panda crossing
The panda crossing was a type of signal-controlled pedestrian crossing used in the United Kingdom from 1962 to 1967.
==Background==
In the early 1960s, the British Ministry of Transport, headed by Ernest Marples, was looking for a way to make pedestrian crossings safer under increasingly heavy traffic conditions. The successful zebra crossing design was not considered safe enough for busy roads and could create traffic delays as pedestrians crossed whenever they wanted. Off-the-shelf light-controlled systems were available but were too expensive for widespread use. Some cities had innovated their own one-off crossings but the lack of standardisation was considered a safety issue. Furthermore, all existing signalled crossings tended to have two major drawbacks: stopping traffic for long periods of time and appearing to violate contemporary right-of-way law by signalling "Don't cross" to pedestrians (in reality: the 'Don't Cross' indication was not a legally enforceable instruction).〔(【引用サイトリンク】url=http://www.cbrd.co.uk/histories/pedestriancrossings/4.shtml )〕
The panda crossing was introduced in 1962 as an attempt to combine the best features of available and experimental crossing systems. The first public example was opened on 2 April of that year outside Waterloo Station, London. The majority of the initial sites used for this experiment were in Guildford where all 13 existing crossings were converted, and in Lincoln where 10 crossings were converted. Further sites across England and Wales increased the size of the experiment to more than forty sites in all.
