A proposed definition and method for calculating effective width reductions from pedestrian data is presented. Pedestrian distributions observed in a survey conducted in a pedestrian tunnel at Carleton University, Ottawa, Canada, were used to calculate effective width reductions under various conditions. The reductions calculated for walls ranged between 5.5 in. and 8.7 in. This is less than one-third of the 18 in. suggested by most researchers. Experimentation with obstacles, such as a waste receptacle adjacent to one wall, resulted in even lower effective width reductions. It is concluded that effective width reductions generally assumed in current design practices are overestimated.
