An integrated sea–Land Transportation system model and its theory
Transportation Research Part C: Emerging Technologies, 2009Co-Authors: Xinlian XieAbstract:Abstract To enhance the efficiency of intermodal Transportation for large quantities of goods, the current sea–Land Transportation system has been reviewed and systematically analyzed, and a bottleneck is pinpointed in the linkage or goods transfer between the waterway and railway. The bottleneck impacts the efficiency of the goods through Transportation combining the two modes. To eliminate the existing bottleneck and inefficiency towards intermodality, a new type of flexible double-rail track has recently been invented together with innovations both in trestle bridges and in train ferries. The outcomes of the research in progress show that the flexible double-rail track is feasible from the viewpoints of both geometry and engineering mechanics, it can be used to improve the compatibility of a trestle bridge with various types of train ferries and hence it can support the development of train ferries on a large scale. Based on the innovations, an integrated sea–Land Transportation system model is proposed as a systematic solution, which is expected to effectively overcome the existing bottleneck and to enhance the efficiency of the whole sea–Land combined Transportation. Further research on this system model and its major components is also addressed in the paper.

Accessibility and urban spatial connections of cities in the Silk Road Economic Belt based on Land Transportation
Progress in geography, 2015Co-Authors: Cao XiaoshAbstract:Analyzing accessibility and urban spatial connection of the Silk Road Economic Belt is the basis for implementing the strategy of the Silk Road Economic Belt and facilitating cooperation and achieving mutual benefits of the region along the economic belt. Based on GIS spatial analysis technology, the spatial pattern of raster grid accessibility for the Silk Road Economic Belt is studied and the states of urban spatial relation are simulated using Land Transportation network in this research. The result shows that the spatial distribution of urban accessibility in the Silk Road Economic Belt presents clear spatial characteristics of aggregated distribution along the main corridors. Average accessibility of urban nodes as measured by travel time is 16.25 hours, and the areas accessible within 2 hours occupies 10.6% of the total area. Most of the areas with the lowest accessibility are found in the margins of the deserts, with the worst accessibility of 171 hours. Xi'an as the gateway city connects the five provinces of Northwest China and other countries, regions, and cities of the Silk Road Economic Belt. The spatial connections of Central Asian countries within e national boundaries and with cities outside are relatively weak. The Silk Road Economic Belt is forming four main axes. In the future strategic development of the Silk Road Economic Belt, it should consider to implement a "point-axis" growth structure to drive the development of corridors and central cities(dense urban area).

energy demand emissions forecasts and mitigation strategies modeled over a medium range horizon the case of the Land Transportation sector in metro manila
Energy Policy, 2014Co-Authors: Mohammad Ahanchian, Jose Bienvenido M BionaAbstract:Transportation contributes to resource depletion and has other negative impacts on the environment. The present study presents models of energy demand and environmental emissions for the Land Transportation sector in Metro Manila, Philippines from 2010 to 2040 using the “Long Range Energy Alternatives Planning (LEAP)” tool. The study projected energy demand and CO2, CO, HC, NOx and PM10 emissions for Business-As-Usual (BAU) and alternative scenarios and compared the results while aiming to determine optimal Transportation policies to reduce energy demand and emissions. The results indicated that the adoption of EURO 4 emission standards provides the greatest reduction in energy use at 10.8%, while the best cases for the various gas emissions were split among different options. In addition, a combination of all of the alternatives is expected to lower energy use by 27.8% and to reduce CO2, CO, HC, NOx and PM10 by 30.3%, 60.3%, 59.0%, 48.2% and 66.4%, respectively. The analytical framework employed herein could be applied to other cities to evaluate and prioritize strategies to reduce future energy requirements and emissions.

OGP Land-Transportation Safety Recommended Practices Reduced Fatalities Significantly
Journal of Petroleum Technology, 2010Co-Authors: Karen BybeeAbstract:This article, written by Assistant Technology Editor Karen Bybee, contains highlights of paper SPE 126520, ’How OGP Land Transportation Safety Recommended Practices Led One Company To Significantly Reduce Fatalities in Just 18 Months,’ by David Allison and Mihai Frasineanu, OMV-Petrom, originally prepared for the 2010 SPE International Conference on Health, Safety, and En vironment in Oil and Gas Exploration and Production, Rio de Janeiro, 12-14 April. The paper has not been peer reviewed. The full-length paper demonstrates that the application of the elements of the International Association of Oil and Gas Producers (OGP) Land-Transportation Safety Recommended Practices was instrumental in reducing traffic-related fatalities to zero over an 18-month period. The full-length paper describes the gradual step-by-step development of a company Land-Transportation standard and the key elements applied so far, and it shares the learning’s of the company in Romania. Introduction Driving-related incidents are the largest single cause of fatalities in OGP member-company operations, accounting for approximately 25% of the fatalities worldwide for the past 10 years. Between 1998 and 2008, OGP member companies reported 313 fatalities among employees and contractors engaged in work-related driving activities. An OGP task force produced “Report Number 365, Land Transportation Safety Recommended Practice” with the stated purpose of helping reduce the number of, and eventually eliminating, serious road-traffic accidents and fatalities by providing guidance on how to implement Land-transport safety elements into a structured management system. The document was published in April 2005. An exploration and production company in Romania, with a fleet of more than 3,000 vehicles, had traditionally recorded automobile-accident fatality rates far in excess of peer companies within the oil and gas domain. The internal statistics were in line with the average Romanian road-traffic fatality rate, which in 2006, was 32% above the European Union average rate and increasing. In an effort to reverse this alarming situation, the company put considerable additional resources into the implementation of the OGP Land-Transportation Safety Recommended Practices in 2008, with the objective of reducing (and eventually eliminating) the high number of serious road-traffic-related incidents being suffered by its workforce, involved contractors, and the general public. The company started applying the OGP recommended practices by the introduction of a company standard, “Health, Safety, Environment, and Quality Requirements for Transportation Activities”, which was based on the recommendations contained in the OGP document. From a level of almost zero compliance in 2007, the company moved rapidly forward and as a result encountered many challenges that had to be understood, defined, and managed in a dynamic way. As the elements of the recommendations were implemented and momentum against the initial reluctance of the organization grew, many lessons were learned that potentially will assist other organizations considering the adoption of the OGP approach to avoid similar problems.

applications of vehicular communications for reducing fuel consumption and co 2 emission the state of the art and research challenges
IEEE Communications Magazine, 2012Co-Authors: Chakkaphong Suthaputchakun, Zhili Sun, Mehrdad DianatiAbstract:Environmental problems, such as pollution, become more serious year after year. One of the major causes is high fossil fuel consumption with CO2 emission. In 2009, 23 percent of CO2 emission globally came from Land Transportation systems, which is equal to 7000 million tons of CO2. This large amount of gas pollution should be reduced to slow down global environmental problems. Reduction of fuel consumption and CO2 emission in Land Transportation systems, which will have immediate positive economical and environmental impact, has become an important part of green technologies to alleviate global warming due to human activity. Intelligent Transportation systems, which aim to use information and communication technology in the Transportation systems, are considered to be a major enabler for the future green ITS. This article aims to provide a survey of the latest published applications based on vehicular communications as well as the envisaged technical challenges in this research area.
