If it is determined that the vehicle 1 is in the continuous stop state, it is determined that the vehicle is not in the traffic jam state, and if it is determined that the mobile body 1 is not in the continuous stop state, the next determination operation is performed. The distance measuring unit 1
7 compares the moving distance measured per unit time and the maximum speed measured by the speed measuring unit 16 with a preset specified value, and when both the moving distance and the maximum speed are equal to or more than the specified value, Is determined not to be in a traffic jam.

Further, when it is determined that the traffic is not in the traffic congestion state, it is further determined whether or not there is an instruction that the traffic is in the traffic congestion at the time of the previous determination. Send a cancellation signal. If both the moving distance and the maximum speed are less than the specified values, it is determined that the moving body 1 is in a traffic jam state, and the information is transmitted to the center station 20. As a result, a case in which the moving body 1 is intentionally stopped, although it is not in a traffic jam, is separated. When transmitting the traffic congestion information, the data communication is a full-duplex (complete bidirectional) packet, and the mobile unit 1 receives the latest information regarding the traffic congestion from the center station 20 at the same time as providing the information. Good.

Next, the moving body 1 in the center station 20
The processing operation of the traffic congestion information transmitted from will be described.
The traffic congestion information transmitted from the mobile unit 1 is aggregated per unit time, each route of the mobile unit 1 is divided per unit distance, and the frequency of the "congestion" and "congestion elimination" information is determined within each block. To do. At this time, the parameters of unit time and unit distance are changed according to the number of moving bodies 1 in operation, and the number of samples in each block is adjusted so as to be a statistically sufficient value. Then, as shown in FIG. 14, the frequency of the traffic jam signal from the mobile unit 1 is compared with the frequency of the traffic jam elimination signal,
If the frequency of the traffic jam elimination signal is more than the frequency of the traffic jam signal,
It is determined that the traffic jam in the block has been resolved, and 1 is subtracted from the traffic jam parameter representing the traffic jam state in the block. Alternatively, if the frequency of the traffic jam elimination signal is less than the frequency of the traffic jam signal, the frequency of the traffic jam signal is compared with a preset standard value, and if the frequency of the traffic jam signal is less than the standard value, the traffic jam parameter is Not changed However, in this case, when a traffic jam signal is continuously recognized for two or more unit times, it is determined that a traffic jam condition has occurred, and 1 is added to the traffic jam parameter.

If the frequency of the traffic jam elimination signal is less than the frequency of the traffic jam signal, and the frequency of the traffic jam signal is compared with a preset value, the traffic jam signal exceeds the specified value. It is determined that the condition has occurred, and 1 is added to the congestion parameter. When the congestion parameters calculated this time are 0 or less by the judgment of each condition above, the congestion parameters calculated last time are updated to 0, and when the congestion parameters calculated this time are 2 or more, the congestion parameters calculated last time Is updated to 2, and otherwise, the traffic jam parameters aggregated last time are not updated. In this way, when the traffic congestion parameter aggregated and updated is 0, it is determined that the traffic is not in a traffic congestion state, and when it is 1, it is determined that there is a possibility of traffic congestion.
In the case of 2, it is determined that the traffic is congested.

FIG. 15 shows the display section of the traffic information 1 which is determined by the above-mentioned misjudgment reduction operation of the traffic information of the mobile 1 and processed by the traffic information processing operation of the center station 20. 12 is a display screen in FIG. On this screen, the current position of the mobile unit 1, map information of the surrounding area, and traffic jam information processed and communicated by the center station 20 are displayed. In order to expand the range of information to be displayed and the "System" key that overlaps with this display and gives instructions to various settings, information collection screens (detailed map information, weather information, etc., other service menus) and startup screens. "Enlargement" key, a "Reduction" key for reducing the range of information to be displayed, and a "***" key for instructing to change the type of traffic jam currently displayed.

The "***" key is used to display any one of the display of traffic jam information from a public information source, the traffic jam information provided by the mobile unit 1 or the map information only, not the traffic jam information. "***" is displayed at the time of each selection, and "public information", "terminal information" or "map information" is displayed. It is supposed to change in order. The operation in the manual scroll or locked state is the same as that in the basic screen of FIG. 2, but in FIG. 15, “lock” is selected.
There is no key display, and it is locked by touching the center of the screen, and (LOCK) is displayed at the upper center of the screen. In consideration of the reliability of the traffic jam information, the traffic jam information provided from the mobile unit 1 displayed on this screen basically has a parameter of 2 in the traffic jam information processing operation of the center station 20.
However, even when the parameter is 1, it may be displayed by changing the display color.
