摘要:
为了定量分析停车换乘(P&R)出行方式的时间可靠性,提出了一种P&R行程时间可靠性计算算法并进行求解.将P&R出行过程按照出行特征划分为小汽车、停车搜索、步行及轨道交通4个出行子链,在拟合和标定各子链行程时间分布的基础上,基于结构可靠性计算中的HL-RF算法设计求解算法.通过当量正态化法(RF)将各出行子链的行程时间分布转换为对应的当量正态分布,然后利用验算点法(HL)计算P&R行程时间可靠度.最后,以实际案例验证所提算法.结果表明,该算法能够简洁有效地计算P&R出行行程时间可靠性,且计算中考虑了P&R各出行子链行程时间服从不同时间分布的情况.
Abstract:
In order to quantitatively analyze the travel time reliability of park-and-ride(P&R)trips, a solution algorithm is proposed and solved. The P&R trip is divided into four subchains, including auto, parking search, walk, and metro. Based on the fitting and calibration of the travel time distribution of each subchain, the Hasofer-Lind-Rackwitz-Fiessler(HL-RF)algorithm, widely used in the calculation of structural reliability, is used to design a solution algorithm. First, the travel time distribution of each subchain is converted to the corresponding normal distribution according to the RF method. Then, the HL method is used to calculate the travel time reliability of the P&R trip. Finally, a case is used to prove the effectiveness of the proposed algorithm.The results show that this algorithm can concisely and efficiently calculate the travel time reliability of the P&R trip. In the calculation, the cases for travel time of subchains following different distributions are considered.
