Airlines resorted to many ways—including code-sharing—in response to competitive pressures. This article is a retrospective study on the load factor effects of the largest domestic codeshare partnership established in 2003—between Delta, Northwest, and Continental airlines. After controlling for aircraft configuration, carrier, and market characteristics, we find evidence that code-sharing improves the partners' load factors relative to other carriers in all markets combined. However, we find statistically significant negative (positive) codeshare effects on load factor in markets where the codeshare partners competed (did not compete) prior to code-sharing.","PeriodicalId":46529,"journal":{"name":"Transportation Journal","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43876077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study, conducted in France, aimed to influence car users to use public transport. Compared to previous VTBC programs, this one proposes a more qualitative accompanying framework to participants. Car users participated in the program based on a committing recruitment, an individualized counseling meeting, and a free monthly travel card on public transport, altogether creating a strong commitment context for long-term behavior change. Results reveal the effectiveness of the method since a majority of test travelers continue to use public transport up to three months. Moreover, the program increases the positive attitude toward the bus and “mobility capital” of participants.","PeriodicalId":46529,"journal":{"name":"Transportation Journal","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49077640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a comprehensive methodology to identify initiatives with the most potential in terms of cost and efficiency for the fuel distribution process in urban areas, and then to assess impacts of such initiatives in terms of environmental and economic sustainability. Results indicated off-hours deliveries as having a higher potential to increase sustainability in fuel distribution within city borders. Therefore, an application of the proposed methodology is presented to assess results of a live experiment of off-hours deliveries held in a fuel-distribution process in a mega-city in comparison to daytime deliveries, which is companies’ standard practice. Several positive results were observed during off-hour deliveries, such as reduction in fuel consumption, reduction in the emission of air pollutants and greenhouse gases, reduction in travel time, increase in average operational speed as well as the possibility of carrying out two trips with the same vehicle per day leading to a reduction in expenses with drivers when there is an increase in daily truck deliveries. Although the case assessed was conducted during the Olympic Games of Rio de Janeiro, the method can be applied in any other mega-city.","PeriodicalId":46529,"journal":{"name":"Transportation Journal","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47829433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Bayesian network is constructed with the 35 indicators selected, which are classified into five different categories: international trade and transport, economy and finance, population and social condition, environment and energy, and institutional and political. It is found that capacity of liquefied natural gas regasification terminals under construction and modal distribution of cargo transport by inland waters are the two root nodes of the network. In addition, the variables of transport and international trade and economy and finance become the most important in the decision to implement liquefied natural gas as marine fuel, while those of environment and energy and population and condition are the most dependent on the network.","PeriodicalId":46529,"journal":{"name":"Transportation Journal","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42561398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These decisions are crucial in emergency humanitarian logistics management since the response time to affected areas dramatically influences the survival rate and timely availability of relief items. This article considers many real-life aspects to deal with the problem realistically. A framework based on Geographic Information System (GIS) is presented that takes into account widths and structures of different types of infrastructure (roads, tunnels, and bridges), the survivability of infrastructure according to its spatial proximity to a potential disaster, and legal speed limits in the pre- and post-disaster decision processes. A case study was carried out for an earthquake disaster scenario in Erzincan province of Turkey and various scenarios were generated to analyze the solutions under different conditions.","PeriodicalId":46529,"journal":{"name":"Transportation Journal","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49279658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lam","doi":"10.5325/transportationj.58.2.v","DOIUrl":"https://doi.org/10.5325/transportationj.58.2.v","url":null,"abstract":"Global Shipping and Port Competitiveness: The Traditionalist and Supply Chain Perspectives Global shipping is a volatile industry, but it is rapidly recovering from the 2016 market which saw the consolidation and bankruptcy of several shipping lines, including the Korean giant Hanjin Shipping. This forced global shippers and carriers to rethink how they are going to remain competitive in a market that still has significant overcapacity in 2018, and for the foreseeable future. Luckily, 2017 was a good year financially for the large carriers with improving operating margins. Extending the first special themed issue in summer 2018, this second special issue on global shipping and ports focuses on how shippers and carriers are becoming more flexible in their strategies and operations to create new competitive advantages. It addresses issues with the methods used to study ports, strategic impacts on large and small vessels, hinterland constraints to ports, as well as the emergence of supply chain theory to guide port priorities. The lead article by Chang and Talley examines port competitiveness from the perspective of traditional port efficiency and the more contemporary supply chain viewpoint. It points out that there are some critical methodological issues in current port literature that may explain contradictory findings. They recommend directions for future research to resolve many of these issues. The second article by Yalcin, Chakravorty, and Yun focuses on the contemporary perspective to discuss how supply chain agility and ambidexterity concepts can be used to improve port competitiveness through the theoretical lens of the Balanced Theory of Port Competitiveness. They find that both explorative and exploitive practices are beneficial to port competitiveness. The third article by Lu and Yeh examines the impact of larger container vessels on port agility, which leads to greater efficiency and profits, but may harm customer service and safety. They note how Europe and Asia differ in how they tend to prioritize competitive factors from the proliferation of mega container vessels. The fourth paper by Fliehr, Zimmer, and Smith focuses on hinterland access to ports that affects port operations and prices. In the context of Brazil, the authors examine how inefficiencies in farm-to-port logistics affect farm gate pricing.","PeriodicalId":46529,"journal":{"name":"Transportation Journal","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2019-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41772370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Second, we develop and test an econometric model of the determinants of motor-carrier exit. Using recent data derived from the Motor Carrier Management Information System database, we find that motor-carrier exit continues to be quite prevalent. This study also finds that motor-carrier crash rates are positively associated with the likelihood of exit from the industry, while fleet size and number of commodity segments handled by motor carriers are negatively associated with a carrier's likelihood of exit. Study findings also suggest that for-hire carriers are more likely to exit, and carriers handling hazardous materials are less likely to exit from the motor-carrier industry. The article discusses these findings, including managerial and public policy implications.","PeriodicalId":46529,"journal":{"name":"Transportation Journal","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2019-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47680826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, Mary Holcomb, Co-Editor-in-Chief of Transportation Journal, has finished her term and will be stepping down soon. Mary served as the Industry Note Editor for three years prior to being appointed as the co-editor of the journal. We very much appreciate her long-time service commitment to this journal. She has made a number of improvements for the journal. During her time as co-editor, the journal’s statistics, including paper submissions and impact factor, have improved considerably. She has done a great job for the journal, and she will be missed by all of the editorial team members. We wish her the best for the next chapter of her career. Second, David Swanson, a faculty member at University of North Florida, will be joining the journal’s editorial team as the new Co-Editorin-Chief, replacing Mary. David is a well-known transportation scholar, and we are delighted to have him join the board. He will be working closely with Mary for the next few months. Third, Carrie Ann Johnson, Assistant Editor of Transportation Journal, will be finishing her two-year term and will be stepping down soon. Carrie Ann has done a great job of assisting the editors for handling papers. After completing her term, she will be concentrating on her Ph.D. program at Iowa State University to finish her degree. We thank Carrie Ann for her help during the last two years, and we wish her the best for her future career. Fourth, Michael Belding, a Ph.D. student in history at Iowa State University, will be joining the editorial team as the new Assistant Editor. Michael will be working closely with Carrie Ann over the next few months to ensure a seamless transition. Michael is expected to serve in this role until summer of 2021. We welcome Michael to the editorial team. Fifth, it is time again to report the acceptance rate of the journal for the calendar year 2018. Our method of calculating the acceptance rate is to simply divide the total number of articles published in the year (2018) by the total number of papers submitted during the year (2018). Submissions of revisions are not counted as separate submissions to produce conservative acceptance rates. Using this method, the acceptance rate of research papers for 2018 was computed as 18.6%, or equivalently, rejection rate of 81.4%. In the past two years, the acceptance rates were 13.2% (2016) and 13.6% (2017), so the journal’s acceptance rate seems to have increased slightly. This is mainly due to the fact that we published a larger number of articles in 2018","PeriodicalId":46529,"journal":{"name":"Transportation Journal","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2019-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46886877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
