Modelling traffic flow through urban uncontrolled intersections in developing countries like India is acomplex process because of the high level heterogeneity of traffic and absence of major and minor concepts in trafficregulation schemes. Moreover, Indian codes have not been provided any relation which can be used to directlydetermine the delay at uncontrolled intersections under Indian traffic conditions.Uncontrolled intersections are vital points on urban roads, the performance of which will influence the traffic flowon entire network. Delays to vehicles at urban uncontrolled intersections depend upon the several factors, the mostimportant among these being major road approach volume, type of turning movement, and vehicular composition.The average delay caused to vehicles is an important measure to evaluate the performance of uncontrolledintersections. The performance of an uncontrolled intersection is described by the service delay experienced by lowpriority movements. Under mixed traffic conditions, the traffic compositions, apart from the conflicting traffic volumeand proportion of turning traffic are vital factors influencing the service delay. Most of the earlier studiesconducted on this subject, pertain to homogeneous traffic environment, and only a few studies with limited scopehave been conducted under mixed traffic conditions. In this study, the service delay models have been developed forthree uncontrolled intersections located in the city. These models developed were found to be statistically and logicallysound. The level of service for the uncontrolled intersections taken under the study has been evaluated using theestimated average service delays from the models developed.
