RAILWAY SIGNALLING TECHNIQUES USED IN TRAFFIC MANAGEMENT SCHEMES IN STOCKHOLM

JAERNVAEGS- OCH SIGNALTEKNIK I ANVAENDNING VID TRAFIKSANERINGAR I STOCKHOLM

Traffic management schemes usually involve prohibition of through traffic on certain roads. Although this is mostly obeyed, infringement often occurs especially if this results in large savings in time and there is little risk of being caught. Owing to undermanning, the Stockholm Police has little time for surveillance, and for this reason physical barriers are being introduced. The first type is a gate similar to that used at railway crossings. This is actuated by induction set up in a loop installed in the carriageway. The loop can only be actuated by a bus which has a large iron mass situated at a low level, or by a vehicle of similar construction. The gate closes when the bus has passed a detector. The second type of barrier is installed where through traffic is only likely to use prohibited roads during rush hours. This barrier is time controlled and closes the local road between 0700 and 0900 hours on weekdays. The barrier is accompanied by a reversible road sign which is actuated at the same time as the barrier; as warning lights similar to railway crossing lights come on prior to closure of the barrier, this sign is not strictly necessary. /TRRL/
