A hole in SERA’s holistic approach

Announcing a proposal to limit speeds on the M1 near Sheffield to 60mph, the Today Programme interviewed Samantha Heath of SERA, an environmental pressure group linked to Labour. Her holistic approach seemed to boil down to lower speeds and fewer cars. As usual, no mention was made of my 2007 proposal, voiced in No Idle Matter and supported by among others, Prashant Kumar of Surrey University, to reform the system and remove the prime obstructions to sociable speeds and efficient filtering, viz. traffic lights.
