摘　　要：为获得更为合理的公交客流分配结果,引入库仑定律,根据公交站点在交通小区中的分布情况,分别建立了小区间和小区内的公交站点OD矩阵生成模型;然后,根据不同公交方式站点的特性对模型进行了优化,并通过对灵敏度系数的分析建立了灵敏度系数的求解模型;最后,通过实例对模型的有效性进行了验证.结果表明:文中模型具有较高的理论和实用价值,提高了公交客流预测的可靠程度.In order to obtain a reasonable public transit assignment,by introducing the Coulomb＆#39;s Law,intercell and intracell models for generating transit station OD matrix are proposed according to the distribution of transit sta-tions in a traffic zone.Then,the models are optimized according to the characteristics of different transit stations. Moreover,a sensitivity coefficient analysis is carried out and the corresponding solving model is constructed.Final-ly,the effectiveness of the model is verified through a case study.The results show that the proposed model is of high theoretical and practical value and helps to improve the reliability of the forecast of transit passenger flow.
