城市路网交通供需数据集

本数据集基于多源权威数据采集构建，面向多模式出行以及未来自动驾驶与人工驾驶车混行场景，支撑深圳市福田区多模式交通供需建模与网络流均衡分析，数据涵盖道路网络拓扑与居民分方式出行两类核心数据。
道路网络数据以OpenStreetMap（OSM）开源地图为基础，自动化提取节点、边、道路等级、长度等关键结构信息。为提升路网拓扑数据的完整性与几何精度，在原始数据基础上进行了拓扑重构和断点剔除处理，并结合福田区实地交通图层及公开规划资料进行人工校核与缺失补全。重点针对高等级道路、关键节点与边界过渡区域开展结构修复，确保路网数据在空间连接性与几何一致性上的可靠性。道路容量参数严格参照《城市道路工程设计规范》进行赋值，并结合区域交通管控政策进行修正，构建出具备工程实用性的道路容量体系。上述流程确保了路网数据在源头来源、处理过程和建模应用中的稳定性与可用性。
本数据集最终分为深圳市福田区全域道路交通网络与居民出行数据。具体包括：（1）路网拓扑：路段起点、路段终点、路段长度、路段等级、路段设计通行能力。（2）居民分方式OD出行数据：OD对起点、OD对终点、当前小汽车OD量、公交车OD量、未来人驾车OD量、自动驾驶汽车OD量。数据量大小为1.7MB。

This dataset is constructed based on multi-source authoritative data collection, targeting multi-modal travel and future mixed-traffic scenarios of autonomous and human-driven vehicles, to support multi-modal traffic supply-demand modeling and network flow equilibrium analysis in Futian District, Shenzhen. It covers two core types of data: road network topology and resident travel data categorized by travel mode.

The road network data is based on the open-source map of OpenStreetMap (OSM), where key structural information such as nodes, edges, road hierarchy and length is automatically extracted. To improve the integrity and geometric accuracy of the road network topology data, topology reconstruction and broken-link removal are performed on the original data, followed by manual verification and missing data completion combined with field traffic layers and public planning documents of Futian District. Structural repairs are focused on high-grade roads, key nodes and border transition areas to ensure the reliability of the road network data in terms of spatial connectivity and geometric consistency. Road capacity parameters are assigned strictly in accordance with the *Code for Design of Urban Road Engineering* and revised in combination with regional traffic control policies, thus establishing a road capacity system with engineering practicality. The above process ensures the stability and availability of the road network data in terms of source origin, processing procedure and modeling application.

This dataset is finally divided into two parts: the full-domain road traffic network of Futian District, Shenzhen, and resident travel data. Specifically, it includes: (1) Road network topology: starting point of road segment, ending point of road segment, length of road segment, road segment hierarchy, designed traffic capacity of road segment. (2) Origin-destination (OD) travel data of residents categorized by travel mode: starting point of OD pair, ending point of OD pair, current passenger car OD volume, bus OD volume, future human-driven vehicle OD volume, autonomous vehicle OD volume. The total size of the dataset is 1.7 MB.
