The I-64 Afton ATSMS includes numerous improvements:
- A network of dynamic message signs to keep drivers informed of changing traffic and weather conditions.
- Additional traffic cameras that will allow complete surveillance of the corridor by the Staunton Traffic Operations Center, which provides real-time information to drivers through the 511 Virginia system.
- Visibility detection sensors to improve the response and performance of the existing fog-light system.
- Fiber-optics infrastructure that will support future development of variable speed limits based on weather and traffic.
This section of the I-64 corridor has a higher than average traffic crash rate related to fog or wind, including several large multivehicle accidents. The ATSMS project helps to mitigate frequency and severity of crashes related to adverse weather conditions within the corridor.
Keeping drivers informed of road and weather conditions is a key component of the ATSMS project. Dynamic message signs will communicate information gathered in the Staunton Traffic Operations Center from the visibility detection sensors, traffic cameras and traffic detection sensors. All of these systems aggregate atmospheric and roadway surface condition information as well as traffic speed and volumes.
The VDOT TOC for the Northwestern Region, located in Staunton, will be responsible for operation and maintenance of the system. Other key stakeholders in the project will include the Virginia State Police, as well as multiple city and county law enforcement and emergency response agencies that respond to incidents occurring along the corridor.
Benefits of Project
By supplementing exiting intelligent transportation system technologies on Afton Mountain TOC operators will have improved traffic incident management and information sharing capabilities. Drivers will have an improved driving and decision making experience to help achieve lower crash rates along this portion of the I-64 corridor, making the road safer for all who use it.
