Walking bus

A walking bus (walking school bus) is a form of student transport for young schoolchildren who, chaperoned typically by two adults (a "driver" leads and a "conductor" follows), walk. The crocodile may walk to school along a set route, with some similarities to a school bus route, with designated "bus stops" and "pick up times" at which they pick up and "drop off" children. In Britain a group of schoolchildren walking together in a long line of pairs on an activity without stops or pickups, escorted by teachers, has been referred to as a crocodile since at least 1870.
