Abstract
The study focuses on assessing the behaviour of electric buses when replacing conventional fuel (diesel) buses in urban transit networks, through key performance indicators, considering stochastic weather and traffic conditions. A case study of one bus line in the city of Athens, Greece was analyzed using discrete event simulation, aiming to understand the service level that can be achieved by specific sizes of electric buses fleets and under stochastic scenarios of weather and traffic conditions. The aim was to achieve at least the current service level obtained using conventional buses. The simulation model developed models all energy-consuming subsystems of an electric bus and considers the exact route characteristics of a specific bus line. The results indicate that same size fleets of electric buses can achieve the same service level as conventional (diesel) buses under typical conditions; however, under more extreme conditions (e.g. very hot weather, increased traffic) the service level drops significantly and a much higher number of buses is required to bring it to the desired level. Additionally, a strategy where all electric buses were starting their shift at the same time would lead to extreme peaks in charger station traffic, which leads to management challenges.
