Top Research Papers on Transportation Engineering

FR U STR A TIO N S IN T R A N S P O R T A T IO N E N G IN E E R IN G As an officer in the American Public Works Association, it was my opportunity this past year to visit with engineers in city, county, an state work all over the country. If I were asked to identify the most common feeling of the many engineers with whom I visited, I would have to say that it was a feeling of frustration—frustration in being unable to complete much needed projects, to implement improvement programs, and in general, a frustration in the inability to get things done.

Programs of Study The Master of Science (M.S.) program is 32 hours, the Master of Engineering (M.E.) program is 30 hours, and the Doctor of Philosophy (Ph.D.) program is 64 hours. The specific course requirements are decided by the student in conjunction with the student's committee chair and graduate committee. However, the following courses (or their equivalent) are considered core courses for all programs of study: The Master of Engineering (M.E.) degree requires a minimum of 30 hours on the degree plan with approximately 9 of these hours being outside the student's major area of study. The...

Critical to building an American workforce with 21st century skills is the recruitment and graduation of students in science, technology, engineering, and mathematics fields. However, a nationwide lack of student interest and preparation in these fields results in a shortage of workforce talent. The transportation field is not immune to this shortage and faces significant issues related to attracting and retaining transportation professionals. Thus, it is crucial to raise awareness of opportunities available through the transportation profession with precollege students. The Transportation Eng...

The method of mathematically modelling a physical phenomenon involving fluid flow and solving it numerically using analytical prowess is known as computational fluid dynamics (CFD). Aerodynamics plays an important part in the manufacturing phase when an architect is tasked with developing a new vehicle, such as a winning racing car for the coming season. Aerodynamic processes, on the other hand, are difficult to quantify during the concept stage. Physical checks on product samples are typically the only way for an inventor to refine his designs.

Transportation Engineering Basics covers twelve of the most fundamental aspects of transportation engineering. This book presents practical experiences concerning such things as: 1) Traffic control devices; 2) travel times and delay studies; 3) spot speed studies; 4) sight distance and gap studies; 5) level of service analysis; 6) parking studies. Since this document is designed to be used as a text for both workshops and undergraduate courses, students or recent graduates can see how the concepts that they learned in school are applied to actual situations. Those with some experience in the f...

The transportation industry faces a growing shortage of professional engineers. A key strategy in solving this problem will be to encourage more civil engineering students to specialize in transportation while completing their undergraduate degree so that employers have a larger pool of likely recruits. This paper examines the factors that lead civil engineering undergraduates to specialize in transportation, as opposed to other civil engineering subdisciplines. The primary method used was a web-based survey of 1,852 civil engineering undergraduates. The study results suggest steps the transpo...

In what sounds like a throwback to the epic freeway boondoggles of the 1960s, Seattle will brutalize one of America’s great urban lakes with a $4.65 billion plan to replace the earthquake-vulnerable Evergreen Point Bridge. The existing bridge never won beauty contests, but its planned replacement is more than twice as wide, running well above the mountain-ringed Lake Washington on much larger, obtrusive pontoons (figure 4.1). It then broadens to the width of an airport runway as it hacks through the arboretum, a crown-jewel park, and paves over a hunk of Portage Bay, a beloved inlet that provi...

Deteriorating quality of the air, traffic congestions, and rising accident rates have all resulted from an ever-increasing number of vehicles in Indian cities. As a result of a variety of issues, current public transit systems often fall short or are considered unreliable. The present paper deals with multiple ITS architecture and to be specific four major parts of the ITS. These four major parts are Advanced Public Transportation System (APTS), Advanced Traveler Information System (ATIS), Advanced Traffic Management System (ATMS), and Emergency Management System (EMS). Thus, the framework and...

Hydrocarbon fuels microbiological contamination that affects not only the fuels quality but also equipment reliability takes place along with its flooding and contamination by mechanical impurities. Analysis of aircraft fuel systems and ground aviation fuel supply equipment operation was carried out. The necessity of national biocide additive developing that promotes substantially reducing the degree of aviation fuels microbial destruction was grounded.

In this article the notion of air cargo system operation is being studied. Also there are considered such procedures of air cargo processing as inspection and security. The detailed research proved the significance of inspection devices’ installation in the air cargo complex as the main factor in security maintenance.

This book is part of a series by Engineers Without Borders UK on technological solutions to the challenge of poverty alleviation. Basic transport infrastructure such as safe roads and bridges are largely taken for granted in the developed world yet silently play a major role in society. In combination with suitable vehicles, this infrastructure boosts mobility, allows access to essential services and, when designed well, enables healthy and sustainable travel for all. These benefits become clear in areas lacking basic transportation technologies. In many areas in low income countries moving fo...

The Journal of Transportation Engineering contains technical and professional articles on the planning, design, construction, maintenance, and operation of air, highway, rail, and urban transportation, as well as pipeline facilities for water, oil, and gas. Specific topics include airport and highway pavement maintenance and performance; management of roads, bridges, and transit systems; traffic management technology; construction and operation of pipelines; railway engineering; and economics and environmental aspects of transportation.

Infracture needs are growing and are dominated by transportation requirements. About 70 percent of the urgent needs are accounted for by highways and bridges. Civil engineers must take a concerted approach including education, technology, innovation, decision‐making, and research. Civil engineers should be leaders in formulating plans for innovation and research. New tools are becoming available to provide in‐depth analyses of total transportation systems. The projects must be planned and programmed for the entire life cycle, including construction operation and maintenance. Because of retirem...
