Queue Warning Systems

26% of all traffic fatalities in work zones occur as a result of end of queue crashes. Queue warning systems are a proven, effective yet inexpensive way to reduce this number. One or more sensors measure traffic speeds. When they drop below a user defined level, software triggers messages on portable changeable message signs upstream of the problem warning drivers to prepare to stop.

Our systems react in seconds. Messages upstream change to warn drivers in a minute or two giving them plenty of time to prepare and that reduces incidents and improves throughput. Our sensors are equipped with both cellular and satellite modems so the data will always get through ensuring dependable warnings and continuous data coverage.
