Mobility hubs are physical locations where people change modes of transport and, therefore, bring forth multi-actor and multi-level governance arrangements. Mobility hubs are also a means to tackle the (re-)distribution of urban space and prioritization of environmentally friendly modes of transport. Nevertheless, research on sustainable mobility has identified an implementation gap in the sector. To date, academic literature on mobility hubs and multimodality has predominantly focused on design and user needs, integration into urban space, and environmental impact. In contrast, this article asks how the governance framework affects the implementation of mobility hub networks. The theoretical approach combines an analysis of governance arrangements with literature on smart mobility governance. This multifaceted analytical framework facilitates the examination of various dimensions and dynamics of the governance arrangements behind mobility hubs. Based on a qualitative content analysis of local policy documents and 12 semi-structured expert interviews with local and regional stakeholders, this study analyzes two case studies, in Munich and Vienna. The analysis reveals fragmented multi-level and multi-actor governance arrangements that require complex coordination processes and experimental governance. Parking management and shared mobility regulation are powerful municipal instruments for shaping mobility policies and installing mobility hubs. However, the dominant normative ideas of automobility and neoliberal logic of scarcity and behavioral change are hindering the pursuit of more ambitious changes in urban infrastructure. Mobility hubs can only fulfill their potential to add and connect mobility services if they simultaneously tackle the predominance of automobility.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"163 ","pages":"Pages 323-334"},"PeriodicalIF":6.3,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143173810","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}

Therefore, policies that improve pedestrians' perception of the built environment are crucial for policymakers and researchers alike. This paper investigates the influence of built environment factors on perceptions of <em>safety and comfort,</em> as well as pedestrians' preferences for sidewalk characteristics in two Colombian cities: Barranquilla and Santa Marta. For this purpose, we designed a novel survey that combines a choice experiment using real images of residential and commercial areas with a set of perception indicators to estimate hybrid choice models. The study's findings have significant practical implications for urban planning and policy development. In the commercial sector, sidewalk width is the most relevant attribute, followed by obstacles and, to a lesser extent, the presence of pedestrians. In residential sectors, the attractiveness of the environment, the presence of pedestrians, the condition of the sidewalk, and the existence of obstacles are highly relevant in explaining pedestrian demand behavior. The hybrid model indicates that sidewalk width and the presence of obstacles impact the perception of <em>comfort</em> and <em>safety</em> in both sectors. On the other hand, the presence of pedestrians has a positive effect on <em>safety</em> but a negative effect on <em>comfort</em>. These results show that physical attributes of the built environment influence pedestrian perceptions. Improvements in pedestrian infrastructure and the building environment are necessary to encourage walking as an active mode of transportation. They include promoting mixed land use, widening sidewalks, removing obstacles, and maintaining them to ensure continuity and good condition.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"163 ","pages":"Pages 358-369"},"PeriodicalIF":6.3,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143173797","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}

To address this issue, this paper introduces a refined methodology aimed at accurately representing passenger waiting times and estimating the distributions of passenger arrival patterns at bus stops, with a focus on low-frequency suburban buses, considering their schedule-reading behaviors. First, we conducted stated preference (SP) and revealed preference (RP) surveys to capture the factors affecting passengers’ arrival behaviors, revealing that bus vehicle headway and bus arrival punctuality (quantified as the standard deviation of arrival time deviations, SD-BATD) significantly influence passenger behavior. Second, we developed models to assess the proportions of schedule-reading passengers (SR-passengers) and their average waiting time (AWT) as well as standard deviation (SD-WT). By treating AWT and SD-WT as independent variables, we then characterized the arrival patterns of both SR-passengers and schedule-neglecting passengers (SN-passengers) using maximum extreme value and uniform distributions, respectively. Additionally, we conducted numerical experiments on bus headway optimization to validate the operational implications of the proposed model for bus services. The results demonstrate that the AWT model significantly reduces bus operation costs by up to 15.7% compared to the traditional assumption that AWT = 1/2 headway. This effect is particularly pronounced for routes characterized by lower demand and higher speeds, which are typical of low-frequency suburban buses. Furthermore, this paper highlights the importance of accurately estimating the passenger waiting times considering passenger schedule-reading behavior in optimizing bus services.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"163 ","pages":"Pages 310-322"},"PeriodicalIF":6.3,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143174760","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}

This system aims to address the UDC localization problem. Deliveries are performed by platoons of electric and automated vehicles in which the leading one is driven while the others move driverless. Each platoon travels from the Urban Distribution Centre (UDC) to a specific place on the border of the city centre, named Split Up Location (SUL), where the platoon is divided. Then each vehicle, except the leading one, carries out the last mile deliveries in an automated way. During this time, the driver can relocate where required. After finishing deliveries, vehicles come back to the same SUL and reassemble in a platoon, then the platoon comes back to the UDC. The system design has been addressed as a two-echelon Vehicle Routing Problem with satellites, where SULs play the role of satellites and the UDC plays the role of the depot. Thanks to the fact that SULs have a fixed position, they are located in strategic positions of the urban area, it has been possible to simplify this problem and sub-divide it into two sub-problems: a minimum path problem from the UDC to SULs, and a multi-depot CVRP (Capacitated Vehicle Routing Problems) from SULs to receivers, where SULs play the role of depots. A simulator modelizes the activities of each platoon, each vehicle and each driver and it allows to evaluate, dynamically, the number of vehicles required to operate the system and the timetable of driver activities. The proposed transport system provides significant savings in terms of: energy consumption, CO<sub>2</sub> and PM<sub>10</sub> emissions, and costs. These savings are also due to the UDC utilization that allows a strong reduction in the number of delivery trips, thanks to a reorganization of packages in order to increase the vehicle load factor. However UDCs still record a low usage: as a result, policies of public administrations should be oriented to improve the UDC utilization.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"164 ","pages":"Pages 42-59"},"PeriodicalIF":6.3,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143184","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 the CISFN adapted rapidly to the increasing air cargo volume and continued to expand.

The densification of the H&S system provided more alternatives for the hub cities, and consequently the robustness of the system has improved.

This perspective tends to overlook the equally important social dynamics and institutional factors. Socio-ecological resilience theory fills this gap by viewing disruptions as opportunities for renewal, innovation, and transformation, recognising that systems operate in dynamic, non-equilibrium states where change is inevitable and unpredictable. However, its application in transport studies has been limited due to the complexity of empirical implementation. This paper utilises the Multi-Level Perspective (MLP) to offer a framework for understanding transport systems as complex socio-technical networks—encompassing artifacts, infrastructure, human actors, regulations, and cultural meanings. MLP's nested, layered ontology helps conceptualise the complexity and evolution of transport systems. Using Hong Kong's dockless bike-sharing system during the social movements and pandemic, this study explores how individual, community, and organisational resilience interact across scales. It shows how institutions both shape and are shaped by human agency, with interpretive flexibility allowing individuals to adapt institutional rules to personal contexts. The structuration of parking practices—shaped by voluntary digital communities managing bike parking and formalised through organisational and regulatory frameworks—illustrates how multi-level resilience arises through interactions among diverse actors, rather than from the mere accumulation of individual actions. While higher degrees of structuration, shaped by the scale of fields and number of actors reproducing them, foster stability, they can also perpetuate social exclusion, highlighting the need for equitable policies that balance individual responsibility with inclusive institutional strategies.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"163 ","pages":"Pages 247-261"},"PeriodicalIF":6.3,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143174280","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}

However, these studies often treated all roads as a single category. In reality, roads can be classified based on their mobility and accessibility. In a recent empirical study, a U-shaped relationship was identified between the road death-to-injury (DTI) ratio and the road mobility-to-accessibility (MTA) ratio. This finding suggests that as the availability of road options increases (encompassing both high-mobility and high-accessibility roads), the DTI ratio decreases. Conversely, in situations with fewer road options, the DTI ratio tends to rise. The underlying reasoning is that more road options reduce the potential for vulnerable and less vulnerable modes of transportation to mix and interact with, improving overall safety. While prior research has examined the direct impact of MTA on the DTI ratio, there exists a gap in understanding the indirect impact of MTA to the DTI ratio. This study utilizes two-equation panel regression models to examine the direct and indirect impacts of MTA on the DTI ratio. The direct impact examines how MTA directly influences the DTI ratio, whereas the indirect impact explores how MTA impacts economic performance through export-led development and the subsequent influence of economic performance on the DTI ratio. The results of this study showed that there is a direct and indirect relationship between the MTA and the DTI ratio. The expected threshold level of the total impact of MTA, which is the sum of its direct and indirect impacts on the DTI ratio, can rise or fall depending on economic performance levels under high export-led growth conditions.
