In countries like India we generally find a mixed traffic, i.e. a traffic flow constituting of all types of vehicles like cycle, rickshaw, car, bus, etc. In Indian cities the share of nonmotorized transport (NMT) at peak hours is too high, almost more than 50%. Thus, nonmotorized mode of traffic plays a very important role in meeting travel demand in countries like India. To design a traffic facility it is necessary to understand the behavior of traffic stream. But understanding the behavior of a traffic stream with mixed traffic is quite complex. In this paper an attempt is made to study the non-motorized vehicle characteristics and its effect on mixed traffic. An experimental study is done to observe the fundamental diagram from the data obtained from various roads of Rourkela city in Odisha. It is seen that with increase in NMV % the flow versus density graph is adversely affected. Density decreases at a particular flow rate when NMV % increases. Along with this a study on pattern of lateral occupancy of NMVs and MVs is done with respect to various percentages of NMV and total density. Also the variation of speed with respect to various parameters is studied and it was seen that all the parameters have a significant impact on the speed of a non-motorized vehicle in a mixed traffic.
