Technological innovation in the mobility and transport sphere is still strongly aimed at vehicle- or infrastructure-based systems. Actual user needs in regard to accessibility and usability of the links between different transportation modes are usually addressed by standardized planning processes. In a row of four consecutive Austrian research projects, every element in the chain of intermodal routes was addressed, starting from the user-centered features of public transport stops in both urban and rural transport systems, to the planning tasks involved in providing demand-driven public transport. The current iteration focuses on establishing a typology of intermodal mobility hubs, including a differentiated view of the potential users of a multimodal transport system and their respective needs at the station.

Multimodal Transport

Background: In a world where every municipality is pursuing the goals of more sustainable mobility, bicycles play a fundamental role in getting rid of private cars and travelling by an eco-friendly mode of transport. Additionally, private and shared bikes can be used as a feeder transit system, solving the problem of the first- and last-mile trips. Thanks to GIS (Geographic Information System) software, it is possible to evaluate the effectiveness of such a sustainable means of transport in future users’ modal choice. Methods: Running an accessibility analysis of cycling and rail transport services, the potential mobility demand attracted by these services and the possible multimodality between bicycle and rail transport systems can be assessed. Moreover, thanks to a modal choice model calibrated for high school students, it could be verified if students will be really motivated to adopt this solution for their home-to-school trips. Results: The GIS-based analysis showed that almost half of the active population in the study area might potentially abandon the use of their private car in favour of a bike and its combination with public transport systems; furthermore, the percentage of the students of one high school of Palermo, the Einstein High School, sharply increases from 1.5% up to 10.1%, thanks also to the combination with the rail transport service. Conclusions: The GIS-based methodology shows that multimodal transport can be an effective way to pursue a more sustainable mobility in cities and efficiently connect suburbs with low-frequent public transport services to the main public transport nodes.

Transport systems are major emitters of greenhouse gases, which makes environmental sustainability of any transport a crucial issue. Another issue is the lack of a systematic approach to the modeling and implementation of public transport systems. Finally, there are problems with the human interfaces to public transport systems, which do not encourage, and many do not allow, comfortable and simple interaction with the system. In this chapter, the authors discuss their solutions for these problems, explaining how to cover the existing gaps in a methodological and systematic way. The main contribution of this chapter is a model of an on-demand transport system that covers all the points mentioned above and focuses on spatial planning and optimizations including environmental issues in transport planning.

Speed Up

There is a large number of tools for the simulation of traffic and routes in public transport systems. These use different simulation models (macroscopic, microscopic, and mesoscopic). Unfortunately, these simulation tools are limited when simulating a complete public transport system, which includes all its buses and routes (up to 270 for the London Underground). The processing times for these type of simulations increase in an unmanageable way since all the relevant variables that are required to simulate consistently and reliably the system behavior must be included. In this paper, we present a new simulation model for public transport routes’ simulation called Masivo. It runs the public transport stops’ operations in OpenCL work items concurrently, using a multi-core high performance platform. The performance results of Masivo show a speed-up factor of 10.2 compared with the simulator model running with one compute unit and a speed-up factor of 278 times faster than the validation simulator. The real-time factor achieved was 3050 times faster than the 10 h simulated duration, for a public transport system of 300 stops, 2400 buses, and 456,997 passengers.

Last Mile

Bicycle Sharing Systems (BSSs) are exponentially increasing in the urban mobility sector. They are traditionally conceived as a last-mile complement to the public transport system. In this paper, we demonstrate that BSSs can be seen as a public transport system in their own right. To do so, we build a mathematical framework for the classification of BSS trips. Using trajectory information, we create the trip index, which characterizes the intrinsic purpose of the use of BSS as transport or leisure. The construction of the trip index required a specific analysis of the BSS shortest path, which cannot be directly calculated from the topology of the network given that cyclists can find shortcuts through traffic lights, pedestrian crossings, etc. to reduce the overall traveled distance. Adding a layer of complication to the problem, these shortcuts have a non-trivial existence in terms of being intermittent, or short lived. We applied the proposed methodology to empirical data from BiciMAD, the public BSS in Madrid (Spain). The obtained results show that the trip index correctly determines transport and leisure categories, which exhibit distinct statistical and operational features. Finally, we inferred the underlying BSS public transport network and show the fundamental trajectories traveled by users. Based on this analysis, we conclude that 90.60% of BiciMAD’s use fall in the category of transport, which demonstrates our first statement.

Abstract Models of multimodal cyclic processes, i.e. processes realized with synergic utilization of various local and cyclic acting processes, play a determining role in an evaluation of functioning efficiency inter alia in public transport systems, passengers movement, cargo transport, data and energy transmission etc. We assume that the structure of a system determines repertoire of its behaviors. The paper presents a constraints satisfaction problem, which solving enables an evaluation of potential behaviors of the system of concurrently interacting local cyclic processes. Consequently, it is possible to plan and schedule the multimodal processes realized in that system. The constraints satisfaction problem, enabling the search for the structure of inter-position transport system and guaranteeing realization of assumed schedule of multi-assortment production was formulated for a declarative model of the multimodal transportation processes system. The attached calculation example illustrates the computational efficiency of the proposed approach.

Public Transport System

The Arabian Gulf cities are growing. The gulf cooperation council states (GCCs) are among the richest and most urbanized in the world. As a major focus on sustainable development of cities, sustainable transportation acts to diminish the city’s energy consumption by providing a public transport system that has greater ecological obligation and societal justice. The study’s significance is to figure out the challenges in the sector of public transport in the city of Muscat. The wide spread of mass transportation plays a significant role in reducing the exhaustion of energy. Also, it contributes to make a better living experience.  Provision of sustainable public transport will prevent the increasing number of motor cars and equally accompanied environmental pollution and traffic congestion. The study is based on an in-depth quantitative and qualitative research method to explore the hindrances that are encountered in the way of building sustainable infrastructure of public transport. The findings of the study revealed that public transport system face real challenges in Gulf region, particularly in Muscat. It indicated that for the well-being of Gulf society, the use of public transportation was encouraged and most of the population have their own cars. In addition to it, cultural and social preservations are raised, mainly by the people that act against the operation of public transport system. Due to the substantial effect of clean  and  sustainable transportation  on energy consumption levels, recent years have been marked with a notable trend  towards  sustainable and  low carbon systems, particularly the mass  transportation ones.

The article deals with the main factors influencing the formation and development of the multimodal transport system of Ukraine in modern conditions. The object of the research is the process of formation of the domestic multimodal transport system. The purpose of the work is to determine the necessary measures for the formation of the multimodal transport system of Ukraine. In Ukraine, multimodal transportation is at the initial stage of development. Among the main factors hindering the formation and development of multimodal transport systems in Ukraine, is the imperfection of regulatory legal regulation of multimodal transport issues; absence of own environmentally friendly rolling stock of different types of transport, especially on road transport, which carries out transportation on long distances; imbalance between levels of capacity of objects of multimodal transport infrastructure and volumes of cargo flows; high risks of multimodal carriers at significant distances with two or more modes of transport; political situation in Ukraine; information provision of all parts of the multimodal logistics chain, etc. To solve these problems, measures have been proposed that will allow the formation and development of the multimodal transport system of Ukraine. The results of the work can be applied for the formation of a national multimodal transport system. Foreseeable assumptions about the development of the research object - the study of the components of the multimodal transport system.

Social Inequities

This chapter focuses on India’s public transport system. If cities are democratic laboratories that nurture free and equal motion, then India fails the test every day. In Mumbai, for example, up to sixteen people can find themselves packed into a one-square-metre space inside a carriage during peak hours as Indian Railways fails to provide enough trains and coaches to the financial capital’s arterial rail network. Travelling like animals, risking their lives for livelihood, has been the lot of Mumbai’s daily commuters for as long as they can remember. Away from the cities, where 70 per cent of India lives, the picture is even bleaker, with virtually no state-run public transport system—buses or trains. The daily indignities and inconveniences of travelling prevents citizens from freely accessing goods, services, and social networks that are key to the pursuit of their chosen life strategies. By hindering everyday mobility, hazardous and insufficient transport options have the anti-democratic effect of perpetuating social inequities and dispersing communities into isolated silos that prevent collective assembly, deliberation, and action. Other than dilapidated or non-existent public transport systems, elitist policies, and poor government oversight hinder movement—and democracy—in various other ways.

Abstract A policy instrument promoting a free fare public transport policy (FFPT) has recently been put into practice in 66 municipalities across Poland. By contributing to the academic debate on the concept of FFPT (e.g. Kębłowski 2019), the main goal of this paper is to create a typology of the schemes where FFPT is in operation in Poland based on analyses of a geographical mapping of these projects. This study analyses how different municipalities are implementing the concept in order to define a typology of FFTP projects and to understand how the development landscape of the urban transport system is changing in the light of free fare transport policies, topics which are not fully covered in the academic literature. The findings confirm that there is a new dynamic in the development of urban transport systems and permit the identification of key characteristics of this trend. Besides the typology of implementation of FFPT, the study also presents an up-to-date inventory of FFPT projects with the key characteristic features of each system. Although the study does not provide specific recommendations regarding the introduction of a FFPT policy, it represents a good starting point for future and more detailed studies. Such studies are necessary in order to understand the role of FFPT not only in the context of the development of a given transport system, its impact on modal split, and travel behaviour, but also to uncover the different politics which lie behind them.

The coronavirus pandemic has affected everyday life to a significant degree. The transport sector is no exception, with mobility restrictions and social distancing affecting the operation of transport systems. This research attempts to examine the effect of the pandemic on the users of the public transport system of London through analyzing tweets before (2019) and during (2020) the outbreak. For the needs of the research, we initially assess the sentiment expressed by users using the SentiStrength tool. In total, almost 250,000 tweets were collected and analyzed, equally distributed between the two years. Afterward, by examining the word clouds of the tweets expressing negative sentiment and by applying the latent Dirichlet allocation method, we investigate the most prevalent topics in both analysis periods. Results indicate an increase in negative sentiment on dates when stricter restrictions against the pandemic were imposed. Furthermore, topic analysis results highlight that although users focused on the operational conditions of the public transport network during the pre-pandemic period, they tend to refer more to the effect of the pandemic on public transport during the outbreak. Additionally, according to correlations between ridership data and the frequency of pandemic-related terms, we found that during 2020, public transport demand was decreased while tweets with negative sentiment were being increased at the same time.
