This report is part of ongoing research at TRL on innovative cycle scheme commissioned by the Department of Transport. An Advanced Stop Line (ASL) is a cycling facility which allows cyclists to stop ahead of motor vehicles at signalised junctions. It includes a cycle lane approach to the junction which is most commonly located on the nearside. As a response to the increase in the number and type of ASLs installed in the UK, some characteristics of ASL junctions are examined. Video film was taken at 6 ASL sites at Portsmouth (2 ASL arms at this site treated independently), Manchester, Chelmsford, Cambridge and Bristol. The two main aims are to investigate the value of a non nearside approach lane and to assess the effect of different signal timings on the value of an advanced stop line. These are explored with reference to the differing turning movements of cyclists and motor vehicle at ASL junctions. (A)
