Description

{Bus Operation Guiding System}

More particularly, the present invention relates to a system and method for generating 3D route information by synthesizing information collected through sensors and cameras provided in a bus vehicle, GPS information, and information transmitted from an ECU / DTG of a bus vehicle And to guide the driver to the bus operation guidance system.

In general, buses are used as one of the most popular means of transportation, regardless of terrain, area, or time. As such, buses are the most popular means of transportation, but given the environmental aspects, they can be the largest contributor to the environment, as compared to other forms of public transportation, such as trains, airplanes, and boats.

In recent years, although the penetration rate of automobiles has greatly increased due to the improvement of the overall income level, the dependency of public transportation, especially buses, trains and railways, is still high.

On the other hand, public transportation companies that provide such public transportation services continue to strive to provide improved service by systematically managing bus routes and providing high-utilization route information to bus drivers.

In the prior art, only the information on the distance and the time interval between the preceding bus and the following bus is provided to the bus recorder provided in the bus at the main point (usually the bus stop) of the route, . In addition, conventionally, since operating information such as altitude, rapid curve section, and irregularity section on a service route relied entirely on the experience of the driver, it became necessary to systematically manage various information of the service route.
