Referring to FIG. 1, the route providing system includes a GPS 10, a plurality of vehicles 11-1 to 11 -N providing their location information, a traffic information providing system 13, and a vehicle requesting route information ( 12).

The GPS 11 is a system for measuring the position of all moving objects on the earth by calculating distance and distance fluctuation speed. The plurality of vehicles 11-1 to 11-N providing their location information are equipped with navigation and measure their current location based on the GPS data received from the GPS 10. Hereinafter, navigation mounted on a vehicle that provides its own location information will be referred to as a location information providing terminal. In general, the location information providing terminal 11 receives GPS data from at least three GPS, and measures its location using the received GPS data. The location information providing terminal 11 notifies the traffic information providing system 13 of its location information at regular time intervals. In addition, the location information providing terminal 11 notifies the traffic information providing system 13 of the cause of the congestion when its speed is less than or equal to the set speed, that is, when congestion occurs. The structure of the location information providing terminal 11 will be described later with reference to FIG. 2.

The location information providing terminal 11 includes a GPS receiver 21, a control unit (navigation module) 20, an input unit 22, a display unit 23, a storage unit 24, and a traffic information receiver 25. The GPS receiver 21 receives a GPS satellite signal provided from the GPS 10, and the controller 20 reads the GPS satellite signal received from the GPS receiver 21 to shorten a path to a current location and a destination of the vehicle. To calculate. In addition, the controller 20 notifies the traffic information providing system 13 of its current location information on a first set time basis. In addition, the controller 20 measures the average speed of the vehicle in units of a second set time, and recognizes that the vehicle congestion has occurred in the current section when the measured average speed is less than or equal to a preset threshold speed. The threshold speed may be differently set in a time zone and a driving section in which the vehicle is currently driving. When the controller 20 recognizes that the current congestion has occurred, the controller 20 controls the display unit 23 to display a plurality of stored causes of congestion, and transmits the congestion cause and location information input from the input unit 22 to the traffic information providing system 13. To be informed.

The input unit 22 receives information for using navigation. That is, the input unit 22 receives detailed route and detour route information from a user in a destination and a specific section. In addition, the input unit 22 receives one of the causes of congestion displayed on the display unit 23.

The display unit 23 displays the driving guide information calculated by the control unit 20 and the plurality of causes of congestion.

The storage unit 24 stores map information, a threshold speed, and a plurality of congestion causes for navigation use.

Table 1 shows an example of the threshold speed stored in the storage unit 24.

TABLE 1

According to Table 1, the threshold speed stored in the storage unit 24 is set differently according to the section and the time zone currently running. In general, the critical speed of the highway is set higher than the critical speed of downtown, and the critical speed of the late-night time zone is set higher than the critical speed of the rush hour. The threshold speed may be set using the maximum speed of the currently driving section.

The storage unit 24 also stores a plurality of causes of congestion. Accidents, traffic increases and traffic control can be the cause of congestion.

3 is a flowchart illustrating an operation performed in a location information providing terminal according to an embodiment of the present invention. Hereinafter, an operation performed in the location information providing terminal according to an embodiment of the present invention will be described in detail with reference to FIG. 3.

To the traffic information provision system.

In step 30, the location information providing terminal stores the second set time, the threshold speed, and a plurality of congestion causes. In step 31, the location information providing terminal starts counting.

In step 32, the location information providing terminal determines whether the second set time has elapsed. If the second set time has elapsed, the location information providing terminal moves to step 33. If the second set time has not elapsed, the terminal proceeds to step 32 and continues counting.

In step 33, the location information providing terminal measures the average speed during the second set time. That is, the average speed is measured using the distance from the start of counting to the time when the second set time elapses and the second set time. At this time, the distance between when the counting starts and when the second predetermined time elapses is not the linear distance but the distance that the actual location information providing terminal has moved.

In step 34, the location information providing terminal compares the average speed with the threshold speed. As described above, it is apparent that the threshold speed may be set differently depending on the driving section, the time zone and other factors. If the average speed is greater than or equal to the threshold speed, the location information providing terminal moves to step 35 to reset the time. If the average speed is smaller than the threshold speed, the location information providing terminal moves to step 36.

In step 36, the location information providing terminal displays a plurality of congestion causes on the display unit. As described above, the plurality of congestion causes may include a vehicle increase, traffic control, an accident, and the like. The location information providing terminal receives one congestion cause from a user among the displayed plurality of congestion causes. That is, the user selects one of the plurality of congestion causes displayed on the display unit of the location information providing terminal.

In step 37, the location information providing terminal transmits the received cause of congestion and the location information of the terminal to the traffic information providing system.

In step 40, the traffic information providing system determines whether information is received from the location information providing terminal. The traffic information providing system moves to step 41 if the information is received from the location information providing terminal, and moves to step 40 if the information is not received.

In step 41, the traffic information providing system determines whether the received information is location information delivered at a first predetermined time interval. The traffic information providing system moves to step 42 if the information received from the location information providing terminal is location information delivered at a first set time interval, and moves to step 44 if the location information is not.

In step 42, the traffic information providing system calculates a speed of a corresponding section by using the received location information. In step 43, the traffic information providing system stores the calculated speed and the section per.

In step 44, the traffic information providing system stores the location of the congestion and the cause of the congestion.

4 is illustrated as receiving location information at a first set time interval by the location information providing system, it may be desirable to receive the distance traveled by the location information providing terminal. That is, the location information providing system calculates the speed of the location information providing terminal using the actual traveled distance.

In step 52, the traffic information providing system calculates the speed for each section by using the stored speed information. That is, the traffic information providing system calculates the speed for each section by using the speed information received from the plurality of location information providing terminals.

In step 53, it is determined whether there is a section smaller than the second set speed among the sections. The second set speed may also be set differently according to the route section (highway, downtown, suburbs, etc.) and time zone in the same manner as the first set speed. The traffic information providing system moves to step 54 when the speed of the specific section is less than the second set speed, and moves to step 58 when the speed is greater than or equal to the second set speed.

In step 54, the traffic information providing system calculates a detour route using the stored information. In step 55, the traffic information providing system calculates a transit time of the detour route using the stored traffic information.

In step 56, the traffic information providing system compares the time required for the bypass route with the time calculated for the originally calculated route. As a result of the comparison, if the time required for the bypass route is small, the route information providing system moves to step 57.

In step 57, the traffic information providing system generates route information in which the originally calculated route is modified as a bypass route. In step 58, the route information providing system transmits the generated route information to the route information requesting terminal.

In step 61, the path information requesting terminal receives the optimal path, the detour path, the congestion section, and the congestion cause from the current point to the specific point.

In step 62, the path information requesting terminal displays the optimum path and the speed and time required for each section of the optimal path. In step 63, the route information requesting terminal determines whether detour route information for a specific section is requested from the user among a plurality of sections. If the detour path information is requested from the user, the path information request terminal moves to step 64, and terminates if the detour path information is not requested.

In step 64, the route information requesting terminal displays information about the bypass route requested by the user. Information about the detour route includes distance, speed and time of the detour route.

In addition, the route information requesting terminal may display route information received from the traffic information providing system for each section, and if the user selects a specific section, the route information request terminal may display an optimal route, a detour route, and a cause of congestion for the selected section. . That is, the user can obtain more detailed information by repeatedly selecting a specific section.
