Increasing accessibility and balancing its distribution across space and social groups are two fundamental goals to make transport more sustainable and equitable. In the next decades, autonomous vehicles (AVs) could significantly transform the transport system, influencing accessibility and transport equity. In particular, depending on the assumed features of AVs (e.g., private or collective) and the considered spatial, social, and regulative context (e.g., rural or urban areas), impacts may be very different. Nevertheless, research in this field is still limited, and the relationship between AV assumptions and accessibility impacts is still partially unclear. This paper aims to provide a framework of the key and emerging aspects related to the implications of AVs for accessibility and transport equity. To set this framework, we perform an analysis of the scientific literature based on a conceptual model describing the implications of AVs for the distribution of accessibility across space and social groups. We recognize four main expected impacts of AVs on accessibility: (1) accessibility polarization, (2) accessibility sprawl, (3) exacerbation of social accessibility inequities, and (4) alleviation of social accessibility inequities. These impacts are described and analyzed in relation to the main AV assumptions expected to trigger them through different mechanisms. Based on the results, some recommendations for future studies intending to focus on the relation between AVs, accessibility, and transport equity are provided.

The last-mile in the courier express parcel (CEP) sector is the most challenging part of the overall transport chain. This is, among other reasons, because many recipients are not at home when deliveries take place. On the other hand, it is for many recipients inconvenient that they have to collect their parcels at different pickup shops varying from logistics service provider (LSP) to LSP. One solution is to employ (open) parcel lockers which are conveniently located for recipients and which allow successful (first) deliveries for LSPs. In this paper, we investigate the impact of parcel lockers with respect to traveled distances as well as CO2 emissions. We show that under certain situations, parcel lockers positively contribute to both aforementioned performance indexes. Based on our observations, we formulate recommendations how to support the implementation of parcel lockers.

Engineers and planners are always jointly responsible for the usability of their interventions. In the transport sector, universal design is a planning imperative to ensure that all user groups participate equally in traffic. Usually, only physical impairments are in the foreground. However, there is an ever-increasing group of people with psychological impairments. Mental health diseases, especially phobias, anxiety, and compulsory disorders, are one of the most prevalent diseases in industrial countries – one-year prevalence rates are estimated at 10 up to 15%. Although rules, regulations, policies and action plans have been established to create an overall inclusive transportation system, the needs of people with mental impairments are mostly not considered. At the same time, participation in traffic is important for people with mental impairments to satisfy their daily needs and to reach therapeutic institutions. In addition, social interaction and the mastery of every-day tasks strengthens self-confidence and supports the healing process. Not least for that reason, the UN SDGs have been formulated. By conducting an exploratory study, the behaviour and needs of people with phobias, anxiety and compulsory disorders and the effects on their participation in traffic were explored. The paper shows general aspects concerning the traffic behaviour of people affected in the course of the disease. Furthermore, different forms of mobility barriers for people with phobias, anxiety and compulsory disorders were identified, distinguishing between infrastructural barriers, social barriers and organisational barriers. As a result, several approaches to support the participation in traffic of people with phobias, anxiety and compulsory disorders, based on coping strategies used by the target group, are mentioned. In addition, the paper identifies potential future challenges in context with mobility trends, concerning the accessibility of the transportation system for affected people, as well as further research needs.

In terms of freight transportation it is essential to pick the most convenient mode(s) of transport (MOT). To get a more flexible system, one can assume that the number of transport options at each hub should be maximized. Therefore, it is investigated how a new hub concept comprising four MOT, a so-called “quattromodal freight hub”, can be implemented in the existing transport system from a traffic planning, technological and organizational point of view. The research incorporates screening existing literature and best practices, conducting stakeholder interviews as well as performing site visits at the best practice areas Hamburg (Germany) and Constanta (Romania). Furthermore, the implementation perspective for a quattromodal freight hub in the city of Vienna (Austria) is examined. The research revealed the strengths, weaknesses, opportunities and threats of the concept from a theoretical and practical perspective. Four options to create a quattromodal freight hub in the city of Vienna could be identified taking the effects on the overall transport system capacity, arising costs and the legal framework into account. Cost and efficiency related decision criteria are decisive for the implementation of a quattromodal freight hub. An implementation in the city of Vienna is attractive in terms of prestige and unique selling proposition for the region but at the same time requires further research in terms of legal aspects and impacts on the region.

Based on a case study at the Port of Vienna a standardized simulation system with new algorithms is developed that combines and optimizes significant (administrative, operational and logistic) processes as well as location based conditions. The medium- to long-term strategy concept for an efficient supply chain at multimodal hubs takes into account all detailed considerations and implementation requirements. With the help of layout planning and logistical process optimization, waiting times are to be reduced and the internal hub supply chain will be optimized with regard to the use of resources (energy, space, time). On the basis of standardized procedures and the presentation of an ideal target process chain, the development of an optimized solution for multimodal hubs is implemented, which not only integrates business-related components but also overall economic aspects.

The demographic change in view of the aging population leads to people suffering from dementia worldwide. In order to maintain the social participation of this group of persons and thus their mobility for as long as possible, it is important to deal with social aspects of dementia. In this context, the preservation of independent mobility of people with dementia is also important. The purpose of this paper is to present findings of a qualitative study, in which barriers for traffic participation have been identified from the perspectives of experts, caregivers, and patients. In order for dementia patients to have a sense of security and orientation, spaces should be constructed so that certain patterns can be aligned with dementia patient's cognitive capabilities. The paper distinguishes different forms of barriers, such as cognitive (e.g. information overload, spatial-visual impairment, situational complexity), social (e.g. stigmatization, cognitively or emotionally induced conflicts) and physical barriers which are specific for dementia.

The integration of innovative means of transport, like the Hyperloop concept, cargo drones and cargo zeppelins, into existing transport networks presents a challenge not only from a technological point of view, but also has various economic, social, and ecological impacts. Therefore, this work estimates regional impacts of a connection utilizing innovative means of transport. The presented scalable method is not limited to a specific type or number of regions, but capable to estimate the impacts of large-scale transport networks covering a great number of diverse regions. The work contributes to quantitative transport network modelling, as it provides a method for the quantification of essential regional impacts, which can be incorporated into comprehensive transport network models. The applicability of the method is demonstrated with a real-life example. As a result, values of an impact indicator for selected international regions are available for a set of innovative means of transport.

Population growth in cities and expanding city territory as well as population decline in rural areas pose a challenge for the existing transport network. Consequently, we observe a rapid change in transport infrastructure and transportation technology within the last few years. Due to novelty or differentness, it will initially be challenging to integrate them into the existing network in Western European cities and to identify suitable corridors leading to especially beneficial effects on the overall transport network. The effects of new technologies and (high-performance) infrastructures are hardly examined. It remains unclear how these novel transportation technologies will change society, our understanding of spatial proximity, mobility, and consequently the logistics sector. In this work, we give an overview regarding first considerations and reflections on the impacts of the changes and developments in the field of freight transportation. Our work mainly focusses on the estimation of the impacts of high-performance transport technologies on the society, spatial proximity, and the logistics sector while extending the European transportation network accordingly. In our understanding, we refer to high-performance transportation technologies as mobility systems with either high throughput (fast and/or high utilization loads) or very flexible application. To be more specific, we focus on Hyperloop technologies, Cargo-Sous-Terrain, freight airships, and drones.

Providing an inclusive transport system is a global ambition. Whereas, mobility needs and mobility barriers of people suffering from a physical impairment have already been observed frequently, people suffering from mental impairments (due to e.g. anxiety disorders, obsessive-compulsive disorders, dementia or other degenerative diseases) are often overlooked. Numerous studies already suggest that the number of people with mental impairment will significantly increase due to the demographic change and is also shown by the prevalence of mental diseases. Whereby, not even the data collected do necessarily give the full picture of the actual situation. Thus, the importance of mobility needs and mobility problems of people with mental impairments will gain dramatically. Participating in the transport system is a basic need that furthermore requires the ability of adopting different roles (e.g. driver, pedestrian). Due to explanatory studies of the authors, it could be shown what kind of problems people with mental impairment are faced with while participating in the transport system or interacting in public space. Thus, these studies represent the first step that is needed to consider the specific needs of people with mental impairments in future planning. The identified problems of people who are suffering from mental impairment are various. Thereby it can be distinguished between problems triggered by structural (e.g. absence of emergency buttons, spacious stations), organisational (e.g. absence of security stuff, lacking information according time table of transit) or social conditions (e.g. crowed places or vehicles, stigmatisation). This paper presents an overall view of specific requirements of people with mental impairment and suggests possible solutions for planning and designing an inclusive transport system.

Travel time reliability represents an essential component in individual decision making processes for transport participants, particularly regarding mode choices. As criteria that describe the quality of both transportation systems and transportation modes, travel time reliability is already frequently compiled, analysed and quoted as an argument. Currently, travel time reliability is solely mentioned on monomodal trips, while it has remained unconsidered on multimodal transport participation. Given the fact that multimodality gained significantly in importance, it is crucial to discuss how travel time reliability could be determined on multimodal trips. This paper points out the challenges that occur for applying travel time reliability on multimodal transport participation. Therefore, examples will be given within this paper. In order to illustrate theoretical ideas, trips and influencing factors that could be expected within the everyday transport behaviour of commuters in a (sub)urban area will be described.

Examining the spatial distribution of bicycle accidents under different conditions and in different periods is an important issue for increasing cyclist safety. A point pattern analysis methodology of 1,437 bicycle accidents that resulted in injury or death in the city center of Vienna, Austria, between 2012 and 2014 is described. Network-based kernel density estimation was used to examine the hot spots of bicycle accidents, and the network-based nearest-neighbor distance was taken into account to check the significance of the hot spots. Moreover, the global cross nearest-neighbor distance was used to test the effect of urban components on the distribution of bicycle accidents. An understanding of the temporal and conditional differences was obtained by analyzing the accident data in terms of four classifications: all accident data and then the accident data classified according to season, light conditions, and precipitation conditions. It was concluded that the bicycle accident hot spots varied in space according to season, light, and precipitation conditions. Also, these detected hot spots were significant for the pattern of accidents, no matter what classification was used. Besides these points, at the .95 confidence level, bicycle accidents tended to cluster by signalized intersections, bus and tram stations, subway stations, and city bike stations. As a result, a systematic framework was proposed for spatiotemporal analysis of bicycle accidents for the built environment. The framework can serve as a guide to determine effective strategies for cyclist safety in urban areas.
