Variable Speed Limit System

SmartZone ITS

SmartZone’s Variable Speed Limit System provide speed limit guidance based on travel or weather conditions. Studies show that reducing the speed limit in less than ideal conditions decreases the possibility of accidents, increases safety, and helps manage traffic flow.

How It Works

Data gathered from sensors placed upstream from the targeted area is analyzed, based on the outcome, a safe traveling speed will be determined and displayed on speed limit signs, radar speed trailers or message boards. As traffic flow improves, speed limits can automatically be adjusted

Messaging used in this solution include:

  • Safe speed limit posting

Benefits:

  • Increased driver awareness
  • Improved safety
  • Reduced traffic congestion
  • Fewer accidents
