摘要 提高私人汽车利用率是缓解城市交通拥挤、减少能源消耗和环境污染的一个创新途径,车辆合乘是产生于民间的一种应对交通拥堵的新型方式.针对实际生活中居民对出行方式的选取,构建基于出行选择效用理论的函数模型,建立效用函数,通过类比选择更优的结果.综合考虑费用、时间、距离、机动车车速等指标作为参考点,考虑不同交通工具下效用值的大小,利用效用差值分析合乘的出行选择条件,通过算例验证了该方法的准确性.结果表明,由于出行距离长度的不同,合乘的效用值相比其他交通工具有所变化.根据出行距离可判断选择合适的交通工具,这对居民出行选择提供了现实依据. It is an innovative way to reduce energy consumption, environmental pollution and ease urban traffic congestion by improving the utilization of private cars. To deal with traffic congestion folk, carpooling can be regarded as a new way. For the real-life residents who want to select the travel mode, it can be constructed the selection function model based on travel utility theory, built a utility function and can be chosen better results by contrasting in this paper. In order to find the travel condition of carpooling, it can take the cost, time, distance, vehicle speed and other indicators as reference point, calculate the size of utility value, then use the effect error. Finally, the proposed model was validated by illustrating an example. The findings suggest that because of different travel distance, the utility value change comparing to other means of transportation. The conclusion of this paper indicates that, it can determine the appropriate means of transportation according to the travel distance, and provides a theoretical basis for the selection of resident trip.
