Title: Utilizing Weigh-In-Motion for Integrated Average Speed and Weight Enforcement (Poster)
Abstract: Vehicle safety is a very important issue in North America. This study looks at alternative uses to current transportation technologies. Numerous engineering safety countermeasures are deployed in order to reduce the number and severity of collisions on the road. Speed limits are one example of a traditional method of imposing safety restrictions on the travelling speed of vehicles. Differential speed limits are when different vehicles have a different maximum speed limit imposed on them depending on some established criteria like vehicle classification or gross vehicle weight. Differential speed limits based on gross vehicle weight are difficult to enforce, as current technology capable of effectively and automatically doing this is not being utilized. Weigh-In-Motion, or WIM, are systems designed to capture and record axle weights and gross vehicle weights as vehicles drive over a measurement site. Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a stop. This makes the weighing process more efficient, and, in the case of commercial vehicles, allows for trucks under the weight limit to bypass static scales or inspection. This study examines a collection of WIM data collected from two different locations in British Columbia, Canada, and examines the statistical relationships between a vehicle’s speed, classification, and gross vehicle weight (GVW). Data comes from the WIM stations outside of Laidlaw and Golden, spaced 560 km apart located on the TransCanada Highway. Data comes from the year of 2014, and the associated weather data has been obtained from Environment Canada.
