基于多源数据的慢行交通评价方法及导控策略

Non-motorized Traffic Evaluation Method And Guidance And Control Strategy Based On Multi-Source Data

科学评价慢行交通系统亟需一套综合、量化的评价方法。通过融合OSM路网、街景、POI等多源数据,该文对慢行交通系统空间属性数据进行识别分析,选取以便捷性、舒适性、功能性和安全性为核心的评价指标,利用改进物元组合赋权模型构建慢行交通综合评价体系,并提出导控策略,将该评价方法应用于广州市越秀区轨道交通站点周边慢行交通综合评价,验证了该评价方法可有效提高评价结果科学性和适用性,并可根据评价结果采取针对性优化策略。

Scientific evaluation of non-motorized traffic system urgently needs a set of comprehensive and quantitative evaluation methods.By integrating OSM road network,streetscape,POI and other multi-source data,this paper identifies and analyzes the spatial attribute data of non-motorized traffic system,selects the evaluation indicators with convenience,comfort,functionality and safety as the core,uses the improved matter-element combination weighting model to build a comprehensive evaluation system for non-motorized traffic,and proposes guidance and control strategies,The evaluation method is applied to the comprehensive evaluation of non-motorized traffic around the rail transit station in Yuexiu District,Guangzhou,and it is verified that the evaluation method can effectively improve the scientificity and applicability of the evaluation results,and can take targeted optimization strategies according to the evaluation results.
