  • Survey of charging management and infrastructure planning for electrified
           demand-responsive transport systems: Methodologies and recent developments
           

    • Abstract: Abstract The accelerated electrification of transport systems with EVs has brought new challenges for charging scheduling, fleet management, and charging infrastructure location and configuration planning. In this review, we have provided a systematic review of the recent development in strategic, tactical, and operational decisions for demand responsive transport system planning using electric vehicles (EV-DRT). We have summarized recent developments in mathematical modeling approaches by focusing on the problems of dynamic EV-DRT optimization, fleet sizing, and charging infrastructure planning. A list of existing open-access datasets, numerical test instances, and software are provided for future research in EV-DRT and related problems. Current research gaps are identified and future research directions are discussed.

  • Value of travel time by road type

    • Abstract: Abstract Travel time is less costly if it is comfortable or can be used productively. One could hence argue that the value of travel time (VTT) of car travellers in economic appraisal should be differentiated by road type, reflecting differences in road quality. We explain the theoretical foundation for such a differentiation, review the relevant literature and show the results of an empirical case study based on actual route choice of highway drivers in Norway. We find little existing literature discussing the link between road type and VTT, but closely related findings suggest that that the impact on VTT could be substantial. Our empirical case study also suggests that the VTT is lower on higher quality road types. Applying this to economic appraisal would imply higher user benefits of road projects that improve road quality.

  • Shared mobility services: an accessibility assessment from the perspective
           of people with disabilities

    • Abstract: Introduction Shared on-demand mobility services emerge at a fast pace, changing the landscape of public transport. However, shared mobility services are largely designed without considering the access needs of people with disabilities, putting these passengers at risk of exclusion. Recognising that accessibility is best addressed at the design stage and through direct participation of persons with disabilities, the objective of this study was to explore disabled users’ views on the following emerging shared mobility services: (a) ride pooling, (b) microtransit, (c) motorbike taxis, (d) robotaxis, (f) e-scooter sharing, and (g) bike sharing. Methodolgy Using an online mobility survey, we sampled disabled users’ (1) views on accessibility, (2) use intention, and (3) suggestions for improving accessibility. The results reflect the responses of 553 individuals with different types of disabilities from 21 European countries. Results Projected accessibility and use intention were greatest for microtransit, robotaxis, and ride pooling across different disabilities. In contrast, motorbike taxis, e-scooter sharing, and bike sharing were viewed as least accessible and least attractive to use, especially by persons with physical, visual, and multiple disabilities. Despite differences in projected accessibility, none of the shared mobility services would fulfil the access needs of disabled persons in their current form. Suggestions for increasing the accessibility of these services included (a) an ondemand door-to-door service, (b) an accessible booking app, (c) real-time travel information, and (d) the necessity of accommodating wheelchairs. Conclusions Our findings highlight the need for improving both vehicles and service designs to cater for the access needs of persons with disabilities and provide policymakers with recommendations for the design of accessible mobility solutions.

  • Developing disruptive mobility scenarios for rural areas. Participatory
           mobility scenario building in a Belgian village for the year 2050

    • Abstract: Background Historically, quantitative forecasting methods have been used in transport planning. As forecasts can be unreliable to plan for the medium- and long-term, scenario building has recently been increasingly used. However, scenario building methods often fail to take disruptions and wild cards into account, i.e., low probability but high impact events. When unaccounted for, wild card events, like the COVID-19 pandemic, lower the efficacy of scenario building in policy making, as these events may completely disturb the developed scenarios of the future. Methods In this paper, we develop and apply a creative and participatory methodology to develop visions and disrupted scenarios for rural mobility. Our research was carried out in the Belgian village of Oetingen, where inhabitants developed more resilient views of the future by creating disrupted mobility scenarios and a preferred mobility vision for their village for the year 2050 in a participatory scenario building exercise. Wild cards related to mobility were collected from mobility experts and inhabitants in three workshops. Inhabitants were engaged to define their mobility vision on a postcard that was distributed to all houses in the village as well as on a project website. Respondents were invited for a follow-up interview in which their preferred mobility vision was subjected to the wild cards, and participants described how these wild cards would change their preferred vision. As children tend to have more creative ideas, they were engaged via workshops at school. Results This process resulted in mobility scenarios for the village for the year 2050 based on the different wild cards, as well as an overall desired vision. We found that the use of wild cards did not significantly change the scenarios when compared to the vision, although it did make the interviewees step outside of their comfort zones. We also found that the citizens did not have more original and less path-dependent ideas in developing wild cards when compared to experts. Lastly, we found that children have many outside-of-the-box suggestions when it comes to the future. Although some of their ideas can be judged as impractical by today’s standards, many ideas had an indirect implication for mobility in the village and gave insights into children’s priorities, as potential future residents of the village.

  • Framework for connecting the mobility challenges in low density areas to
           smart mobility solutions: the case study of Estonian municipalities

    • Abstract: Abstract Innovation in mobility is proceeding at fast pace, the future disrupting technologies ranging from automation and connectivity to micro-mobility and electric propulsion. This research effort is justified by the impressive array of challenges that urban centres will face in the following decades, such as ageing population, urbanization and pollution. It is therefore understandable why the concept of Smart City is being researched and the major cities around the world are already carrying out trials for Smart Mobility Solutions. Still this trend, as many others, is not evenly spread but follows the urban/rural divide characterizing many of the current socio-economical phenomena. This paper, following the principles of responsible innovation, tries to build the case for a renewed research effort about smart mobility in low density areas. This is accomplished by presenting the results of a wide surveying effort across Estonian municipalities, focusing on the outputs from rural and small suburban centres. The results report what are the main mobility challenges across the region and what hindering factors are preventing envisioned solutions. Finally, the paper ties the identified mobility challenges to available Smart Mobility Solutions that arose from the surveying activity and from literature, assessing both feasibility and transferability.

  • Route choice estimation in rail transit systems using smart card data:
           handling vehicle schedule and walking time uncertainties

    • Abstract: Abstract Several cities around the world rely on urban rail transit systems composed of interconnected lines, serving massive numbers of passengers on a daily basis. Accessing the location of passengers is essential to ensure the efficient and safe operation and planning of these systems. However, passenger route choices between origin and destination pairs are variable, depending on the subjective perception of travel and waiting times, required transfers, convenience factors, and on-site vehicle arrivals. This work proposes a robust methodology to estimate passenger route choices based only on automated fare collection data, i.e. without privacy-invasive sensors and monitoring devices. Unlike previous approaches, our method does not require precise train timetable information or prior route choice models, and is robust to unforeseen operational events like malfunctions and delays. Train arrival times are inferred from passenger volume spikes at the exit gates, and the likelihood of eligible routes per passenger estimated based on the alignment between vehicle location and the passenger timings of entrance and exit. Applying this approach to automated fare collection data in Lisbon, we find that while in most cases passengers preferred the route with the least transfers, there were a significant number of cases where the shorter distance was preferred. Our findings are valuable for decision support among rail operators in various aspects such as passenger traffic bottleneck resolution, train allocation and scheduling, and placement of services.

  • Modelling connection trips to long-distance travel

    • Abstract: Abstract Connection trips is often an important part of long-distance travel, especially for air travel. Models of long-distance travel would therefore benefit from a more detailed representation of the connection part. In this paper it is however shown that most models of connection trips are stand-alone models not integrated with the model for main mode. Only a handful models that integrate connection trip modelling into a large-scale transport model for long-distance travel are found. The connection trip models are classified into different types using a typology developed within the paper. The typology identifies nine model types that differ in how access/egress mode choice and terminal choice are handled. The scarce literature on connection trip modelling within large-scale transport modelling systems call for more research regarding detailed representation of access/egress mode choice and terminal choice, especially regarding the trade-off between model complexity and detailed representation, as well as whether the detailed representation of connection trips should primarily be conducted within the public transport network assignment or on the demand modelling side.

  • Barriers to change in urban freight systems: a systematic literature
           review

    • Abstract: Purpose The purpose of this systematic literature review is to contribute to the knowledge about barriers to change in urban freight systems and to support managed changes toward more sustainable urban freight systems. Method This paper is based on a systematic review covering 93 peer-reviewed journal articles. The study was designed to advance earlier research in this area by providing a system perspective on barriers to development in urban freight systems. The theoretical knowledge about these barriers was analyzed and synthesized, the relationships between barriers explored, and the insights developed into a model of understanding of managed change processes in urban freight systems. Findings From a system perspective 11 categories of barriers to change in urban freight systems were identified and characterized. The barriers are, in different ways, related both to each other and to a managed change process for sustainable development of urban freight systems. A model for understanding categories of barriers and their connection to managed change processes in urban freight systems is proposed in this paper. The model consists of three groups of barriers within the process, and two groups in the system context, which should be addressed with different priorities in a managed change process. The study identifies several future research options. Future research could support the development of sustainable urban freight systems by providing insights into change process governance, potentially by combining theory from areas like organization, systems, and networks with the system perspective on urban freight systems. Research on non-European urban freight systems could increase the scholarly insights about contextual impact on barriers and change processes. Future studies could also explore methods to mitigate identified barriers, especially in the areas of cooperation, organization, politics, knowledge, and the first mover disadvantage. Finally, future research should continue to develop the model of the managed change process for urban freight systems and its use in supporting sustainable development of these systems.

  • Assessing robustness in multimodal transportation systems: a case study in
           Lisbon

    • Abstract: Introduction Worldwide public transport systems are exposed to disruptions caused by malfunctions, accidents, maintenance, reduced fleet, and disasters, compromising mobility. Transport networks’ multimodal planning and management can be explored to increase their robustness against these events. In this context, this research paper proposes and empirically compares methods to assess the robustness of a multimodal transport network, looking at aspects regarding the single-mode and multimodal network topology. Materials and Methods We hypothesize that the appropriate multilayered and traffic sensitive modeling of a multimodal transport network can help characterize robustness and further unravel vulnerabilities related to the integration of different transport modes. Using metric-based targeting, we evaluate how the network decreases performance when simulating failures on stations and pathways using different scenarios. The following six extraction strategies for nodes and edges were used in the simulation: Random removal; Initial Degree removal; Initial Betweenness removal; Recalculate Degree removal; Recalculate Betweenness removal; and Multimodal Hubs removal. Lisbon’s public transport is used as a case study and is modeled as a multiplex network integrating eight different modes of transport. Proposing a novel normalized version of assessing the impact of failures, we were able to compare side by side the robustness of each modality layer, regardless of their size. Lastly, we simulate cascading events such as the breakdown of an entire transportation line. Conclusions Using different ways to induce failures in the network, we observe that to leave all nodes completely disconnected, we would need to remove about half the network nodes, highlighting the robustness of the Lisbon public transport network. Comparing different failure scenarios, methods that rely on recalculating network metrics yield a higher impact on the network robustness assessment. The impact of different events is quantified, showing that failures in stations are generally more dangerous than in pathways and offering views on the consequences of deactivating particular network modules. Overall, the results of this study allow decision-makers to gain further understanding of the topological vulnerabilities of a transportation network.

  • The periodicity and initial evolution of micro-mobility systems: a case
           study of the docked bike-sharing system in New York City, USA

    • Abstract: Objectives This study developed an analytical framework that aims at understanding the evolutionary processes of a micro-mobility system (for example, bike-sharing), which offers insights into the transforming nature of a city transport system. Methods Firstly, the framework applied a Gaussian Mixture Model to examine the long-term fluctuations of travel demands. Secondly, it investigated the growth trajectories of service points via exponential and logistic growth models. Cumulative connections with other points represented the growth of a service location. An eigendecomposition approach was used to uncover the hidden structures behind the growth curves. Results This framework was applied in the docked bike-sharing program in New York City, USA. The results show that there existed periodic patterns of travel demands in the long term. The majority of stations grew rapidly after they began to operate. However, the temporal signatures of stations’ growth displayed some variations across different locations. Conclusion This proposed workflow can be employed in other cities with similar context to better investigate how micro-mobility systems evolve.

  • The time cost of saving money: detouring and connecting time losses in the
           virtually interlined European airport network

    • Abstract: Abstract Virtual interlining, the use of actively marketed self-connecting flight itineraries, is often assumed to be a money-saving air travel strategy. Earlier research on this topic broadly confirmed the money-saving character of virtual interlining, but to date non-monetary costs associated with this price advantage have not yet been systematically examined. In this paper, we address this lacuna by juxtaposing the price advantage of virtual interlining with the potential time costs for the case of indirect flight itineraries in the European airport network. Focusing on those markets where the cheapest virtually interlined itinerary renders a price advantage over its indirect traditional counterpart, we analyse the time cost from two complementary perspectives: (1) connecting time and (2) detour factor. To this end, we query Kiwi.com’s Tequila platform to obtain data on all available flight itineraries in the first week of August, October and December 2019. Based on a series of sign tests, we reveal the time costs of saving money: while virtually interlined itineraries render a price advantage compared to their indirect traditional counterparts, they come with a significantly larger connecting time and detour factor. We reflect on possible explanations, and highlight a number of avenues for future research.

  • A nationwide mobility service guarantee for Austria: possible design
           scenarios and implications

    • Abstract: Background We present a sketch for a nationwide “Mobility Service Guarantee” (MSG) for Austria. The approach follows a new paradigm, turning away from car-centric transport policy and planning and towards the extensive provision of public transport. The approach is complemented by the provision of demand-responsive transport services and the support of vehicle sharing as well as active mobility. This combination should serve as an effective alternative option to the use of private cars. Purpose The aim of this study is to develop a tangible definition of a nationwide MSG in the Austrian context as well as possible design scenarios. Methods We took a multi-dimensional approach, using literature review to research existing concepts of mobility guarantees, analysing secondary data on current mobility behaviour and public transport provision and conducting stakeholder workshops. Results We define possible scenarios envisioning a nationwide MSG including different extents of maximum distance to public transport stops and minimum frequency. We discuss the limitations of the MSG with respect to spatial, temporal and modal coverage, as well as how such a guarantee could be embedded in the existing legal system. Conclusions We conclude that a nationwide MSG could be an important element of sustainable transport policy that should be embedded in a wider strategy of infrastructure and service design as well as demand management.

  • Autonomous vehicle impact on improving road network vulnerability

    • Abstract: Purpose This study first presents a method to identify the parameters increasing road vulnerability on a macroscopic road network model. The second part exploresthe effect size difference of the analyzed attributes on network vulnerability through the implementation of different autonomous vehicles (AVs) penetrations and automation levels. Methods The road traffic network of Budapest, Hungary on PTV VISUM is studied by adopting a passenger car unit factor procedure to simulate the effect of AVs on road saturation. Five link parameters were used: length, distance from the centre, speed, number of lanes, and number of connectors. Network vulnerability was studied by simulating a combination of road elimination process with different passenger car unit values for AVs. Results The analysis found the number of road lanes is the most significant parameter, affecting the link criticality; followed by road length and distance from the centre. The analysis of four AV scenarios with different AV penetration and level of automation showed huge effect differences ranging from 3.50% for a simple AV automation level with low AV percentage to as large to 28.53% for a fully automated fleet. Conclusions AV implementation has proved efficient in reducing the amount of travel delays in the case of road failure. Finally, it was found that the number of lanes remained the most significant influencing parameter on travel delay. The main question is to discover the effect size difference of the analyzed attributes on network vulnerability through the implementation of different AVs penetrations and automation levels.

  • Measuring spatial accessibility to urban services for older adults: an
           application to healthcare facilities in Milan

    • Abstract: Abstract This study proposes a Geographic Information Systems-based methodology to measure accessibility to urban services from the elderly perspective to support urban planning processes. Specifically, it seeks to understand and clarify how the urban environment can influence the quality of life for older adults, mostly through pedestrian and public transport networks, locations of essential urban services, and the organisation of their resources. In light of a significant demographic change, policymakers will have to promote age-friendly urban planning approaches to guarantee equal access to services and activities. We propose a methodology to measure accessibility to healthcare provision services that considers land-use and mobility features and older adults' behavioural traits. The method belongs to the family of 2SFCA—2 steps floating catchment area—which evaluate accessibility as the combination of both supply and demand of urban services. Therefore, we have introduced innovative elements to shape actual mobility opportunities for the elderly and their travel choices. The methodology was applied to Milan's city to measure accessibility to the Health Protection Agency (ATS) services, which is responsible for healthcare assistance to the elderly dwelling in the city. The outputs show that a significant share of older people (almost 40%) suffer from poor accessibility to primary health services and that they mostly live in the city periphery. Moreover, the application to a case study has shown that the methodology could identify the critical aspects needed to aid urban planning to achieve a high quality of life for elderly people.

  • Implications of COVID-19 for future travel behaviour in the rural
           periphery

    • Abstract: Background The design, management and operation of transport systems is a complex activity and this has only been exacerbated since the onset of the COVID-19 pandemic. Concern has been raised over the likelihood of the public transport sector surviving in some locations given the significant drops in patronage; this is especially so in rural environments where the existing provision was already limited. Furthermore, within the growing literature on the impact of COVID-19 on travel behaviour most of the focus is on urban areas with little documented experience of how rural travel behaviour has been impacted. Purpose This paper investigates the impact of COVID-19 on the transport sector and travel behaviour in the rural periphery. Methods Drawing on the work of the International Transport Forum (ITF) Working Group on Innovative Mobility for the Periphery, augmented by additional evidence and findings from the literature, this paper addresses three specific questions: Firstly, how COVID-19 has affected rural mobility. Secondly, how we can plan for sustainable rural transport solutions in the post-COVID world. Thirdly, the longer-term impacts of COVID-19 with implications for mobility. Results There will be substantial impacts from COVID-19 on rural societies and while the short-term impacts have been negative, in the longer-term there may be opportunity for changed mobility behaviours (including in response to modified work and activity patterns). Evidence suggests that it would seem likely that there are opportunities to foster new rural mobility solutions to support sustainable mobility (including Mobility-as-a-Service) and counter the traditionally fragmented transport base; this will be important as we learn to live with COVID-19. Conclusions While recognising the impact of changing funding priorities and the possible shift in economic activity as a result of the pandemic we conclude with suggestions for future rural transport policy.

  • Cost-effectiveness and gain-sharing scenarios for purchasing a
           blockchain-based application in the maritime supply chain

    • Abstract: Abstract Maritime supply chain (MarSC) stakeholders interact with third parties (e.g. freight forwarders, 3PLs, financial institutes, custom authorities) to facilitate the cargo flow and exchange of information, documents, or financials. Hence, MarSC stakeholders are increasingly interested in innovative technological solutions that vouch for the authenticity and/or the ownership of digital assets without the control of a central third party. Extended research is carried out to prove how applications based on the distributed ledger technology or blockchain address these requirements, yet limited research investigates their purchasing process and economic implications. This paper uses the phytosanitary certificate in an international supply chain flow as a case study where interaction between multiple stakeholders is fundamental and analyses the purchase scenarios of a blockchain-based tool. To do so, it uses a theoretical model that identifies and quantifies the costs and benefits incurred by MarSC stakeholders, formulates gain-sharing scenarios and presents the results of a sensitivity analysis to show the dependence between the data-use and the potential economic gains it generates. The results show that freight forwarders could share economic benefits with shippers or consignees to anticipate purchasing a blockchain-based tool.

  • Challenges of delivering TOD in low-density contexts: the Swedish
           experience of barriers and enablers

    • Abstract: Background Transit Oriented Development (TOD) is key to the success of public transport and for sustainable urban and regional development. Previous research has often focused on delivering TOD in urban areas with high population and building densities. This highlights the need to broaden the scope of TOD approaches to also include less densely populated areas located outside the immediate urban cores as a key concern for policy. Purpose The aim of this paper is to increase the knowledge of how to deliver TOD in such low-density contexts. Methods Three case studies of attempts at delivering TOD in sparsely populated areas in three Swedish city-regions are made. The data for the case studies consist of planning documents and 13 interviews with key stakeholders involved in the planning processes of the three cases. Results The results show that many of the barriers and enablers are rather similar to those identified in research on TOD in much more urban contexts in other parts of the world, but the relationships between them are differently nuanced in low-density contexts. The lack of clear quantified definitions of what TOD is (or is not) allows a more flexible, site-specific understanding of TOD to emerge in this context. Results It is important that a shared vision of TOD in each location is developed by the organizations involved—and such a shared vision appears to be crucial for the development to have a good chance of being delivered. Informal definitions, and individual perceptions (including those of the public) are important; and in locations that are quite “marginal” for TOD, all enablers must interact together positively for the development to have the maximum likelihood of going ahead as planned.

  • Patronage effects of off-peak service improvements in regional public
           transport

    • Abstract: Abstract The purpose of this study is to look into patronage effects of extended supply outside peak hours on regional public transport services. Previous studies have shown that the service frequency is an attribute of great importance for regional passengers, but little is known about the details regarding peak and off-peak frequencies or service hours. The present study addresses this knowledge gap, departing from the hypothesis that additional off-peak supply means more flexibility for the passengers in terms of departure time options, and possibly also a sense of security for passengers who are uncertain about the time of their (return) trips. Essentially, the added off-peak departures may attract more passengers even if they normally do not or only occasionally use the off-peak services. The patronage effects are explored through four case studies from the region of Scania in southern Sweden. The cases include regional rail and bus services where substantial improvements have been made outside peak hours, resulting in at least hourly all-day services. The results of the study provide new insights into the fundamental planning policy trade-off between maximum frequency and span of public transport services in urban peripheries and rural areas. Importantly, the results suggest that improved time coverage may lead to substantial patronage growth, and this growth is evident also during peak hours, despite unaltered peak hour frequencies. Hence, off-peak departures cannot be assessed only through patronage levels in isolated time periods, let alone on the individual departures.

  • Radio communication-based method for analysis of train driving in an ERTMS
           signaling environment

    • Abstract: Background ERTMS is an important project improving cross-border interoperability throughout Europe by a single rail signaling standard. One advantage following this development is a standardized radio signaling, which can be tracked by logging the data transfer using the ETCS protocol between Radio Block Center and train. This means that a broad spectrum of train driving can be analyzed in terms of for example driving behavior, signal planning and capacity in a new efficient way. Methods In this paper a radio-based protocol method to achieve this, is presented and applied for studying braking characteristics in terms of meeting point design. The aim was to design, apply and validate a radio-based train data collection method to enable cost-efficient and avoid time-consuming train data collections. To enable comparison between the results from the suggested radio-based method and traditional methods, a verification measurement was performed. Three different alternatives of speed calculation were validated. These were based on: Train Position Report speed; calculation of average speed based on reported train position; processed reported train position forming the average speed. The best alternative was then applied to examine deceleration towards different signal targets at single-track meeting points. Results The results from this study suggest that the ETCS Level 2 protocol is a feasible way to collect train dynamics data. The method is time saving when it comes to train driver behavior studies where several trains and drivers are needed to get significant results. Comparison with traditional GPS method suggest that the method is valid. Most promising is the alternative using processed train position.

  • Using ANPR data to create an anonymized linked open dataset on urban
           bustle

    • Abstract: Abstract ANPR cameras allow the automatic detection of vehicle license plates and are increasingly used for law enforcement. However, also statistical data generated by ANPR cameras are a potential source of urban insights. In order for this data to reach its full potential for policy-making, we research how this data can be shared in digital twins, with researchers, for a diverse set of machine learning models, and even Open Data portals. This article’s key objective is to find a way to anonymize and aggregate ANPR data in a way that it still can provide useful visualizations for local decision making. We introduce an approach to aggregate the data with geotemporal binning and publish it by combining nine existing data specifications. We implemented the approach for the city of Kortrijk (Belgium) with 43 ANPR cameras, developed the ANPR Metrics tool to generate the statistical data and dashboards on top of the data, and tested whether mobility experts from the city could deduct valuable insights. We present a couple of insights that were found as a result, as a proof that anonymized ANPR data complements their currently used traffic analysis tools, providing a valuable source for data-driven policy-making.
