基于梯度法的OD矩阵估计和应用研究
OD matrix estimate based on gradient approach and research on its application
【摘要】 以交通规划软件EMME/2为平台,在拥有合理的原始矩阵和一定数量的路段实测流量数据的基础上,运用梯度法(最速下降法)求出OD矩阵估计.结合具体的课题研究应用情况,证明该方法适用于大规模实际路网.
【Abstract】 In the process of transportation planning,control and management,OD matrix estimate is the important basic data.How to get OD matrix estimate is a hotspot in the transportation research.Based on EMME/2,and having a rational original OD matrix and enough observed volumes of links,by use of gradient approach,OD matrix estimate is obtained.It is suitable for large scale networks in practical applications.
