Pedestrian level of service simulating and redesigning sidewalk in crowded urban areas

摘要

The design of sidewalks in crowded areas is of great importance in cities. These spaces are sensitive if they happento be in a central business district (CBD). In this research study, the main objective is to analyse and design thesidewalk adjacent to the bazaar in Semnan, Iran, in a CBD, positioned in a historical location of the city. Aftersurveying number of pedestrian sidewalks during peak hours in the morning and evening, the above-mentionedstreet was divided into eight parts, and the highest traffic flow was considered as a criterion for the design. Then,based on HCM2016, the density and the level of service (LOS) of each part were obtained. The findings indicated thatpart 4 had LOS E and density 11 < 11, 52 < 18, part 6 had LOS E and density 11 < 12, 06 < 18 and part 7 with thehighest traffic volume of about 2500 people and LOS E was prioritised to increase LOS. The data obtained for eachpart were studied by PathFinder software and compared with the obtained manual information. Therefore, the roaddiettheory was implemented. By increasing the width of the sidewalk by about 3–5 ft/section, there was a resultingimprovement in LOS.
