The Roselle Police Department receives complaints regarding speeding autos or excessive amounts of traffic on a regular basis. In order to evaluate and address these concerns, the Department utilizes special equipment.
The first step generally involves accurate evaluation of the extent of the problem, which is accomplished through the use of traffic counters. The counters are small computers embedded in a rubber pad which is attached to the pavement to determine speeds. The results, including the time of day, are recorded. The subsequent report allows the Department to focus speed radar enforcement at specific times at a given location. Additionally, the reports may indicate the absence of a problem, in which case, extra patrols may not be justified at a specific location.
If a problem is found, the second step may involve placement of the S.M.A.R.T. trailer at the location. The S.M.A.R.T. trailer or speed trailer, as it is frequently called, consists of a radar unit attached to a mobile display unit. The unit displays a vehicle's speed as it approaches the trailer. The display will flash when a vehicle's speed exceeds the posted speed limit. Radar enforcement is often conducted in the areas where the speed trailer is placed, both during and after its deployment. You should assume that if the trailer is at a location, that the Department is giving the area extra attention and the likelihood of receiving a citation are great.
