Roadway Incident Detection Equipment Package

Architecture Geographic Scope

Description:

This Equipment package provides incident detection capability to reside at the roadside. For example, advanced CCTV's with built-in incident detection algorithms would allow the actual detection function to be roadside rather than transmitting images to a center for visual or automated detection.

 

Included in:

TxDOT Atlanta District Environmental Sensors

Processes:

1.1.1.1Process Traffic Sensor Data
  

User Service Requirements (fully or partially addressed):

1.0TRAVEL AND TRAFFIC MANAGEMENT
1.6TRAFFIC CONTROL
1.6.2TC shall include a Traffic Surveillance function.
1.6.2.1Traffic Surveillance shall include a vehicle detection function with the capability of accurately detecting vehicles in a real-time fashion.
1.6.2.1.1Vehicle detection shall include the capability to determine those vehicles that are HOVs.
1.6.2.2Traffic Surveillance shall include a data collect function to provide the capability to collect data for determining traffic flow and prediction.
1.6.2.2.1The data collect function shall provide the capability to quickly feedback traffic data to the control processes.
1.6.2.3Traffic Surveillance shall include a wide-area surveillance capability to include several jurisdictions.
1.6.2.3.1The wide-area surveillance shall gather speed and flow information.
1.6.2.4TC shall provide the capability to acquire detailed traffic measurements at specific locations.
1.7INCIDENT MANAGEMENT
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.
1.8TRAVEL DEMAND MANAGEMENT
1.8.0ITS shall include a Travel Demand Management (TDM) function. Travel Demand Management will generate and communicate management and control strategies that will support and facilitate the implementation of TDM programs, policies and regulations. It consists of two major functions, which are, (1) Increase Efficiency of Transportation System and (2) Provide Wide Variety of Mobility Options.
1.8.3TDM shall include a sensors/control function.
1.8.3.1The sensors/control function shall provide the capability to gather information needed for the generation of management and control strategies to include, but not be limited to the, following:
1.8.3.1(b)Usage levels.
8.0MAINTENANCE AND CONSTRUCTION MANAGEMENT
8.1MAINTENANCE AND CONSTRUCTION OPERATIONS
8.1.3Maintenance and Construction Operations shall provide a Work Zone Management and Safety (WZMS) function, which provides support for the effectiveness, safety, and efficiency of roadway operations during all work zone activities. This function includes interactions among Traffic Managers, Supervisors, Dispatchers, Field Crews, Construction Crews, Public Safety Organizations, Information Service Providers, and Travelers.
8.1.3.1WZMS shall monitor, control, and direct activity in the vicinity of work zones.
8.1.3.1.3WZMS shall be able to divert vehicles around work zones via automated lane changing techniques.
8.1.3.1.3.1WZMS shall collect information used to support automated lane changing, including but not limited to:
8.1.3.1.3.1(a)Volume
8.1.3.1.3.1(b)Occupancy
8.1.3.1.3.1(c)Speed
8.1.3.1.3.1(d)Headways
8.1.3.1.3.1(e)Vehicle characteristics
8.1.3.1.3.1(f)Merging distance
