- 摘要：
技术分析是绿道精细化选线的重要手段，文章根据城市绿道特点，构建“两类三层次”的城市绿道精细化选线技术体系。“两类”是指将城市绿道分为资源游憩类和慢行交通类两种主要的选线模式，前者是以目标为导向，重点实现城区重要游憩资源高效串接，后者是以需求为导向，重点研究并满足居民实际慢行（以骑行为代表）诉求。“三层次”是指利用资源类和行为轨迹类等多源数据，结合ArcGIS 网络模型、百度地图智能选线API、空间句法模型等技术，形成“节点聚合提取、线路连接构建、网络评价优化”3 个层次的选线步骤。最后以武汉市主城区城市绿道选线为例，判断该方法具有一定应用前景。 - 关键词：

The ¡°two types¡± divide urban greenways into resource recreation and slow traffic types. The former is goal-oriented, focusing on the efficient connection of signifi cant recreational resources in urban areas; while the latter is demandoriented, mainly addressing and fulfilling the residents¡¯ actual slow-motion (primarily cycling) needs. The ¡°three levels¡± leverage various data types, including resources and behavioral trajectories, and combines technologies like the ArcGIS network model, Baidu Map intelligent route selection API, and spatial syntax models to form a route selection process of ¡°node aggregation extraction, route connection construction, and network evaluation optimization¡±. Using the urban greenway route selection in the main urban area of Wuhan as an example, this study shows that this method has a certain application prospect.
