Roadway Equipment Coordination Equipment Package

Architecture Geographic Scope

Description:

This equipment package coordinates field equipment that is distributed along the roadway by supporting communications directly between the field equipment. This includes coordination between remote sensors and field devices (e.g., Dynamic Message Signs) and coordination between the field devices themselves (e.g., coordination between traffic controllers that are controlling adjacent intersections.).

 

Included in:

City of Wichita Falls Field Equipment
Municipal Field Equipment
TxDOT Flood Detection
TxDOT Wichita Falls District CCTV
TxDOT Wichita Falls District DMS
TxDOT Wichita Falls District Field Sensors
TxDOT Wichita Falls District HAR
TxDOT Wichita Falls District Traffic Signals
USGS Field Equipment

Processes:

1.1.1.5Provide Sensor Interface to Other Roadway Devices
1.2.7.8Provide Device Interface to Other Roadway Devices
  

User Service Requirements (fully or partially addressed):

1.0TRAVEL AND TRAFFIC MANAGEMENT
1.2EN-ROUTE DRIVER INFORMATION
1.2.3DI shall provide an In-vehicle Signing capability.
1.2.3.2The DI In-vehicle Signing function shall include a long term capability to serve more of the traveler's needs.
1.2.3.2.3The In-vehicle Signing function shall provide the capability to utilize data from roadside environmental sensors as inputs to warning messages.
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.
1.6.3TC shall include a Device Control function.
1.6.3.3The Device Control function shall provide the capability to exercise control over those devices utilized for traffic control.
1.6.3.3.2Device 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.
1.6.3.4Device Control shall communicate control data to the following devices.
1.6.3.4(b)Ramp meters.
1.6.3.4(c)Information signs.
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.
1.7.1.1.1(b)Environmental sensors.
1.7.1.1.1(g)Sponsors of special events.
1.7.1.2The Incident Identification function shall include the capability to identify existing (both planned and unplanned) incidents.
1.7.1.2.1The Incident Identification function shall use information from the following types of sources, where available, to identify existing incidents:
1.7.1.2.1(b)Environmental sensors.
1.8.2TDM shall include a processing function.
1.8.2.1The processing function shall provide the capability to generate management and control strategies that facilitate the implementation of policies and regulations designed to address the following:
1.8.2.1(e)Air pollution/emission information and detection.
