The effects of operational characteristics of the public transport system on the performance of the urban network traffic flow and the public transport system have been widely investigated at the local level. However, to the best of authors' knowledge, there is no attempt to investigate these characteristics at the network level. This study bridges this gap through the notion of network macroscopic fundamental diagram. In particular, the effects of the bus stop location (i.e. far-side and near-side) and berth number are discussed at the network level through simulating different scenarios in the central business district of the city of Christchurch, New Zealand. In consistent with the local level studies, the outputs show that the far-side bus stops result in better network performance (i.e. larger capacity and critical density range) and a lower median for the network average delay of car traffic. The near-side bus stops instead lead to a lower median for the public transport system. The results reveal that increasing the berth number improves the network capacity and median of the network average delay for both modes. Finally, the impacts of the combination of the far-side and near-side bus stop on network performance have been discussed.

公交车站位置和泊位数量对城市网络交通性能的影响

在地方层面，已经广泛研究了公共交通系统的运行特性对城市网络交通流和公共交通系统性能的影响。但是，据作者所知，没有尝试在网络级别研究这些特征。本研究通过网络宏观基础图的概念弥合了这一差距。特别是，通过模拟新西兰基督城中央商务区的不同场景，在网络级别上讨论了公交车站位置（远侧和近侧）和泊位数量的影响。与本地研究一致，输出结果表明，远端的巴士站可带来更好的网络性能（即 更大的容量和更高的临界密度范围）以及更低的网络平均车流量延迟中位数。相反，靠近公交车站的地方导致公共交通系统的中位数降低。结果表明，增加泊位数量可以提高两种模式的网络容量和网络平均延迟的中位数。最后，讨论了远端总线站和近端总线站的组合对网络性能的影响。
