IMPACT OF LANE WIDTH OF ROAD ON PASSENGER CAR UNIT CAPACITY: A REVIEW

Abstract

Passenger car unit is used to show the outcome of different mixed vehicle types on traffic flow. The study of basic traffic flow features like traffic volume, it is obligatory for the effectual drafting, designing and performance of roadway system. India is a developing country and consisting of heterogeneous traffic in which different dimensional and operational features of vehicle occupying same lane. Different vehicle type occupy different spaces on the road, move at different speeds and start at different speeds. Besides, the behaviour of drivers of different types of vehicle can also differ considerably. The moving vehicles of heterogeneous traffic occupy any convenient lateral position on the road without any lane discipline, based on the availability of space. This study is related to determine the value of PCU values of different vehicles in under mix traffic flow at on congested highways. Passenger Car Unit (PCU) of different types of vehicles are required to convert a mixed traffic stream into a homogeneous equivalent, and thereby to express the mixed traffic flow in terms of equivalent number of passenger cars. In this paper the required data is collected at some highways around Amravati city. Data collected and analyzed the traffic characteristic. Nowadays traffic is increasing rapidly which is responsible for congestion on highway due to which accidents rate is accordingly increases. Our aim is to work out the passenger car unit for different types of vehicles under mixed nature traffic conditions.
