摘要：
Improving driving behavior and promoting eco-driving are important approaches to reduce fuel consumption and pollution emissions of on-road vehicles in the future. We collect on-board diagnostic (OBD) system data with the position, speed, and fuel consumption per second from 199 heavy-duty freight vehicles in four days. We propose statistical measures to judge five inefficient driving behaviors, including rapid acceleration, over-rapid acceleration, rapid deceleration, over-rapid deceleration, and excess idle time. We further establish a panel data based fixed effects model to estimate the effects of inefficient driving behaviors on fuel efficiency as well as fuel-saving potentials of improving these behaviors. Our results show that excess idle time and over-rapid deceleration significantly increase fuel consumption, and the fuel-saving potentials are 2.6% and 3.8%, respectively.
