In a first course in transportation engineering at the undergraduate level, the various aspects of road transportation, particularly highway engineering, are generally covered in detail. This book extends the discussion to other critical components of the transportation system, namely railways, airways and waterways, by emphasizing the basic infrastructural components, principles of planning, functional design, operation and management of the infrastructure in each case. It dwells on the latest approaches/methodologies in the design and evaluation of railways, airports and docks & harbours, and includes a large number of illustrations, images and worked-out examples to enhance the understanding of the design elements and components of the system in a practical way.
Salient features of the book
It provides a comprehensive, yet concise coverage of the following areas, making it ideal for a one semester course in transportation engineering pertaining to railways, airport and harbours. Railways: Details of Indian Railway routes; features of permanent way components; geometric design of railway tracks; functional aspects of points and crossings with solved examples on design of turnout components; signals used in Indian Railways, their aspect form; working principle of axle counter and track circuit; particulars of automatic signalling system; types of interlocking systems and their merits and demerits
Airports: Airport master plan and runway orientation; aircraft characteristics, design and orientation of runways using Wind Rose diagrams; FAA design standard for minimum wind coverage; classification of airports and estimation of design runway length (FAA and ICAO standards); standards for geometric components of runway and taxiway system as per FAA, ICAI and CASA; description of instrument landing system (ILS), approach lighting system, VASI, precision approach path indicator lighting system and visual aids; air traffic control (ATC) with the terminal component facilities; design of runway pavements based on UFC, FAA, PCA, US Army and Air Force systems; ACN-PCN system of rating aerodrome pavements; airport pavement drainage system, failures-evaluation and the maintenance aspects
Docks & Harbours: Planning, layout, construction and maintenance of docks and harbours
