ABSTRACT
This chapter presents various important aspects of transportation system failures and human error in transportation systems. Each year, a vast sum of money is spent around the globe to develop, manufacture, and operate transportation systems such as motor vehicles, aircraft, ships, and trains. A motor vehicle is composed of many parts and subsystems such as brakes, steering system, rim, engine, clutch, and transmission. The malfunctioning of parts and subsystems such as these can lead to motor vehicle failure. In railway systems, the construction of continuous welded rails (CWRs) is indispensable to reduce the vibration and the noise, improve the ride quality, and reduce the track maintenance cost. Over the years, many aviation accidents have occurred due to mechanical failures and mechanical-related pilot errors. More clearly, the mechanical-related pilot errors are the ones in which pilot errors were the actual cause but brought about by some kind of mechanical failures.
