This research presents an analytical model for the coupled design of an urban transit network and an interurban one supported by park-and-ride facilities. The former network facilitates the mobility in the centre of the metropolitan area while the interurban services satisfy the centripetal connections from the metropolitan outskirts where park-and-rides are scattered. These three components of the system are interconnected. Both networks share common transfer stops in the main corridors of the central city while park-and-rides are the access points to the interurban network in the periphery. Consequently, the model introduces the concept of coupled networks to define the interrelations between two transit services and the park-and-ride facilities. The variables of density of park-and-ride stations, spacings among corridors and operating headways, control the design of the entire system. Moreover, the model is adaptive to diverse cities with different geographical constraints (e.g. sea or mountain boundaries).

城市和城际交通网络与停车换乘系统的耦合设计：巴塞罗那的分析公式和案例研究


本研究提出了一个由停车换乘设施支持的城市交通网络和城际交通网络耦合设计的分析模型。前者网络促进了大都市区中心的移动性，而城际服务则满足了来自停电换乘分散的大都市郊区的向心连接。系统的这三个组件是相互关联的。这两个网络在中心城市的主要走廊共享公共换乘站，而停车换乘是外围城际网络的接入点。因此，该模型引入了耦合网络的概念来定义两种公交服务和停车换乘设施之间的相互关系。停车换乘站的密度、走廊之间的间距和运营间隔等变量控制着整个系统的设计。此外，该模型可以适应具有不同地理限制（例如海洋或山脉边界）的不同城市。
