Description

  The present invention relates to a stop area vehicle occurrence area detection program, a stop state vehicle occurrence area detection apparatus, and a stop state vehicle occurrence area detection method.

  One of the major themes in road administration is to remove the factors that stagnate traffic flow. As a factor that stagnates the traffic flow, for example, there is a truck that generates a waiting time for waiting for the order of loading or unloading work and stops the vehicle on the road. In addition, there is a taxi that stops a vehicle on the road in order to wait for passengers.

  Therefore, in order to identify traffic congestion points that stagnate the traffic flow, the geographical distribution of the location information is based on the location, time, and speed operation information obtained by the operation recorder such as a digital tachograph mounted on the truck. A method has been proposed in which a location exceeding a predetermined density is detected as a traffic jam location (see, for example, Patent Document 1).

  However, when a truck waits for a load, the vehicle stops on the road around the departure point or arrival point such as a truck terminal, parks or stops, or while traveling around several kilometers around the departure point or arrival point It may slow down or run. For this reason, it is not easy to identify points where traffic is delayed due to waiting for cargo, and it is difficult to determine the priority of points where urban development such as securing a parking space for trucks is required. There is.

  In one side, it aims at providing the generation | occurrence | production area detection program of the stop state vehicle which can detect an area with many vehicles in a stop state.

  In one embodiment, the generation area detection program for a stopped vehicle is obtained for each divided area obtained by dividing a predetermined area by a predetermined range based on operation information of position, time, and speed collected from the vehicle. The number of stopped vehicles that are in a predetermined stopped state in a period is counted, and the divided areas in which the counted number is equal to or greater than a predetermined value are detected.

  In one aspect, it is possible to provide a stop state vehicle occurrence area detection program capable of detecting an area where there are many stopped vehicles.

The stop state vehicle generation area detection device 100 is a device that detects an area where there are many stop state vehicles that may stagnate the traffic flow.
A stop state vehicle is a vehicle that is in a predetermined stop state. For example, not only vehicles that are parked on the streets around the truck terminal and are completely stopped, but also vehicles that run slowly and run around the circumference of the truck terminal in order to load or unload the vehicle. Including. For this reason, in this embodiment, the predetermined stop state is (1) a state where the vehicle is continuously stopped at a speed of 0 km / h for 5 minutes or more, and (2) a slow drive at a speed of 5 km / h or less is continued for 10 minutes or more. It is defined as at least one of a running state and (3) a state where traveling at a speed of 30 km / h or less continues for 20 minutes or more in a range wider than a predetermined range. The state (2) can be simply referred to as “slowing state”, and the state (3) can also be referred to as “second slowing state”.
In the present embodiment, the predetermined stop state is as described in (1) to (3). However, the present invention is not limited to this, and can be changed as appropriate according to the road conditions.

  In order to detect an area where there are many stopped vehicles, as shown in FIG. 1, the generation area detecting device 100 for stopped vehicles is operated from operation monitoring terminals 310, 410, 510 mounted on the vehicles 300, 400, 500. The operation information of the position, time, and speed is collected via the network 200.

As a result, it is possible to identify the area α where the city maintenance such as securing a parking space should be performed.

Further, by adding identification information for identifying whether or not the vehicle is loaded with luggage to the operation information, by counting the number of stopped vehicles whose identification information has been changed in a predetermined period for each area α, It is possible to clearly detect the area α where the loading or unloading work has been performed.
When the loading or unloading work is performed, the identification information indicates that the “loading state (actual vehicle)” is obtained by pressing the “actual vehicle / empty vehicle button” installed in the operation monitoring terminals 310, 410, 510. "And" Unloading state (empty car) ".
The identification information is changed to either “loading state (actual vehicle)” or “unloading state (empty vehicle)” by determining whether or not the load is loaded on the loading platform of the vehicle using various sensors. You may make it do.

The stop state vehicle generation area detection device 100 sets an area β that includes the detected area α and is wider than the area α (hereinafter, may be referred to as a “second divided area”), for each area β. In addition, it is possible to count the stopped vehicles for a predetermined period, and to detect an area β where the obtained counting result is a predetermined value or more. Accordingly, it is possible to detect the area β in consideration of the stopped vehicle that circulates around the track terminal or the like, for example, it is possible to detect an area where there are many trucks in the waiting state.
