Caltrans RWIS

Status: Existing

Description

Road Weather Information Systems are owned by the state with sensors throughout the State of California that measure temperature, humidity and wind speed. Some RWIS stations have pavement sensors, either active or passive. Each District has access to the RWIS server. The system gathers the information and users must log into the system to view the pictures or weather surface information. This element is both existing and planned for expansion.
