Abstract

Climate change has generated a growing interest in green technologies and their integration across various economic sectors. This has significantly impacted the automotive industry, particularly the rapid bus transit (BRT) system, which currently relies on internal combustion engine vehicles, resulting in high greenhouse gas emissions that affect the city’s air quality. In response, companies have focused on incorporating electric vehicles into their fleets and assessing their impact on route distribution. Due to the expenses associated with purchasing new vehicles and the necessary adaptations to parking facilities for potential charging, a gradual transition to a mixed fleet of electric and traditional vehicles is being pursued. To address this challenge, the Mixed Fleet Vehicle Scheduling Problem (MFCSP) aims to optimize driver assignments and routes, considering operational efficiency and electric vehicle autonomy limitations. In this specific study, a modified mathematical model is proposed for the Megabus mass transit system in Pereira, Colombia, considering Integra S.A.'s future modernization plans.
