Özet

Urban transport has been increasingly becoming a primary element m energy consumption Increasing car ownership causes urban sprawl and renders public transport ineffective Together these cause not only an increase in energy consumption but also inefficient energy consumption In this study, the factors that affect energy efficiency are specified and estimated by Stochastic Frontier Regression Model with available data of 75 cities in the world It is found that urban compactness increases energy efficiency in private and public transport Fuel cost is the most significant independent variable in private transport that promotes energy efficiency As for the public transit, reserved roads increase energy efficiency This study shows that employing policies effective for private transport as well as public transport in coordination might be the most effective tool in reducing cost instead of uncoordinated applications
