This paper presents a mixed-method analysis of car ownership in Reykjavik, Iceland, a location with a high motorization level and deeply rooted car culture. We utilize qualitative interviews to understand vehicle possession reasons and elaborate the study with statistical analysis using a softGIS survey dataset with characteristics of the respondents and their residential location. We focus on adults aged 25 to 40, who are suggested to be less car-oriented than older generations. We also describe the historic development of Reykjavik’s car culture to give a perspective for the findings. We show that even among the studied age group, car ownership is still seen as a social norm, with few even seeing it possible to live without a car, and the public transport system is seen as giving a poverty stigma. However, we still find an increasing share of car-free households towards the city center. Still, the built environment impact is limited to the city center, which has a higher proportion of small adult-only households residing in shared apartments than other areas. Moreover, there seems to be a three-fold connection between having a child, acquiring a car (if not already possessed), and choosing a suburban residential location. Some indications of residential self-selection related to car ownership were found, but pro-car attitudes and residential location independently influenced car ownership. This study helps to understand the reasons for high car dominance and supports designing policies to reduce car-dependency, not just in Reykjavik but also elsewhere.

Travel Distances

This article presents findings from a mixed-methods study on residential location and travel in the Reykjavik capital region, Iceland, drawing on a combination of a tailor-made questionnaire survey and in-depth qualitative interviews, including cross-sectional and before–after analyses. A residential location close to the main city center of Reykjavik contributes to shorter travel distances and lower shares of car travel. The effect of proximity to the city center is particularly strong for commuting but exists for non-work travel and overall car-driving distances too. There are also effects of proximity to a main second-order center and local centers and of local-area population density, but these effects apply to fewer aspects of travel. The rationales for location of activities and travel mode choice identified in the qualitative interviews explain why travel distances and modes tend to depend more on proximity to the main city center than on neighborhood-scale built environment characteristics. The main patterns found in the Reykjavik area are in line with findings in several earlier studies in the Nordic countries and elsewhere. However, through its methodological approach, the investigation adds to the few studies on the topic where results are underpinned by combined qualitative and quantitative methods and inclusion of before–after analyses.

Abstract. This paper is an empirical mixed-method study on car use in an urban context. It explores the questions: What mobility practices do people in the city display? What role does car use play in this context? What is the guiding, underlying logic behind personal car use? The findings help to understand mobility practices and their underlying logic. The central component is a user typology based on a quantitative survey and qualitative interviews. The study aims to present an empirical description of mobility practices and the guiding logic of different mobility types in Berlin. The findings offer starting points for user-specific measures to encourage people to use new mobility concepts instead of their personal car.

City centers worldwide are perceived as essential parts of the city, where city memories are preserved and its identity is expressed. They are planned to satisfy the functional requirements and pleasurable qualities of the city. Under the accelerating urbanization of the modern city, several challenges face these centers including demographic, economic, and environmental challenges. This requires a continuous and incremental urban development process based on clear strategy and action plans. Thus, this study focuses on urban development strategies of city centers, with a focus on Rafah city located in the Gaza Strip, Palestinian Territories. The geographic location of this city near the Palestinian-Egyptian borders makes it a promising commercial city at local and regional levels. Thus, the current situation of Rafah city center has been analyzed, and several development strategies have been proposed. This has been done through a field survey based on observation and a questionnaire directed to city center users. It has been found that there is a great potential of Rafah city center to be developed as a commercial center. In this regard, several strategies and required actions have been proposed in the fields of transportation, environmental quality, shopping activities, investment opportunities, and visual perception.

There is increasing evidence that ridehailing and other private-for-hire (PfH) services such as taxis and limousines are diverting trips from transit services. One question that arises is where and when PfH services are filling gaps in transit services and where they are competing with transit services that are publicly subsidized. Using weekday trip-level information for trips originating in or destined for the city center of Portland, OR from PfH transportation services (taxis, transportation network companies, limousines) and transit trip data collected from OpenTripPlanner, this study investigated the temporal and spatial differences in travel durations between actual PfH trips and comparable transit trips (the same origin–destination and time of day). This paper contributes to this question and to a growing body of research about the use of ridehailing and other on-demand services. Specifically, it provides a spatial and temporal analysis of the demand for PfH transportation using an actual census of trips for a given 2 week period. The comparison of trip durations of actual PfH trips to hypothetical transit trips for the same origin–destination pairs into or out of the central city gives insights for policy making around pricing and other regulatory frameworks that could be implemented in time and space.

AbstractIn urban renewal processes, metro line systems are widely used to accommodate the massive traffic needs and stimulate the redevelopment of the local area. The route choice of pedestrians, emanating from or going to the metro stations, is influenced by the street-scale built environment. Many renewal processes involve the improvement of the street-level built environment and thus influence pedestrian flows. To assess the effects of urban design on pedestrian flows, this article presents the results of a simulation model of pedestrian route choice behavior around Yingkoudao metro station in the city center of Tianjin, China. Simulated pedestrian flows based on 4 scenarios of changes in street-scale built environment characteristics are compared. Results indicate that the main streets are disproportionally more affected than smaller streets. The promotion of an intensified land use mix does not lead to a high increase in the number of pedestrians who choose the involved route when traveling from/to the metro station, assuming fixed destination choice.

Urban distribution in medium-sized cities faces a major challenge, mainly when deliveries are difficult in the city center due to: an increase of e-commerce, weak public transportation system, and the promotion of urban sustainability plans. As a result, private cars, public transportation, and freight transportation compete for the same space. This paper analyses the current state for freight logistics in the city center of Pamplona (Spain) and proposes alternative transportation routes and transportation modes in the last-mile city center distribution according to different criteria evaluated by residents. An analytic hierarchy process (AHP) was developed. A number of alternatives have been assessed considering routes and transportation modes: the shortest route criterion and avoiding some city center area policies are combined with traditional van-based, bike, and aerial (drone) distribution protocols for delivering parcels and bar/restaurant supplies. These alternatives have been evaluated within a multicriteria framework in which economic, environmental, and social objectives are considered at the same time. The point in this multicriteria framework is that the criteria/alternative AHP weights and priorities have been set according to a survey deployed in the city of Pamplona (Navarre, Spain). The survey and AHP results show the preference for the use of drone or bike distribution in city center in order to reduce social and environmental issues.

Carbon Transport

Shared mobility options, such as car sharing, are often claimed to be more sustainable, although evidence at an individual or city level may contradict these claims. This study aims to improve understanding of the effects of car sharing on transport-related emissions at an individual and city level. This is done by quantifying the greenhouse gas (GHG) emissions of the travel habits of individuals before and after engaging with car sharing. The analysis uses a well-to-wheel (WTW) approach, including both business-to-consumer (B2C) and peer-to-peer (P2P) car-sharing fleets. Changes in GHG emissions after engaging in car sharing vary among individuals. Transport-related GHG emissions caused by car-free individuals tend to increase after they engage in car sharing, while emissions caused by previous car owners tend to fall. At the city level, GHG emissions savings can be achieved by using more efficient cars in sharing systems and by implementing greener mobility policies. Changes in travel habits might help to reduce GHG emissions, providing individuals migrate to low-carbon transport modes. The findings can be used to support the development and implementation of transport policies that deter car ownership and support shared mobility solutions that are integrated in city transport systems.

The 20,000-student Boise State University campus is located about 3 km from the center of the city of Boise. There is a significant amount of travel between the campus and the city center as students and staff travel to the city to visit restaurants, shops, and entertainment centers. Currently, people make this trip by car, shuttle bus, bike, or walking modes. Cars and shuttle buses, which share the same road network, constitute about 76% of the total trips. As road congestion is expected to grow in the future, it is prudent to look for other modes that can fulfill the travel demand. One potential mode is an aerial tramway. However, an aerial tramway is not a common mode of urban travel in the US. This research describes how the stated preference method was used to estimate demand for a mode that does not currently exist. An online stated preference survey was sent out to 8681 students, faculty, and staff and 1821 valid responses were received. Only about 35% of the respondents expressed their willingness to choose an aerial tramway for various combinations of cost and convenience of the new mode. Respondents were also found to favor convenience over cost for the new mode.
