A Review : Impact of Road Side Friction on Capacity of Urban Roads

Abstract

Traffic congestion and capacity reduction in urban roads are very common in developing countries like India. Capacity is important fundamental to planning, design and operation of the roads. It is helpful for determination of a number of lanes required by considering a volume of the vehicles, their composition and other traffic-related parameters. Behind capacity reduction in the urban road, there are several reasons that affect the capacity factor such as on-street parking, pedestrian movement, the presence of street hawkers, roadside bus stop. This review paper is intended to highlight various studies reported with regards to the impact of side frictions in a capacity of urban road and gives a suitable measure.
