The research initially employs a fixed-effects panel model to confirm the overall positive impact of Shanghai Port on Yangtze River inland ports. Subsequently, using Panel data model with individual-specific slopes, this study reveal that Shanghai Port positively affects each inland port, but the magnitude of this impact varies significantly. The research further employs a panel threshold regression model to dissect the mechanisms through which Shanghai Port influences inland ports in terms of geographical, operational, and economic distances. In terms of geographical distance, the influence of Shanghai Port on the throughput of Yangtze inland ports diminishes as the navigational distance increases. Notably, inland ports located downstream on the Yangtze River are the first and most impacted, marking the downstream area as an early influencer in the port regionalization process. As to operational distance, Shanghai Port exerts a stronger influence on inland ports with higher throughput levels, as opposed to those with lower throughput. With respect to economic distance, inland ports in cities with higher economic development are found to be less influenced by Shanghai Port compared to those in less economically developed regions. This nuanced understanding provides invaluable insights into the interconnectedness of major gateway ports and their inland counterparts.</p></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"157 ","pages":"Pages 10-19"},"PeriodicalIF":6.3,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142002069","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}

Drawing from both quantitative and qualitative data from the 2021 Montréal Mobility Survey, this paper analyzes public perceptions towards two transport projects—a light-rail transit (LRT) and a bus-rapid transit (BRT). Quantitative statements pertaining to five project impacts were compared between the two projects. Both projects had high levels of agreement (between 67% and 80%) regarding expected regional and environmental impacts, but agreement levels were lower for expected neighborhood, cultural, and residential displacement impacts (between 49% and 30%). To contextualize the quantitative findings, qualitative data were pulled from open-ended questions for both projects and analyzed using an applied-thematic-analysis approach. The qualitative responses focused primarily on negative perceptions, providing insight into potential factors contributing to the erosion of social acceptability. Our analysis of open-ended questions underscored contrasting perceptions between the two projects in terms of improvements in accessibility to destinations (minimal for the BRT vs noticeable for the LRT), governance (transparent for the BRT vs opaque for the LRT), consultation processes (adequate for the BRT vs insufficient for the LRT), and construction impacts (lengthy and disruptive for the BRT vs rapid for the LRT). These contrasting quantitative and qualitative results highlight the need for mixed methods when assessing public perceptions. Findings from this paper can be of benefit to practitioners and policy makers as they aim to ramp up efforts to expand public-transit systems.</p></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"157 ","pages":"Pages 34-45"},"PeriodicalIF":6.3,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0967070X24002294/pdfft?md5=7a9cdfb78b96deb2218fcbb0936e85e6&pid=1-s2.0-S0967070X24002294-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142012042","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}

Although there has been a range of progress at the state level, many gaps need to be filled to include Complete Streets in asset management policies and improve practices, and there is no national guidance or comprehensive plan to achieve this. This study developed a roadmap to fill those gaps regarding infrastructure asset management. To create this roadmap, the study completed the following tasks: 1) develop and implement a survey supplement it with in-depth surveys with several agencies, 2) synthesize survey outcomes, 3) identify current statuses, challenges, and needs, and 4) develop a roadmap for Complete Streets infrastructure asset management. All 50 state transportation departments participated in the national survey. This paper synthesizes the outcomes of the surveys and literature review. The survey results showed that many agencies have some Complete Streets guidance (39/50), but only seven agencies have Complete Streets performance measures and no agency has bike/ped specific condition measures. The three primary challenges are: 1) inadequate funding related to organizational structure 2) the need for performance measures, and 3) the need for improved data accessibility, collection methods, and management techniques. The proposed Roadmap to Complete Streets Asset Management Policies includes pathways for 1) asset management performance measure development and 2) data collection and analysis. The roadmap organizes existing needs into a step by step framework for incorporating Complete Streets into infrastructure asset management programs and policies. Policy implications include the need for network-level performance measures and targets that the entire agency is responsible for, improved data collection techniques, and internal structural adjustments to encourage collaboration and data sharing within departments of transportation.</p></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"157 ","pages":"Pages 86-97"},"PeriodicalIF":6.3,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142049241","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 inland waterway is the main transportation corridor with a relatively low adoption of green technologies, which produces heavy air pollution in inland cities. This paper investigates the ship deployment problem for an inland river carrier considering the adoption of green fuel and green technologies for a given ship fleet. A non-linear programming (NLP) model is proposed to jointly optimize green technology adoption, sailing speed, and routing problems while considering two unique characteristics of inland river shipping, including the non-identical streamflow and the speed limits on each shipping leg. The analytical propositions reveal the optimal operation strategy of the inland river ship fleet, and a column generation-based algorithm is further designed to solve the proposed model. By jointly investigating the ship operation strategy and sulphur emissions, we find the following management insights: Firstly, the ship would have a lower willingness to invest in shore power (scrubber) if it installed scrubber (shore power). The higher streamflow and looser speed limits would reduce the spillover effect of green technology adoption. Secondly, emissions will spillover from ports to river legs if only shore power is provided. Our findings provide valuable insights for policymakers to promote complete green technology adoption to achieve comprehensive abatement of the entire inland river.</p></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"157 ","pages":"Pages 46-56"},"PeriodicalIF":6.3,"publicationDate":"2024-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142045066","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 is particularly concerning for the millions suffering from opioid use disorder (OUD) since treatment for OUD can require in-person visits daily or a few times a week. To better understand how public transit influences access to treatment for OUD, we observe distances among opioid treatment programs (OTPs), buprenorphine providers, and public transit stops in the U.S. We also investigate the possible role of micromoblity, specifically bikesharing and e-scooters, in filling these transportation gaps. Results show that in urban counties, 48–91% of buprenorphine providers and OTPs are within possible walking distance (i.e., 0.4–1.4 km) of public transit stops, suggesting a high degree of heterogeneity in public transit access even among urban counties. In rural counties, only 5–40% of buprenorphine providers and OTPs are within possible walking distance of public transit stops. Given that many micromobility programs are in urban areas, they could complement public transit in urban counties where public transit runs less frequently, but not in rural counties. We also find that, on average, the odds an OTP or a buprenorphine provider is within walking distance of a public transit stop decreases outside the large central metro counties, as well as in counties that have a greater percentage of people with lower educational attainment. Affordable transportation options will continue to limit treatment options for people suffering from OUD, especially outside major metropolitan areas, unless public transit or other transportation innovations are expanded or telemedicine becomes more accessible.</p></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"156 ","pages":"Pages 152-163"},"PeriodicalIF":6.3,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141948274","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}
