As indicated by block 105, it is first measured how much traffic congestion is occurring on the road near the parking lot and near each inlet. As indicated by an arrow 125, based on this measurement result, a method to guide the car exiting the parking lot to a plurality of existing outlets is determined, and guidance is performed according to the determined method ( Block 107). Similarly, as shown by an arrow 126, a method to guide the car into which the plurality of vehicles are about to enter the parking lot is determined, and guidance is performed according to the determined method (block 109).

Further, as indicated by an arrow 127, based on the measurement result, the content of the guide display for the vehicle about to flow out from the parking lot is determined, and the display device installed in the parking lot or the parking lot network. (Block 108). Similarly, as indicated by arrow 128,
The content of the guide display for the vehicle about to flow into the parking lot is determined and displayed on the display device installed on the road near the parking lot (block 110).

If it is difficult to measure how much traffic congestion is occurring on the road near the parking lot and at each inlet, or predict in advance how much traffic congestion will occur in the near future. Therefore, when trying to provide guidance or guidance display that avoids traffic jams that would otherwise occur if left unattended, traffic jams near roads and entrances near parking lots, as shown in block 106, Guidance control similar to the above is performed using the prediction of.

As shown in block 101, from a plurality of outlets existing in a parking lot or a parking lot network,
Each outflow is measured and, as indicated by block 102, predicts how each outflow from each outflow will change in the near future. In addition, as shown in block 103, the inflow amount of each of the plurality of inflow ports in the parking lot and parking lot network is measured, and as shown in block 104, each inflow port to each inflow port is measured.

Hereinafter, arrows 121 to 124 and arrow 1 in FIG.
Details of the functions indicated by 29 to 132 and arrows 133 to 134 will be described with reference to FIGS. 10, 11, and 12, respectively.

FIG. 10 shows the functions indicated by arrows 121 to 124 in FIG. 1, that is, the measurement results and prediction results of the outflow amount of each outflow port, and the measurement results and prediction of the inflow amount of each inflow port. It is explanatory drawing of the method of predicting the traffic jam condition of the road near a parking lot and each inflow port vicinity in the present and the near future using a result.

First, the amount of outflow from each outflow port is measured using a sensor provided at the outflow port gate (block 1001). Also, using the actual data of the outflow amount shown in block 1021, how the outflow amount from each outlet will change in the near future is predicted (block 100).
2). The actual data of the outflow amount indicated by block 1021 is data obtained by collecting the outflow amount from each outlet for each day of the week and each hour. By using these measurement results and prediction results, what kind of trends will the leaked cars show after the leak, and what kind of trends will the cars that are expected to leak in the near future show? It is predicted whether to show (block 1003). At this time, the actual data of the trend of the outflow vehicle shown in block 1022 is used. this is,
Data obtained by tracking the trend of spilled cars after they were leaked.Statistically collected data by day of the week and time regarding the route that a vehicle leaked from each outlet follows with time. is there.

With respect to the inflow, the same operation as the outflow is performed. First, the amount of inflow to each inflow port is measured using a sensor provided at the inflow port gate (block 100).
4). In addition, the actual data of the inflow amount shown in block 1023 is used to predict how the inflow amount to each inflow port will change in the near future (block 1005). The actual data of the inflow amount shown by the block 1023 is data in which the inflow amount to each inflow port is statistically collected for each day of the week and each hour. Using these measurement results and prediction results,
It is predicted what kind of movement of the vehicle that is about to flow in before the inflow, and what kind of movement of the car expected to flow in the near future will show before the inflow (block 1006). ). At this time, the actual data of the trend of the inflow vehicle shown in block 1024 is used. this is,
Data obtained by tracing the trend of inflowing vehicles before inflow, and collecting statistics by day of the week and time regarding the route that the inflowing vehicle has flowed in along with time Is.

Further, not only the trends of outflow vehicles and inflow vehicles, but also the trends of vehicles passing near the parking lot are predicted.
What kind of trends are currently passing cars,
Also, it is predicted what kind of movement the vehicle expected to pass in the near future will show (block 1007). At this time, the actual data of the trend of passing vehicles shown in block 1025 is used. This is data obtained by tracking the trend of passing cars, and data that collects statistics by day of the week and time regarding what route the passing car followed with time Is.

In this way, when the trends of the cars flowing out from the respective outlets, the cars flowing into the respective inlets, and the cars passing near the parking lot are predicted, next, using these,
The expected traffic volume per unit time between each intersection is calculated hourly from the present to a point in the near future (block 1008). It is then used to calculate the expected speed of passage between each intersection (block 100).
9). Further, using this, the probability of stopping at a red light is calculated, the number of stopped vehicles at that time is calculated, and the average waiting time at the time of stopping is calculated based on that (block 10).
10). Using these, the average required time for passing between the intersections is predicted and calculated for each time from the present to a certain point in the near future (block 1011).

From the above, it is possible to predict the condition of traffic jams on all roads near the parking lot. On the other hand, as a special cause of traffic jams, it is also possible to predict traffic jams due to queues at each entrance. There is a need to do. Therefore, using the measurement results and prediction results of the inflow amount to each inflow port by the blocks 1004 and 1005, the occurrence status of the queue at each inflow port is predicted, and the average waiting time is calculated every hour ( Block 1012). There is no suitable method for traffic congestion information for an outflow vehicle other than providing general traffic congestion status near each outlet in an ambiguous form. Therefore, block 101
Using the average required time between each intersection, which was predicted and calculated in 1, calculate the average time required to leave a certain distance or more from each outlet, and based on that, calculate the overall time around each outlet. The congestion status is determined in the form of "congestion", "slightly congestion", "no congestion" (block 1013).
Then, this is used as traffic congestion information for the outflow vehicle.

On the other hand, as the traffic jam information for the inflowing vehicle,
It is conceivable to provide the information in a more specific form, such as displaying the estimated required time from the display device that displays the congestion information to each inflow port. Therefore, using the average required time between each intersection, which is predicted and calculated by the block 1011 and the average waiting time at each inlet, which is predicted and calculated by the block 1012, the estimated required time from each display device to each inlet is calculated. The time is calculated, and based on the calculated time, the traffic jam status to each inlet is judged in the form of "congestion", "slightly congestion", "no congestion" (block 1014). Then, the estimated required time from each display device to each inflow port and the traffic jam condition are used as traffic jam information for the inflow vehicle.

With the above-described method, the traffic congestion situation on the road near the parking lot and near each inflow port is predicted at present and in the near future by using the measurement results and prediction results of the outflow amount and the inflow amount.

FIG. 11 shows the function of the vehicles indicated by the arrows 129 to 132 in FIG. 1, that is, the outflow vehicle to each outflow port based on the prediction result of the traffic jam condition near the road near each parking lot and each inflow port. The guide method of the vehicle, the method of guiding the inflow vehicle to each inflow port, the content of the guide display for the outflow vehicle,
It is explanatory drawing of the method of determining the content of the guidance display with respect to an inflow vehicle.

First, a method of guiding an outflow vehicle and a method of determining the contents of the guidance display for the outflow vehicle will be described. As shown in block 1013 of FIG. 10, the general congestion status near each outlet is “congested” “congested”
The judgment is made in the form of "no traffic jam". By using this as traffic congestion information for the outflow vehicle, the method of guiding the outflow vehicle to each outlet and the content of the guidance display for the outflow vehicle are determined. Whether to display or not to display the guidance is determined as follows.

That is, it is judged whether or not a special situation such as an accident or road construction has occurred near a certain outlet (block 1101), and if it occurs, it is forced to avoid the corresponding outlet. Of the outflow vehicle is performed, and it is determined whether the concentration at a certain outlet is over the allowable range (block 1102). If the concentration is over the allowable range, the corresponding outlet is similarly determined. Forcible guidance of the outflow vehicle will be implemented so as to avoid it. If neither of the above applies, only the guidance display is displayed. Then, in the former case, the instruction as shown in FIG. 5 is displayed on the display device in the parking lot (block 1104), and in the latter case, the instruction shown in FIG.
The traffic congestion situation near each outlet as shown in (1) is displayed on the display device in the parking lot (block 1103).

The same applies to the method of guiding the incoming vehicle and the method of determining the content of the guidance display for the incoming vehicle. As shown in block 1014 of FIG. 10, the estimated required time from each display device to each inlet is calculated, and the traffic congestion status to each inlet is “congested”, “slightly congested”, “not congested”. It judges in such a form. These are used as traffic congestion information for incoming vehicles to determine the method of guiding the incoming vehicle to each inlet and the content of the guidance display for the incoming vehicle. Or,
The decision whether to display only the guidance is made in the same way as for the outflow vehicle.

That is, it is determined whether or not a special situation such as an accident or road construction has occurred near a certain inlet (block 1105), and if it occurs, it is compulsory to avoid the corresponding inlet. The inflow vehicle is guided in a specific manner, and it is determined whether the concentration at a certain inlet is above the allowable range (block 1106). Force inflow vehicle guidance so as to avoid it. If neither of the above applies, only the guidance display is displayed. And in the former case,
The instruction as shown in FIG. 9 is displayed on the display device on the road around the parking lot (block 1108), and in the latter case, as shown in FIG.
The estimated required time from each display device to each inflow port and the traffic jam condition as shown in FIG. 6 are displayed on the display device on the road around the parking lot in a guidance manner (block 1107).

FIG. 12 predicts the outflow amount and the traffic jam condition in consideration of the functions indicated by the arrows 133 to 134 in FIG. 1, that is, the guidance display result for the outflow vehicle, and
It is explanatory drawing of the method of predicting an inflow volume and a traffic jam condition, considering the guidance display result with respect to an inflow vehicle.

When this function is added, the outflow amount actual data shown in block 1021 in FIG.
Actual data of trend of outflow vehicle shown in block 1022, actual data of inflow amount shown in block 1023,
The actual data of the trend of the inflowing vehicle shown in block 1024 needs to be the statistical data collected for each guidance display result for the outflowing vehicle and the inflowing vehicle. Using each actual data aggregated in such a way, the forecast of the inflow and outflow amount and the trend of the inflow and outflow vehicles, considering the guidance display result,
Do the following:

That is, by using the actual data (block 1021 ') of the outflow amount collected for each guidance display result,
Congestion status guidance display results near each outlet (block 11
03) is taken into consideration, the outflow amount from each outflow port is predicted (block 1002 '), and the actual data of the outflow vehicle trends collected for each guidance display result (block 102).
2 ') is used to predict the post-spill trend of the outflow vehicle (block 1003'), taking into consideration the guidance display result (block 1103) of the traffic congestion situation near each outlet. In addition, the actual data of the inflow amount collected for each guidance display result
(Block 1023 ') is used to predict the amount of inflow to each inlet after taking into consideration the expected time required from each display device to each inlet and the result of guidance display of the traffic jam condition (block 1107). (Block 1005 ′), and using the actual data of the inflow vehicle trend data collected for each guidance display result (block 1024 ′), the guidance display result of the estimated required time from each display device to each inlet and the traffic jam condition Taking into account (block 1107), the behavior of the inflow vehicle before the inflow is predicted (block 1006 ').

As shown in this embodiment, a plurality of outlets,
Single parking lot with inflow port, single or multiple outflow port, multiple parking lots with inflow port, or multiple parking lots and vehicles connecting and connecting them to and from the parking lot pass through In a parking lot network consisting of aisles and having multiple outlets and inlets, the traffic congestion situation on the road around the parking lot is determined, and based on that, the content of the guidance display inside and outside the parking lot and the multiple outlets and outlets By deciding the method of guiding to the entrance, it is possible to perform guidance control on the entrance and exit of the parking lot so that smooth traffic is maintained around the parking lot.
