Abstract [en]

Travel surveys can uncover information regarding travel behaviour, needs, and more. Collected information is utilised to make choices when reorganising or planning built environments. Over the years, methods for conducting travel surveys have changed from interviews and forms to automated travel diaries in order to monitor trips made by travellers. With the fast progression of technological advancements, new possibilities for operationalising such travel diaries can be implemented, changing from utilising mobile to wearable devices. Wearable devices are often equipped with sensors which collect continuous biometric data from sources that are not reachable from standard mobile devices. Data collected through wearable devices range from heart rate and blood pressure to temperature and perspiration. This advancement opens new possible layers of information in the collection of travel data. Such biometric data can be used to derive psychophysiological conditions related to cognitive load, which can uncover in-depth knowledge regarding stress and emotions. This paper aims to explore the possibilities of data analysis on the data collected through a software combining travel survey data, such as position and time, with heartrate, to gain knowledge of the implications of such data. The knowledge about the implications of spatial configurations can be used to create more accessible environments.

Abstract [en]

This book chapter provides an overview of the lessons learned from an automated bus deployment on a public road in Sweden and the adoption behaviour surrounding the technology. In particular, this chapter discusses different elements of users’ acceptance, willingness to use, willingness to pay for the service, and the interaction between vehicles and other road users on the given road space. Overall, the findings highlight a gap between people’s expectations on the driverless vehicles and the actual performance of the automated buses. The study also highlights the importance of allowing people to have time to learn, develop their understanding, and adjust their expectations towards the technology. This is not only for the passengers who used the service, but also for the other road users who shared the same road space. This highlights the importance of design thinking in deploying a new (public) transport service that uses new/unusual technologies.

Abstract [en]

Successful implementation of a first-/last-mile automated bus (AB) service depends on consumers' actual adoption of the service. Consumers, when decided to take an AB ride for the first time, shall rely on their expectation of the service and capabilities of the technology. After the first ride of the vehicle, their value assessments of the service are further refined based on their actual ride experiences. Whether the operators can retain the users highly depend on such assessment. Thus, it is immensely important, when investigating users' adoption behaviour of a first-/last-mile AB service, we take into account the longitudinal changes of the users' valuation of the service. This is the research gap that this study is contributing. During a first-/last-mile AB service trial in Stockholm, Sweden, a panel data involving 185 respondents was available for analysis. The first survey was shortly after the launch of the trialled AB service and the second one was four months later. Structural Equation Modelling was used to investigate the changes of users' judging criteria across different socio-demographic groups, due to initial usage and the subsequent usage. The results show that the concerns affecting the users to continue with the service change with an increase in the ride experience. Willingness-to-use of the experienced users was initially affected by their level of appreciation with the safety and travel time with the service. However, ride comfort became a dominant factor with increasing ride experiences.

Abstract [en]

IntroductionThe first wave of COVID-19 pandemic period has drastically changed people's lives all over the world. To cope with the disruption, digital solutions have become more popular. However, the ability to adopt digitalised alternatives is different across socio-economic and socio-demographic groups.ObjectiveThis study investigates how individuals have changed their activity-travel patterns and internet usage during the first wave of the COVID-19 pandemicperiod, and which of these changes may be kept.MethodsAn empirical data collection was deployed through online forms. 781 responses from different countries (Italy, Sweden, India and others) have beencollected, and a series of multivariate analyses was carried out. Two linear regression models are presented, related to the change of travel activities andinternet usage, before and during the pandemic period. Furthermore, a binary regression model is used to examine the likelihood of the respondents to adoptand keep their behaviours beyond the pandemic period.ResultsThe results show that the possibility to change the behaviour matter. External restrictions and personal characteristics are the driving factors of the reductionin ones' daily trips. However, the estimation results do not show a strong correlation between the countries' restriction policy and the respondents' likelihoodto adopt the new and online-based behaviours for any of the activities after the restriction period.ConclusionThe acceptance and long-term adoption of the online alternatives for activities are correlated with the respondents' personality and socio-demographicgroup, highlighting the importance of promoting alternatives as a part of longer-term behavioural and lifestyle changes.

Abstract [en]

The successful adoption of a product or service by its target market or users relies on delivering a product or service in line with their needs and expectations. Failure to do so will likely result in a low rate of uptake or use of the product or service. This study sought to identify the criteria by which potential users of a first-/last-mile automated bus (AB) service would evaluate the service, and accordingly decide whether to use or disregard the service. This research investigated var-ious explanatory factors affecting users' perceptions of the service's quality and utility, and which enhanced or diminished their intentions to use it. The data analysed in this study was collected from a survey conducted in February and March of 2018 in Stockholm, Sweden, during a trial operation of a first-/last-mile AB service. Three-factor theory analysis, commonly used to analyse services, was applied to this data in order to identify users' core perceptions about the service, which in turn influence their intention-to-use the service. Structural equation modelling was used to identify the significant factors that influence the identified perceptions influencing the in-tention-to-use the service. This study found that different subgroups of users prioritised different attributes. Prospective users (with no prior experience with the service) were most concerned with the frequency of service. Their intention-to-use the service greatly increased when the service frequency is comparable to the service frequency of a regular public bus service. Experienced users' intentions to continue using the service greatly increased when the buses were made more comfortable. This study additionally found that users' perceptions of the service's quality were also influenced by numerous factors including the passenger's age, income level, preferred mode of travel for daily trips, preferred mode of travel for first-/last-mile trips, being tech-savvy or not, and their level of familiarity with automated driving technology.

Abstract [en]

A fair distribution of public transport benefits is a commonly stated goal of agencies and operators of public transport. However, it is less complicated and costly to provide accessibility in some parts of cities and their surroundings than in other parts. Densely populated areas, and areas situated closer to the city center therefore often have higher public transport accessibility than remote or sparsely populated areas. Neglecting these realities results with an unrealistic assessment of equity in service provision and hampers their consideration when setting policy goals. In this study, we propose a framework for investigating equity in the distribution of accessibility, where the suggested goal is to provide residents with equal accessibility for equally dense and central areas. For the Stockholm County, we show that accessibility may seem to be distributed horizontally inequitable and vertically regressive. However, once controlling for how dense and close to the city center residents live, while still being horizontally inequitable the distribution of accessibility in Stockholm County is found progressive, i.e., benefiting those with lower incomes. We demonstrate the proposed method for the case of skip-stop train operations and find that it shifts our constructed accessibility measure toward a more horizontally inequitable and vertically progressive state. We conclude that our proposed method can be a potent way for public transport agencies to measure and concretize equity goals and evaluate policy changes.

Abstract [en]

Sweden enacted ambitious environmental goals to mitigate climate change and cut carbon emissions. Swedish public agencies have promoted restricting parking norms to decrease automobile travel. This paper proposes a model to calculate flexible parking norms based on urban form and accessibility factors commonly used in architectural, urban design and planning practices. The transportation systems like the automobile need physical preconditions such as parking spaces and motorways that support driving around. The rationale is that parking norms can be lowered to zero if the urban form supports sustainable mobility choices, namely walking, cycling and public transportation. The model aims to inform municipality officials and developers, architects, urban designers and planners about urban form preconditions and integration with walking, cycling and public transportation as possibilities to reduce parking requirements and meet sustainable mobility goals.

Abstract [en]

The rapid development of automated buses holds great potential for the development of transportation systems. As research into innovative forms of automated transportation systems gains momentum, it is important to understand the public's perceptions of such public transport systems. Previous studies have contributed based on hypothetical scenarios, but not based on real observations. Based on an online survey in Stockholm in March 2019, the current research addresses this gap by investigating the public's perceptions from a real, fully operational, automated public transportation service operated in a mixed traffic environment on public roads. The respondents were selected along the automated bus line in Barkabystaden, Stockholm. Our findings indicate that (1) The presence of onboard operators has a positive impact on respondents' perceived safety, (2) People who have not taken automated buses before have a more negative perception of driving speed of the bus service than people who have taken the buses before, (3) Attitudinal factors, such as public perceptions of safety, driving speed, reliability, and convenience, have a significant influence on the acceptance of the new bus system, (4) As an emerging and innovative transportation mode, automated buses are expected to attract a high share of regular public transportation mode users and the younger generations in the future, (5) Social-demographic characteristics such as gender and income had no significant impacts on the adoption of the new technology. The results provide the characteristics of early bus adopters and their travel behavior and help to prioritize possible investments and allow the policymakers and private industries to identify the special needs of users.

Abstract [en]

Corporate Mobility as a Service (CMaaS) is a type of MaaS that enables mobility within as well as to and from a worksite for employees. The expected benefits of CMaaS are to support a shift towards more sustainable and more effective work-related transport activities. There is a lack of knowledge regarding the impacts of CMaaS and how its performance should be measured. This paper proposes an evaluation framework to measure CMaaS impacts at a system level. The proposed evaluation framework is then applied to evaluate a real CMaaS deployment in Sweden. This paper contributes to knowledge building and guidance to support policy and decision making for CMaaS development and implementation in the future.

Abstract [sv]

Bakgrund: Hur människor reser med kollektivtrafik har historiskt främst analyserats med hjälp av enkäter där svarande har fått ange sitt resande under en slumpmässigt vald resdag. Sådana resvaneundersökningar blir dock mer och mer problematiska att använda då svarsfrekvenserna trendmässigt faller vilket gör att fler enkäter behöver delas ut (vilket ger högre kostnader) samt att den resulterande kunskapen om resvanor blir mindre representativ. En alternativ väg för att förstå resenärers resmönster har öppnat sig i och med inträdet av smarta kort som biljettbärare, med ett sådant kort registreras resor vid biljettvalidering och den informationen kan därefter studeras och analyseras. I region Stockholm har smarta kort (accesskort) använts i kollektivtrafiken sedan 2011 men inte förrän under senare år börjat studerats för att nå förståelse kring resvanemönster. Ett hinder i analysen har varit att korten är så kallade tap-in kort, det vill säga att det endast är vid en resas start som kortet registreras inte vid deras slut. Dessbättre har det internationellt under de senaste åren vuxit fram en välfungerande metodik för att från en serie av inträden i kollektivtrafiken, tillsammans med annan data, sluta sig till var resan slutar samt om det skett några eventuella byten på vägen. Sådan metodik har visats kunna med framgång bestämma uppemot 80-90% av alla registrerade resors rutt och destination.

Metod: I det här projektet som varit ett samarbete mellan Trafikförvaltningen Region Stockholm, KTH och universitetet TU Delft, Nederländerna har resandet med kollektivtrafik i Stockholm analyserats före och efter de taxe-förändringar som genomfördes i januari 2017, då systemets biljettpriser höjdes generellt och zoner togs bort för enkelbiljetter (det var redan tidigare zon-löst för periodbiljetter). Priselasticiteter (hur mycket resandet förändras vid en prisförändring) har beräknats. Vidare har fördelningseffekter av prisförändringarna studerats, dels genom att jämföra priselasticiteter för de som rest för reducerat biljettpris (barn, studerande, pensionärer) med elasticiteter för de som rest för fullt pris. Dels genom att studera hur antalet resor per capita skiljer sig mellan resande från basområden (Stockholmsregionen består av 1300 basområden) med hög och låg medelinkomst, högt och lågt antal bilar per capita, på långt eller kort avstånd från regioncentrum.

Resultat och slutsats: Vi finner att elasticiteter rör sig i ett historiskt vanligt spann för kollektivtrafik kring -0,3 till -0,6 (en elasticitet på -0,1 betyder att resandet minskar med 1% om priset höjs med 10%). Att de som reser på reducerad biljett, bor i områden med låg inkomst eller områden med lågt bilinnehav har lägre priskänslighet än de som reser på fullt pris, bor i höginkomsttagarområden eller har tillgång till bil. De med högre inkomster reser även fler resor än de med lägre inkomster. Vi tolkar det som att de med alternativ möjlighet att resa har lägre priskänslighet än de som är hänvisade till kollektivtrafiken. Det föreliggande projektet har varit en pilot för att visa hur kraftfullt analyser av resandemönster med hjälp av data från smarta kort är och förhoppningen är att dessa metoder kan komma att bli en permanent del i hur kollektivtrafikmyndigheter generellt använder informationen i biljettsystemet för planering och förbättring av kollektivtrafiksystemet.
