Emission Reduction in Urban Environments by Replacing Conventional City Buses with Electric Bus Technology: A Case Study of Pakistan

Abstract

The global transportation industry has become one of the main contributors to air pollution. Consequently, electric buses and green transportation are gaining popularity as crucial steps to reduce emission concerns. Many developed countries have already adopted the concept of Battery Electric Buses (BEBs), while the developing ones are just starting with it. However, BEB fleets have advantages, such as lower fuel, higher efficiency, lower maintenance, and energy security. Yet, several obstacles must be overcome to support the mass deployment of BEBs. These incorporate forthright expense charges, arranging loads, BEB reach, and newness to BEB innovation. Stakeholders like policymakers, private company owners, and government leaders have a lot to consider before introducing BEBs at any level in Pakistan. As a result, to operate an electric bus system profitably, it is crucial to develop a proper electric bus network and fleet, especially for bus operators who need to buy enough electric buses at the appropriate time. As a result, this paper aims to investigate if operating an electric bus could be an alternative to regular bus operations. The proposed methodology develops modeling software to cater to various scenarios to determine a proper-designed electric bus operating system in terms of the electric bus route, service frequency, and quantity. This research work simulates and financially analyses an operating Public Transport Infrastructure with a proposed Green Solution. The results show that regardless of the high upfront costs of BEB infrastructure, it becomes profitable in 6-7 years, resulting in a decreased Total Cost of Ownership (TCO) of approximately 30% of its counterpart. The study also provides a clear policy pathway to help stakeholders make informed decisions related to the electrification of public transport in Pakistan.
