Emissions Data Management Equipment Package

Architecture Geographic Scope

Description:

Assimilation and storage of air quality measures and roadside collected emissions data; distribution for general traveler information or for use in demand management programs.

 

Included in:

TCEQ Monitoring Center

Functional Requirements:

1The center shall collect, analyze, and store vehicle emissions data collected from roadside sensors.
2The center shall collect, analyze, and store wide area pollution data collected from sensors that may the general (wide area) environment.
3The center shall configure and control emissions and air quality sensors located in the field.
4The center shall maintain a database of pollution reference data including acceptable and tolerable emissions and pollution levels for the area served by the center.
5The center shall support an interface with a map update provider, or other appropriate data sources, through which updates of digitized map data can be obtained and used as a background for emissions.
6The center shall establish violation parameters, detect emissions violators, obtain the vehicle registration data from the appropriate State Department of Motor Vehicles (DMV) office, and then provide the capability to send violation information to a law enforcement agency.
7The center shall distribute air quality information to the media, traveler information service providers, and traffic management centers. This information may be used for information to travelers or part of demand management programs.
  

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.
1.6.2TC shall include a Traffic Surveillance function.
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.
1.6.3TC shall include a Device Control function.
1.6.3.2The real-time traffic-adaptive control portion of the Device Control function shall be an area wide control to include several jurisdictions.
1.6.3.2.2The area wide control shall be implemented in a manner that permits the following types of vehicles to have preference over other vehicles being controlled.
1.6.3.2.2(b)HOV.
1.8TRAVEL DEMAND MANAGEMENT
1.8.1TDM shall include a communications function.
1.8.1.4The communications function shall provide the capability to send information and data as needed to implement management and control strategies that respond to changing environments, conditions, and policy needs to include, but not limited to, the following:
1.8.1.4(d)Usage data.
1.8.2TDM shall include a processing function.
1.8.2.2The processing function shall provide capabilities to enhance the ability to implement and enforce the following:
1.8.2.2(a)Federal policies.
1.8.2.2(b)State policies.
1.8.2.2(c)Local policies.
1.9EMISSIONS TESTING AND MITIGATION
1.9.0ITS shall include an Emission Testing and Mitigation (ETAM) Function. The ETAM function will provide state and local governments with the capability to enhance their air quality control strategies. The ETAM will provide both wide area and roadside emissions monitoring. Information gleaned from ETAM will be used by Traffic Demand Management (TDM) in the Traffic Management Center (TMC) to mitigate pollution and may be provided to enforcement agencies to compel offenders to comply with standards.
1.9.1ETAM shall include a Wide Area Pollution Monitoring (WAPM) capability.
1.9.1.1WAPM shall support air quality control strategies by assessing the level of emission of ozone precursors in all sectors of the area.
1.9.1.1.1WAPM shall be capable of detecting the level of emission of ozone precursors with a high degree of accuracy.
1.9.1.1.2WAPM shall be capable of determining those sectors, within its monitored area, whose emissions exceed the emission standard.
1.9.1.1.3WAPM shall be capable of automatic self-calibration.
1.9.1.2WAPM shall be capable of providing air quality statistical data to the TMC.
1.9.1.2.1WAPM shall be capable of providing the air quality data on the monitored values of pollution.
1.9.1.2.2WAPM shall be capable of providing the necessary data on emission standards violators for enforcement of air quality standards.
1.9.2ETAM shall include roadside pollution assessment (RPA) capabilities.
1.9.2.2RPA shall be capable of providing air quality statistical data to the TMC.
1.9.2.2.1RPA shall be capable of providing the air quality data on the monitored values of pollution.
1.9.2.2.3RPA shall be capable of providing the necessary data on violating vehicles for enforcement of air quality standards.
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.
7.1.3.1.7(a)Emission data.
