Description

System and method for guiding traffic time of public transportation vehicles using communications terminal}

The present invention relates to a traffic time guidance system and method for guiding a traffic time by a communication network using global positioning system (GPS) information, and more particularly, to operate according to a predetermined timetable and a route through a mobile phone. The present invention relates to a system and a method for guiding a transit time of public transportation such as city buses, intercity buses, village buses, urban railways, trains, railways, ships, and airplanes.

As shown in FIG. 1, the conventional vehicle driving guide information includes location information P1-P3 of the stop AC, vehicle door opening and closing information d1-d2, and section information D1-D2 of the stop. The station arrival information of the vehicle is broadcasted by data stored in advance by the vehicle operation information such as the route information and the vehicle speed information (V1-V2). That is, when a vehicle such as a city or an intercity bus 10 arrives at a stop A, the stop location information P1 is transmitted to the vehicle by a sensor that can identify the stop location installed on the vehicle and the stop. Received vehicle knows the information about the next destination stop (B), and can broadcast the announcement of the arrival time of the next destination stop. The stop position information and arrival time information are measured and output by data such as a gyro sensor, a digital speed meter, and a pre-input distance. Of course, the stop position information is measured by the sensor in FIG. 1, but is actually used to output the guide broadcast stored by the driver 20. Therefore, it is difficult to provide accurate vehicle operation information to passengers because there is a possibility of a large number of measurement errors or operation errors, whether sensing the stop position and the speed of the vehicle or using the average data input. In addition, the vehicle operation information guidance system of FIG. 1 provides vehicle operation information only to crew members and passengers in the vehicle, and to those who do not ride the vehicle, when the desired vehicle arrives at the desired stop, or which vehicle to the desired destination. I couldn't figure out which route to use.

Recently, various application examples have been developed or used, such as navigation (navigation) service and geographic information system for land, sea, and air operations using the received location information through satellites. In the case of using GPS, the customer can identify the position of a moving object such as a vehicle, a ship or an airplane together with the place name. That is, since the data packet in GPS basically has measurement time, location coordinate value and number of subscriber terminal, it is possible to grasp the location of mobile chain mobile communication terminal by time zone, and if necessary, it can map the movement trace to GIS (geographic information system). It can also be displayed on the screen. In the case of the location tracking method using the GPS information, the GPS location information using the satellite can be used to determine the location of the moving object within an error range of 100 m. Provides a variety of reliable traffic and geographic information. However, even in this case, it is pointed out that the information user has to carry or carry the terminal in the vehicle, and such information is not available or very difficult to use from outside the vehicle.

In addition, Korean Patent Publication No. 98-034092 (traffic situation guidance device using wireless mobile communication terminal), No. 98-049743 (vehicle navigation device using mobile communication device and GPS receiver), 99-25223 (Traffic Information Providing System), No. 99-029052 (Traffic Information Information Terminal Device Using Wireless Communication Network), No. 99-041760 (Road Traffic Information Information System), and No. 00-010927 (Mobile Phone Wireless) The technology for providing traffic information using GPS and communication technology, such as real-time traffic information providing technology using communication, has been filed and disclosed.However, the arrival time and destination of public transportation means traveling along certain timetables and routes are still disclosed.

In particular, the transportation time such as the arrival time of the vehicle and the time required for the destination is the location of the wireless mobile terminal of unspecified information users. There was no service technology that was provided regardless.

Accordingly, an object of the present invention is to receive GPS information from a satellite in a public transportation means that operates according to a certain route and timetable such as a bus, a train, a ship, an aircraft, and transmits and stores the GPS information in real time to a host server through a communication network. When the information user who does not board the vehicle requests the traffic time such as the arrival time and the required time through the communication network, the time required for the arrival time and the destination of the requested vehicle is based on the traffic information such as the traffic flow status according to the pre-stored route. It is to provide a traffic time guidance system and method for calculating and providing the same traffic time.

Another object of the present invention is in addition to the traffic time, such as the arrival time and the required time of the means of transportation, the traffic according to the pre-stored route when requesting the traffic additional information such as the best transfer information, route optimal route information, route linkage affiliate location information It is to provide a traffic time guidance system and method that calculates and provides the requested traffic time and additional traffic information based on traffic information such as flow status.

Still another object of the present invention is a traffic time guidance system for providing an optimal route guidance and the arrival time of a vehicle stop and the time required for transportation when the traveler inputs his location information and final destination information according to the location information of the stop and To provide a way.

Since the procedure for accepting information from outside is obvious to a person skilled in the art, a detailed description thereof will be omitted, but it is desirable to provide an online service in addition to providing an online service at the same time as a general information use service so as not to inconvenience customers.

In the present invention, the position of the vehicle is determined using the GPS information, and the arrival time of the moving vehicle and the estimated time to the destination are provided using the GPS vehicle position information. Since the GPS location information is provided in minute time units and in almost real time units, the traffic time guide host server using the location information can predict and provide a more accurate time of arrival of the vehicle and the time required to the destination. Therefore, in the present invention, the location information is collected from a vehicle equipped with a GPS receiver using a communication network, and thus, the arrival time of the moving vehicle and the time required to the destination can be provided very accurately by utilizing the traffic flow information according to the stored route. have.

Thus, traffic related information such as bus arrival time, estimated time required to travel to the destination, and other transit information of a vehicle that wants traffic information services such as route guidance and time required, which were conventionally limited to passengers in a vehicle or waiting at a stop. It can be provided to customers regardless of the place through the personal wireless handheld terminal possessed by the user with accurate time information. Through such vehicle guide information, buses and cities such as city buses, intercity buses, express buses, and town buses The use of public transportation such as railways, subways, trains, such as ships, aircrafts, in particular the use of moving vehicles according to a certain route and timetable will be more convenient and easier.
