Transportation engineering applies scientific principles and technology to plan, operate, design, and manage transportation facilities for all modes of transport. Its goal is to ensure rapid, safe, efficient, comfortable, economical, convenient, and environmentally-friendly movement of goods and people. This field utilizes engineering principles to enhance transportation systems, focusing on two major areas: highway engineering and railroad engineering. Highway engineering involves assessing public transportation needs and designing, constructing, and managing roads, highways, and related facilities. Vehicular engineering, a sub-discipline of mechanical engineering, spans marine, aerospace, rolling stock, and automotive engineering. This book explores innovative aspects of transportation and vehicular engineering, providing comprehensive insights into diverse branches of the field.
