The earliest models focused on traditional production functions that do not account for the impact of multiple factors, while later models employed Stochastic Frontier Analysis (SFA) and Data Envelope Analysis (DEA). The model employed here is a Vector Error Correction Model (VECM), which takes into account the long-run and short-run relationships among several variables: monthly container moves, gross labour hours, crane and straddle carrier operating hours and container yard storage capacity. Impulse response analyses find that a one standard deviation in monthly container moves has a significant effect on equipment efficiency usage and yard storage capacity, important factors that shipping lines are likely to give serious consideration when choosing a trans-shipment terminal. The findings of this model suggest that in order to improve efficiency the time containers remain in-transit on the terminal has to be contained because this affects storage capacity utilization and significantly impacts other variables such as machine hours and labour hours.","PeriodicalId":432405,"journal":{"name":"Transportation Science eJournal","volume":"22 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113989550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to previous analyses of accessibility, this study uses travel time estimates derived, to the extent possible, from actual observations of network performance by time of day. A set of cumulative opportunity measures are computed with transportation analysis zones (TAZs) as the unit of analysis for 1995 and 2005. Analysis of the changes in accessibility by location over the period of study reveals that, for the majority of locations in the region, accessibility increased over this period, though the increases were not uniform. A \"flattening\" or convergence of levels of accessibility across locations was observed over time, with faster-growing suburban locations gaining the most in terms of employment accessibility. An effort to decompose the causes of changes in accessibility into components related to transportation network structure and land use (opportunity location) reveal that both causes make a contribution to increasing accessibility, though the effects of changes to the transportation network tend to be more location-specific. Overall, the results of the study demonstrate the feasibility and relevance of using accessibility as a key performance measure to describe the regional transportation system.","PeriodicalId":432405,"journal":{"name":"Transportation Science eJournal","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120939978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The applied mechanism combines the merchant and regulatory approaches to attract investment into transmission grids. It is based on rebalancing a two-part tariff in the framework of a wholesale electricity market with locational pricing. The expansion of the network is carried out through the sale of financial transmission rights for the congested lines. The mechanism is tested for 14-node and 17-node geographical coverage areas of PJM. Under Laspeyres weights, it is shown that prices converge to the marginal cost of generation, the congestion rent decreases, and the total social welfare increases. The mechanism is shown to adjust prices effectively given either non-peak or peak demand.","PeriodicalId":432405,"journal":{"name":"Transportation Science eJournal","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127984303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We excludeemployer-provided and residential parking. We demonstrate that cruising time is, on average, 36seconds per car trip. Car drivers appear to choose their cruising time in line with economictheory: cruising time increases with travel duration as well as with parking duration, but fallswith income. We also find that cruising is more common with shopping and recreation than forwork-related activities. Cruising has a distinctive pattern over the day with a peak in themorning, so the order of arrival is essential to parking.","PeriodicalId":432405,"journal":{"name":"Transportation Science eJournal","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121559982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We are particularly interested in water tarification in a poverty context where a subsistence level of water has to be allocated to each household. Our approach is \"semi-welfarist\" to the extent that we analyze second-best pricing schemes that may be applied in practice due to \"fairness\" or other, non-welfarist considerations. In our theoretical model we compare a modified Coase-tariff and a progressively increasing block tariff with respect to water consumption, water expenses and utility levels. When we impose cost coverage on the water utility, there are clearly adverse effects on the \"almost poor\" by introducing a progressive tariff. This result is supported with a numerical application using real data from Bangladesh: progressive tariffs may fail to achieve \"fair\" cross-subsidization of low-income groups.","PeriodicalId":432405,"journal":{"name":"Transportation Science eJournal","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121220841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we conduct a stochastic analysis of guided tours for tourists during the slack season. We first delineate a general model that accounts for the common features of guided tours to city attractions and to other scenic locations. Second, we determine the long run fraction of demand that is lost to the firm providing the guided tours. Third, we ascertain the long run fraction of time that the guided tour providing firm is unable to satisfy the demand for such tours. Finally, we use the stationary Poisson process and show how our previous two general results might be used to shed practical light on the slack season provision of guided tours to tourists.","PeriodicalId":432405,"journal":{"name":"Transportation Science eJournal","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130319622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the new regulations, road transport undertakings must organise the work of drivers in a way that drivers are able to comply with the regulations and can be made liable for infringements committed by the drivers. Although of particular importance in long-distance haulage, regulations on working hours of truck drivers have only received very little attention in the scheduling literature. This paper presents a method for scheduling work weeks of truck drivers which fully considers regulation (EC) No 561/2006 for journeys made on roads in the European Union. It is proven that, given a sequence of locations to be visited within specified time windows, the approach finds a schedule complying with the regulation if such a schedule exists.","PeriodicalId":432405,"journal":{"name":"Transportation Science eJournal","volume":"530 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126500784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
