Transportation Research Interdisciplinary Perspectives

Leaders around the world have embraced the idea of a "15-minute city". This urban planning concept proposes a city where residents can meet their essential needs within a short walking or cycling trip from their home. Local access to grocery stores is a necessary component for cities to achieve the 15-minute city. This study aims to evaluate local accessibility to grocery stores by walking and cycling in the City of Vancouver. We used a cu-mulative opportunity measure to count the number of grocery stores available within a 15-minute walk and cycle from people's homes. To evaluate accessibility from the perspective of younger and older travellers, we considered different travel speeds. Our results show there is good accessibility to grocery stores when cycling, with less than 1% of the city's population not having a grocery store within a 15-minute cycle. When assuming a walking speed of an older pedestrian, around one-fifth of the population did not have access to a grocery store in their local area. The neighbourhoods that did not have a store within a 15-minute walk had higher proportions of children, older adults, and visible minorities, and lower rates of employment and post-secondary education attainment. In seeking to improve accessibility via walking and cycling, cities should prioritize grocery store locations and investments in pedestrian and cycling infrastructure to underserved neighbourhoods and populations.

Is the 15-minute city within reach? Evaluating walking and cycling accessibility to grocery stores in Vancouver

In urban planning and design, a holistic perspective is needed to examine multiple potential scenarios in future developing plans. Access (or accessibility) is a concept that measures the performance of a city in terms of how easily residents can reach their desired activities. The land use pattern and the transport network configuration are the two critical elements of spatial access measures. This study investigates whether access-oriented design can improve accessibility outcomes, and disentangles access benefits from network design and land use patterns. A generic superblock with two types of street network design is defined, and populated with two different land use allocation strategies. Local access is measured from transit stops. Furthermore, to test the hypothesis at a larger scale, the Liverpool LGA in Sydney is selected, and different combinations of land use pattern and network topology are tested. Results indicate that the land use pattern plays a vital role in the local access; however, the network configuration significantly impacts the access at the regional scale. The application of access-oriented designs in future urban growth is discussed.

Access-oriented design? Disentangling the effect of land use and transport network on accessibility

Self-driving vehicles are a tool that contributes significantly to sustainable development, both nationally and globally, as their positive effects extend beyond national borders. For their wider use, we need an appropriate regulatory framework as well as certain technical capabilities. It is not only technically sophisticated vehicles that are important, but also the infrastructure that supports automated driving. This paper analyses the legal frameworks of selected states, aside from those frameworks at international and EU level. The research indicates that national regulations often concentrate on the testing phase of automated vehicles. Furthermore, these rules frequently require a certain degree of driver involvement, highlighting that some form of human control remains essential. It seems that regulation does not match the speed of technological development or is sometimes somehow unsynchronized with it.

The COVID-19 outbreak meant that using public transport was potentially unsafe for risk of catching and transmitting the virus. UK anxiety is high with lockdowns preventing a normal way of life for over a year. A lack of ability to travel freely causes numerous declines in quality of life including social isolation and poor physical and mental health. People need crowding information to choose safer travel options and subdue coronavirus. To provide effective guidance, it is essential to empirically formulate messaging to create clarity and trust which can be acted upon in confidence. Behaviour Change Techniques incorporating the Behaviour Change Wheel and COM-B model have been utilised in vast areas of public health intervention development and messaging. There is consensus that public transport information needs to be clearer and more accessible but BCTs have not been utilised in the development of public transport advice. This paper outlines the development of crowding messaging for public transport on a platform available to UK travellers. Barriers and facilitators were explored; related behaviours, intervention functions and behaviour change techniques were mapped. Specific message phrasing was developed utilising the mapped functions and advice from the literature. With the COVID-19 outbreak, having accessible and effective messaging for safely using public transport is a continuation of the work recently conducted examining the best ways to present public health information. It is important to be transparent when developing messaging and interventions accessible to the public and this work forms a basis for continued exploration and development in this area.

Following a rapid urban development and mass motorisation, Chinese city planning has started to refocus its attention towards active transportation. It is therefore an opportune time to address the under-investigated issue of young children's transportation. Indeed, in the Shanghai city centre, more than a third of the pre-school students are walking to school while almost half of them are transported on two-wheeled vehicles, highlighting the necessity for appropriate urban design solutions. In a previous study Chevalier and al. initiated this work and examined the barriers to cycling on the way to kindergartens. Based on their conclusions, minor adjustments to existing infrastructure could help to meet the population's expectations in terms of safety and comfort. Using a survey questionnaire on safety perception and drawings of the detailed route to school, together with its corresponding points of danger, over 400 responses were collected at kindergartens in inner Shanghai. Data analysis underscores the increase in perceived danger at crossroads, hinting us to the need for a refined study of the trajectories at major intersections. As a proof of concept we isolate a crossroad, thoroughly evaluate its surroundings, and suggest simple design solutions, which could result in drastic improvements for soft mobility. In particular we show that improving connectivity could foster solutions significantly lessening the perceived danger. We believe this approach represents a valuable asset to the development of active transportation, as it can be applied at little cost, allowing city planners to improve the existing infrastructure and vulnerable road users to feel safer.
