It was unfortunate that the traffic hump debate 'Are speed humps making some roads unsafe' (NCE 14 June) excluded the one-way narrowings, intended, according to the (former) DETR, to slow down traffic. Am I alone in thinking this is a fatuous and inefficient form of 'traffic calming'?
I believe these features are potentially far more dangerous than any road humps, not only because they introduce a new hazard, nor because many of them are at inappropriate locations.
The right of way flow carries on unhindered - even speeding up on occasions to ensure the right of way, while 50% of the traffic is brought to an inefficient, frustrating standstill. Have there been any studies to determine their effectiveness and safety?
Some form of slowing down is essential at times and, as long as drivers need to be persuaded to do so, I much prefer the road hump.
