该体系结构由城市道路交通网络结构模型、交通生成模型、车辆行驶行为模型、城市道路交通网络分析模型四类模型组成。
It includes urban road traffic net structure model, traffic flow generation model, vehicle run behavior model, and urban road traffic net analysis model.
传统的交通需求4阶段分析模型大多基于各类出行的起讫点调查(OD调查)，建立出行生成、出行分布、出行方式选择和流量分配的4阶段预测模式。
The traditional travel demand model usually bases itself on the od study survey and employs a 4-step modeling process including trip generation, trip distribution, mode choice and assignment.
出行生成模型：交通小区通达性和便利程度在很大程度上影响着居民的交通生成量，传统的出行生成预测模型无法反映这一特征。
This model demonstrates how the socioeconomic variable, traffic serving level and the socioeconomic variable around traffic zones contributes to the trip generations.
