Road network with roadscape vectors in Awaji Island, Japan

<p><strong>Summary</strong><br>This dataset contains road network with roadscape vectors in Awaji Island, Japan. The road network data is derived from OpenStreetMap, and it consists of 102,506 road nodes and 212,050 road links in the area of Awaji Island. Roadscape vectors are given to each road link.</p> <p><strong>Road network data</strong><br>A road network is a directed graph G = (V, E), where &nbsp;V is a road node set and E &sube; V &times; V is a road link set. A road node vi &isin; V represents an intersection or an end point. A road link ek = (vi, vj) &isin; E represents a directed link from the starting node vi to the ending node vj.</p> <p><strong>Road nodes data</strong><br><code>m_road_nodes_latlng.csv</code><br>Road nodes are contained in the file m_road_nodes_latlng.csv. The number of road nodes is 102,506. Each line corresponds to one node. &nbsp;These lines have the following format as tab delimited:&nbsp;<br><code>node_id, lat, lng</code><br>Here, node_id denotes a road node ID for identifying a road node. lat and lng denote latitude and longitude, respectively.</p> <p><strong>Road links data</strong><br><code>m_road_links_nodes.csv</code><br>Road links are contained in the file m_road_links_nodes.csv. The number of road links is 212,050. Each line corresponds to &nbsp;one link. These lines have the following format as tab delimited:&nbsp;<br><code>link_id, start_node_id, end_node_id</code><br>Here, link_id denotes a road link ID for identifying a road link. start_node_id and end_node_id denote starting node ID and ending node ID, which refer to node_id in the file m_road_nodes_latlng.csv (i.e. the same node ID refers to the same road node across these files), respectively.</p> <p><strong>Roadscape vectors</strong><br>A roadscape vector is defined as a four-dimensional probability vector composed of four kinds of roadscape elements, rural, mountainous, waterside, and urban elements. Each element of the vector denotes the probability of including the roadscape element. Therefore, the sum of values over all elements is 1.</p> <p><strong>Road link vectors data</strong><br><code>m_road_links_vector.csv</code><br>Roadscape vectors of road links are contained in the file m_road_links_vector.csv. Each line corresponds to one link with its roadscape vector. These lines have the following format as tab delimited:&nbsp;<br><code>link_id, rural, mountain, water, urban</code><br>Here, link_id denotes a road link ID, which refer to link_id in the file m_road_lonks_nodes.csv (i.e. the same link ID referes to the same road link across these files). The rural, mountain, water, and urban denote rural, mountainous, waterside, urban elements in its roadscape vector, respectively.</p> <p><strong>Citation<br></strong>To make use of the dataset, please cite the following paper:<strong><br></strong></p> <ol> <li>Koji Kawamata and Kenta Oku.
