Evaluation Method of Bus Energy Consumption Based on Service Level

Based on the data of Beijing bus operation and energy consumption, the characteristic relationship of bus service level and energy consumption are quantified from the perspective of bus types, travel speed, load rate, and bus lanes. The research shows that there is negative correlation between the bus speed and the energy consumption per 100 km, but an obvious negative correlation between bus loaded rate and the energy consumption per 10 000 passenger-kilometers. For different bus types, the energy consumption per 100 km of the single bus is about 30%~40% less than that of the double decker bus, but the energy consumption per 10 000 passenger-kilometers of the single bus is about 5%~15% higher than that of the double decker bus. Finally, using the travel speed and load rate as the main parameters, the energy consumption model of bus based on the service level is constructed and applied for case study of bus energy conservation. The result indicates that when the loaded rate is above 60%, the decrease of energy consumption per 10 000 passenger-kilometers is slowing down. And when the average travel speed is lower than 40 km/h, increasing speed of buses can reduce energy consumption per capita. Copyright © 2018 by Science Press.
