Roadway Basic Surveillance Equipment Package

Architecture Geographic Scope

Description:

This Equipment package provides the capabilities to monitor traffic flow in major intersections and on main highways for urban areas and to monitor road conditions using fixed equipment such as loop detectors and wireline communication.

 

Included in:

City of Longview Field Equipment
City of Tyler Field Equipment
TxDOT Tyler District CCTV
TxDOT Tyler District Field Sensors

Processes:

1.1.1.1Process Traffic Sensor Data
1.3.1.3Process Traffic Images
  

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.
1.7.1.2The Incident Identification function shall include the capability to identify existing (both planned and unplanned) incidents.
