| Abstract: | Congress has provided states with funds to enforce the National Maximum Speed Limit with selective traffic enforcement programs (STEP). A quasi-experimental design was used to examine the differences of speed characteristics by comparing the deployment of one or more patrol units at a given STEP location. To determine the impact of one, two, or three patrol units per STEP location, roadways in Dallas and Ft. Worth, Texas were assigned one of these conditions. Pre and post enforcement radar samples were taken without patrol units at the STEP sites. Citation data, including speeding, hazardous moving, non-hazardous moving, and non-moving violations, were collected from the STEP records maintained by the individual police departments. There were two hypotheses generated from this research. The first hypothesis was concerned with the difference in deploying one, two, or three police patrol units per STEP site on the speed parameters. Four measures were used to evaluate this hypothesis. The second hypothesis was concerned with the number of citations issued at each of the STEP locations. Two measures were used to test this hypothesis. The analysis of variance was utilized to test the following measures: (a) there are no significant differences in the police patrol tactic of using one, two, or three police patrol units per STEP site on mean speed, and (b) there are no significant differences in the police patrol tactic of using one, two, or three police patrol units per STEP site on the total number of traffic citations issued per STEP location. A test of proportion was used to test pre to post differences in the percentage of motorists exceeding 55, 60, and 65 mph on the STEP sites with one, two, or three patrol units. There was no evidence generated from the analysis conducted of the data collected during this study which would support rejection of either of the two hypotheses. |
