Inefficient ports can stall a country's trade growth and also increase the costs of transportation. Rising inefficiencies in ports have therefore forced the governments all over the world to deregulate the port system. The port sector in several developing countries has been undergoing revolutionary transformation from a subsistence infrastructure resource into a more capital intensive, commercially oriented facility during the last two decades. In India, awareness towards the impact of port infrastructure on economic development in general and international trade in particular has increased in recent years partly as a result of rising trade transportation costs. One of the objectives of this book is therefore to understand the role the port plays in India's economic development. The book tries to quantitatively evaluate the structural metamorphosis in Indian port sector. The main emphasis of the book is on performance evaluation, technological change, total factor productivity growth, market concentration, and competitiveness of Indian ports for the last two and a half decades. This book deals with these vital issues and questions through a detailed analytical framework. Above all, one protracted objective of this book is to create a ground for discussion on various aspects of port development and the resultant policy action.

This book proposes the tool change methods for the excessive tool wear in the construction rules of shield tunnel construction in China. From the perspective of shield tunneling, atmospheric pressure tool change, pressure opening and tool change, and other special techniques, the tool change technologies are proposed. It highlights a number of tool-changing techniques and research and development work, including pressure-changing tools, tool-changing tools in the tool-cylinder arm, and cutter-tooth cutter inter-change since the beginning of the construction of the Nanjing Yangtze River Tunnel.

This book discusses the multiple systems that make commercial jet travel safe and convenient. The author starts by tracing the evolution of commercial jets from the Boeing 707 to the double decker Airbus A380. The next 7 chapters discuss flight controls, along with the high lift surfaces (flaps and slats) that are essential to allow high speed, low drag aircraft to take-off and land. The other systems include Engines/Nacelles, Cabin Pressurization and Air Conditioning systems, Landing Gear and brakes, Fuel Systems, Instruments/Sensors, and finally Deicing systems for the wings, nacelles and external air speed sensors. Case studies describe a significant accident that arose from a failure in the various systems described. The final chapter summarizes the past 60 years of jet travel and describe how these systems have created a cheaper, safer mode of travel than any other.

Pavements are the most ubiquitous of all man-made structures, and they have an enormous impact on environmental quality. They are responsible for hydrocarbon pollutants, excess runoff, groundwater decline and the resulting local water shortages, temperature increases in the urban "heat island," and for the ability of trees to extend their roots in order to live. Porous pavements, despite their ability to mitigate these factors, remain the object of much skepticism and controversy. Written by a renowned expert with 25 years of experience in urban watershed management, Porous Pavements is the first comprehensive "encyclopedia" of porous pavement materials. The book begins with five chapters that lay a foundation for all porous pavement materials and applications, introducing the types of materials and arrangements, their roles in the urban environment, and the principles of pavement structure, hydrology, and rooting space. The following nine chapters outline the costs, maintenance requirements, advantages and disadvantages for different applications, installation methods, sources of standard specifications, and performance levels for each family of porous pavement materials. Relying on case studies and factual data from observed experience, and containing abundant references for further information, Porous Pavements gives responsible practitioners a complete toolbox from which to select the appropriate material for site-specific conditions, providing a "green" alternative to impervious pavements.

Nearly all highway, airport, dock and industrial pavements contain large quantities of untreated aggregate in the form of unbound pavement layers. In many pavements, which are lightly or moderately trafficked, crushed rock or gravel derived aggregates comprise the majority of the construction or, in the case of unsealed pavements, all of the structure. This book provides studies of the performance and description of this material that will help the reader to better understand its characteristics and behaviour both alone and as part of the pavement structure it forms. This work will be useful to practitioners, policy makers, researchers and students. It forms a sequel to the earlier book "Unbound Aggregates in Road Construction" also published by Balkema

Developing countries in the tropics often have challenging natural conditions and different institutional and financial institutions to industrialized countries. However, most textbooks on road engineering are based on experience in industrialized countries with temperate climates.

Road traffic and its impacts affect all aspects of modern life, leisure and industry, with safety, congestion and pollution being of greatest public concern. Transport planning increasingly emphasises travel demand management (TDM) and traffic calming - aided by dynamic, lower cost data from Intelligent Transport Systems (ITS) - to enable real time monitoring, control and traveller information. This second edition of a highly successful work has been fully updated since its first publication in 1996 to reflect developments in technology available to the traffic analyst and in the social, ecological and economic environment. New sections are included on shockwaves, data capture without surveys, traffic incidents, delay estimation, off-line use of on-line data, environmental sensitivity, and controlled crash tests. The authors introduce and demonstrate techniques with which the analyst, engineer or planner can examine traffic problems. The underlying theme is that proper understanding of traffic systems performance and traffic problems can only come from the intelligent processing, refinement, appraisal and evaluation of traffic data. Arranged in five parts, the book offers an integrated approach to tackling road traffic problems: c How to gain information and understanding about traffic c The theories of traffic flow c The principles of good survey planning and management c Specific types of traffic studies c Analytical techniques for transforming raw data into useful information. Understanding Traffic Systems provides cogent insights into the techniques of traffic data collection and analysis, the application of traffic theory and the role of data in analysis and decision making. Its breadth and use of examples from several countries make it a useful reference text for students and researchers, as well as an essential tool for practising traffic engineers and planners.

This book covers the basic scientific theory and related application technologies of the pantograph-catenary system, including research findings on pantograph/catenary contact resistance, pantograph interface thermal effect, laws and characteristics of current-carrying friction and wear, the main research methods for pantograph arcs, the effects of arcs on pantograph systems and onboard equipment, and the materials used for pantographs and contact wires. Given its scope, it offers a valuable resource for students, scholars, and development engineers alike. The relationship between pantograph and catenary is one of the three core aspects of the safe operation of high-speed electrified railways. The pantograph system provides electric power for the high-speed train through the sliding electric contact. As the train's operating speed increases, the pantograph system enters a state of prolonged sliding/vibration, resulting in frequent arcs, electrode erosion, and increased wear.

The aim of the studies presented in this report is the implementation of rational concepts and testing procedures for the design and manufacture of bituminous materials for applications in pavement construction. Practical test procedures are recommended for binder evaluation, mix design and performance assessment of bituminous materials. The three main topics addressed are binder testing, mix design and mechanical testing of mixtures. Each is examined through inter-laboratory tests and there is a literary review of existing practices and methods for the production of polymer-modified binders, mixture design and the mechanical properties of mixtures.

Incorporating the proceedings of RILEM TC-PRC third conference on this subject, this volume includes papers from road authorities, engineers, researchers, contractors and manufacturers discussing the implementation and the long term behaviour of overlay systems. This book should be of interest to research institutes concerned with transportation and highway engineering; government and local authority engineers, contractors, material suppliers.

At first glance, roads seem like the simplest possible geotechnical structures. However, analysis of these structures runs up against complexities related to the intense stresses experienced by road surfaces, their intense interaction with climate, and the complicated behavior of the materials used in road construction. Modern mechanistic approaches to road design provide the tools capable of developing new technical solutions. However, use of these approaches requires deep understanding of the behavior of constituent materials and their interaction with water and heat which has recently been acquired thanks to advances in geotechnical engineering. The author comprehensively describes and explains these advances and their use in road engineering in the two-volume set Geotechnics of Roads, compiling information that had hitherto only been available in numerous research papers. Geotechnics of Roads: Fundamentals presents stresses and strains in road structures, water and heat migration within and between layers of road materials, and the effects of water on the strength and stiffness of those materials. It includes a deep analysis of soil compaction, one of the most important issues in road construction. Compaction accounts for only a small proportion of a construction budget but its effects on the long-term performance of a road are decisive. In addition, the book describes methodologies for nondestructive road evaluation including analysis of continuous compaction control, a powerful technique for real-time quality control of road structures. This unique book will be of value to civil, structural and geotechnical engineers worldwide.

This book describes an effective decision-making and planning architecture for enhancing the navigation capabilities of automated vehicles in the presence of non-detailed, open-source maps. The system involves dynamically obtaining road corridors from map information and utilizing a camera-based lane detection system to update and enhance the navigable space in order to address the issues of intrinsic uncertainty and low-fidelity. An efficient and human-like local planner then determines, within a probabilistic framework, a safe motion trajectory, ensuring the continuity of the path curvature and limiting longitudinal and lateral accelerations. LiDAR-based perception is then used to identify the driving scenario, and subsequently re-plan the trajectory, leading in some cases to adjustment of the high-level route to reach the given destination. The method has been validated through extensive theoretical and experimental analyses, which are reported here in detail.

This book presents a rigorous treatment of the fundamental mathematical behaviour of pavement structures under dynamic loading. The subject is of importance in design of economic highway pavements and aircraft runways for increasingly arduous performance requirements. The author and his team have worked for many years on developing dynamic testing methods of road surfaces and materials using vibration techniques with low excitation energy. Their experimental work on test tracks has led to the development and refinement of models of the behaviour of pavement structures, which can be used for practical applications. The book contains many numerical examples of pavement evaluation and design using this approach. The book should be valuable for researchers and graduate students in the field of highway engineering, structural dynamics and soil mechanics, and also for professional highway engineers concerned with dynamic behaviour of pavements.

As a consequence of so much construction work being carried out on or near highways, contractors ignore at their peril the law of highways and the influence it has, or should have, on their working methods and practices. Some knowledge of the law relating to highways is essential to anyone involved in the construction process, including the architect, engineer or surveyor advising a client as to what is possible and the contractor actually carrying out the contract works. By avoiding legal language, this book aims to provide practical guidance from maintenance and improvements to activities related to construction work on or near highways.
