Finding ways to cover long distances in as little time as possible is a longstanding challenge. As civilisations have evolved, so have many transport-related professions. People employed in this area include:
- carters and cab drivers, who drive vehicles pulled by animals;
- captains, helmspersons and pilots, who navigate ships;
- engine drivers and train operators, who drive railway trains or underground trains;
- drivers of motorised road vehicles;
- operators of trams, buses and trolleybuses in public transport systems;
- pilots of aircraft and helicopters; and
- cyclists, rickshaw pullers and drivers of vehicles propelled by muscle power.
Vehicles that use different types of fuel (solid and liquid fuels, electricity, nuclear fuel etc.) have a significant environmental impact. Today, drivers of motorised road vehicles have the biggest impact on the state of the environment and human health. The extent of this impact depends on the type of vehicle, its level of maintenance, and the owner's driving style.
