摘要:

为了评估汽车共乘方式在中国推进的可行性,从能耗和出行时间价值视角建立汽车共乘边界模型,探索影响共乘方式推进因素,以西安小汽车出行为例,验证汽车共乘边界模型的科学性和准确性.结果显示,共乘方式油耗与增载旅客数呈强反相关关系,与旅客体重呈弱正相关关系,与旅客周转量增加率呈强正相关关系;西安市汽车共乘边界条件要满足增载旅客数大于1.37倍周转量增加率,旅客单位出行时间价值小于92.7元;按照10辆车增载1.37个乘客计,西安市一年可以节省燃油500万升,汽车共乘方式在西安具有很好的推进潜力.

Abstract:

The paper analyzes the feasibility of carpool in China, develops car pooling boundary model from the energy and time value and explores the impact of carpool promoting factors. Taking the panel data of Xi’an, China as an example, it verifies the car carpool boundary model. The results show that the fuel consumption of carpool has a strong anticorrelation with passenger number increase, and has a weak positive correlation with passenger weight. It also has a strong positive correlation with the increasing rate of passenger turnover volume. The pooling boundary of Xi’an should meet the condition that the increasing passenger volume is over 1.37 times than the increasing passenger turnover rate; the passenger unit of time value of less than 92.7 yuan. If there is 1.37 passenger number increase for every 10 vehicles, there will be 5 million liter’s fuel saving for Xi’an per year and the car carpool has good potential in Xi’an city.

Key words: urban traffic, car pooling, travel time value, saving energy
