Phased Installation of Masts and Sensors

• In a first phase, the masts were installed in winter 2013 and sensors (WS200-UMB Smart Weather Sensor, WS300-UMB Smart Weather Sensor, Precipitation Sensor R2S-UMB and others) were installed on the mast and put into operation.
• After the winter, pavement sensors were installed in Stage 2. 

The system includes cloud-based storage. As a temporary solution, SmartView3 (web-based visualization and data software) was used. In future, the data will be integrated in the MDOT MDSS.
