اثرات ناشی از ترافیک بر روی امکان سنجی پروژه بزرگراه با استفاده از تجزیه و تحلیل اقتصادی: مطالعه موردی در هند

Induced travel that alters the traffic growth rate of highway projects and their economic impacts has been studied in this paper. Most of the researchers on induced traffic have used the static lane-km elasticity, whereas it is in fact change in travel cost that users react to when the lane-km changes. Hence, this work uses travel-cost elasticity and studies the effects of induced traffic for an Indian highway project in terms of economic impacts and compares the results with the conventional lane-km elasticity method. It has been found from this study that considering induced traffic by both these methods changes the economic indicators by different amounts. Hence, ascertaining the best method by comparing with real traffic counts assumes great importance. This paper also suggests preferring travel cost elasticity as even lane-km indirectly accounts to travel cost savings due to additional lane-km added to the facility.
