Abstract (2. Language): 
Pedestrians constitute the largest single road user group in Bangladesh. From MAAP Data Base, it is observed that highest frequency of pedestrian casualties in Dhaka city occur at road side and footpath (48%) [1]. Hence pedestrian walking along the roadway in lieu of walkway is a major problem to be concerned for Dhaka city. The study aims at evaluating the current scenarios of major pedestrian walkways in Dhaka city from various category areas to determine whether there are any need to redesign those or not. Eight walkways representing eight category areas of Dhaka had been selected in this regard and level-of-services of those walkways were quantified following Highway Capacity Manual method. Walkways were investigated for two conditions (i.e. existing condition, and considering no obstruction condition) to come to a conclusion about the effectiveness of selected walkways. For simplicity of field observation, only pedestrian unit flow rate (p/min/m) was used as service measure of LOS. Pedestrians walking on both sidewalk and roadside (both directions) were taken into account in the study. From the result it is found that in existing condition, on an A (most comfortable) - F (least comfortable) scale for the walkways surveyed five out of eight are performing in LOS-C, LOS-D and LOS-E which conform to poor condition. Whereas, if there were no obstruction present in these walkways, seven walkways would provide LOS-A and LOS-B which depicts majority of the walkways in Dhaka are adequate in dimension to provide comfortable walking.
