Korea Road Network ETA (v3) 是一个韩国道路网络数据集，涵盖16个大都市区域，包括首尔、釜山、大邱等。数据集基于OpenStreetMap拓扑（2026年提取）和韩国交通数据库（KTDB）的时段通行速度（2024年观测），提供节点和边的Parquet文件，其中边文件附有时段平均通行速度（p50，单位km/h），支持工作日和周末的不同时间段（如高峰、非高峰）。该数据集可直接用于预计到达时间（ETA）计算、路由优化和调度模拟，适用于交通研究和应用。Korea Road Network ETA (v3) is a road network dataset for South Korea, covering 16 metropolitan regions including Seoul, Busan, Daegu, and others. It provides OpenStreetMap-based topology (extracted in 2026) with time-specific average travel speeds (p50, in km/h) from the Korea Transportation DB (KTDB, observed in 2024), delivered as Parquet files for nodes and edges. The edge files include speed columns for weekdays and weekends across multiple time slots (e.g., peak and off-peak). This dataset is designed for direct use in estimated time of arrival (ETA) calculation, routing, and dispatch simulation, supporting transportation research and applications.
