A STUDY OF VEHICULAR CONGESTION AND PLATOON DISPERSION BEHAVIOUR AT SELECTED LOCATION OF AHMEDABAD

Abstract

Traffic congestion is one of the major issues that most metropolises cities are facing. As the number of
vehicles is increasing the problem of congestion is also increasing simultaneously. In the present study we have
discussed about platoon dispersion. Platoon of road traffic can be defined as a set of vehicles or pedestrians travelling
together as a group, either freely or compulsorily, because of signal control, road geometry or other factors. Once
released from a signalised stop-line, vehicles normally proceed to the next intersection in bunches. While moving along
a corridor, vehicle platoons disperses and therefore, the pattern of vehicle arrivals at a signal is different from the
pattern of discharge from its upstream signal. 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.
