Traffic on urban road is heterogeneous when large varieties of vehicles operate in mixed mode condition. The performance of the urban roadway depends on the practical capacity and actual traffic volumes. To estimate the roadway capacity, traffic flow in terms of PCUs and speed of the stream of respective hours were evaluated. The speed flow equation was developed by using PCU volume and the speed. The study reveals that the polynomial form of curve was best fitted for the study area, for upper uncongested segment and linear form for lower congested segment. The capacity obtained was found to be relatively low than the IRC guidelines.
