Background of the Invention

When driving or walking on a road, we encounter various traffic situations, such as roads under construction, landslides, traffic control, traffic jams, and bridge control. In this case, people must make a detour.

In order to avoid passing through a specific traffic situation, people may call service to listen to a radio station's traffic or receive a voice traffic report. However, in order to meet the needs of the public, regular radio station traffic information or telephone voice traffic status reports provide traffic information for a wide range of geometric areas. Such a traffic condition broadcasting or telephone voice traffic condition reporting service cannot provide traffic situation information about an individual's geometric location to satisfy individual needs. In addition, since the telephone voice traffic report service is updated every predetermined time elapses, the user cannot obtain real-time traffic status information.

Therefore, there is a need to provide a real-time traffic situation reporting system that eliminates the above problems.

Detailed description of the invention

1 is a system block diagram of one embodiment according to the present invention. According to this embodiment, the traffic reporting system is provided to a vehicle. Instead, the traffic reporting system may be provided in various personal portable electronic devices, for example, PDA (Personal Digital Assistant), mobile phone, and the like, and real-time traffic information for an individual who corresponds to the current geometric region where the user is currently located. It can also be provided.

As shown in FIG. 1, the traffic situation reporting system includes a position measuring unit 1, a radio wave transmitting / receiving unit 2, an output unit 3, a microprocessor 4, a memory device 5, and It consists of an electronic map database and is mounted on the vehicle.

The position measuring unit 1 according to the present embodiment receives a signal from a plurality of satellites 9 in outer space, and calculates the current longitude and latitude coordinates (Xc, Yc) of the vehicle (Global Positioning System) to be.

FIG. 2 shows the contents of the traffic situation previously collected by the remote traffic situation control center 8, where "HW01S" is "first highway heading south", "TPE C6" is "Taipei City". C means sixth intersection "," J "means" traffic jam "and" C "means" traffic control ". The traffic situation control center 8 broadcasts a traffic situation via a radio. According to this embodiment, the radio transmitting / receiving unit 2 is a pager for receiving a broadcast from the traffic condition control center 8.

Referring to FIG. 3, in order to shorten the length of outgoing data to shorten the outgoing or receiving time, the traffic situation control center 8 provides a geometric area code for each traffic situation and a traffic situation code for the relevant traffic situation. Broadcasts. The code for the geometric area and the code for the traffic situation are received by the radio transmitting / receiving unit (pager 2) and then stored in the memory device 5 for the microprocessor 4 to read. The memory device 5 stores accurate longitude and latitude coordinates (Xi, Yi) and / or descriptions of all traffic conditions codes of all geometric regions.

The microprocessor 4 sets a predetermined condition therein, for example, "the first highway HW01 + a radius of 30 km". Thus, when the longitude and latitude coordinates (Xc, Yc) of the geometric area code of the vehicle are obtained from the position measuring unit 1, the microprocessor 4 has the geometricality of all traffic conditions stored in the memory device 5. Compare the longitude and latitude coordinates (Xi, Yi) of the area code, and then select the latitude and longitude coordinates (Xi, Yi) of the geometric region of the traffic situation suitable for the predetermined conditions and relevant traffic information (see See FIG. 4).

The microprocessor 4 then controls the output unit 3 to output the selected traffic situation information. The output unit 3 may be an LCD, an OSD (On Screen Display), a head-up display (Head-up display), etc. for displaying traffic situation information by text. Instead, the selected traffic situation information shown in FIG. 4 may be graphically displayed as shown in FIG. 5, and the indication “X” between the 30 km position and the 35 km position means a traffic jam position. In addition, the voice synthesizer may convert traffic information into voice for output. Preferably, the microprocessor 4 preferentially retrieves and broadcasts traffic state information of the nearest position in the same forward direction.

In combination with an electronic map database, the microprocessor may read the electronic map from the electronic map database 60 to indicate the location of the selected traffic situation on the screen. For example, FIG. 6 shows the traffic shown in FIG. Displays an electronic map of Taipei City obtained from an electronic map database 6 that meets a predetermined condition of "Taipei City + Radius 5km Area" corresponding to context information (stored in the memory device 5), "X" means traffic jam and "C" means traffic control area.

The traffic reporting system is provided by the position measuring unit 1 to further compare traffic conditions for different geometric areas broadcast from the traffic condition control center 8 and to output the selected traffic conditions in a timely manner. Since the present longitude and latitude coordinates (Xc, Yc) of the vehicle meeting the dynamic information are calculated, the present invention provides all vehicle drivers with real-time traffic situation information that meets individual needs.

Referring again to FIG. 1, the traffic situation reporting system further comprises an input unit 7 for inputting or changing the preset condition. The input unit 7 may be a function key, a keyboard, or a radio receiver.

The position measuring unit 1 is not necessarily limited to GPS. Instead, the positioning unit 1 is a wireless communication network, for example a GPS (Global Positioning System) network configured to transmit the longitude and latitude coordinates of the three nearest base stations of the message to determine the geometric position of the current vehicle. Or a Global System for Mobile (GSM) network.

RDS (Radio Digital Broadcasting) or GPRS (General Packet Radio Service) radio broadcasting may replace the radio broadcasting of the traffic control center 8. If the network has sufficient bandwidth or provides a sufficient transmission speed, the traffic situation content broadcast by the traffic situation control center 8 can be directly transmitted in sufficient detail. If the computational speed of the microprocessor 4 is sufficient to directly compare, the memory device 5 may be eliminated.

In addition, the traffic situation control center 8 can reduce the length of the transmission data by arranging and summarizing all traffic conditions in advance. For example, among the six consecutive traffic jam locations shown in FIG. 4, only the first and last traffic location (30 km location and 35 km location) and the relevant traffic status code need to be transmitted, and the transmission data is "$ HW01S 030 035 J // ".

The present invention has the effect of providing a real-time traffic situation reporting system that satisfies the needs of individual users by dynamically providing real-time traffic situation information corresponding to the current location of the user.

Simple modifications or changes of the present invention can be easily carried out by those skilled in the art, and all such modifications or changes can be seen to be included in the scope of the present invention.
