9.4.2: Collect Environmental Data
This process is responsible for gathering environmental and road condition data from sensors, weather sources, and other ITS centers to support the Manage Maintenance and Construction function. The data gathered by this process shall include the outputs of environmental and road condition sensors located at the roadway or on maintenance and construction vehicles. It shall also include environmental probe data collected from ITS-equipped vehicles by short range communications equipment or ITS centers. Data gathered by this process shall include data collected from weather sources, including both the weather service and transportation weather service providers. Data gathered by this process shall include data collected from other maintenance and construction management centers. The process shall be capable of controlling environmental sensors at the roadway or on maintenance and construction vehicles. The process shall send the environmental and road condition data to other Manage Maintenance and Construction processes for display, processing, analysis, storage, and for use in anticipating needed roadway maintenance and treatment activities. The process shall collect and send environmental sensor operational status (state of the sensor device, configuration, and fault data) to other processes for equipment repair, if needed. The process shall also receive quality check information from weather service providers to assist in identifying where environmental sensors are not providing quality data.
