This study examined the behaviour of cyclists and other road users at 12 signalled junctions with Advanced Stop Line (ASL) facilities and 2 control sites in London. Video observation over 2 days at each site provided information on 6,041 cyclists. At ASL sites, a larger proportion of cyclists (92%) were able to gain access to the front of traffic queues when stopped at traffic signals than at control sites (64%). At the same time the proportion of vehicles that encroached onto pedestrian crossings while waiting at signals was reduced. However, motorised vehicles encroached onto ASL reservoirs and feeder lanes, reducing their effectiveness. Casualty and conflict analysis could not conclusively determine the safety effect of ASLs. Further research in this and other areas is recommended. (Author/publisher)
