面向交通资源整合的大城市公铁枢纽联合布局模式

为了同步优化公铁枢纽布局与集散交通资源配置,分析了不同等级公铁枢纽布局关系,建立了枢纽客流集散评价模型,提出了公铁枢纽联合布局模式。分析结果表明,大城市核心区以市郊铁路枢纽独立布局较为理想,中圈层适宜采用"市郊铁路 普通级公路客运枢纽"、"普通铁路 都市圈级公路枢纽"或"普通铁路 普通级公路枢纽"的联合布局模式,外圈层以"市郊铁路 普通级公路枢纽"、"市郊铁路 快速级公路枢纽"、"高速铁路 普通级公路枢纽"或"高速铁路 快速级公路枢纽"的联合模式较优;在站场布置方面,竞争为主或完全竞争型宜布置为异站异场或异站同场式,协作为主或完全协作型以同站同场或异站同场式布置较优。该布局模式在典型大城市具有良好的适用性,能降低交通负荷,满足交通需求。

Combined layout mode of metropolitan highway-railway transport hubs based on integration of traffic resources

In order to optimize the layout of highway-railway transport hubs and the allocation of distribution traffic resources, the layout relationships of highway-railway hubs at different levels were analyzed, a distribution evaluation model of hub passenger flow was built, and a combined layout mode of highway-railway hubs was presented. Analysis result indicates that the independent layout mode of suburban railway hub is appropriate to the downtown area of megacity, "suburban railway general highway hub" mode, "general railway metropolitan-area highway hub" mode and "general railway general highway hub" mode are appropriate to middle-circle layer area, "suburban railway general highway hub" mode, "suburban railway rapid highway hub" mode, "high-speed railway general highway hub" mode, and "high-speed railway rapid highway hub" mode are appropriate to outer-circle layer area; for the different distribution modes of combined highway-railway hubs, competition-dominated mode or complete competition mode is appropriate to "different station-different yard" layout or "different station-same yard" layout, and cooperation-dominated mode or complete cooperation mode is appropriate to "same station-same yard" layout or "different station-same yard" layout. The layout modes can reduce traffic burden, satisfy traffic demand and show great applicability in typical megacities. 5 tabs, 3 figs, 15 refs.
