摘要
针对已有高铁枢纽设施布局评价方法存在的不足,提出以乘客集散状况为核心的评价方法。基于乘客在枢纽核心区内的集散时间、集散距离分析,细化评价指标,选取平均集散时间、平均集散距离、90%乘客集散时间、90%乘客集散距离为具体指标。以乘客出行链为分析单元对传统的交通分配模型进行改进,提出具体指标的详细计算方法。以石家庄高铁枢纽规划设计为例,应用提出的评价方法对两个规划方案进行评价。结果显示,两个方案的平均集散时间为20~25 min、集散距离为700~2 000 m,均处于合理范围,但方案二交通集散效率更高,最终作为推荐方案。
Through addressing the deficiencies in evaluating high-speed rail station facilities,this paper presents an evaluation method mainly based on the efficiency of passengers’loading and unloading process.By analyzing passengers loading/unloading time and walking distance within the core area of a high speed rail station,the paper selects four evaluation indices： average loading/unloading time and distance,the 90 percentile loading/ unloading time and distance.The paper proposes the detailed computing method aiming to improve the existing traffic assignment model based on the analysis of passenger trip chain.Taking Shijiazhuang High Speed Rail Station as an example,the paper demonstrates the application of the method in evaluating two design scenarios for the facility.The results show that while both options satisfy the average loading/unloading time（20-25 minutes） and distance（700-2000 meters） requirements,the option two yields the higher efficiency.Thus,the option two is recommended for implementation.
