TxDOT Statewide Highway Conditions Reporting System
TxDOT Yoakum District Office -Traffic

Functional Requirements:

1The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
2The center shall remotely control driver information systems that communicate directly from a center to the vehicle radio (such as Highway Advisory Radios) for dissemination of traffic and other information to drivers.
3The center shall collect operational status for the driver information systems equipment (DMS, HAR, etc.).
4The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.
5The center shall retrieve locally stored traffic information, including current and forecasted traffic information, road and weather conditions, traffic incident information, information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements), etc.
6The center shall distribute traffic data to maintenance and construction centers, transit centers, emergency management centers, and traveler information providers.
7The center shall distribute traffic data to the media upon request; the capability to provide the information in both data stream and graphical display shall be supported.
8The center shall provide the capability for center personnel to control the nature of the data that is available to non-traffic operations centers and the media.

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.
1.7.1Incident 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(d)Media sources.
1.7.3IM shall include a Response Implementation function to provide the services to implement a response coordinated with all appropriate agencies.
1.7.3.3The Response Implementation function shall provide the capability to disseminate information relating to response status to other agencies and user services.
