The growth of Czechoslovak cities in size and numbers after World War II, accompanied by an increase of car ownership in the 60s, caused a rapid deterioration of traffic conditions in the cities. Training of new transportation engineers at the technical universities, constitution of transportation engineering organisations in large and medium-sized cities and an effective state support for the organisation and management measures adopted by these agencies helped to relieve the situation. A survey is given of tasks devolving upon transportation engineering organisations. The transportation poli...

This chapter describes how the bicycle is a flexible mode of transportation that can be used for a variety of trips within the intermodal transportation system and by a wide range of people. Creative designs have been required in many cases to retrofit our auto-dominated road system to promote and encourage bicycling. However, over the last decade strong progress has been made throughout the United States in order to reintroduce well-engineered bicycle transportation facilities into cities, towns, and rural areas. A wide range of guidance is available for designers who may not be cyclists or b...

This chapter reviews recent research and practice in three areas related to transportation and hazards: environmental hazards to transportation systems, transportation risks to proximal people and resources, and the role of transportation in emergency management.

This chapter describes how previous research conducted by Pouliot (2002) indicates that transportation represents one of the most important human activities worldwide. Furthermore, he maintains that transportation is a multidimensional service that affects many aspects of daily life. While transportation is complex and multifaceted, it could be viewed as simply the movement between two or more points. According to Wood and Johnson (1996), transportation is the physical movement of people and goods between points. Therefore, transportation is a very broad, generic term and it consists of three ...

This chapter describes how transportation economics is a very broad field. It includes the application of economic principles to pricing, cost analyses, and regulatory issues. It also includes the analysis of transportation impacts on land use, economic development, and the environment. The field of transportation economics also includes the analysis of costs and benefits of transportation improvement and initial construction projects. It is this later aspect of transportation economics that is of interest to transportation engineers and is the subject described in this chapter. The chapter be...

This chapter describes how diesel-electric locomotives and electric locomotives are classified by wheel arrangement with letters representing the number of axles in a rigid truck (A for one axle, B for two axles, C for three axles, etc.). Idler axles between drivers may be numerals. A plus sign indicates articulated trucks or motive power units. A minus sign indicates separate nonarticulated trucks. This nomenclature is explained in RP-5523, issued by the Association of American Railroads (AAR). Virtually all modern locomotives are of either B-B or C-C configuration. The high efficiency of the...

A model was produced that describes the adaptive network development displayed by the slime mold and might provide insight into how to implement properties like resistance of transport systems to local failures into similar human-designed systems.

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.

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.

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...

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...

Concerns about the negative economic, environmental and social impacts of traffic growth are leading to the need to re-think from first principles the way in which we meet transport needs in the future. The 'predict and provide' response to traffic growth is not sustainable, but alternatives are possible and have been successfully adopted in a number of places.

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.

There can be few people in this country who have not been impressed by the complexity of instruments and controls in the cockpit of a modern transport aircraft — if not the real thing, at least they will have seen pictures.

This chapter describes how noise is a serious issue that should be considered in all stages of transportation system projects, from original design and construction to modifications. Transportation-related noise affects millions of people and, in many cases, requires local, state, and federal governments to provide noise abutment to help improve or restore their quality of life. The impact of noise on the quality of life can be substantial, especially with expanding transportation systems. This is why there is an increasing need for noise control, and why the field of transportation-related no...

This chapter describes the role of the marine transportation systems (MTS) within a context of more familiar transportation modes like automobile, trucking and rail. Using this context, the role and complexity of the MTS can be better understood. The waterway network may not have rail track or asphalt defining its limits and extent, but navigable waterways are more like highways than an uncharted horizon. Specific features unique to the MTS will be summarized, including fleet characteristics for vessels engaged in cargo transportation, fishing, or other services. Like any broad system of diffe...

More than at any other time during the past decade, it has been observed that there is a clear shift in transportation policies away from construction of new facilities towards a more efficient management of existing transportation systems in order to meet the ever-increasing transportation demand. Contrary to widespread belief, this change in direction has not eliminated projects for new highway and projects for major maintenance and reconstruction of existing highways. Every year billions of U.S. dollars are allocated to new transportation facilities. This chapter describes how there is a ge...

This chapter describes how planning for freight is a complex and difficult task. Because of the differences between public and private sector operations and planning and the variability of commodities and the means for shipping commodities, the ability of a public planning agency to grasp the breadth of this activity is problematic at best. However, if transportation planners are to make more effective decisions in the current political and economic environment, a method for incorporating freight into the planning process is critical. This chapter has attempted to provide a backbone on which t...

Imagine the future is now - people and goods are moving around quietly and efficiently. To have designed such an environment, we would have had to break free from all that appeared logical and proven in the past, and challenge the boundaries of creative thinking with visionary new concepts. The transport industry is often conservative, but it is increasingly being swamped by rampant urbanisation and pollution constraints. Will our foresight be capable of designing beyond the past and present trends? While the specifics may be difficult to forecast, a number of macro-drivers will reshape the tr...
