and compile a master itinerary; the task required over 25 years and the resulting stone-engraved master itinerary was set up near the Pantheon. Travelers and itinerary sellers could make copies from it. Vehicles and transportation Outside the cities, Romans were avid riders and rode on or drove quite a number of vehicle types, some of which are mentioned here. Carts driven by oxen were used. Horse-drawn carts could travel up to per day, pedestrians . For purposes of description, Roman vehicles can be divided into the car, the coach, and the cart. Cars were used to transport one or two individuals, coaches were used to transport parties, and carts to transport cargo. Of the cars, the most popular was the carrus, a standard chariot form descending to the Romans from a greater antiquity. The top was open, the front closed. One survives in the Vatican. It carried a driver and a passenger. A carrus with two horses was a biga; three horses, a triga; and four horses a quadriga. The tyres were of iron.
