Abstract

PURPOSE:To improve the convenience of driver's driving by automatically displaying traffic jam information on the spot when the road which is hardly congested is congested. CONSTITUTION:A vehicle detecting means 1 detects passing vehicles on the road and a traffic congestion information generating means 2 generates traffic congestion information on plural intersections on the road. An arithmetic processing means 5 stores a storage means 3 with the generated traffic congestion information together with current time inputted from a timer control means 4. The arithmetic means 5 calculates the traffic congestion occurrence rate of the intersections where the road is congested at the current time by using current-time traffic congestion information of several past days stored in the storage means 3. When the traffic congestion rate is less than a certain value, singular traffic congestion information is displayed on a road changeable mark 7 through a display command output means 6.

2. Description of the Related Art Conventionally, in a traffic information providing apparatus of this type, a variable road sign or the like at a point to be provided indicates, among traffic congestion information of a plurality of intersections where congestion is currently occurring, an intersection near the point to be provided. The congestion information was prioritized and automatically displayed.

[0003]

However, in the above-mentioned conventional traffic information providing apparatus, the road congestion may occur in the morning, evening, etc.
Traffic congestion information at the same intersection is very likely to be displayed at a specific location at a specific time, and it is very important for drivers to empirically know the traffic congestion occurrence location and time. The sex was low.
Due to circumstances such as detours, there has been an increasing demand for knowing unique traffic congestion information that is occurring at intersections that are different from usual.

The present invention solves such a conventional problem, and improves the convenience of the driver's driving by displaying the specific traffic congestion information that is usually generated at the points where the traffic congestion is unlikely to occur. It is an object of the present invention to provide a traffic information providing device that can be operated.

[0005]

In order to achieve the above object, the present invention comprises means for creating congestion information at a plurality of points on a road, and storage means for accumulating the congestion information at the current time.
An arithmetic processing unit that calculates the congestion occurrence rate at the point where the congestion is present at the current time from the congestion information at the current time for the past several days accumulated in the storage unit, and the result indicates that the congestion at the point where the congestion occurrence rate is low Display means for displaying information.

[0006]

Therefore, according to the present invention, the congestion information at a plurality of points on the road is created and stored in the storage means, and the calculation processing means stores the congestion occurrence rate at the point where the traffic is congested at the present time in the storage means. Calculated from the current time congestion information for the past few days. As a result, if the congestion occurrence rate at the point where congestion is currently occurring is low, that is, if there is a congestion at a point where congestion is usually hard to occur, congestion information at that point is automatically displayed on the display means. To display.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic block diagram showing a traffic information providing apparatus according to an embodiment of the present invention.

In FIG. 1, 1 is a vehicle detecting means for detecting a passing vehicle on a road, 2 is a traffic congestion information creating means for collecting data from the vehicle detecting means 1 and creating traffic congestion information, 3 is a traffic congestion occurrence situation, etc. A storage means 4 for accumulating is a time management means for managing the current time, a reference numeral 5 is an arithmetic processing means, the current time is taken in from the time management means 4, the traffic jam information is taken in from the traffic jam information creating means 2, and the taken traffic jam information is collected. The congestion information stored in the storage unit 3 or stored in the storage unit 3 is fetched, and the congestion occurrence rate is calculated from the congestion information. When it is determined that the congestion occurrence rate is a certain value or more, a control command is output. To do. Reference numeral 6 is a display command output means for outputting a variable sign display command in accordance with the control command of the arithmetic processing means 5, and 7
Is a road variable sign as a display output means for providing traffic information and the like to a driver or the like in response to a variable sign display command.

The above construction will be described in more detail below together with its operation with reference to the flow chart shown in FIG.

First, the traffic jam information creating means 2 fetches vehicle presence / absence data from the vehicle detecting means 1 and creates traffic jam information of a plurality of intersections (step 11). Next, the arithmetic processing means 5
Stores the current time from the time management means 4, loads the traffic jam information from the traffic jam information creating means 2, and stores it in the storage means 3.
Write the congestion information in the accumulation position corresponding to the current time of
Accumulate daily traffic jam information (step 12). Next, the arithmetic processing means 5 determines whether or not there is congestion in the congestion information of each intersection at the current time (step 13).
When the arithmetic processing unit 5 determines that there is a traffic jam, the storage unit 3
Read the congestion information at the current time for the past several days from to calculate the congestion occurrence rate. That is, the number of days of congestion occurrence is the dividend,
By performing division with the number of accumulated days as a divisor, the congestion occurrence rate can be obtained (step 14). Next, the arithmetic processing means 5 determines whether or not the congestion occurrence rate at each intersection in which congestion is occurring is below a certain value (step 1).
5). Then, it determines that an intersection having a traffic congestion occurrence rate of a certain value or less is a specific traffic congestion point, outputs a control command to the display command output means 6, and based on this, the display command output means 6 commands the display of specific traffic congestion information. Is output to the road variable sign 7 (step 16). The road variable sign 7 displays specific traffic congestion information according to the display command.

As described above, according to the above-described embodiment, it is possible to detect a traffic jam occurrence intersection where the road condition is different from usual and display it on the display device such as the road variable sign 7.

[0013]

As described above, according to the present invention, the congestion information at a plurality of points on the road is created and stored in the storage means, and the arithmetic processing means calculates the congestion occurrence rate at the point where the congestion occurs at the current time. It is calculated from the congestion information at the current time of the past several days accumulated in the storage means. As a result, if the congestion occurrence rate at the point where congestion is currently occurring is low, that is, if there is a congestion at a point where congestion is usually hard to occur, congestion information at that point is automatically displayed on the display means. To display. In this way, it is possible to automatically detect a traffic jam occurrence point where the road situation is different from usual and display the information of the traffic jam occurrence point on the display means such as road variable signs, so that more important traffic information can be provided to the driver. The convenience of driving can be improved.
