基于视频识别检测数据的机动车OD 分析

摘要

交通检测技术的快速发展为机动车 OD分析提供新思路，利用视频识别检测数据，开展 OD 模型推导研究。针对既有研究多基于交通仿真平台，对交通特性体现不全面的缺陷，研究在提出路径补充模型和 OD 补充模型的基础上，采用北京市五环内某路网检测数据进行实证分析，经精度检验获得最佳路径补充模型，并分析了检测器布设对于 OD精度的影响。%The rapid development of traffic detection technology provides new ideas to analyze the automobile OD matrix.Using the video identification data,we make a research on OD matrix model deri-vation.As most of the existing researches are based on traffic simulation platform and not completely re-flect traffic characters,in this paper,based on the proposal of path replenish model and OD replenish model,we adopt the data of a part of road networks in Beijing to make an empirical analysis,and get the best path replenish model according to accuracy tests.At last,the accuracy of OD data which is influenced by location of detectors is quantitative studied.
