Abstract

PURPOSE: A public traffic information collecting and guiding system is provided to achieve an effective time management during using a bus and to make a smooth traffic flow in a town area. CONSTITUTION: The number of a bus and what is the sequence of the bus from a starting point are transmitted to an infrared reception panel installed in each stop through a local area wireless transceiver(11) installed in the bus. The infrared reception panel sends the information collected like the above to a traffic information center through a wire/wireless network, and the traffic information center readjusts a service time and a service interval of the bus and informs it to each bus. And, the traffic information center transmits the above information to a panel of each stop in order for a user to use the information. And, the information is transmitted to a bus company and the company uses the information in managing the bus effectively.

Description

Collection and Display System of Public Transportation Information

The public transportation information system, in particular, the city bus information system exchanged information only by the existing wires, and enormous facility and operating costs were put in place, and the level of information was limited and simple. Simply, the user could only know the number of the bus where he wanted to go, but did not know the arrival time or delay time of the bus stop. In foreign countries, the Intelligent Transportation System (ITS) project is active, but in Korea, there is no visible system. A system for visually notifying the exact arrival and departure time of the bus, the representative means of public transportation, the traffic status of the bus route that the user intends to use at the user's current location, and the arrival time at the bus stop to be used It became. By providing this information, traffic jams can be reduced by driving the demands of self-driving drivers to the demands of public transportation. The transit guidance system, among other things, guides the movement of buses that are changing in real time, so it can be effectively used only by obtaining fast information and retransmitting this information. In order to implement such a service, traffic information collection, information transmission, central control in a traffic information center, and information retransmission to each stop are performed. These devices are also installed in the city, providing traffic and other useful information.

In order to collect traffic information, a local transceiver is attached to each city bus, and the number of buses and the number of buses from the starting point are transmitted to the receiving panel of the station. For example, infrared transmitters and receivers are inexpensive and convenient to use because they transmit air to the medium without using other infrastructure, like other facilities. Infrared laser systems are generally applied in point-to-point and line-of-sight situations, and the information between the bus and the station panels must be transmitted and received by each other. Operate with This information is displayed by the citizen who wants to use the bus to press the button of the bus he wants to ride, displaying the bus information, ie the GIS map of the neighboring area around the current user's stop, and the current location of the bus to be used on it. . Below the graphic is a text output of the current position of the bus that is currently arriving the fastest. In addition, the stop panel is configured in the form of a three-dimensional slope, and various information such as NEWS, stock news, advertisements, TV, weather, etc. are independently printed on each screen of the panel, and this information is used by the bus user to obtain bus information. Appears after a certain time has elapsed after pressing. The transmission and reception of such information is possible with a wireless network because the amount of data is not small, but it can be used by using various existing lines for effective operation.

Through the short range wireless transceiver 11 mounted on the bus, the number of the bus and the number of buses from the starting point are transmitted to the infrared receiving panels installed at each stop. The infrared receiver panel sends the collected information to the traffic information center through wired and wireless networks, and the traffic information center collects and analyzes the information and resets the bus's operating time or interval and notifies each bus. In addition, the information is re-transmitted to the panels of each stop so that the user can use the information. Information is then sent to the bus company, which is then used for efficient bus management. That is, a device for transmitting information (bus number, arrival time, departure order) of the bus to the panel of the station and receiving information transmitted from the traffic information center through the station panel. Accidents, breakdowns and special features can be entered directly by the driver.

In the case of the station transceiver 12, in particular, the infrared transceiver can be transmitted separately from each other because the two beams are transmitted across the same path as shown in Figure 3 but because the incident angle (RAA) is different. In other words, infrared signals transmitted from multiple buses can be separated and received by the panel of the station using these points. In each bus, data transmission only transmits bus information (number, dispatch number) to the panel of the station, and the panel retransmits the bus information reset by the traffic information center to each bus. The resetting of bus information in the traffic information center is to set the density of each bus line and the distance and temporal interval between the front and rear cars with the data received from each bus. The retransmission of the reconfigured information is periodically sent to the infrared rays of the stop panel, including the information of all the buses passing through the area, and each bus extracts only the information corresponding to itself and adjusts the interval and time of the bus. Operate.

The information panel 14 of the station transmits the information transmitted from the bus to the traffic information center through a wired / wireless network and outputs the information transmitted from the traffic information center to the panel. (A) Graphic screen-A device that displays the current location of the bus by displaying a graphic screen of the route of the bus to be used. (B) Text information-A device that displays the current location of the bus by outputting the text of the bus to be used as text information. This information is updated periodically to provide bus information in real time, and the stop panel on the road can be used for other useful purposes as a facility in the city. Device as a signboard for providing citizens with news, advertisements, weather and much more.

Traffic Information Center 13-As shown in FIG. 2, a bus in operation transmits bus information to information panels installed at each stop, and this information is transmitted to a traffic information center through a wired / wireless network. Traffic Information Center processes this information. Process and resend to the information panel of the bus stop. The bus user can know the current location of the bus and the bus route that he / she wants to use through graphic information or text information of a certain area through the information panel of the station. Receive and manage the current location information of all vehicles assigned each identifier and transmit it to the panel of each station. The company then manages bus routes with certain routes.

In order to solve the rapidly increasing traffic jams, the demand of self-driving drivers can be driven by the demand for public transportation. This can be solved by providing bus users with the convenience of using the buses that make up most of the current public transportation. To do it. In addition, the information center can use this information to smoothly manage the traffic flow in urban areas and provide a comfortable transportation environment for the city residents.
