Travel or Delay Time Systems
Travel time systems report travel time from a sign to a popular destination such as “downtown” or the airport. Delay time systems report the expected average delay from that sign to a known destination, usually a popular interchange or cross road. Travel time is better for through traffic unfamiliar with the area. Delay time is better for local commuter traffic who can use it to evaluate other possible routes. Sensors collect speeds at various locations and use those to make the calculation which is then reported on message signs, websites, and through social media.
There are many different types of travel and delay systems on the market today. Road-Tech understands the unique requirements in work zones and how to best meet your goals on each job. Technologies that work in permanent locations don’t always work as well (or at all) in work zones. Ask us for our recommendations before you make a final decision.
