THE INFLUENCE OF A CLIMBING LANE ON TRAFFIC FLOW

STIGNINGSFAELTETS INVERKAN PAA FRAMKOMLIGHET

This project is a study of differences in the traffic flow between uphill roads with and without climbing lanes. The study has been carried out with a simulation technique, whose realism has been compared with corresponding results from field measurements. The quantities evaluated are travel time, queue size, instantaneous speed and overtaking ratio. Furthermore is the influence of climbing lanes on safety reported. This project, which would form the basis of modified specifications for climbing lanes, points out that the basic criteria for the specifications should be reconsidered and suggests a continued analysis of the climbing lane problems. /TRRL/
