The A56 bus corridor (North of England – Trafford) is a key commuter route between the heavily populated town of Altrincham and the City of Manchester. Along the A56 0.5km North of the M60 the Stretford Gyratory system splits an existing bus corridor which ends 200m before the gyratory and re-starts around it’s north side, missing out the gyratory system itself. The gyratory is home to several sets of traffic signals, surface treatment and pedestrian facilities in the form of crossings and cycle lanes. The missing section of Bus corridor is causing busses to sit in the Heavy peak flow traffic for extended periods. The D.f.t. annual average daily flow for the A56 is 35,000 vehicles so is heavily used by commuters.
A connecting bus corridor is required to join up and complete the route through the gyratory system and complete the bus lane.
The solution was to create a Pass-Through Bus Lane allowing busses to effectively miss-out the whole gyratory and pass through it by additional re-timing the existing traffic signals. Minimal construction work is required, and the results would be an increase in bus drop off times and pedestrian service capacity by stopping the busses getting trapped around the junction and moving more freely through the gyratory and back along the A56.
The right-hand turns were tested using AutoTURN and the kerbs were designed around this with some allowance for access in case of a bus breakdown. The Road markings were then designed in Line Design Pro Uk.
