Traffic congestion on urban road network is a result of increase in vehicular traffic as it is characterized by slow speed, longer trip lengths, and longer delays. Unsignalized intersections are provided for to low volume traffic flow and its performance is used to evaluate urban road networks .Delay is considered as the important parameter and evaluation of unsignalised intersections is achieved through Gap acceptance behavior. Gap acceptance behavior is an important parameter for determination of capacity at unsignalized intersection. This article explicitly presents the overview of estimation of capacity of unsignalised intersection using Indo HCM 2017 for better identification of traffic characteristics. Estimation of critical gap, occupation time and delay are some of the major factors considered for the analysis. Data is collected through video graphic techniques at 2 locations in Hyderabad city. Traffic Parameters like volume, approaching vehicle type, accepted and rejected gaps were extracted. The study has also examined the variables associated with occupancy factor, vehicle type and socio demographic features. It is observed that the capacity of pragathi nagar T intersection is 845vehicles /hour and critical gap is 4.29 seconds and the capacity of bahadurpally (4 legged) Intersection is 647 vehicles / hour and critical gap is 4.02 seconds.

Critical gap, stratified sampling technique, conventional methods, and occupancy factor.
