Description

Bus service information guidance device {APPARATUS FOR PROVIDING INFORMATION OF BUS SERVICE}

The present invention relates to a bus operation information guide device, and in particular, so that various information (for example, route information, estimated time of bus arrival, image information inside the bus, etc.) of the currently operating bus can be grasped by the bus control center in real time. It relates to a bus service information guide device.

The most common means of public transportation are buses, taxis and subways. Since taxis do not have specific destinations, taxis can be used without restrictions if desired by the user.In the case of subways, the intervals between dispatches are short, and the arrival time and the last train time are provided to the user while managing the operation status by using their own communication network. Information is provided so that the user does not feel much inconvenience in using it.

However, in the case of buses, there is a problem that the allocation interval is generally longer than that of the subway, and the bus allocation interval may be delayed even more when traffic congestion occurs.

In addition, in the case of a conventional bus transportation system, a user waiting for a bus to be boarded at a stop does not know when a desired bus will arrive at the stop, and there is an inconvenience of waiting vaguely until a desired bus arrives.

In addition, a bus route guide may be installed near a bus stop for the convenience of a user who wants to use a conventional bus transportation system, but information that can be provided through such a bus route guide is limited to simple route information. There was a problem that did not satisfy the request.

In addition, the conventional bus transportation system is unable to monitor the real-time situation in the bus in the bus control center, there is a problem that can not perform urgent processing in the event of an accident or emergency in the bus.

Accordingly, an object of the present invention is to provide a bus driving information guide device that can provide a variety of information related to the operation of the city bus in real time through the information board, terminal, Internet, etc. will be.

Another object of the present invention is to allow the bus company to monitor and manage the operation of the city bus in real time and to check the status of the bus in real time, thereby improving the service to the city bus users and consequently reducing the traffic of passenger cars, thereby reducing urban traffic problems. It is to provide a bus operation information guide device that can alleviate the risk and improve the profitability of bus companies through efficient dispatch management.

Another object of the present invention is not only to share the operating status information of the city bus between the bus company and the driver, but also to allow the driver and the driver to share the driving status information by transmitting and receiving voice data and text data. It is to provide an information guide device.

Another object of the present invention is to provide a bus operation information guide device that can utilize the real-time information related to the city bus operation as a material for public transportation policy.
