There is no such criterion in the Department’s current guidance. PV2 was superseded in 1995 by a decision framework approach in Local Transport Note 1/95, The Assessment of Pedestrian Crossings. The current guidance lists a number of parameters to be considered including the number of vehicles, speed of approach, number of pedestrians, proximity of schools, and stations. Using these in a decision framework enables local authorities to compare alternative solutions and make an objective decision as to whether a crossing is needed and which type is most suitable.
