Abstract

This study aims to calculate the number of bays needed in the design year 2037 for a toll plaza on the Bengaluru – Chennai Highway (National Highway No. 48). Data on the classified traffic volume count was gathered from the National Highway Authority of India (NHAI) office and relates to the “Nemili toll plaza” on the Bengaluru – Chennai Highway (NH-48). Average daily traffic is calculated using the tollable traffic data that has been gathered as a base. A suitable seasonal correction factor was assumed in order to estimate the annual average daily traffic. Using growth elasticity values derived from the Annual Average Growth Rates (AAGR) of Population, Per-Capita Income, and Net State Domestic Product of the influencing states collected from credible sources and state influencing factors, traffic in the horizon year (2037) was estimated. The necessary number of Electronic Toll Collection (FASTag) bays at the Nemili toll plaza was determined in accordance with Indian Road Congress standards based on the traffic flow forecast for the upcoming year.
