Transformation of Urban Public Transport Systems in the Global South

Robustness studies on integrated urban public transport networks have attracted growing attention in recent years due to the significant influence on the overall performance of urban transport system. In this paper, topological properties and robustness of a bus–subway coupled network in Beijing, composed of both bus and subway networks as well as their interactions, are analyzed. Three new models depicting cascading failure processes on the coupled network are proposed based on an existing binary influence modeling approach. Simulation results show that the proposed models are more accurate than the existing method in reflecting actual passenger flow redistribution in the cascading failure process. Moreover, the traffic load influence between nodes also plays a vital role in the robustness of the network. The proposed models and derived results can be utilized to improve the robustness of integrated urban public transport systems in traffic planning.

The City

Some small- and medium-sized Global South cities have unsustainable transport systems and no information to plan interventions in addition to having limited resources for data collection. This study proposes a method to understand Public Transport (PT) ridership in cities of these characteristics, based on previous studies and by analysing available indicators related to Manheim’s macro-variables, to identify their influence on the PT ridership. The method was applied in the city of Mexicali, Mexico. The results help to understand the causes of the low PT ridership and have implications for achieving sustainable urban mobility in the city. Findings reveal that mobility planning in Mexicali has been occurring without properly considering activity system related variables, so it is necessary to integrate urban and transport administration. Moreover, to increase PT demand in Mexicali, mobility strategies to discourage the use of private cars are necessary. The proposed method can be applied in other cities of the Global South with characteristics similar to the case study to understand the causes of PT ridership, so these can be considered by the agencies responsible for the planning of the city’s transportation system to promote a sustainable urban mobility.

Intelligent Transport Systems (ITS) are a set of tools that enable better and more efficient use of existing road infrastructure. They support the operation of transport systems in selected areas. ITS services are not only related to the improvement of cars traffic conditions but also to the functioning of urban public transport in the area of their impact. Thanks to the available ITS functions, supervision over the functioning of urban public transport has become easier and allows to achieve the intended effects in the form of increasing the importance of urban public transport (UPT) in transport systems of cities and agglomerations. Establishing transport priorities for UPT vehicles, closing streets for cars, supervising the movement of UPT vehicles, dynamic passenger information systems or immediate response to emergency situations is one of many available ITS functions in public transport. The article presents an analysis of the functioning of selected ITS services supporting the functioning of urban public transport in selected areas of the Silesian Voivodeship.
