification function shall include the capability to identify predicted incidents.
1.7.1.1.1The Incident Identification function shall use information from the following types of sources, where available, to identify predicted incidents:
1.7.1.1.1(a)Traffic flow sensors.
1.7.2IM shall provide a Response Formulation function to formulate appropriate response actions to each identified incident and revise those actions when necessary.
1.7.2.1The Response Formulation function shall propose and facilitate the appropriate scheduling of those predicted incidents that can be scheduled to minimize incident potential, incident impacts, and/or the resources required for incident management.
1.7.3IM shall include a Response Implementation function to provide the services to implement a response coordinated with all appropriate agencies.
1.7.3.2The Response Implementation function shall provide a link between Incident Management and all other user services necessary to implement incident response actions.
1.7.4IM shall provide the capability to Predict Hazardous Conditions, including the time and location of hazardous conditions that may cause an incident.
