摘要
文中从高架桥桥墩设置形式、高架桥桥墩处中央隔离带优化两个方面出发,利用公式推导、实测、VISSIM建模等三种优化,拟合推导出利用高架桥桥墩所在中央隔离带在交叉口处增设左转车道长度与通行能力变化的函数关系,并验证其准确性.同时对利用桥墩所在中央隔离带设置提前掉头和BRT专用道对交叉口通行能力影响展开研究.
Taking the setting form of viaduct pier and the optimization of central isolation belt at viaduct pier as the research object, the functional relationship between the length of left-turn lane at the intersection and the change of traffic capacity by using formula derivation, actual measurement and Vissim modeling was fitted and deduced, and its accuracy was verified. Meanwhile, the influence of using the central isolation belt where the pier is located to set up early U-turn and BRT lane on the intersection capacity was studied.
