The invention discloses a road congestion judgment method based on a satellite remote sensing image. The traffic judgment method based on the satellite remote sensing image comprises the following steps: step 1, preparing data; 2, preprocessing the image; step 4, image matching; 5, extracting vehicle feature point positions in the matched image, wherein the vehicle feature point positions comprise single vehicle position information and global vehicle position information; and step 6, calculating the moving distance and the vehicle speed, and discriminating and evaluating the vehicle state through a traffic discrimination criterion. The road congestion judgment method based on the satellite remote sensing image can provide accurate traffic operation condition information for a traffic manager, and can be used as an input parameter of a traffic control system to optimize a regional road network; and secondly, when the guidance strategy is determined and the traffic information is published, traffic state analysis is scientifically carried out and can be better accepted by travelers, so that the overall efficiency of a traffic system is improved, and preparation for balanced development of cities and traffic is realized.
本发明公开了一种基于卫星遥感影像的道路拥堵判断方法,所述基于卫星遥感影像的交通判别方法:步骤一:数据准备;步骤二:图像预处理;步骤四:影像匹配;步骤五:提取匹配图像中车辆特征点位置,包括单个车辆位置信息以及全域车辆位置信息;步骤六:计算移动距离和车速,通过交通判别准则对车辆状态进行判别评价,本发明一种基于卫星遥感影像的道路拥堵判断方法,可以向交通管理者提供准确地交通运行状况信息,并可以作为交通控制系统的输人参数优化区域路网;其次,在确定诱导策略及发布交通信息时,科学地进行交通状态分析可以更好的被出行者所接受,因从而提高交通系统的总体效率、实现城市与交通的均衡发展的准备。
