| Framework for Analyzing Effects of Spring Load Restrictions (2009) | |||||||||||||||
Abstract | |||||||||||||||
| Spring load restrictions (SLR) impose restrictions on heavy trucks during the spring thaw period. Although the policies have been implemented for many years, their economic effects on truckers remain uncertain. This study provides an overview of practices around the world and sets up a framework to estimate the benefit–cost of the SLR policy. A freight demand model in Minnesota was built to estimate the impacts of SLR on the freight transportation pattern. The model allows various policy scenarios to be tested before being put into practice. A preliminary result of the freight demand model indicates the SLR policy increased truck vehicle kilometers of travel in Lyon County, Minnesota, by about 13%. Spring load restrictions (SLR) restrict the axle loading of heavy trucks during the spring thaw. SLR [under various names, including spring (seasonal) weight restrictions, spring bands, or spring thaw load restrictions] are implemented in many countries with cold climates, | |||||||||||||||
