Fuzzy logic was used as a tool for linguistic classification of the premise variable in this model. As far as the simulation results are concerned it was seen that speed value obtained experimentally and obtained from the model are almost same. It was studied that all the three parameters have a significant impact on the speed of a non-motorized vehicle in a mixed traffic. It was seen that speed decreases with increase in number of PCUs in the same strip, speed decreases with increase in number of PCUs in the adjacent strips and speed increase when distance from the road edge increases. Keywords – NMV, MV, PCU, fuzzy logic, mixed traffic. I. INTRODUCTION In Asian countries like India mostly a mixed traffic flow is found. Which means the flow consist of all type of vehicles like cycle, rickshaw, car, bus etc. In Indian cities the share of non-motorized transport (NMT) at peak hours is almost more than 50 per cent. Different cities have different patterns of NMT use. Every public transport mode of transport involves access trips by NMT at each end because never the less at the end at least they need to walk. So, non-motorized mode of traffic plays a vital role in meeting travel demand in countries like India. Importance of non-motorized vehicles in India can be found in Sarana 2010 [11].The study of mixed traffic is quite complicated. In a mixed flow when number of non-motorized vehicles increases of vehicles leads to many problems like conflicts at intersections, it affects the speed and flow of other vehicles. It significantly lowers or reduces the capacity also leads to various safety problems. Therefore a separate track for flow of non- motorized traffic is used in various developed counties like USA, in countries like India this is practically not possible due to lack of space. So in that case a proper study of non-motorized vehicle characteristics should be done along with study of how these NMV are affected in the mixed traffic. Hence study of both NMVs movement and it effect on motorized mode are taken into account in the project. ‘Non-Motorized Vehicles’ (NMVs) is refereed to different types of pedal powered vehicles used in the Indian subcontinent. These include different shapes and sizes of bicycles and tricycles. Tricycles are used to carry goods and passengers; these are commonly called as cycle rickshaws. The various dimensions of NMVs are adopted from Bicycle Infrastructure Design Manual for Indian Subcontinent by Arora 2009 [1]. Various literatures from the past have been studied and few have been considered for this study purpose. Oketch 2003 [5], developed a special model to investigate the effects of various non-conventional vehicles on stream performance including lane capacity and saturation flows. This paper says that for such heterogeneous streams had reduced link capacities and lane saturation flows in comparison to homogenous flows with private cars only, although the trends were not always consistent. Rahman and Nakamura 2005 [10], introduced a method for estimating passenger car equivalents(PCE) for non-motorized vehicle based on speed reduction of passenger cars in the mixed flow due to the presence of non-motorized vehicles from the observed data collected from two mid-block sections of Dhaka, Bangladesh. Similar study was done by Rahman and et al. 2004 [9] to develop an estimation method of passenger car equivalent of rickshaws and auto rickshaws at signalized intersections by a macroscopic approach.Rahman and et al. 2003 [8] also made a study on the effect of non- motorized vehicles on urban road traffic characteristics from four mid-block sections of Dhaka, Bangladesh and concluded that non-motorized vehicles have adverse effect on fundamental traffic parameters. Pan and Kerali 2007 [6] conducted a research on the effects of non-motorized traffic flow on motorized vehicle speeds on the basis of field observations of vehicle speeds on Chinese roads and observed linear relationship between motorized vehicle speeds and non-motorized traffic flow under a range of motorized traffic flow volumes. Dianhai and et al. 2007 [3] made a study on bicycle conversion factor calibration at two-phase intersections in mixed traffic flows from various cities in china. They proposed model to calculate the through bicycle traffic and left-turn bicycle traffic conversion factors in intersections where bicycles and motor vehicles share the same road. Liang and et al. 2011 [12] made a study for calculating straight lane capacity under mixed traffic conditions in China. The First Discharge Headway (FDH) was applied as a novel to improve Stop Line Method
