Complete History of Wheeled Transportation 

While the wheel itself has changed little over time, it has immeasurably altered the nature of transportation. This insightful volume examines the various wheeled conveyances that have been instrumental in agriculture and commerce-carts and wagons, for instance-as well as those that have facilitated human travel-coaches, bicycles, cars, and buses, among others. Also explored is the evolution of roads, as they have expanded to accommodate various modes of wheeled transportation.
