Analysing driving patterns of electric taxi based on the location of charging station in urban area

Abstract

As electric vehicles are more adopted extensively, the charging station location and distribution problem is becoming more important. Efficient charging station planning can solve major problems, such as driving-range anxiety and the stagnation of new electric vehicle consumers. For efficient charging station planning, the influence of charging station location should be identified. This paper analyzes the electric taxi's driving patterns with constraint of insufficient charging stations. Comparing the driving patterns between general taxi and electric taxi, specific driving patterns can be revealed due to the location of charging station. Daejeon city in South Korea is selected for the experiment study area to examine the difference of driving patterns. The driving patterns caused by charging behavior are analyzed by real taxi trajectory data. In this study, the measures of driving patterns are analyzed by the sum of trip length in each cell and origin-destination direction pattern with the real data of taxis. In the initial planning phase of installing charging stations, the results of this paper can be efficiently applied to a relatively extensive area to encourage the usage of electric vehicles.
