ASSESMENT OF TRAFFIC CONGESTION USING TRAFFIC CONGESTABILITY INDEX FOR BENGALURU CITY –A CASE STUDY

Abstract

Traffic congestion is one of the major problems in urban area which affects economy and safe & efficient
mobilization of people and goods. Traffic scenario in Bangalore city over past decade has undergone drastic changes with
the increase in number vehicles. Traffic management in and around the CBD’s has become a challenging task for both
traffic engineers and traffic police who are striving to minimize traffic related problems. In this regard an attempt has been
made in the present work to study behavior of traffic along north-south corridor of Bangalore i.e road connecting
Yelahanka and Banashankari to asses traffic congestion index.
Traffic congestion reduces the effective spatial interaction between different zones. Traffic congestion measurement is
important to understand traffic condition in the city. It is important to measure network traffic congestion instead of
measuring traffic congestion of single link. Present study mainly concentrates on network traffic congestion measurement.
Selected study area is from Banashankari to Yelahanka. The selected network includes outer ring road from Banashankari
to Yeshwanthapura, Tumkur main road,Chord road, Jalahalli road, Sandeep hunni krishan road and Mathikere road.
In the present work traffic congestion measurement was analysed considering new index property i.e. Traffic
Congestability Index (TCI) which has got both quantitative and qualitative parameters. Parameters such as Average speed,
delay time, Travel time and traffic volumes come under quantitative parameter. Pedestrian movement and surface
condition of pavement are comes under qualitative parameters. Lower value of TCI indicates higher degree of congestion
and vice versa.
