Abstract:
1. A public transportation control system, comprising: an on-board terminal equipped to each public bus traveling on a road to transmit bus information of an associated bus and to display transportation information for adjusting a traveling distance between the buses after receiving the transportation information created based on the bus information from outside through wireless communication; a plurality of transportation information guidance centers installed to bus stops to transmit the bus information to the outside after collecting the bus information transmitted from the on-board terminals of the buses, and to transmit transportation information of the associated bus to the on-board terminal of the associated bus while supplying transportation guidance information of the associated bus to passengers waiting at the bus stops after receiving the transportation information and the transportation guidance information created on the basis of the bus information from the outside through the wireless communication; a transportation management server to store the bus information after receiving the bus information transmitted from the on-board terminals through the transportation information guidance centers via a dedicated communication network, and to transmit the transportation information and the transportation guidance information to the transportation information guidance centers installed to the bus stops after creating the transportation information for adjustment of the distance between the buses and the transportation guidance information for guidance of arrival schedules of the buses; and at least one transportation information collecting device installed at a certain position on the road, where the public buses travel, to transmit the bus information to the transportation management server after collecting the bus information transmitted from the on-board terminals, and to transmit the transportation information of the associated bus to the on-board terminal of the associated bus after receiving the transportation information created on the basis of the transmitted bus information from the transportation management server; wherein the bus information collected by the on-board terminal and stored in the transportation management server comprises basic information as to a bus number and a line number of the associated bus, road condition information as to construction and accident blocks, and bus condition information as to whether the associated bus is a last bus, a defective bus or an accident bus.
