The report describes three studies of road user behavior which were conducted at zebra and pelican crossings. Pedestrians experienced very little delay or difficulty at zebras on busy roads. This information is of interest in the establishment of warrants. Driver reaction at the particular pelicans which have refuges in the middle of the road and are not staggered was studied. It was found that some drivers erroneously treat the flashing amber period as equivalent to the situation that exists at zebras and only yield to pedestrians crossing on the drivers's side of the road. In twenty two per cent of cases, waiting drivers did not give way and in four per cent of cases, travelling vehicles did not stop. Starting the flashing amber a few seconds later than the flashing green man at a pelican of this configuration is suggested as a solution. The effect on sighted pedestrians of audible buzzer type signals which sound during the green man period was measured. These are normally considered to be of use to blind pedestrians. The audible signal reduced reaction time of sighted pedestrians from 1.79 to 1.36 sec.
