Due to the short distances, small cities should have great potential for walking; however, the car still dominates in many places. Moreover, whether and how conditions related to a Northern European location play a role in perceived walkability and subsequent walking behaviour in small cities has rarely been studied. This paper aimed to answer what characterizes walkability in the context of a small city in Norway, using Narvik, Kongsvinger, and Steinkjer as case studies. The investigation is based on a mixed methodological approach, including a survey with public participation geographic information systems (PPGIS), followed by a qualitative investigation with focus group interviews with families. The results suggest that walking for commuting purposes is considered a realistic option by most residents, although the car is used for most trip purposes, indicating that there exists an unfulfilled potential for walking. Results from the walkability assessment with PPGIS suggest that for a positive walking experience, perceived walkability includes a range of walkability indicators of a distinct nature that interact. The interviews provided explanations about important incentives in the cities that encourage the use of cars at the cost of making it attractive to walk. Good access by car stimulates its use despite short distances, and its dominance prevents fulfilling pedestrians' needs regarding calm surroundings and space reserved for vibrant street life and vegetation. Fragmented infrastructure limits parents' confidence in their children's safety. Lighting and maintenance are important in the winter to ensure walkability.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 104014"},"PeriodicalIF":5.7,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A lack of accessibility can result in travel burdens such as high transportation costs or unmet needs and adversely affect well-being. Prior research establishes the inverse relationship between travel burdens and access to transportation options such as public transit and proximity to destinations as well as a person's resources, including their income and access to a personal vehicle. Although travel behavior is understood to differ across rural versus urban contexts, little is known about the nature of travel burdens in rural communities. Using the 2017 National Household Travel Survey, this study quantifies and compares travel burdens in rural versus nonrural communities in the United States. In each context, we quantify and compare i) the magnitude of travel burdens, ii) who experiences travel burdens, and iii) the individual and environmental factors that are associated with travel burdens. We find higher rates of burdensome travel outcomes among rural residents. People who live in rural areas are more likely to report burdensome travel costs and unmet travel needs due to a lack of transportation options compared to people living in nonrural areas, and these differences are exacerbated for people without car access. Dispersed rural contexts are unique in that they exhibit a combination of higher rates of financial burden and unmet need relative to urban contexts. Within rural areas, financial burdens and unmet need are less prevalent for those who live in a small town when compared with those living in more dispersed areas, which suggests that even a small concentration of services and opportunities may facilitate greater access. Collectively, our results highlight the need for research that attends to context-specific needs and strategies to address travel burdens in rural communities.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 104016"},"PeriodicalIF":5.7,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this research gap, this paper empirically investigates the complementary effect of DBSs on public transit using a quasi-natural experiment on the opening of Subway Line 3 in Xiamen, China. Our difference-in-differences estimation results show that the number of DBS trips near newly opened stations increased by 84.7 % on average after the subway opening, representing 40.4 % of all bike-sharing trips within the 100-m buffer zone of the subway station entrance. The results of the spatiotemporal heterogeneity analysis revealed that such complementary effects were concentrated within 2 km of rail transit stations, especially during peak commuting hours and in areas with low bus accessibility and high population density. Moreover, the number of street intersections negatively affected the complementary effect of DBS on the subway when the connection distance was short (i.e., less than 800 m). These findings can inform city governments on the effective use of DBSs to solve the critical last mile problem of public transit and to improve urban mobility, while also illuminating how service providers can optimize capacity allocation and vehicle rebalancing decisions.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 104021"},"PeriodicalIF":5.7,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inequitable distribution of transit supply, which include the transit infrastructure and services, may lead to formation of areas where transit is under provisioned. This work aims to develop an enhanced framework for measuring spatial disparities in accessing transit systems by combining established concepts of Public Transport Accessibility Levels (PTAL) and transit gap. The proposed framework incorporates PTAL as a supply indicator and transit dependent population as the demand indicator while estimating the transit gap. PTAL takes into account the intricate relationship between transit infrastructure and transit services, an aspect that was overlooked by the previous studies on transit gap. Inclusion of PTAL enhances the transit gap evaluation method by offering a deeper understanding and a holistic perspective on the transit system. We demonstrate the proposed approach with an application in Singapore. Additionally, we propose a new classification system based on PTAL and transit gap to distinguish areas where high transit gap is a result of very high demand rather than poor supply. Results show that 44.82 % of the transit dependent population in Singapore lives in high transit gap area out of which 4.69 % population stays in transit desert zones, where supply is poor, and 40.13 % lives in transit stressed zone, where demand is very high. The study also developed a simple decision framework based on PTAL and transit gap scores to suggest effective policy measures for reducing the spatial disparity in transit system accessibility.

This is particularly challenging when concurrent extreme events affect both the ability of households to travel and the functioning of traditional transportation networks that supply resources. This paper examines the use of volunteer-based crowdsourced food delivery as a community resilience tactic to improve food accessibility during overlapping disruptions with lasting effects, such as the COVID-19 pandemic and climate disasters. The study uses large-scale spatio-temporal data (<em>n = 28,512</em>) on crowdsourced food deliveries in Houston, TX, spanning from 2020 through 2022, merged with data on community demographics and significant disruptive events occurring in the two-year timespan. Three research lenses are applied to understand the effectiveness of crowdsourced food delivery programs for food access recovery: 1) geographic analysis illustrates hot spots of demand and impacts of disasters on requests for food assistance within the study area; 2) linear spatio-temporal modeling identifies a distinction between shelter-in-place emergencies and evacuation emergencies regarding demand for food assistance; 3) structural equation modeling identifies socially vulnerable identity clusters that impact requests for food assistance. The findings from the study suggest that volunteer-based crowdsourced food delivery adds to the resilience of food insecure communities, supporting its effectiveness in serving its intended populations. The paper contributes to the literature by illustrating how resilience is a function of time and space, and that similarly, there is value in a dynamic representation of community vulnerability. The results point to a new approach to resource recovery following disaster events by shifting the burden of transportation from resource-seekers and traditional transportation systems to home delivery by a crowdsourced volunteer network.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 104018"},"PeriodicalIF":5.7,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that both commuting duration and living space are significantly associated with the two dimensions of mental health. Furthermore, living space has a quasi-moderating effect on the association between commuting duration and depression, but the moderating effect is insignificant for happiness. This implies that the “trade (commuting) time for (living) space” approach might matter for the absence of mental illness, but this is not an effective approach for the presence of positive subjective well-being.

When proposed infrastructure locations are optimized to provide the highest average access to opportunities using a utilitarian definition of accessibility, marginalized groups and locations may be further left behind. This occurs since the greatest gains to network connectivity, using a utility definition, come from expansions inside or directly adjacent to the densest network areas. We compare utilitarian and equity-driven planning strategies for cycling network expansion and explore tradeoffs in spatial coverage, equity, and efficiency, using Toronto, Canada as a case study. We find that optimizing accessibility in several small regions instead of city-wide leads to an infrastructure plan that is more spatially dispersed. Further, we show that an optimization model targeting low-access areas produces an infrastructure plan with more regions meeting a minimum threshold of accessibility but with lower average accessibility gains, indicating the presence of an equity-efficiency tradeoff. We also find that infrastructure projects that maximize a region's accessibility to jobs are often located outside that region, challenging political perceptions of \"local\" infrastructure and benefits.

This study investigates the evolution of the Latin America and the Caribbean (LAC) container ports and regional sub-systems from 2000 to 2022, analyzing traffic dynamics, shifts in port throughput rankings, and market concentration trends in and among the different coastal regions. Conceptually, this analysis benefits from the notion of evolutionary phases, revealing the stages of a port system's development. Methodologically, 49 LAC ports of international interest are categorized into different coastal regions and tiers based on throughput sizes. Various metrics, including the Gini coefficient, Lorenz curve, Herfindahl-Hirschman Index (HHI), and Kendall Tau (τ), assess port hierarchy and related mobility since 2000. The observed shifts in the hierarchy and market structures, coupled with the fluctuating positions of critical ports, underscore the transition that LAC container ports dynamics experienced in the 21st century. Following a particularly dynamic and volatile evolution observed in the 2000s, the financial crisis of 2008/09 was a critical juncture leading to the transition of the LAC port dynamics from the ‘emerging’ to the ‘maturity’ phase. On the contrary, the pandemic (2019) has not affected the pre-existing hierarchy or the moderate market concentration that was already in progress. The LAC region comprises port sub-systems (coastal ranges) subjected to different tendencies towards (de)concentration, yet mobility in port rankings within each sub-system decreases. The study also reveals the coexistence of this transition with a structural transformation of port governance structures, i.e., granting of concessions of operations to third parties. In 20 of these ports and the above-average mobility of ports are operated by Global Terminal Operators (GTOs), and calls for further research on the (non) causality of these phenomena.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 104011"},"PeriodicalIF":5.7,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
