The application of scientific principles and technology to plan, operate, design and manage the facilities for any mode of transportation is referred to as transportation engineering. It aims to provide rapid, safe, efficient, comfortable, economical, convenient and environmentally compatible movement of goods and people. It uses the principles of engineering to improve the transportation system. Highway engineering and railroad engineering are the two major areas of transportation engineering. Highway engineering includes the estimation of the transportation needs of the public and the design, construction and operation of roads and highways as well as other vehicular facilities. Vehicular engineering is a sub-discipline of mechanical engineering which encompasses various fields such as marine engineering, aerospace engineering, rolling stock and automotive engineering. This book unfolds the innovative aspects of transportation and vehicular engineering which will be crucial for the holistic understanding of the subject. Some of the diverse topics covered in this book address the varied branches that fall under this category. It will provide comprehensive knowledge to the readers.
