Junction between A556 and Daleford’s Lane Sandiway.
The time on orange after green is set by the Department for Transport. It has a fixed value of three seconds.
At 40 mph you have a point of no return of 30 metres compared with 23 metres at 30 mph. (Highway Code p45)
If this junction gets much more busy the only safe option is to impose a 30mph speed limit, slowing flow on a busy road.
There is a camera on the westward heading junction you have one second decision window at 40 mph as to whether you are past the point when you can stop safely in less than 2 seconds
