This paper focuses on the effects of mixed traffic circumstances of uncontrolled or unsignalized intersection under heavy flow when traffic is heterogeneous in character. On the basis of field data collected on Fuljhore road, Durgapur, it is clear that capacity reduces if the proportion of slower vehicles increases in the traffic stream. On the basis of field data collected, the present study also made it evident that the speed data deviate from the normal distribution curve and skewness of speed data is significantly high under the high density of traffic flow. The present study, therefore, examined the distribution of these data and concluded that their logarithmic transformation reasonably satisfies the normality assumption while modeling in terms of goodness-of-fit. Modeling traffic flow through urban uncontrolled intersections in developing countries like India is a complex process because of the high-level heterogeneity of traffic and absence of major and minor road concepts in traffic regulation schemes. Moreover, Indian codes have not been provided any relation which can be used to directly determine the delay at uncontrolled intersections under Indian traffic conditions. Uncontrolled intersections are vital points on urban roads, the performance of which will influence the flow of traffic on the road network.
