Title:
County-Wide Variable Speed Limits?
Abstract:
In Finland several road sections, totalling approximately 350 km, have been equipped with variable speed limits. The aim of the study was to estimate the costs and the benefits of a weather-controlled variable speed limit system that would cover most of the Finnish main roads. The building costs and annual maintenance costs were evaluated based on a quality, up-to-date system. It seems likely that a weather and road condition controlled system of variable speed limits would be profitable in Finland. The benefit-cost ratio calculated with the most likely starting values was 1.1?1.9. As a conclusion, it can be said that it is probably not advisable to build variable speed limit systems very extensively but more of them should be built on highly trafficked road segments.
