Multilane roads extracted from the OpenStreetMap urban road network using random forests

摘要

Abstract >The volunteered geographic information (VGI) collected in OpenStreetMap (OSM) has been used in many applications. Extracting multilane roads and establishing a high level of expressed detail play important roles in the field of automated cartographic generalization. An accurate and detailed extraction process benefits geographic analysis, urban region division, and road network construction, as well as transportation applications services. The road networks in OSM have a high level of detail and complex structures; however, they also include many duplicate lines, which degrade the efficiency and increase the difficulty of extracting multilane roads. To resolve these problems, this work proposes a machine‐learning‐based approach, in which the road networks are first converted from lines to polygons. Then, various geometric descriptors, including compactness, width, circularity, area, perimeter, complexity, parallelism, shape descriptor, and width‐to‐length ratio, are used to train a random forest (RF) classifier and identify the candidates. Finally, another RF is trained to evaluate the candidates using all the geometric descriptors and topological features; the outputs of this second trained RF are the predicted multilane roads. An experiment using OSM data from Beijing, China validated the proposed method, which achieves a highly effective performance when extracting multilane roads from OSM. </abstract> </span> <span

>志愿的地理信息（VGI）收集在OpenStreetMap中（OSM）已被用于许多应用程序。提取多层道路并建立高水平的表达细节在自动制图概括领域发挥重要作用。准确和详细的提取过程效益地理分析，城市地区部门和道路网络建设，以及运输应用服务。 OSM中的道路网络具有高水平的细节和复杂的结构;然而，它们还包括许多重复的线条，这降低了效率并增加了提取多金银艇道路的难度。为了解决这些问题，这项工作提出了一种基于机器学习的方法，其中道路网络首先从线路转换为多边形。然后，各种几何描述符，包括紧凑性，宽度，圆形度，面积，周边，复杂性，并行性，形状描述符和宽度到长度比，用于训练随机林（RF）分类器并识别候选者。最后，训练另一个RF以使用所有几何描述符和拓扑特征来评估候选者;第二训练RF的输出是预测的多金银艇道路。中国使用OSM数据的实验，中国验证了拟议的方法，在从OSM中提取多金属道路时实现了高效的性能。</
