Urban public transport is a sustainable transportation strategy. Promoting public transport is an important means of urban transport sustainable development. Reasonable operation scheduling can increase the attractiveness of public transit systems and be conducive to the sustainability of transportation systems. Setting headways on a bus route is the key work of bus scheduling. For the refined management requirements of bus scheduling, this paper comprehensively considers the influence of three uncertainties on the bus route headway: passenger demand elasticity, which is an elasticity with respect to the supply of service, the randomness of the bus travel time between bus stops, and the abandoned passengers flow. A bus route headway allocation model is established. Considering the attractiveness of bus traveling and the interests of passengers, the objective functions are the maximum number of passengers waiting for the bus at each stop and the minimum number of passengers who fail to board. An enumeration combining a recursive algorithm under Monte Carlo random simulation conditions is designed to solve the problem. A comparison of the optimal bus departure interval (headway of the origin stop) under different conditions is studied using a numerical case. Under the same conditions, the results show that the model proposed in this paper can reduce the passengers waiting time and attract more passengers traveling by bus and it also meets the goal of sustainable public transport well. These findings are significant references for optimizing bus operations considering these uncertain factors.

This study proposes a framework to analyze public discourse in Twitter to understand the impacts of COVID-19 on transport modes and mobility behavior. It also identifies reopening challenges and potential reopening strategies that are discussed by the public. First, the study collects 15,776 tweets that relate to personal opinions on transportation services posted between May 15 and June 15, 2020. Next, it applies text mining and topic modeling techniques to the tweets to determine the prominent themes, terms, and topics in those discussions to understand public feelings, behavior, and broader sentiments about the changes brought about by COVID-19 on transportation systems. Results reveal that people are avoiding public transport and shifting to using private car, bicycle, or walking. Bicycle sales have increased remarkably but car sales have declined. Cycling and walking, telecommuting, and online schools are identified as possible solutions to COVID-19 mobility problems and to reduce car usage with an aim to tackle traffic congestion in the post-pandemic world. People appreciated government decisions for funding allocation to public transport, and asked for the reshaping, restoring, and safe reopening of transit systems. Protecting transit workers, riders, shop customers and staff, and office employees is identified as a crucial reopening challenge, whereas mask wearing, phased reopening, and social distancing are proposed as effective reopening strategies. This framework can be used as a tool by decision makers to enable a holistic understanding of public opinions on transportation services during COVID-19 and formulate policies for a safe reopening.

Transport issues in urban centers are rising at an exponential rate and are characterized by congestion, high motorized vehicles growth, vehicular and noise pollution, road accidents and parking space constraints. Present public transport and Non-Motorized Transport (NMT) modes are inefficient and do not cater to the needs of 31.23% of urbanized population in India, which is poised to grow up to 71% by 2031 (MoUD, 2015). Lack of accessibility in public transport and NMT has compelled commuters to opt for private transport modes such as two-wheelers and cars, in order to have access to work, education and other leisure activities. The paper aims to assess the finances allocated to urban transport system in the city of Pune under the jurisdiction of Pune Municipal Corporation (PMC). The authors intend to critically review the city budget and its contribution to sustainable modes of urban transport. The key research questions are: - a) whether the budget distributes enough revenue to enhance the efficiency and accessibility of public transport modes and NMT as guided in the National Urban Transport Policy (NUTP) of 2006? b) does the local government continue to invest in temporary urban transport solutions catering to the needs of private modes of transportation? The research is based on secondary budget data of the year 2016-17 and the data so collected, has been analyzed on various financial parameters. The results show that PMC’s budget allocation is not favoring sustainable modes of transport as much as it is catering to other urban transport infrastructure and utilities. The study thereby suggests sufficient allocation of the city’s budget towards the creation of sustainable transportation. Lastly, the paper concludes with recommendation on ways of innovative financing methods to make public transport, sustainable and discusses various case studies of best practices followed globally pertaining to sustainable urban transport system.

There have been growing concerns with regards to the state public transportation systems, particularly in the cities of developing countries. Chief among these concerns has been the lack of well-coordinated, efficient, and reliable transportation systems. The city of Johannesburg, just like any other fast-growing municipality in developing and emerging economies, has not been spared with regards to incessant public transport challenges. Consequently, there have been collective efforts from both public and private stakeholders to invest immensely in both innovative rail and road transport systems in the past decade. This article sought to achieve twin objectives. First, the work identified the state of connectivity between the rapid rail transportation and rapid bus transit systems based on Geoweb 2.0 data. Second, the work visualized the level of connectivity between these two modes to develop and formulate policy frameworks in integrating public transit systems in cities of the developing world, learning from the metropolitan city of Johannesburg. A mixed-method approach consisting of spatial and quantitative aspects was used to examine the state of connectedness and the promotion of access and mobility between the two modes. The local Moran’s I index was used to compute node clusters within the public transport system. Results from the analysis demonstrated that both high-clusters and low-clusters exist in the public transportation network, which have a high degree of centrality. It was revealed that commuters navigate from these nodes/stops with relative ease due to the short walking radius. However, the work revealed that most rail networks and bus routes, as well as the stations and bus stops, are not connected and are not significant in the local Moran’s I index, thus, making it difficult for commuters to conveniently move from the Gautrain to the Rea Vaya bus. There are, therefore, gaps with regards to the sharing of infrastructure between the two public transport modes and systems.

Universal Accessibility

A new methodology for universal accessibility is proposed to identify barriers in public transport accessibility and travel experience. The methodology focuses on the travel experience of people with disabilities and people with temporary restrictions in physical mobility. The methodology not only focuses on aspects of the planning, design, and operation of public transport systems, but also emphasizes sensitive aspects of user experience, considering satisfaction and emotions. The methodology maps tavel experiences using ethnographic methods and provides a graphical depiction of the trip. This helps in identifying key elements for improving accessibility when planning, implementing, and operating public transport systems. The methodology has two parts: (i) traveling along and observing a complete and common trip of people with a permanent or temporary disability or mobility restrictions, and (ii) analyzing and observing the travel experience. The methodology was applied in Bogotá, Santiago de Chile, and Medellín. The results of the methodology allowed us to formulate policy recommendations to improve the transportation systems of these cities in the short, medium, and long term. The methodology is applicable to other transit systems.

Transit Service

Cable-propelled transit’ (CPT), in particular detachable aerial ropeways are widely employed as transportation systems in alpine areas. In recent years, these transport systems have also been increasingly used in urban areas and are no longer a niche public transportation technology (Hoffmann 2006, Alshalalfah, Shalaby, and Dale 2014). Cable cars systems compete with performance characteristics of other more common urban transport technologies and have the potential to enhance the existing transport provision in cities (O'Connor and Dale 2011). While many applications can be found as transportation systems in airport facilities, and to provide access to tourist attractions, several metropolitan areas have even incorporated gondolas and aerial tramways into their public transport networks. This paper focuses on aerial ropeway systems that operate as a mass transit service (similar to buses, BRT, LRT, etc.) and are part of the public transit systems in their respective cities. Therefore, the analysis and case studies presented in the paper concern systems that are used as a public transit service

According to the European Committee (EC) on Transport, the future road transport strategy lies in creating a strong road transport sector which is based on a well-functioning internal market, fair competition and workers’ rights, decarbonization, and use of digital technologies. Urban and suburban passenger transportation systems, according to the principles of the EC, have a key role in achieving the goal of sustainable development and sustainable transport in cities. The fare, ticketing, and payment modes have a significant impact on public urban transport systems, primarily in terms of collecting transport service fees, and represent the basic source of financing of such systems, in addition to subsidies and grants from city budgets. This paper presents the selection methodology of the optimal fare system for urban public transport, applicable for all cities with an organized public city passenger transport (PCPT) system. Based on the established criteria with respect to setting tariff limits and fare systems, passenger demand, and the enterprise organizing the transport, the tariff system was selected. The presented method is that of multi- criteria optimization of the tariff system with numerical results on the example of the City of Novi Sad.

A sustainable transportation system requires a larger contribution to public transport share in comparison to private transport. Bangkok Metropolitan, the study area, exhibits a significant transport modal alteration trend towards public transport, in line with the expansion of Bangkok Transit System (BTS) and Mass Rapid Transit (MRT) for more coverage within the metropolis along main roads along with expansion of public bus routes, which increases the seamlessness and reduces transit time. This study is important as we believe that the higher seamlessness the more urban travelers would shift to using public transport modes. This matter is considered as a pertinent urban transport problem. This study aims at understanding the level of transit seamlessness of the Bangkok public transport system.  The study was carried out by firstly measuring six factors of the regular transit process, on formal and informal transport modes used by Bangkokians. These six factors were observed along the origin and the destination of the travelers with respect to travel time, number of transit points, average transit time, comfort, and transit facilities including facilities for disables, and walking distance. A total number of 300 public transport users were selected as respondents, 50 respondents for each selected transit hub. The selection was based on convenient random sampling considering the variability of destinations and purpose of travel. Despite a different destination, the residence was set as the origin. By using Modified Quantitative Gap Analysis, based on six selected transit hubs, the study found that the seamlessness of the inter-modal transits in Bangkok exhibits a characteristics of hard transit process, particularly for disabled people, notwithstanding the continuous efforts to make the seamless transit are in place, particularly with respect to infrastructure facilities.

Main Factors

Alleviating traffic congestion and developing sustainable transportation systems in a city can be assisted by promoting environmentally friendly transportation modes such as walking, cycling, and public transport. Strategies for promoting these desirable transportation modes can be identified based on a sound understanding of how commuters choose travel modes. In this study, multi-day commuting travel mode data was used to explore factors that influenced commute mode choice. A multinomial logit model and a binary logit model were proposed to study commuter travel behavior. The results showed the following. (1) Age, gender, and marriage indirectly influence the commute mode choice; (2) The cost of travel mode has little effect on commute mode choice; (3) The probability of commute mode change mainly influences the car mode choice; (4) The number of transfer times and the distance to the nearest public transport stations are main factors that restrict commuters from choosing public transport; (5) The number of bicycles in the family and commute distance are main factors that restrict commuters from choosing cycling for commuting. Based on these findings, several potential measures are demonstrated to policymakers and transportation planners to alleviate traffic congestion and develop sustainable transportation systems.

Improving the local urban transport system’s quality is often seen as one of the critical points for the government and the local operator. An amelioration of the system can improve users’ satisfaction and attract new users while simultaneously decreasing traffic congestion and pollution. Efficient methodologies are required to achieve sustainable development regarding complex issues associated with traffic congestion and pollution. In this study, we propose using the analytic hierarchy process (AHP) grey values to overcome the limitations of the uncertainty in the classical AHP approach. The presented grey-AHP model assumes an efficient contrivance to facilitate the public transport system’s supply quality evaluation, especially when respondents are non-experts. Finally, we estimate and rank the public transport system’s supply quality criteria by adopting the proposed model for a real-world case study (Amman city, Jordan). The study’s outcome shows the effectiveness and the applicability of the developed approach for enhancing the quality of the public transport system.
