OSM 是由「資料」組成 Map Data © OpenStreetMap contributors under ODBL, Tiles

OSM 的資料形式 節點(商店、站牌) 路徑 / 區域(道路、建築) 關係
關係 ⼀一個由「多個」不同元素組成的集合 關係本⾝身有⾃自⼰己的「標籤」 包含名稱與類型(⾃自⾏行⾞車道、公⾞車路線)等資訊 包含⼀一個「有順序的列表」 列表內會有多個節點、路徑或關係作為「成員」

公⾞車關係 「標籤」敘述公⾞車路線的服務資訊 名稱(編號)、系統或主管機關、起訖點 「成員」會包含公⾞車經過的道路,停靠站牌,調度站 「道路」⼜又會分⾏行進的⽅方向(forward or backward) 以建⽴立不同的關係來表達正線、區間⾞車、副線、直達 ⾞車等路線種類(並建⽴立⼤大關係包含這些關係)

OpenStreetMap contributors under ODBL,
Why bus routes on OSM? 有更適當的平台能表現公⾞車資訊 可以使⽤用 Transport Map 加以圖形化
使這些資訊能以 OSM 的資料庫整合並加以利⽤用
臺灣⼤大眾運輸路線 OSM 繪製概況
⼤大眾運輸在 OSM ⺫⽬目前已經開始系統化編輯的區域: ⼤大台北(台北、新北、基隆) 桃園 台南 ⾼高雄
歷史 ⼀一開始是從⾼高雄市開始 後來陸續有台南和基隆區域的繪製 近期是⼤大台北區域(⽂文⼭山、新店、中和)的系統化 站牌與路線建制
站牌怎麼標才對? 利⽤用可以紀錄航點的 GPS 編輯器 例如 OSMTracker for Android Taken by

未來計畫 提倡站牌 / 路線資料 Open Data,甚⾄至匯⼊入 OSM(授 權問題) ⽤用CC授權,將維基上公⾞車路線資料移到 OSM
Wiki 整理台北與⾼高雄的公⾞車路線和 OSM 關係列表 公路、鐵路路線,台鐵、⾼高鐵列⾞車資料也能⽤用類似 ⽅方式處理
謝謝⼤大家
