Urban (UMaaS) and rural (RMaaS) mobility as a service (MaaS): practical insights from international practitioners and experts

The concept and potential of Mobility as a Service (MaaS) has been the subject of significant debate in academia and industry for nearly a decade. There are several city-based Mobility as a Service (MaaS) pilots globally. There remains a significant lack of practitioner evidence of MaaS with the focus on city-based solutions rather than in rural and suburban areas. To that end, this paper asks four research questions to contribute to the gap in Rural MaaS (RMaaS) and Urban MaaS (UMaaS); firstly, is MaaS a mobility option for rural areas given the identified evidence in scientific literature? Secondly, how do practitioner experiences with MaaS (in all areas) differ considering factors like phraseology, geography, available modes, transportation, the origin and implementation stages? Thirdly, what practical learnings can be drawn from practitioners in the field? Fourthly, what is the future of MaaS for rural and urban areas. The research and findings are based upon grey literature and twenty semi-structured interviews with representatives from research or government organisations, public bodies, MaaS technology suppliers, transport operators and experts. Each participant discussed and contributed to the practicalities around real-world applications of MaaS in urban, regional, or rural areas. The analysis produced 2 applied tools which will be useful to practitioners interested in MaaS; a Thematic Map visualising the common matters emerging from the interviews revolving around ‘People, Policy, Practice and Pilots (4Ps); a Practical Framework for Implementing MaaS tool, which can be used by any practitioner at any stage of a MaaS project.

How can on-street parking regulations affect traffic, safety, and the environment in a cooperative, connected, and automated era?

On-street parking is a commonly used form of parking facility as part of transportation infrastructure. However, the emergence of connected and autonomous vehicles (CAVs) is expected to significantly impact parking in the future. This study aims to investigate the impacts of on-street parking regulations for CAVs on the environment, safety and mobility in mixed traffic fleets. To achieve this goal, a calibrated and validated network model of the city of Leicester, UK, was selected to test the implementation of CAVs under various deployment scenarios. The results revealed that replacing on-street parking with driving lanes, cycle lanes, and public spaces can lead to better traffic performance. Specifically, there could be a 27–30% reduction in travel time, a 43–47% reduction in delays, more than 90% in emission reduction, and a 94% reduction in traffic crashes compared to the other tested measures. Conversely, replacing on-street parking with pick-up/drop-off stations may have a less significant impact due to increased stop-and-go events when vehicles pick-up and drop-off passengers, resulting in more interruptions in the flow and increased delays. The paper provides examples of interventions that can be implemented for on-street parking during a CCAM era, along with their expected impacts in order for regional decision-makers and local authorities to draw relative policies. By replacing on-street parking with more efficient traffic measures, cities can significantly improve mobility, reduce emissions, and enhance safety.

How long do transport infrastructure last: evidences from Norwegian roads and rail network

How long will transport infrastructure generate benefits for the society (the appraisal period) is an essential assumption in transport appraisals. However, there are considerable differences in the recommended appraisal periods used in cost–benefit analysis between countries. In this paper, we therefore examine how long transport infrastructure was used in the past before it was replaced, closed, or substantially improved. We label this period the ex-post appraisal period. The study considers rail and roads in Norway and analyses how long they were used using the statistical technique survival analysis. The results show that motorways build in the 1960s was used around 40?years before being upgraded, while most of railroad infrastructure have lasted more than 100?years. If these results are applicable for the future use it may indicate that the use of long appraisal periods (more than 50?years) in some countries could be optimistic for roads and rather conservative for railroads.

Urban mobility in the future: text analysis of mobility plans

Sustainable Urban Mobility Plans (SUMPs) or similar documents from 17 European capitals (published between 2010 and 2021) and the European SUMP guidelines have been analysed to understand how cities shape mobility and their transport systems. Text analysis is applied to identify development tendencies in a time- and cost-effective manner, without relying on traditional deep semantic analysis techniques. In addition to traditional statistical indicators, we introduce Category Term Frequency (CTF) as a new measure in text analysis. CTF reveals the number and proportion of words belonging to the same content group, namely specific mobility-related categories. The results indicate that categories describing general aspects such as the future, general transport, environment, and society are more prominently represented compared to more forward-looking categories like automation, electromobility, and sharing. The aggregated CTF of categories describing these emerging aspects is highest in the mobility plans of Copenhagen, Helsinki, Luxembourg, and Vienna, which are considered forerunners in their implementation. In general, the analysis concludes that despite recent technological developments and new business models, the examined mobility plans barely mention terms that would imply radical changes by the 2030s. Strategic documents and, thus, urban mobility developments suggest only a slow transition towards the expected levels of sustainable and smart urban mobility. These findings may contribute to understanding and (re)considering urban and transport development strategies in Europe. Furthermore, this text analysis framework provides planners and other experts with a novel tool to identify the focal areas of mobility-related (or other) documents.

Actualizing sustainable transport: the interplay between public policy instruments and shared mobility providers’ business models

Cities around the world are trying to understand if and how to regulate urban mobility in a way that stimulates innovation and supports business while also promoting public values and accelerating a sustainability transition. Service providers are also attempting to understand how to grow and thrive as a business as they challenge existing urban mobility structures and practices via new mobility services, new uses of public space, etc. Thus, this article seeks to understand the interplay between business models and public policies and, ultimately, the implications policy instruments have on shaping conditions for sustainable urban mobility. To address these questions, a qualitative approach is utilized, comprising case studies of two ‘new mobility’ service providers (Bolt and Tier) operating in three Northern European cities (Oslo, Stockholm, and Berlin) including interviews with these companies and local public actors. Findings show that the business models are influenced by legitimization on the national level, the local authorities’ and service providers’ approaches, and policy instruments related to the right to operate, including caps, geographic coverage, parking, geofencing, and data sharing. Utilizing business models and multi-level perspectives, the findings are discussed in relation to actualizing sustainable transport, e.g. interdependencies, goal alignment, and temporal and spatial considerations. The authors emphasize the importance of learning by doing, policy mixes (versus instruments), and purpose-driven collaboration among stakeholders.

A scoping review on the conceptualisation and impacts of new mobility services

In the course of major societal developments such as digitalisation and increasing urbanisation, various forms of so-called new mobility services have emerged. Various disciplines are engaged in understanding these services. However, what is still missing is a comprehensive understanding of what the umbrella term new mobility services means beyond a loosely used catch-all term. This article provides an interdisciplinary overview of the concept of new mobility services and their respective impacts on mobility landscapes. These aspects are summarised using a scoping review approach by examining a total of 98 publications. Our results show that the term new mobility services is indeed an umbrella term for different mobility concepts that are conceptualised differently and whose impacts on mobility landscapes are manifold. However, by applying elements of formal concept analysis, we can identify several key characteristics that define the lowest common denominator for services to be classified as new mobility services.

Why do we rely on cars? Car dependence assessment and dimensions from a systematic literature review

“Car dependence” emerges as an academic concept supported by decades of multidisciplinary research, which aims to understand the factors that drive car-based choices. The variety of approaches and indicators used to interpret this phenomenon underscores its multidimensionality and highlights the necessity for a comprehensive framework to define and operationalise it. This paper contributes to this goal by conducting a systematic literature review that examines the indicators, associations, and meanings used by research in defining and quantifying car dependence. Results show that car dependence has been mainly studied considering transport demand, despite criticisms pointing out to the need of including accessibility and subjective perceptions as well. As a consequence, the paper proposes a holistic approach to the term car dependence by proposing six dimensions covering the full spectrum of the concept as presented in the academic literature. The findings also suggest to move towards harmonising measures of the concept, which would facilitate the development of policies and the assessment of their effectiveness.

Stability assessment of railway trackwork scheduling in Sweden

Ensuring the reliability of railway transportation is heavily dependent on the quality of its infrastructure. In this regard, renewal and maintenance of the railway track infrastructure, referred to as trackwork, play a vital role. However, trackwork execution requires temporary capacity restrictions for train traffic. Therefore, harmonising the train and maintenance schedules is critical but challenging to accomplish when one is frequently changing. This paper explores and models the nature of trackwork schedule instability at the tactical level of the scheduling process. We analyse data from one year of trackwork rolling horizon plans, focusing on weekly changes at eight key trackwork locations across Sweden’s railway network. Our study considers various factors that may affect schedule stability, such as track type, location, time of day, train traffic intensity, and the type of prevailing traffic. We find that schedule instability increases as the rolling horizon plan approaches its end. The regression analysis reveals that the most significant predictors of changes in trackwork schedules include previous changes, track type (single vs. double), work location (at station vs. between stations), and the timing of trackwork (daytime vs. nighttime and month). These provide insights to trackwork planners in making informed and proactive decisions about trackwork timeslot allocation.

Projecting traffic flows for road-based passenger transport in Europe for the analysis of climate impact

Road-based transport is a significant contributor to global transport emissions of greenhouse gases and local pollutants, thus contributing to the environmental impact of the mobility of people and goods. In order to develop strategies to mitigate this impact, it is necessary to build reliable emission inventories that include sector-specific emissions. Furthermore, the methods for creating these inventories should be applicable for forecasts and scenario calculations to facilitate the evaluation of pathways towards a more sustainable transport system. The study at hand proposes a model-based framework to predict travel demand and its spatial distribution for a bottom-up calculation of road transport emissions in Europe. With this framework, it is possible to calculate emissions based on the road network structure, traffic flows and vehicle types. In order to demonstrate the applicability of the framework for scenario calculations, it is applied to three exemplary scenarios where population data is modified. With the developed methodology, a tool for the large-scale assessment of emissions from road transport is provided, which is able to simulate the impact of socio-economic and economic changes on these emissions.

Ride2Rail: integrating ridesharing to increase the attractiveness of rail travel

Shared travel offers an important way to increase the accessibility of rail services. However, providing an integrated shared travel capability for rail travel is both a conceptual and technical challenge. This paper presents an overview of Ride2Rail, enabling ‘Easy use for all’ of rail through ridesharing as part of a multimodal journey. Ride2Rail has the overall objective of developing intelligent multimodal mobility, by facilitating the efficient combination of flexible and crowdsourced transport services, such as ridesharing, with scheduled transport. A requirements activity has set out the travel behaviour and system requirements for Ride2Rail. Development activities have covered the technical implementation of Ride2Rail, involving both development of the Ride2Rail functionalities and the Ride2Rail Driver Companion application, integrated within the wider Shift2Rail ecosystem. Demonstration activities have involved the preparation, implementation, execution and monitoring of Ride2Rail at four demonstration sites. This paper outlines the overall approach and findings of the Ride2Rail. This demonstrates the technical feasibility of integrating shared travel, including the architecture for a shared ride capability that can be readily integrated into pre-existing Mobility as a Service (MaaS) platform. Additionally, the paper reports positive user attitudes to this kind of shared travel, within the context of multimodal trips.
