Abstract

Alternatives that may reduce recurrent congestion on recreational routes are considered. Diversion strategies are a low cost strategy for reducing such congestion. Studies have shown that motorists may be willing to use alternate routes and/or alter their departure times. Traffic surveillance systems are necessary to provide the input for diversion decision making. Timely and accurate driver information systems are also necessary. The results of surveys to determine the willingness of motorists are discussed. It was found that while time diversion strategies have not been adequately tested, route diversion systems have been effective in reducing recreational traffic congestion. If the location of bottlenecks are known, patrol vehicles can provide adequate surveillance for diversion strategies. Variable message signs can provide en-route information. Commercial radio used with a predictive method such as time-series analysis that forecasts traffic conditions at bottlenecks can provide pre-trip information to promote time diversion. Impacts of such diversion also briefly discussed.
