OpenStreetMap (OSM) is a free map of the world which can be edited by globalvolunteers. Existing studies have showed that completeness of OSM road data insome developing countries (e.g. China) is much lower, resulting in concern inutilizing the data in various applications. But very few have focused oninvestigating what types of road are still poorly mapped. This study aims notonly to investigate the completeness of OSM road datasets in China but also toinvestigate what types of road (called omission roads) have not been mapped,which is achieved by referring to both Street Map and Street View. 16prefecture-level divisions in the urban areas of Hubei (China) were used asstudy areas. Results showed that: (1) the completeness for mostprefecture-level divisions was at a low-to-medium level; most roads (in theStreet Map), however, with traffic conditions had already been mapped well. (2)Most of the omission OSM roads were either private roads, or public roads nothaving yet been named and with only one single lane, indicating their lack ofimportance in the urban road network. We argue that although the OSM roaddatasets in China are incomplete, they may still be used for severalapplications.
