However, the construction of dry ports is a long-cycle and high-consumption project, and it is necessary to coordinate the interests of all parties at the early stage of construction and fully consider the impact of the completed dry port on the seaport and the local economy. Therefore, this paper considers two Port Operators A and B, and Port Operator A decided to invest in dry port to upgrade and expand. We investigate under what conditions Port Operator A should establish what scale of dry port in the face of the increasingly complex competitive environment and shippers' port selection behavior. For that, we take two seaports as a kind of network product, and analyze the necessity and feasibility conditions for Port Operators to invest in the construction of dry ports by applying the economic theory of network effect on the basis of the improved Hotelling model. The results show that even if the network effect is low, if the shippers bear a low unit transportation cost, the construction of dry ports can not only help Port Operator A to enhance competitiveness but also promote the development of Social Welfare. If the network effect intensity is high, Port Operator A can realize rapid expansion by taking advantage of the high service quality of dry ports, but the scale of dry port should be controlled within a certain range.</p></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 103987"},"PeriodicalIF":5.7,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142239301","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}

Rail systems, including light rail, metro, urban, suburban, and long-distance trains, are the key fixed structural elements of any transport system that provide faster access for both shorter and longer trips and are regarded as a more efficient and environmentally friendly option to move a larger number of passengers than road transport. However, it is not feasible in terms of investment and financial sustainability to provide rail services everywhere, especially in rural zones. Thus, connectivity with all the other available (active and motorized) modes is crucial to improve accessibility and reduce inequities. In this paper, we developed a methodology to quantify and contrast the access to the existing rail services between zones of a metropolitan area and corresponding inequities. We considered not only the usually analyzed active modes, pertaining to a certain level of proximity to the rail stations, but also motorized modes (e.g., car and bus) that can enable the connection to rail services where these are not easily accessible by walking or cycling. First, the accessibility to the existing rail stations is quantified using place-based gravity measures, considering the travel times for the complementary modes with and without incorporating the stations' attractiveness, measured by service frequency. Second, the global inequity levels of the spatial distribution of the rail network in the metropolitan area are evaluated using the Gini index. Third, local inequities, at a scale of small census blocks, are measured considering the access (supply) and the population (potential demand). While the local-scale analysis allows to identify the most unfavored zones, the global inequities by complementary modes aim to inform targeted strategies to improve the integration of those modes with rail services. The methodology was applied to the Metropolitan Area of Porto, Portugal, where we observed a non-uniform distribution of rail services and a decrease in access towards the periphery. However, considering the population living in each zone, both underserved and well-served zones are mostly present in the most populated/central areas.</p></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 104007"},"PeriodicalIF":5.7,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0966692324002163/pdfft?md5=11df0bb4fddd20bbb442bc0fabcc45df&pid=1-s2.0-S0966692324002163-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142239302","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}

The aim of this research was to determine the nature and scale of these transformations over a period of about 10 years, with the intent to find possible geometric regularities and taking into account the spatial relationships between the highway interchanges under study and the existing network of cities. The analysis of the highway interchanges were quantitative, expressed by the quantitative growth of new buildings located in the vicinity of a given junction, as well as in spatial terms – examining the geometric distribution of the placement of new buildings and identifying the zones of the most dynamic spatial transformation for each interchange/junction. The findings were individually referenced to each interchange, after which they were aggregated to the cities that these junctions or groups of junctions serves. The study was based on original field research and a comparative analysis of satellite imagery that depicted the site development of the space investigated in the period preceding the construction of the junctions and at the time of the study. GIS and CAD tools, as well as a review of the literature and the state of the art were used. The results presented contribute a number of important insights into the scale and nature of the transformation of the areas around the junctions under study. They also allow for general conclusions to be drawn concerning the impact of highway corridors on space, particularly that of suburban areas, and the impact of the location of highway interchanges on the transformation of the functional and spatial structure model of cities.</p></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 104005"},"PeriodicalIF":5.7,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S096669232400214X/pdfft?md5=a0b632d252cc32831b23b8af1ca6f0c0&pid=1-s2.0-S096669232400214X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142239299","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}

Basic economic theory suggests that as gasoline prices rise, there tends to be a decrease in the consumption of gasoline due to the substitution and income effect, leading to a reduced use of private motor vehicles by commuters who may opt for relatively cheaper modes of transportation for their daily commutes. Using data from the American Time Use Survey spanning from 2003 to 2019, coupled with state- and year-specific gasoline prices, the study reveals a positive relationship between gasoline prices and daily commuting time. Furthermore, gasoline prices are also associated with the choice of commuting modes. Higher gasoline prices are negatively related to the proportion of commuting time using private motor vehicles and positively related to the proportion of commuting time using public transit, walking, and cycling. Heterogeneity analysis reveals that the association between gasoline prices and the proportion of commuting time using public transit and walking varies depending on the rural status of commuters. The results of this paper can be used to formulate pricing policies in order to change the daily travel choices of commuters, mitigate greenhouse gas emissions, and develop a less fuel-dependent transport sector in the US.</p></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 104006"},"PeriodicalIF":5.7,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0966692324002151/pdfft?md5=b09d31fae5958b252b4cea1f0b4d7167&pid=1-s2.0-S0966692324002151-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142239300","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}

This study integrates data about the jobs-housing relationship, road network configurations, public transport availability, and real-time traffic conditions during peak hours to evaluate the commuting feasibility and performance of green travel modes (walking, cycling and public transport) and explore the potential determining factors. In the context of the x-minute city, the green travel commuting feasibility (GTCF) indicator measures the percentage of the working population who can commute via green travel modes within specific x-minute thresholds. 15, 30, 45 and 60 min have been considered. In comparison, the car travel commuting feasibility (CTCF) indicator is developed to evaluate the corresponding commuting performance by car. Nanshan district of Shenzhen in China is taken as a case study. Results show that distinct gaps exist between GTCF and CTCF. Public transport performs well only for long-distance (&gt; 8 km) commuting trips, and cycling does well for short (&lt; 3 km) and medium-distance trips. Geographically, areas with large differences of GTCF and CTCF are identified for improving green travel modes with priority. Potential factors influencing GTCF are explored with a regression model and case-based analysis. Smaller street blocks, bus route realignment and better jobs-housing balance should be targeted. Designing cycling short-cuts and public transport routes that avoid traffic jams are also recommended to promote green commuting. The findings demonstrate that real-time trip-planning information is of great value in evaluating the commuting feasibility of multimodal travel and identifying influential factors for achieving the x-minute city.</p></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 104003"},"PeriodicalIF":5.7,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142228434","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}

Existing methodologies, often focused on DBS trips around metro stations or limited by scant datasets, overlook the pressing need for a method to discern large-scale DBS-metro trips as DBS becomes a standard feeder mode for metro trips and the yet unexplored spatial lag effects of the built environment on DBS-metro interactions. To bridge these gaps, we develop a method integrating smart card records and DBS data, revealing a comprehensive trip chain encompassing both metro and DBS. Our application of association rule algorithms to large-scale data provides detailed spatial insights into feeder trips. We employ a network-adjacency-based partial spatial Durbin model, tailored with a negative binomial regression for count data and maximum likelihood estimation for continuous data. Analysis from Shenzhen reveals: (1) A strong correlation is observed between the count of trips using cycling as a feeder mode (COUNT) and the location of stations within the metro network structure. Notably, the COUNT shows more significant aggregation when compared to the ratio of DBS-metro transfer trips to the total metro trips at each station (RATIO); (2) significant influence of both local and adjacent spatial variables of the built environment on the RATIO and COUNT of cycling trips; (3) specific factors like feeder station location, city center proximity, Street greenness view situation, and road intersection density significantly influencing the cycling feeder mode for metro trips; (4) Moreover, areas with more urban villages and industry appeared to contribute to the cycling feeder mode for metro trips, both in terms of RATIO and COUNT. This study underscores the necessity of fostering a conducive built environment to leverage DBS's potential to bridge the last-mile gap.</p></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"121 ","pages":"Article 103995"},"PeriodicalIF":5.7,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142148080","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 research proposes the ‘node-place-network-city’ framework, an innovative extension of the traditional ‘node-place’ model, to analyse station area development. Focusing on 123 HSR station areas in the Yangtze River Delta as of 2018, this research employs spatial big data to explore the intricate relationships between various city and network indicators and station area development. Unlike previous studies that have typically simplified station area development and treated the relationships as linear, this study adopts a decision tree model. This method effectively identifies diverse typologies of HSR stations and facilitates the formulation of tailored development strategies for each type. This research significantly contributes to the theoretical understanding of HSR station area development and provides valuable and actionable insights for urban planners and policymakers. It marks a step forward in comprehensively assessing and guiding the development of HSR station areas, thereby offering a robust framework for both academic research and practical application in spatial planning.</p></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"120 ","pages":"Article 103993"},"PeriodicalIF":5.7,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142130042","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}
