Speed Based Capacity Model for Urban Arterial Roads

Depending on frontage access, signal density and free flow speed (FFS), urban roads are classified into different categories such as arterial and sub-arterial or Class I and Class II. The article shows that within the same category of arterials, capacity of an urban road may be different depending on operating speed. Data collected on four different Indian city urban arterial roads are analyzed and speed-flow diagrams are drawn to estimate capacity and these capacity values are found to be quite different in each city because of operating speed. The model presented in this article gives a quick estimation of capacity of an urban road without collecting field data in the entire range of speed and volume, which can be quite time consuming and expensive.
