在分析目前城市快速路实际使用的入口控制模型的基础上，引入时空资源效用参数作为控制变量，将并行多路任务负载均衡模型与传统ALINEA策略相结合，提出了以主辅路资源效用均衡化为主导思想的城市快速路入口均衡控制模型（TBM）. 为提高模型的实用性，本文提出“非对称性改进”和“局部出入口弱互扰情况下的资源折减”这两项改进措施，并将改进的NEMA排队感应模型作为回溢的控制手段. 以合肥金寨路高架桥为背景，进行实地测试，结果表明主路平均行程时间减少了9.09%~9.44%，局部拥挤现象明显减少. 最后讨论了控制模型在不同交通条件下的适用性，均衡控制模型在高峰时段，特别是在主辅路局部拥挤程度不同的条件下，局部拥挤的改善效果比较显著.

Expressway Entrance Control Based on Task Balancing Model

Based on the analysis of the actual use of urban expressway entrance control model, the method of entrance control based on the task balancing control (TBC) is introduced in this paper. The measure of effectiveness (MOE) is set as the indicator of TBC model, and the control model on the systems with multiple parallel plants (MPP system) is integrated with the ALINEA model. This model focuses on the balance of expressway and auxiliary traffic demand. To improve the practicability of the model, this paper proposes two improvements: asymmetry parameters and local reduction coefficient in the weak interacting conditions, and also applies the improved queue induction model of NEMA to control overflowing. This TBC model is validated on the viaduct of Jinzhai Street in Hefei province, and the travel time of expressway is reduced by 9.09%-9.44%. Finally, the adaptability of the TBC model under different conditions is introduced. This model has significant effect of improving local congestion, especially during the rush hour under different crowded degree between expressway and auxiliary road.
