摘要：

为充分描述异质交通流条件下的车队离散规律，为信号协调控制提供理论基础，结合异质交通流条件下的车流特征和Robertson 模型计算速度快的优点，对多股交通流分别建模，并在此基础上构建异质交通流车队流量离散模型.通过实际调查数据，分析下游交叉口到达流率分布与上游交叉口离去流率分布之间的关系，并将本文模型和Robertson 模型与实际数据进行比较分析.结果表明，与Robertson 模型相比，本文模型能够更好地描述异质交通流条件下的车队离散规律，平均预测均方误差减少了8.29%.

Abstract:

To describe the law of platoon dispersion under the condition of heterogeneous traffic flow adequately, and provide theoretical support for traffic signal coordination, the characteristic of heterogeneous traffic flow and the virtue of fast calculation of Robertson' s model are considered. Then, a heterogeneous traffic flow platoon dispersion model is proposed based on modeling the multi different traffic flow. Later, the relationship of the arrival flow rate of the downstream intersection and the depart flow rate of the upstream intersection is analyzed using the proposed model by field collected data, with comparison to those of Robertson model and the actual data. The results show that, the proposed model can better describe the law of dispersion in heterogeneous traffic flow, and the mean squared error of prediction is reduced by about 8.29%, compared with Robertson model.

Key words: traffic engineering, platoon dispersion model, heterogeneous traffic flow, travel time, signal coordination
