EVALUATION OF A QUEUE WARNING SYSTEM

KOEVARNINGSSYSTEM. UTVAERDERING

In this project a queue warning system in a tunnel with a short visibility distance has been evaluated. The warning is displayed on signs at the entrance of the tunnel. When queue detectors at the exit of the tunnel are occupied, the warning signs are lit. The ramp in the central part of Stockholm, where the warning system has been installed, has achieved very high traffic security. Analyses show that the warning system paid for itself during the first year. (Author/TRRL)
