Time Zone Impact for Traffic Flow Analysis of Ahmedabad City in India

Abstract

This paper describes time zone impact for traffic flow analysis in an one of major city in India based on one month real traffic monitoring big data. The target city is Ahmedabad of Gujarat state where is located in the west part of India. The current population in Ahmedabad is about 7.8 Million and it is one of rapid economic growing city. These days, the traffic congestion in the city become one of major issues. In order to analyse traffic congestion, large amount of the traffic big data is needed and it is collected through the traffic monitoring camera. The measurement of the data is traffic density, traffic occupancy and average of speed of vehicles which is measured at the road by every minute. The traffic data in emerging countries is not well analyzed so far because of difficulty of collecting traffic data. Author has a chance to involve one of traffic project which provides traffic condition to the drivers through traffic information boards and makes suggestions for avoiding traffic congestion. The current judgement of the traffic congestion is based on the occupancy of the road which is one of traffic flow parameters. This occupancy is not so accuracy sometimes because of difficulty of 100 % vehicle sensing. In this paper, it describes the time zone basis traffic flow analysis in the traffic flow characteristics such as traffic density to average vehicle speed curve, traffic density to traffic volume curve, and traffic volume to average vehicle speed. This analysis is able to identify the effect of time zone to traffic flow condition and provide more appropriate occupancy level for traffic congestion.
