Permanent bus based park and ride schemes are most often found in the UK in historical towns and cities where the narrow streets mean traffic congestion hits hardest and streets cannot easily be widened. An example is Oxford, which operated the first scheme in the UK, initially with an experimental service operating part-time from a motel on the A34 in the 1960s, and then on a full-time basis from 1973. Large scale adoption in other towns then continued from the 1980s with increased car ownership. As of 2005 there were 92 park and ride sites across 40 locations in England
