Included in:

City of Sherman Traffic Operations Center
TxDOT Paris District TMC

Functional Requirements:

1The center shall collect probe data including traffic and road conditions from vehicles via roadside beacon field elements; the data may be aggregated and initial link time calculations performed in the field.
2The center shall collect road condition data from probe-equipped transit vehicles via transit management centers; the data may be aggregated and preliminarily processed at the sending center.
3The center shall collect traffic data from probe-equipped emergency vehicles via emergency management centers; the data may be aggregated and initial link time calculations performed at the sending center.
4The center shall collect traffic data from traveler information centers based on data from their subscriber vehicles; the data may be aggregated and initial link time calculations performed at the sending center.
5The center shall collect traffic data from toll administrative centers containing journey times between toll collection points for those vehicles equipped for electronic toll collection; the data may be aggregated and processed at the sending center.
6The center shall assimilate current and forecast traffic and road conditions based on collected probe data and distribute to other centers for dissemination to travelers.
7The center shall collect operational status for the roadside probe data collection equipment.
8The center shall collect fault data for the roadside probe data collection equipment for repair.
  

User Service Requirements (fully or partially addressed):

1.0TRAVEL AND TRAFFIC MANAGEMENT

This will also include control of network signal systems with eventual integration of freeway control.
1.6.2TC shall include a Traffic Surveillance function.
1.6.2.2Traffic Surveillance shall include a data collect function to provide the capability to collect data for determining traffic flow and prediction.
1.6.2.4TC 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.
1.6.2.5The wide area surveillance shall acquire sufficient data to provide the system with the knowledge of the existing conditions.
1.6.2.5.1The data process function shall combine and process traffic data from multiple sources and times in order to improve the accuracy of the view of the current traffic condition.
1.6.3TC shall include a Device Control function.
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.
1.6.4Device Control shall provide traffic control information to other elements of the ITS, including but not limited to the following:
1.6.4(a)In-vehicle navigation.
1.6.4(b)Trip planning.
1.6.4(c)Routing systems.
1.6.4(d)Fleet management systems.
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.
1.7.4IM shall provide the capability to Predict Hazardous Conditions, including the time and location of hazardous conditions that may cause an incident.
1.8TRAVEL DEMAND MANAGEMENT
1.8.1TDM shall include a communications function.
1.8.1.6The communications function shall include the capability for two-way communications with other ITS user services including, but not limited to, the following:
1.8.1.6(f)Traffic Control.
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(b)HOV lanes and ramps.
1.8.2.10The processing function's dynamically generated management and control strategies shall include the parking management and controls to include, but not be limited to, the following:
1.8.2.10(c)Variable message signs.
5.0EMERGENCY MANAGEMENT
5.3DISASTER RESPONSE AND EVACUATION
5.3.0ITS shall provide a Disaster Response and Evacuation (DRE) function that provides for effective, coordinated management of the surface transportation system during all types of disasters including natural disasters (hurricanes, earthquakes, floods, severe winter storms, tsunamis, etc.), terrorist acts, and other catastrophic events (e.g., nuclear power plant disasters). Two primary subservices are provided: (1) Disaster Response and (2) Evacuation Coordination. The Disaster Response Subservice provides support for planning, transportation management, resource sharing, and information coordination between transportation agencies and principal responding agencies (emergency management, public safety, and other allied agencies) to improve the effectiveness and safety of a disaster response. The Disaster Response Subservice consists of eight major functions: 1) Coordinate Response Plans, 2) Monitor Alert Levels, 3) Detect and Verify Emergency, 4) Assess Infrastructure Status, 5) Coordinate Response, 6) Critical Service Restoration, 7) Manage Area Transportation, and 8) Disaster Traveler Information. The Evacuation Coordination (EC) Subservice efficiently manages an evacuation and provides evacuees with the information they need during evacuation and subsequent reentry to the evacuated area. The Evacuation Coordination (EC) subservice includes four additional major functions: 9) Evacuation Planning Support, 10) Evacuation Traveler Information, 11) Evacuation Transportation Management, and 12) Evacuation Resource Sharing.
5.3.2Disaster Response shall provide a Monitor Alert Levels (MAL) function.
