Roadway Environmental Monitoring Equipment Package

Architecture Geographic Scope

Description:

Environmental sensors, surface and sub-surface, that collect weather and road surface information. Weather conditions measured include temperature, wind, humidity, precipitation, and visibility. Sensors measure road surface temperature, moisture, icing, salinity, etc.

 

Included in:

City of Sherman ITS Field Equipment
TxDOT Paris District DMS
TxDOT Paris District HAR
TxDOT Paris District RWIS Sensors

Functional Requirements:

1The field element shall include surface and sub-surface environmental sensors that measure road surface temperature, moisture, icing, salinity, and other measures.
2The field element shall include environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
3The field element's environmental sensors shall be remotely controlled by a maintenance center.
4The field element's environmental sensors shall be remotely controlled by a traffic management center.
5The field element's environmental sensors shall be remotely controlled by weather service providers such as the National Weather Service or value-added sector specific meteorological services.
6The field element's environmental sensors shall be remotely controlled by a maintenance and construction vehicle.
7The field element shall provide environmental sensor equipment operational status to the controlling center or maintenance vehicle.
8The field element shall provide environmental sensor equipment fault indication to the controlling center or maintenance vehicle.
9The field element shall remotely aggregate environmental sensor data with environmental data collected from maintenance and construction vehicles.
10The field element shall provide weather and road surface condition data to centers.
11The field element shall provide weather and road surface condition data to maintenance and construction vehicles.
