Eastbound cyclists wishing to avoid the double roundabout at this point are routed onto the pavement, across the exit for the Shell garage (often to the surprise of exiting drivers), and then (still across pavement) onto a piece of decommissioned road used as access and double-sided parking for a parade of shops. This road has a separate car entrance from the roundabout.
Its a lethal combination -I have personally once been hit by a car turning fast from the roundabout on the road entrance as I entered it from the bike route. The driver was very angry because it was my fault that she didn't look out for me. You then have to cycle between two sets of parked cars/vans: there are frequent hazards: suddenly opened doors, people reversing/leaving the parking place without looking behind.
At the end, the cyclist is signed again onto pavement heavily used by schoolchildren/old people at the eastbound Heath Road Roundabout bus stop, before being routed back onto the road along the pull-off for the bus itself.
My personal view is that this scheme has been created and signed by a maniac
