PROGRAMME FOR ROAD INFORMATICS: THEME INFORMATION BEFORE AND DURING THE TRIP: DYNAMIC TRAFFIC INFORMATION FOR THE OELAND BRIDGE

PROGRAM FOER VAEGINFORMATIK: TEMA INFORMATION FOERE OCH UNDER RESAN: DYNAMISK TRAFIKINFORMATION

The object of the project is to improve information for road users on and before the bridge by means of variable message signs. On the basis of road weather information and traffic measurements, road users can be given information regarding headways, queuing, strong side wind, reduced visibility, slippery conditions, cyclists, roadworks etc, and thus road safety and vehicle mobility can be improved and environmental load reduced by means of dynamic traffic information. Follow-up is to be made in terms of mean speed, headway, driving patterns, noise and exhaust emissions. The background is that traffic flow on OEland bridge varies greatly between summer and winter. AADT (average annual dail traffic) is ca 15,200 vehicles. Total of vehicle movements each year is 5.5m. From midsummer until mid-August, traffic is extremely heavy. Traffic volume varies from 29,000 in summer to 8-10,000 in winter. On some days the proportion of cars towing caravans is 8-9 per cent, i.e. over 2500. Compared with other principal routes, the proportion of heavy vehicles is very low and that of caravans extremely high. It is not unusual for caravans to be overturned by strong side winds, causing long delays. Since 1995 the bridge has had four narrow traffic lanes; this has reduced queuing in summer.
