ESTIMATION OF PASSENGER CAR UNIT AT URBAN INTERSECTION USING PLATOON DISPERSION MODEL

Abstract

Passenger car units or passenger car comparisons (PCUs) play a crucial role in the study of the traffic
flow of different types of vehicles in the traffic flow and are used to transform traffic flows of different vehicle types
into traffic flows consisting solely of passenger cars and which have been developed to analyse the effect of different
types of vehicles on the road. In the present study we have discussed about platoon dispersion. Modelling of dispersion
of vehicle platoon is an important consideration for coordinated operation of closely spaced traffic signals. This
analysis is based on video photographic data collected at signalized intersection. The study of platoon dispersion is to a
certain extent associated to driver manners and car following is one key component of driver behaviour. In this study,
field investigation is made by means of videotapes which record traffic flows at several locations. After collection of
video data extraction by any platoon dispersion software. This is used to accurate data collection from any
intersections. Two-wheelers (2W) establish a most important proportion of urban traffic and consequently their
consequence on the saturation flow could be significant. Passenger car unit is an important factor which is used to
convert traffic volumes containing proportions of heavy good vehicles (HGVs) to a unify measure containing only
passenger cars units (PCU).
