Abstract

Pedestrian speed-flow relationships for central business district (CBD) areas in developing countries were developed. Data were collected from Irbid, Jordan, which is considered a city typical of those in developing countries. In the analysis, pedestrian flows were analyzed on the basis of effective sidewalk width rather than the lane concept.

RESULTS indicate that the capacity of bidirectional CBD sidewalks was 18.22 pedestrians/min/ft (3,590 pedestrians/hr/m). On the basis of this result, the capacity value specified in the 1985 Highway Capacity Manual is not applicable to developing countries even if a reduction factor is applied to consider the bidirectional effect. In addition, the results indicate that a considerable percentage of pedestrians walk along streets beside sidewalks. Therefore, in the design of CBD sidewalks, it is recommended that the pedestrian demand to capacity ratio be limited to 0.5.
