RESEARCH WAS CONDUCTED TO INVESTIGATE THE GAP ACCEPTANCE OF PEDESTRIANS AT AN UNMARKED MIDBLOCK CROSSING. DATA WERE COLLECTED BY MEANS OF TIME-LAPSE PHOTOGRAPHY AND ANALYZED WITH THE AID OF A PHOTO-OPTICAL DATA ANALYZER. STATISTICAL TESTS, SUCH AS THE KOLMOGOROV-SMIRNOV TEST, THE CHI-SQUARE TEST, AND ANALYSIS OF VARIANCE, WERE UTILIZED TO INVESTIGATE THE RELATIONSHIP BETWEEN SIZE OF GAP ACCEPTED AND VARIOUS FACTORS SUCH AS TIME WAITED AT CURBSIDE, VOLUME OF TRAFFIC, NUMBER OF PERSONS WAITING AT CURBSIDE, SPEED OF APPROACHING VEHICLE, AND WALKING SPEED OF THE PEDESTRIAN. SOME CONCLUSIONS DRAWN FROM THE RESULTS OF THE TESTS ARE THAT FEMALE PEDESTRIANS WERE WILLING TO WAIT LONGER AT CURBSIDE FOR A SUITABLE GAP THAN WERE MALE PEDESTRIANS; MALE PEDESTRIANS ACCEPTED SHORTER GAPS THAN DID FEMALE PEDESTRIANS; THE MINIMUM ACCEPTABLE GAP IN A SINGLE STREAM OF TRAFFIC WAS 3 SEC OR 75 FT; SHORTER GAPS WERE ACCEPTED BY GROUPS OF PEDESTRIANS RATHER THAN BY INDIVIDUALS; AND INDIVIDUAL PEDESTRIANS CROSSED THE ROADWAY AT GREATER WALKING SPEEDS THAN DID GROUPS OF PEDESTRIANS. /AUTHOR/
