SOME TENTATIVE FINDINGS ABOUT THE EFFECT OF LEVEL OF ENFORCEMENT ON COMPLIANCE WITH TRUCK WEIGHT REGULATIONS

Almost all highway agencies enforce truck axle and gross weight limits by inspections at permanent weight scales and by mobile patrol units. This paper presents the context, methodology and tentative results of three studies of the effect on compliance carried out on provincial highways in Saskatchewan. Analysis of data from 12 permanent weight scales situated on primary highways indicated that as the inspection rate (apprehension probability) increased to about five percent, the violation rate decreased rapidly. Increasing apprehension probability beyond five percent had little impact on the violation rate. The data from 18 mobile patrol units confirmed this trend. Data from before and after studies at two specific locations were used to study the effect of continuous and/or zero enforcement, in both long-haul and short-haul scenarios. The long haul study showed that the rate of violation of gross weight limits decreased to a low of 2.8% at continous enforcement from 5.6% at normal enforcement. The violation rate increased to 18.6% at zero enforcement. The short haul study also indicated a significant difference between zero and normal enforcement.
