The spatial planning process is considered an extremely complex system, as it comprises different variables that interrelate and interact with each other. Effectively addressing this spatial complexity necessitates a multidisciplinary approach, as unified methodologies may prove insufficient. Specifically, in urban planning, it is increasingly crucial to prioritize bike lanes, bike stations, and pedestrian zones, for functional transportation infrastructures. This approach can enhance cities by improving air quality, reducing emissions, and boosting public health and safety through physical activity and accident prevention. However, implementing these changes requires careful planning, community engagement, and stakeholder collaboration. This paper proposes a hybrid model for identifying optimal locations for bike lanes, bike stations, and pedestrian zones adopting Real-Time Spatial Delphi and Generative Adversarial Networks (GANs). The Real-Time Spatial Delphi is a modified version of the traditional Delphi method that incorporates real-time feedback and visualization of group response in real-time, aiming to achieve a convergence of opinions among experts on the territory. Nevertheless, these judgments are a spatial representation not visible in reality, and with the spread of artificial intelligence models, different implementations can support the planning process, such as the use of GANs. In this case, GANs can be exploited by adopting pre-existing location images resulting from experts' judgments to illustrate the proposed intervention's visual impact. To demonstrate the effectiveness of our hybrid model, we apply it to the city of Dublin. The results showcased how the method helps stakeholders, policymakers, and citizens in visualizing the proposed changes and gauging their potential impact with greater precision.

Abstract There is currently a lack of studies exploring how transport investments and school admission policies in a city can affect the distribution of accessibility to schools. The aim of this study is to investigate if, for whom, and the ways in which, accessibility to schools can change following (1) a change to the city’s public school admission policy and (2) investments in public transport infrastructure and adjustments to the public transport system. We draw on the case of Malmö, Sweden to examine the potential effects of these changes. This study is focused specifically on those in grades 7–9 (aged approximately 13–15), a group whose independent mobility is starting to take form. A geospatial analysis was carried out in order to compare the change in demographic makeup between school catchment areas (real and hypothetical) before and after the changes were made. The geospatial analysis utilises a cumulative opportunity accessibility model that takes into account typical public transport travel times both before and after these new measures were implemented. Findings indicate that the (hypothetical) school catchment areas have been redistributed to a considerable extent following both interventions, but particularly following the change to the public school admission policy. These redistributions have in turn resulted in changes in the socio-economic characteristics of the hypothetical school catchment areas. While the redistribution of school catchment areas could potentially change the socio-economic composition of schools in Malmö, the effects are not equally distributed throughout the city. While the addition of the new train line was the main focus of this study, it was found that other changes in the public transport system between 2018 and 2019 also played a role in determining which schools students could and could not access. The findings from this study highlight the importance of carefully considering the interaction of different effects when assessing policy alternatives.

Abstract The positive effects that Mobility-as-a-Service (MaaS) is envisioned to have on transport can only be reaped if people are using MaaS. Yet, the understanding of the user perspective on MaaS is incomplete and primarily based on experiments with non-users. To address this shortcoming, this paper reports user experiences from a trial of a high-level MaaS service in Sydney, Australia. Based on questionnaires and interviews, it analyses who participated in the trial and why, and whether the trial experience satisfied their motives. The contribution to the literature on MaaS is three-fold. Firstly, most of the people that participated in the trial were frequent users of both public transport and private cars. This supports the notion that multi-modal travellers are likely early adopters of MaaS and contradicts the fear that MaaS does not appeal to private car users. Secondly, a desire to contribute to innovation and curiosity about MaaS were the main motives for signing up for the trial, which highlights the important role an inviting setting for experimentation, such as a trial, can play in stimulating MaaS adoption. Thirdly, many participants struggled with making the trialled service work for them and on average they seemed to value the support and feedback functions higher than other service features. This underscores the novelty of MaaS, compared to existing service models, and reiterates the notion that more than an app and a few subscription plans is needed to make MaaS useful for users.

Abstract Background Last-mile delivery by drone is expected to be a promising innovation for future urban logistics. However, in addition to adoption of services by customers, leveraging this delivery method will depend essentially on a positive public perception of such services in urban airspace. Objective This article provides novel and comprehensive insights into factors driving or impeding citizens' attitudes towards drone delivery. Methodology The article develops a structural equation model that derives from a sequential exploratory mixed methods design. In the first step, factors affecting attitudes towards drone delivery were identified within the scope of five focus groups and converted into the development of a questionnaire. In the second step, a German population-representative survey was conducted through telephone interviews, which provided reliable data to test the model (n = 819). Results Expected risks (particularly stress due to traffic in lower airspace, noise, and visual disturbances), as well as expected benefits (particularly fast and time-flexible delivery), significantly affect attitudes towards drone-based delivery, while the individual level of technological openness (technophilia) does not have a significant association. Moreover, the model reveals that the expected risks of drone deliveries are stronger associated with public attitude than with expected benefits. Conclusions The provided framework suggests fashioning policies and drone delivery applications that focus on mitigating social, spatial, and visual risks while achieving maximum utility for customers.

Abstract Demerit points systems (DPS) have been used in many countries as a means for improving road safety, by monitoring traffic law violations of drivers and applying corrective measures to repeat offenders, while knowledge on their safety impacts is yet incomplete. This study examined the DPS impacts on committing traffic offenses and accident involvement of drivers, in Israel, based on files of the national Licensing Authority and complementary accident files. Models were developed to evaluate changes in violation and accident rates of drivers, who underwent the DPS corrective measures, in after the treatment related to the before period, and accounting for changes observed in the matched comparison-groups. The findings showed that during the three-year period after the measures' implementation, the decrease in committing violations was of 70%, and simultaneously, there was a decrease in drivers' accident involvement, on average, of 1% in severe accidents and of 11% in total injury accidents. The effects were consistent across various groups of drivers by the corrective measures applied and the type of license. The study results support the continued use of the DPS, to improve drivers' behaviors and road safety. To increase its impacts at the national level, the DPS implementation should be supported by stable police enforcement and publicity efforts.

Abstract Mobility-as-a-Service (MaaS) system is regarded as one of the emerging solutions to offer integrated, seamless, and flexible multi-modal mobility services as an alternative to privately owned mobility resources. MaaS is expected to change the way users will choose their modes of transport to reach their daily activities, and how service providers will generate profits, cooperate, and compete. To successfully deploy MaaS to reach the intended goals, it is critical to develop feasible and sustainable models that capture the diverse needs of customers as well as the diverse and often competing objectives of service providers. This paper aims to provide a general modelling framework and a critical and descriptive analysis of the relevant literature relating all main actors in the MaaS ecosystem, and identify and discuss all factors that are considered relevant, focusing on the actor’s decision-making processes and their correlations. This review shows the large variety and interaction of factors influencing MaaS adoption and their impact on forecasting MaaS appeal. It is also observed that current travel behaviour and multi-modal transport models are not fully capturing the diverse travel needs and choices of potential MaaS users. Recent advancements in agent-based simulation and discrete choice modelling offer potential solutions to address this gap, and future research should aim in that direction. Finally, the review analyses the interaction between MaaS actors, including customers, service providers, the government, and the MaaS Broker, highlighting the complexity of the modelling process comprising all actors of the MaaS ecosystem. Therefore, it is recommended to prioritise future research in exploring these areas.

Abstract The smart city concept is being viewed as part of the urban future, integrating technological advances, multi-sectorial collaboration, and innovative open markets with strategic goals and ambitions to achieve sustainable urban development. Smart mobility is considered a vital element of the smart city, given that urban transport systems should become more efficient and sustainable. With this in mind, we raise the question: how sustainable is smart mobility? To answer this, we review smart city strategies and measures of fourteen mid-sized cities of the Nordic Smart Cities Network, identifying smart mobility goals together with proposed or implemented mobility measures. We evaluate how they align with sustainable mobility and how effective they are with the help of two analytical frameworks: a) the EU’s Sustainable Urban Mobility Planning (SUMP) objectives and b) the S.M.A.R.T. objectives. In doing so, we assess to which degree smart mobility strategies and measures in Nordic smart cities contribute to sustainable urban mobility and development, and how they contribute to achieving sustainable and smart city goals in terms of feasibility and accountability. The study reveals that measures mainly address the SUMP objectives relating to efficiency and environment, with little focus on inclusive and safe mobility planning that caters to attractive cities and high quality of urban life. Another finding is that smart mobility measures are relatively conventional, and their goals and ambitions are often stated on an abstract level and rarely measurable with specific indicators. Thus, there seems to be a lack of feasibility and accountability related to smart mobility measures, as well as a lack of focus on social sustainability.

Abstract Background Preventing fatal traffic accidents towards Vision Zero is a challenge for the society. The collection of critical events from video recorded traffic data is of essential value for a better understanding on how and under what circumstances critical situations evolve. Identified behavioral patterns and derived infrastructural measures cannot only help to make driving safer, but also help to mature automated driving functions (ADFs) to make automated vehicles drive and interact more like humans especially in challenging situations. One flaw when developing ADFs is the dependency on synthetic simulated traffic scenarios. Method In this paper, a novel probability-based framework is proposed allowing to measure the degree of criticality C(d) based on two dimensions explaining risk: severity ( delta-v ) and proximity (distance). Results This metric is applied on real data of a roundabout. An initial evaluation of it was conducted using both a novel proposed method that takes the reaction of the second vehicle merged into account, and a practical application that shows a potential correlation between the traffic expert's perceived risk and the metric. Conclusion Quantifying risk on each of the collected real traffic scenarios makes testing ADFs possible in further more reliable and significant scenarios like near-crashes.

Abstract Background Since air pollution and physical inactivity pose major public health risks, switching from cars to alternatives like public transport, cycling, and walking is important. Therefore, it is beneficial to identify key events for changes of mode choice. Methods We examined the association between risk perception and mode choice during the temporary closure of a road bridge between two major German cities in early 2020 using binary and multinomial regression models. Results 679 people participated in the survey. We found that 22% of car users switched to alternatives. The higher the perceived health risk from traffic-related air pollution, the more likely car users switched to alternatives (odds ratio [OR] = 1.76, 95% CI [1.14, 2.71]). Discussion Attitude, subjective norm and perceived behavioral control were associated with maintaining but not with switching transport modes. In conclusion, the closure of a main road bridge may present a key event. To explain mode choice, risk perception is a potential extension to the theory of planned behavior.

Results 679 people participated in the survey. We found that 22% of car users switched to alternatives. The higher the perceived health risk from traffic-related air pollution, the more likely car users switched to alternatives (odds ratio [OR] = 1.76, 95% CI [1.14, 2.71]).

Abstract Background Many regions worldwide are struggling to create a mode shift from private cars to more sustainable transport modes. While there are many reviews regarding travellers’ preferences and travel mode choices, there is a lack of an updated review that provides a comprehensive overview of the factors that make public transport systems attractive. Aim This review aims to fill the knowledge gap by offering insights into the factors influencing travel behaviour and the demand for public transport. It has two primary objectives: • Summarize general conclusions drawn from international literature reviews. • Present specific insights on the topic pertaining to the Nordic countries. To the best of our knowledge, this is the first review with a Nordic focus regarding public transport preferences and travel mode choices. The special focus on these countries is motivated by their relatively more ambitious policies for reducing emissions in the transport sector compared to many other countries, and their relatively high usage of public transport today. Methods To achieve these objectives, we conducted a review of existing literature. This review encompassed international literature reviews and included an examination of results from the Nordic countries. Findings The findings show that reliability and frequency are important factors for creating an attractive public transport supply. However, there is only limited evidence regarding the impact of improvements in these attributes on public transport demand, so this needs more research. This review highlights the importance of understanding the underlying motivations for travel mode choice and provides recommendations on areas for further investigation to understand the attractiveness of public transport supply.
