Passenger Vehicle Effect on the Truck Weight Calculations using B-WIM System
Conference: Publication Date: 26 March 2018
Bridge Weigh-in-Motion (BWIM) is the technology of using the bridge as a weigh scales to find the weights of passing trucks. Weight calculations should have a high level of accuracy to enable the B-WIM system from being a tool for direct overload enforcement. This paper focuses on improving the accuracy of the B-WIM system when a passenger vehicle travels over the bridge side by side with the target truck. A solution has been suggested to remove this effect by considering measurements on girders under the truck lane only and exclude the ones under the passenger vehicle lane. Since using the measurements under the vehicle lane will reduce measurements number and thus affect results accuracy, an approximate method are developed to deal with the lower number of measurements. The method has been discussed analytically and experimentally.
