:: The deal is that they are cheap as chips; all you need is white paint and maybe a couple of Belisha beacons, and they allow pedestrians to cross ( in theory ) safely, without the traffic disruption and construction work that traffic lights would require .

By 1947 the Pedestrians'Association was suggesting that many of the safety features being introduced ( speed limits, traffic calming, road signs and road markings, traffic lights, Belisha beacons, pedestrian crossings, cycle lanes, etc . ) were potentially self-defeating because " every nonrestrictive safety measure, however admirable in itself, is treated by the drivers as an opportunity for more speeding, so that the net amount of danger is increased and the latter state is worse than the first ."
