事件状态下城市快速路交通通道优化控制模型

交通控制和管理是解决城市交通拥挤问题的有效措施。在事件状态下，对快速路交通通道的优化拉制建模进行了研究．以快速路和干道交叉口的交通需求与通行能力的方差和最小为优化目标，建立了快速路交通通道优化控制模型，该模型同时优化干道交叉口绿信比、事件上游出口匝道转秽率和事件下游入口匝道转秽率三个控制参数。最后对目标函数进行了评述，表明谊优化控制模型简单实用。

Optimal Control Model for Urban Freeway Corridor under Incident Conditions

Traffic control and management are effective measures to solve the problems of traffic jam. The optimal control model for freeway corridor is developed under incident conditions, which is in the form of minimization of the summation of the square of the difference between traffic demand and capacity at each intersection and on the freeway bottleneck section. The model optimizes control parameters of phase splits at arterial interactions, off-ramp diversion rates at upstream offramps and on-ramp diversion rates at downstream on ramps. In the end, the objective function is discussed and the optimal control model proved simple and practical.
