摘要: 针对城际交通方式合理规划问题,对交通方式分担率进行了研究。首先,结合非集计理论与随机效用理论建立效用函数,利用极大似然估计法计算效用函数权重,并考虑不同收入出行者对权重的影响;其次,考虑不同交通方式间存在相关性,用相对效用代替绝对效用,建立了改进的巢式Logit模型;最后,结合分担率模型和武汉至咸宁旅客的调查结果,计算各交通方式的分担率。通过计算结果与巢式Logit模型及实际客运分担率进行对比,验证了模型的可行性和有效性,对今后城际交通方式的划分和管理具有重要的指导意义和参考价值。

Abstract: Aiming at the reasonable planning of intercity traffic mode, the share rate of traffic mode was investigated. Firstly, the utility function was established by disaggregate theory and random utility theory, whose weight was calculated by maximum likelihood estimation, and the influence of travelers with different income on the weight was considered. Then, considering the correlation among different traffic modes, the relative utility was used to take the place of the absolute utility; and the improved nested Logit model was established. Finally, the share rates of various traffic modes were calculated, combining with the share rate models and the questionnaire results of travelers from Wuhan to Xianning. The feasibility and effectiveness of the proposed model was verified by comparing with the calculation results,the nested Logit model and the actual share rate of passenger flow.The proposed model has important guiding significance and reference value for the future division and management of intercity traffic modes.

Key words: traffic engineering, intercity traffic, share rate, utility function, nested Logit mode
