【 摘 要 】

The rapid growth in economy has resulted in an intense increase of personal vehicle usage which resulted in road traffic congestion in all metropolitan cities like Chennai, Bengaluru, etc. As Vellore has a good transportation network, it experienced a substantial urban growth especially after it becomes a city corporation in 2008. One of the ill or side effects of urbanization is traffic bottlenecks and before suggesting remedies to address the traffic problems, understanding the current situation is very important. Analysis of traffic flows or volumes at busy intersections in order to find the mode share percentage, directional distribution and peak period traffic volume is the first and foremost step to understand the present situation of traffic. Hence in the present study, a busy intersection in Vellore called Chittor bus stand intersection near VIT was selected and volume data was collected through video surveys. The collected flow or volume data was carefully examined to identify the modal share, directional distribution and morning & evening peak hour traffic volume. The results showed that the two wheelers and three wheelers comprise 82% of the total volume and the proportion of cars is only 11%. The traffic data analysis showed that the light commercial vehicles (LCV) and heavy motorized vehicles (HMV) constitute 7% of the total traffic. A highest hourly volume of 7573 PCU's was observed between 9.30 am and 10.30 am during morning and 7336 PCU's between 5.40 pm and 6.40 pm in evening. By taking a 10% growth in traffic every year, then in the year 2021, the traffic volume at the intersection may reach 10,000 PCU's and may warrant for a flyover or grade separator at the intersection.
