TMC Regional Traffic Control Equipment Package

Architecture Geographic Scope

Description:

Coordination between traffic management centers in order to share traffic information between centers as well as control of traffic management field equipment. This may be used during incidents and special events and during day-to-day operations.

 

Included in:

City of Livingston Traffic Operations Center
City of Lufkin Traffic Operations Center
City of Nacogdoches Traffic Operations Center
LADOTD
Municipal or County Traffic Operations Center
TranStar and Other Texas Region TMCs
TxDOT Lufkin District TMC

Functional Requirements:

1The center shall exchange traffic information with other traffic management centers, includes incident information, congestion data, traffic data, signal timing plans, and real-time signal control information.
2The center shall exchange traffic control information with other traffic management centers, includes remote monitoring and control of traffic management devices (e.g. signs, sensors, signals, cameras, etc.).
  

User Service Requirements (fully or partially addressed):

1.0TRAVEL AND TRAFFIC MANAGEMENT
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.
1.6.1TC shall include a Traffic Flow Optimization function to provide the capability to optimize traffic flow.
1.6.1.7Implementation of the Control function shall include strategies that account for at least the following:
1.6.1.7(a)Human factors.
1.6.2TC shall include a Traffic Surveillance function.
1.6.2.5The wide area surveillance shall acquire sufficient data to provide the system with the knowledge of the existing conditions.
1.6.2.5.2The data process function shall process traffic data to generate near term predictions of traffic conditions.
1.6.3TC shall include a Device Control function.
1.6.3.4(e)Human operator support.
1.6.3.6Device Control shall provide the operator the capability to adaptively change system response in order to provide a response that is coordinated with other TMCs responding to incidents.
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.
5.0EMERGENCY MANAGEMENT
5.1EMERGENCY NOTIFICATION AND PERSONAL SECURITY
5.1.3ENPS shall include a Remote Security and Emergency Monitoring (RSEM) function to create an environment of safety in secure areas.
5.1.3.5RSEM shall include a Physical Security System (PSS) function.
5.1.3.5.2PSS shall allow system operators to monitor and control operation of the physical security system devices, including operator override.
5.1.3.5.3PSS shall provide current status of the system including readiness and activation to operators.
7.0INFORMATION MANAGEMENT
7.1ARCHIVED DATA FUNCTION
7.1.0ITS shall provide an Archived Data Function to control the archiving and distribution of ITS data. The Archived Data User Service provides the Historical Data Archive Repositories and controls the archiving functionality for all ITS data with five major functions: 1) the Operational Data Control function to manage operations data integrity; 2) the Data Import and Verification function to acquire historical data from the Operational Data Control function; 3) the Automatic Data Historical Archive function for permanently archiving the data; 4) the Data Warehouse Distribution function, which integrates the planning, safety, operations, and research communities into ITS and processes data products for these communities; and 5) the ITS Community Interface which provides the ITS common interface to all ITS users for data products specification and retrieval. ADUS helps achieve the ITS information goal of unambiguous interchange and reuse of data and information throughout all functional areas.
7.1.3The Archived Data Function shall include a Data Import and Verification (DIV) function to acquire historical data from the Operational Data Control function.
7.1.3.1DIV shall be capable of importing selected ITS Operational data from the ITS Operational Repositories.
7.1.3.1.9DIV shall be capable of importing data on ITS Physical Characteristics of Transportation Infrastructure to include:
7.1.3.1.9(d)Transportation facilities.
