Speed Measuring Devices

How They WorkRadar Trailer
Our radar trailer was purchased by way of grant money from the Governor's Highway Safety Program. It was purchased in April of 2003. It is manufactured by MPH Industries Inc. It has a directional sensing radar unit on board which only displays the speeds of vehicles that are moving toward the trailer. The display is 25" and flashes when a car is traveling five mph or more over the posted speed limit. It is also equipped with amber strobe lights on the side that activate when a vehicle is traveling 10 mph or more over the posted limit.
Radar Trailer
There is an additional onboard computer that collects data from the trailer. This data can tell us the highest, lowest, and median speeds that are measured during a trailer deployment. It is also capable of telling us which types of vehicles are traveling that particular roadway i.e.: passenger cars, pickups, tractor trailers, and so on. We use this information to plan our enforcement activities and to inform the public on the results when they request the trailer.

  awareness devices in various locations around Town.   Collectively we use these  
  valuable resources to clear complaints, increase public awareness, and to simply  
  broaden our impact leads.
