摘要： 基于天津市2011 年综合交通调查数据，天津市在现有 交通模型基础上构建了新的综合交通模型，以满足新形势下 城市与交通发展对交通定量分析的需要。新的综合交通模型 仍然采用基于出行的四阶段交通模型，但通过对人口、就业岗 位模型，出行产生模型，出行分布模型，方式划分模型，分配模 型等模块中关键技术的探索，不仅使模型能够有效反映当前 天津市“双城”结构下的居民出行特征，其框架具有较高的灵 活性和良好的扩展性，同时还为下一步建立基于活动的模型 奠定基础。实践表明，新的综合交通模型大幅提高了现有交 通模型的精度和分析能力。

Abstract： To satisfy the requirement of quantitative analysis by city and transportation development, Tianjin develops a new comprehensive transportation model based on existing models using data from the 2011 comprehensive transportation survey. The new model still adopts the traditional four-stage framework, but examines certain critical issues in the population model, trip generation model, trip distribution model, mode choice model, and traffic assignment model. The new model not only effectively captures the residents’commuting characteristics in the“Dual- City”structure of Tianjin with high flexibility and good expansibility, but also sets the foundation for developing activity- based models in the future. The application results show that the new model has greatly improved the existing models’accuracy and analytical capability.
