Abstract: Spring Load Restrictions (SLR) impose
load restrictions on heavy trucks during the spring thaw period. Although
the policies have been implemented for many years, we are still unsure
of their economic effects on truckers. This paper overviews 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 tested in practice.
A preliminary result of the freight demand model shows the SLR policy
increased truck Vehicle Kilometers of Travel (VKT) in Lyon County, Minnesota
by about 13 percent. Key words: Spring load restrictions, Benefit/Cost analysis, EMME/2, Freight demand model |
