With the high growth of city traffic, the conflict between travel demand and supply has increased and the vehicular flow becomes congested. Traffic congestion can be characterized by the decline in speed, the increase in travel time and by the long queue on the road. Congestion happens when the volume exceeds the road capacity. Road intersection is not sustainable if its capacity exceeds the volume, but this condition exists only in certain intersections and it has dominated over entire city. Rajiv Gandhi Salai is an Expressway and Kelambakkam-Vandalur Road in South Chennai seems to be talk of the City. The volume of traffic on the IT Expressway corridor is more than three lakhs passenger car equivalence (PCE) on weekdays. This paper discusses more about how to manage the traffic volume at Kelambakkam intersection. To improve the traffic flow at the Kelambakkam intersection along Rajiv Gandhi Salai of South Chennai, traffic survey is conducted which include road inventory and volume count along the various arms towards the intersection. Volume accumulation curves are developed and peak volume and peak of peak time is obtained. From the analysis it is found that the peak volume is of 10719 PCE during 18.30 to 19.30 hours at this intersection. Volume to capacity ratio is found greater than one which makes high level of congestion and poor level of service. To manage this Transport System Management concepts are suggested in various scenarios which may reduce the volume lesser than the capacity.
