Cable cars, also known as rope ways or aerial tramways, don’t get much respect. These types of transportation systems, in which a cabin or other conveyance is suspended from a fixed cable and pulled by another cable, are often thought of as tourist-movers. But cable cars can have some practical applications in urban settings. They are especially useful where inclines are too steep for conventional mass transit and where they can serve as feeders to bus and metro systems. They have been successfully applied in growing cities of the developing world, where slums are often clustered on precipitous hills surrounding urban centers.
