The SMART trailer is far and away one of our most popular tools in the City of Pleasanton. We deploy the trailer on average five days per week in various complaint areas. The trailer uses a standard radar gun to obtain the speed of vehicles displaying the speed next to a speed limit sign, and captures those speeds and the volume of vehicles in an on board computer. The computer generates surveys from which the traffic unit can determine if the speeds of vehicles in the area are exceedingly high or within the limits of the posted speed. To request the trailer call (925) 931-KARS (5277).
