Editing Zebra crossing (section)

A 1998 Swedish study by A Várhelyi at [[Lund University]] investigated driver behavior at zebra crossings: 
{{quote|The frequency of giving way is 5%. Drivers do not observe the law concerning speed behaviour at the zebra crossing, as they do not "adapt the speed in such way that they do not endanger pedestrians who are already on, or are about to step onto the zebra crossing". In encounters, three out of four drivers maintain the same speed or accelerate and only one out of four slows down or brakes. These results indicate that maintained high speed (even exceeding the speed limit of 50 km hour-1) is the signal from the drivers that they do not intend to give way to the pedestrian at the zebra crossing. The conclusion is that encounters between cars and pedestrians at the zebra crossing are critical situations in which the driver has to be influenced before he reaches the decision zone at 50 to 40 m before the zebra crossing in order to prevent the 'signalling by speed' behaviour.<ref>{{Cite journal |pmid = 9805516|year = 1998|last1 = Várhelyi|first1 = A.|title = Drivers' speed behaviour at a zebra crossing: A case study|journal = Accident Analysis and Prevention|volume = 30|issue = 6|pages = 731–43|doi = 10.1016/S0001-4575(98)00026-8}}</ref>}}
