ことができる。In a traffic control office that manages a large number of route buses, it is necessary to know which buses are passing through which points for each route. In a bus operation management system called the bus location system, each bus and base station are connected via wireless lines, and the current location is displayed on the operation control panel at the operation control center based on the position information sent from the bus. do. With this system, the approach indicator at each stop can notify you of the approach of a bus.
