MC03-Road Weather Data Collection (Service Package*)

Description

This service package collects current road and weather conditions using data collected from environmental sensors deployed on and about the roadway (or guideway in the case of transit related rail systems). In addition to fixed sensor stations at the roadside, sensing of the roadway environment can also occur from sensor systems located on Maintenance and Construction Vehicles. The collected environmental data is used by the Weather Information Processing and Distribution service package to process the information and make decisions on operations. The collected environmental data may be aggregated, combined with data attributes and sent to meteorological systems for data qualification and further data consolidation. The service package may also request and receive qualified data sets from meteorological systems.

Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.

Transaction Set Diagram

Note that this transaction set diagram (TSD) is only 1 of the 3 TSDs and so only a portion of the numbered items below refer to the TSD.

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.

  1. The Maintenance and Construction Management Subsystem (MCMS) can control (environmental sensors control) and monitor (environmental sensor data) road and weather condition sensors at the Roadway. The (environmental conditions) architecture flow represents the road conditions that are measured by an environmental sensor at the Roadway. The MCMS may pass environmental conditions data along to the Weather Service or Surface Transportation Weather Service. The Weather Service is used to represent the Clarus System, which performs quality checks on the sensor data received, formats and consolidates data from multiple sources, and then can send it back to the MCMS as qualified environmental conditions data. The Weather Service can also provide back to the MCMS information on the data quality of the sensor information provided by the center (environmental conditions data status).

  2. Within the MCMS the above process is under the asynchronous monitoring (maint and constr operations information presentation) and control (maint and constr center personnel inputs) of Maintenance and Construction Center Personnel.

  3. The Traffic Management Subsystem (TMS) can also control (environmental sensors control) and monitor (environmental sensor data) road and weather condition sensors at the Roadway. The TMS may pass environmental conditions data along to the Weather Service or Surface Transportation Weather Service, or share it bidirectionally with the MCMS. The Weather Service is used to represent the Clarus System, which performs quality checks on the sensor data received, formats and consolidates data from multiple sources, and then can send it back to the MCMS as qualified environmental conditions data. The Weather Service can also provide back to the MCMS information on the data quality of the sensor information provided by the center (environmental conditions data status).

  4. In some cases the Weather Service is the entity that manages these environmental sensors. In this case the Weather Service would control (environmental sensors control) and monitor (environmental sensor data) the road and weather condition sensors at the Roadway. When the Weather Service terminator is used to represent the Clarus System, it can provide qualified environmental conditions data to the MCMS, TMS, and the Information Service Provider (ISP).

  5. In other cases the Surface Transportation Weather Service is the entity managing the environmental sensors. In this case the Surface Transportation Weather Service would control (environmental sensors control) and monitor (environmental sensor data) the road and weather condition sensors at the Roadway. The Surface Transportation Weather Service may then pass this (environmental conditions data) along either to the MCMS or the TMS (or both).

  6. This data collection alternative covers the case where the environmental sensors are on-board the Maintenance and Construction Vehicle Subsystem (MCVS). The (environmental conditions) architecture flow represents the road conditions that are measured by an environmental sensor on the vehicle. The on-board sensor can be managed by the MCMS. In this case the MCMS controls (environmental sensors control) and monitors (environmental sensor data) the road and weather condition sensors on board the vehicle. Alternately the control could originate with the Maintenance and Construction Field Personnel on-board the vehicle (maint and constr field personnel inputs) and the sensor data would be presented to them (maint and constr field personnel information presentation). Note the control by Field Personnel is not explicitly shown in the diagram, but would certainly be an option.

  7. This data collection alternative involves control (environmental sensors control) and monitoring (environmental sensor data) of sensors at the Roadway from the MCVS. The control begins with the Maintenance and Construction Field Personnel on-board the vehicle (maint and constr field personnel inputs) and passes from the MCVS to the Roadway (environmental sensors control). The sensor data is monitored by the MCVS (environmental sensor data), who could then send it along to the MCMS as described in item 6 above. In addition, the data from on-board sensors can be sent via a wireless link to devices that are part of the Roadway Subsystem for aggregation with other field or vehicle based sensors. This interface between the Roadway and MCVS sensors systems can also be used to support calibration of one system by the other.
