Traffic Growth Rate Estimation Using Transport Demand Elasticity Method: A Case Study of Sastapur – Narayanpet Stretch

Abstract

Road network plays a key role in the development of a country. For improving and developing
the highways for better national economy, traffic forecasting is significant. The knowledge
about the present and future traffic flow will help in the planning and designing of the road.
Therefore estimation of traffic growth rate is very important. This paper is a case study of
road stretch from Sastapur to Narayanpet which has a length of 200.914 km. This study
includes the estimation of traffic growth rate by using the present traffic, past trend and
socio economic variables.
This paper also includes the present level of traffic and various characteristics like average
daily traffic, annual average daily traffic, seasonal correction factor, origin and destination
analysis, traffic projection and the capacity assessment of the road stretch. Based on the study
it is observed that the road is not sustainable for the present traffic and widening is required.
