城市交通发展规模与交通资源适应性模型及算法

Model and Algorithm of Adaptation Analysis Between Transportation Resources and Transportation Development Scale

为科学确定城市交通的发展规模,在分析关键交叉口转向能力的基础上,提出了基于超级节点的城市交通网络构建方法;考虑公交资源以及公交优先发展战略的因素,构建了城市交通发展规模与交通资源适应性的数学模型,并设计了基于反馈的免疫克隆算法.以城市内某一区域为例对模型和算法进行验证,结果表明:模型及算法具有较好的实用性,能够为城市交通规划部门提供良好的决策支持.

To reasonably determine the transportation development scale, the turn capacity of key intersections was analyzed. Then the transportation network based on the super node was constructed. A mathematic model of adaptation analysis between the transportation resources and transportation development scale was established by considering the factors of bus resource and the bus priority development strategy,and an immune clone algorithm based on feedback strategy was used to verify the model. The result shows that the model and the algorithm are of good applicability,which provides reference for decision-making to the traffic planning department.
