The accident data prior to them being installed shows no pedestrian injuries as a result of speed; the issue of speeding, perceived or otherwise will not be solved with speed cushions because the small minority who speed will not slow down for a speed hump, but they will swerve to try and avoid one... (safety audit observations!). So there is no case to require an alternative. There was no greater danger before the speed cushions were installed, there are now safety risks and an increased danger... three pairs of cushions next to laybys and a pair of speed cushions 18m from a pedestrian crossing (which breaches regulations written in law!).
We are being greenwashed (or safetywashed) into believing we need speed mitigation here!
Longer term, a better road design within Marple is certainly required, but the current temporary measures make any problem worse, not better. So leaving them there or forcing the agenda for an alternative before they are removed is misguided in my opinion.
