Description

Technical Field

[0001] The present invention relates to an operation management system for construction vehicles for facilitating passing (giving way) of large vehicles such as construction vehicles, particularly on mountainous roads with a narrow road width and a single lane where it is difficult for vehicles to pass each other.

Background Art

[0002] Mountainous roads generally have many single-lane roads with a narrow road width assuming low traffic volume, etc. On such roads, there are many sections where it is difficult or almost impossible for large vehicles such as construction vehicles to pass each other. In order for large vehicles to pass each other in such sections, one of the passing vehicles needs to temporarily wait at a passing bay provided on the road and wait until the other vehicle passes.

[0003] In addition, mountainous roads have many winding sections where the view ahead is blocked, so drivers cannot visually recognize the presence, position, number, etc. of oncoming vehicles in advance. For this reason, encountering oncoming vehicles on mountainous roads not only poses a great danger to drivers, but also there is a problem that traffic congestion is likely to occur because they cannot quickly respond to avoidance or taking shelter when passing by oncoming vehicles.

[0004] By the way, as an invention of a traffic system for supporting safe driving of vehicles on mountainous roads, etc., for example, Patent Document 1 discloses an invention of a traveling vehicle support system that notifies a driver of the presence of oncoming vehicles in advance. s

[0005] ​Briefly explained, on a road in a mid-mountainous area where sections with narrow road widths and difficulty in ensuring visual recognition distances continue continuously, a first sensor for detecting oncoming vehicles approaching from one direction side, a second sensor for detecting oncoming vehicles approaching from the other direction side, a plurality of first displays installed between the first sensor and the second sensor for notifying the approach of oncoming vehicles from one direction side, and a plurality of second displays for notifying the approach of oncoming vehicles from the other direction side. Each detection signal is communicated by wireless communication using specific low-power radio in the 400 MHz band. The plurality of first displays sequentially transfer the received first detection signal from the first display at the forefront on one side to the first displays on the other side, and the plurality of second displays are configured to sequentially transfer the received second detection signal from the first second display on the other side to the second displays on one side.

[0006] As a result, even on mid-mountain roads where sections with difficulty in ensuring visual recognition distances continue continuously, drivers can drive safely by visually recognizing the presence of oncoming vehicles in advance.

Summary of the Invention

Problems to be Solved by the Invention

[0008] However, in the invention of the vehicle driving support system disclosed in Patent Document 1, in a section where the road width is narrow and it is difficult or almost impossible for vehicles to give way to each other, smooth driving of vehicles cannot be achieved. Therefore, it is difficult to quickly respond to avoidance or evasion when vehicles give way to each other, and there is a problem that traffic jams are likely to occur.

[0009] The present invention has been made to solve the above problems, and in particular, to smooth the passing of construction vehicles on a single-lane road such as a mountainous road where the road width is narrow and it is difficult or almost impossible for vehicles to pass each other. The purpose is to provide an operation management system for construction vehicles.

Means for Solving the Problems

[0010] The present invention is an operation management system for construction vehicles that smooths the driving of construction vehicles by transmitting commands regarding the necessity of waiting at one or more passing places located within a specific section to one or more construction vehicles traveling in the outbound direction and one or more construction vehicles traveling in the inbound direction on a route where it is difficult for construction vehicles to pass each other. It includes position information transmitting means for transmitting the position information of each construction vehicle to be managed to GNSS, a management server for receiving and managing the position information of each construction vehicle sent via the GNSS, standby command transmitting means for transmitting commands regarding the necessity of waiting at the one or more passing places to each construction vehicle from the management server, and standby command receiving means for receiving commands from the standby command transmitting means. In the management server, based on the position information of the passing places input in advance to the management server and the position information of each construction vehicle received, the necessity of waiting at the passing places for each individual construction vehicle is calculated so that the priority (such as priority for vehicles entering the work site, priority for uphill vehicles, etc.) and passing time of each construction vehicle in the specific section are optimized, and commands regarding the necessity of waiting are transmitted to each construction vehicle.

[0011] For the position information transmitting means and the standby command receiving means, an application installed in a mobile terminal installed in each construction vehicle or held by the driver of each construction vehicle can be used. As the mobile terminal, a smartphone, a tablet, a personal computer, or the like can be used.

[0012] Also, on the map displayed on the display means (electronic screen) of the mobile terminal held by each driver of the construction vehicles, a geopence using position information by GNSS is set so as to surround a certain area (area) including the position of the own vehicle, and the presence and driving points of other construction vehicles transmitted via the management server can be grasped in advance, thereby preventing in particular collision accidents with oncoming vehicles at curves with poor visibility and the like. Further, it can be configured to prompt attention by voice or alarm or the like when an oncoming vehicle approaches the own vehicle to a certain distance.

[0013] Furthermore, by setting a geopence in a certain area including the location of each refuge, it is possible to notify the vehicle that has entered the refuge earlier of the presence and distance of the construction vehicle coming from the front and make it wait.

[0014] Also, only the own vehicle and the oncoming vehicle are displayed on the display means (electronic screen) of the mobile terminal held by each driver of the construction vehicles, and the oncoming vehicle that has passed by the own vehicle and the following vehicle following the own vehicle are not displayed on the display screen (electronic screen) of the mobile terminal held by oneself, so that the presence and distance of the approaching oncoming vehicle can be quickly confirmed.

Advantages of the Invention

[0015] According to the present invention, it is possible to smoothly perform passing of vehicles in a specific section where it is difficult for large vehicles to pass each other on a single-lane and narrow road width road such as a mountainous road.

[0016] Also, thereby, it is possible to quickly respond to standby during passing of vehicles, so that traffic congestion caused by the inability to quickly respond to standby during passing of vehicles can be eliminated.

[0017] Also, by setting a geofence using GNSS position information so as to surround a certain area (region) including the position of the own vehicle on the map displayed on the electronic screen (liquid crystal screen) of the mobile terminal held by each driver of the construction vehicles, the presence and driving points of other construction vehicles transmitted via the management server can be grasped in advance, thereby preventing in advance a collision accident with an oncoming vehicle, especially at a curve with poor visibility.

[0018] Furthermore, by setting a geofence in a certain area including the location of each refuge point i, the construction vehicle that has entered the refuge first can be notified of the presence and distance from the approaching construction vehicle and made to wait. Also, while waiting at the refuge, the position and traveling speed of the oncoming vehicle can be confirmed in real time.

Modes for Carrying Out the Invention

[0020] FIGS. 1-3 illustrate an embodiment of the present invention. FIG. 1 illustrates a specific section of a road in a mountainous area where it is difficult or almost impossible for large vehicles such as concrete trucks to pass each other.

[0021] Figure 2 shows an operation management system for construction vehicles (hereinafter referred to as the "operation management system") that supports the smooth passing of a plurality of construction vehicles a1, a2,... traveling on the outbound lane of the mountainous road shown in Figure 1 and construction vehicles b1, b2,... traveling on the inbound lane. Figure 3 is an enlarged view of a part of the operation management system shown in Figure 2.

[0022] In a specific section of the mountainous road, when construction vehicles a1, a2,... traveling on the outbound lane and construction vehicles b1, b2,... traveling on the inbound lane pass each other, a plurality of waiting shelters I for one of the construction vehicles to wait are provided at multiple locations at intervals.

[0023] The operation management system 1 includes a position information transmitting means (hereinafter referred to as the "position information transmitting app") 3 that transmits the position information of its own vehicle to the GNSS 2 for each construction vehicle a1, a2,... and each construction vehicle b1, b2,..., and a management server 4 that receives and manages the position information of each construction vehicle a1, a2,... and construction vehicle b1, b2,... sent via the GNSS 2.

[0024] The position information transmitting app 3 is installed on a mobile terminal 5 such as a smartphone held by the drivers of each construction vehicle a1, a2,... and each construction vehicle b1, b2,..., and the position information of each construction vehicle a1, a2,... and each construction vehicle b1, b2,... is automatically transmitted to the GNSS 2 from the position information transmitting app 3 of each mobile terminal 5 in seconds (for example, every 1 second).

[0025] In addition, the position information of each construction vehicle a1, a2,... and each construction vehicle b1, b2,... received by the management server 4 and the position information of one or more waiting shelters I are automatically transmitted to the mobile terminals 5 held by the drivers of each construction vehicle a1, a2,... and each construction vehicle b1, b2,... respectively.

[0026] Note that the position information of the waiting shelter I is input in advance to the management server 4 in one or more. Also, the position information transmitting app 3 may be installed on a tablet or a personal computer provided in each construction vehicle a1, a2,... and each construction vehicle b1, b2,... respectively.

[0027] Further, the operation management system 1 includes standby command transmission means (hereinafter referred to as the "standby command transmission application") 6 that transmits commands regarding the necessity of waiting at one or more standby locations i to each construction vehicle a1, a2,... and each construction vehicle b1, b2,... from the management server 4, and standby command reception means (hereinafter referred to as the "standby command reception application") 7 that receives commands from the standby command transmission application 6.

[0028] The standby command reception application 7 is installed in a mobile terminal 5 such as a smartphone held by the drivers of each construction vehicle a1, a2,... and each construction vehicle b1, b2,.... Note that the standby command reception application 7 may be installed in a tablet or a personal computer provided in each construction vehicle a1, a2,... and each construction vehicle b1, b2,....

[0029] In such a configuration, based on the position information of one or more standby locations i input in advance in the management server 4 and the position information of each construction vehicle a1, a2,... and each construction vehicle b1, b2,... received by the management server 4, for each of the construction vehicles a1, a2,... and each construction vehicle b1, b2,..., the necessity of waiting at one or more standby locations i is calculated so that the passing time of each construction vehicle a1, a2,... and each construction vehicle b1, b2,... in a specific section becomes optimal.

[0030] Then, a command regarding the necessity of waiting at an optimal standby location i is transmitted from the standby command transmission application 6 provided in the management server 4 to one of the construction vehicles a1, a2,... or the construction vehicles b1, b2,.... The construction vehicle a1, a2,... or the construction vehicle b1, b2,... that has received the standby request command by the standby command reception application 7 temporarily waits at the standby location i.

[0031] As a result, the other of the construction vehicles a1, a2,... or the construction vehicles b1, b2,... can smoothly pass through the location where the standby location i is arranged.

[0032] For example, in the management server 4, the arrival times of the construction vehicle a1 and the construction vehicle b1 to their respective nearest shelters I are calculated from the speeds at their respective driving locations and the distances to the nearest shelters I, and a standby request command is transmitted to the construction vehicle a1 or b1 with the shorter arrival time to the respective nearest shelter I.

[0033] One of the construction vehicle a1 or the construction vehicle b1 that has received the standby request command temporarily waits at the shelter I. As a result, the other of the construction vehicle a1 or the construction vehicle b1 can smoothly pass through the location of the shelter I where one of the construction vehicle a1 or the construction vehicle b1 waits.

[0034] In addition, each driver of each construction vehicle a1, a2,... and each construction vehicle b1, b2,... sets geopences X1, X2,... and Y1, Y2,... using the position information by GNSS2 so as to surround a certain area (area) including the position of their own vehicle on the map displayed on the display means (hereinafter referred to as "electronic screen") 8 of the mobile terminal 5 held by each of them, thereby being able to grasp in advance the presence and driving location of oncoming vehicles approaching.

[0035] In this case, for example, if the geopences X1, X2,... and Y1, Y2,... are each set to 100 m, each driver of the construction vehicle can determine whether a construction vehicle coming from the front has entered the geopence while driving. If it has entered, even if the construction vehicle coming from the front cannot be visually recognized, especially at a curve with poor visibility, etc., a collision accident can be prevented in advance by driving slowly in advance, etc., and it is also possible to wait early at the nearest shelter I.

[0036] In addition, by setting a geopence Z in a certain area including the location of each shelter I, it is possible to notify the construction vehicle that has entered the shelter I first of the presence and distance of the construction vehicle coming from the front and make it wait.

[0037] In addition, on the electronic screen 8 of the mobile terminals 5 held by the drivers of each construction vehicle a1, a2, … and construction vehicles b1, b2, …, only the own vehicle, oncoming vehicles, and the refuge area i are displayed, and the oncoming vehicles that have passed by the own vehicle and the following vehicles following the own vehicle are not displayed on the electronic screen 8 of the mobile terminal 5 held by the driver himself / herself. By setting it this way, the presence and distance of approaching oncoming vehicles can be quickly confirmed.

[0038] In such a configuration, for example, the case where construction vehicle a1 and construction vehicle b1 pass by each other within a specific section of a mountainous road will be described.

[0039] When construction vehicle a1 and construction vehicle b1 enter the specific section, the operation management system 1 automatically activates, and the position information of construction vehicle a1 and construction vehicle b1 is transmitted from the position information transmission application 3 installed on the mobile terminals 5 held by the drivers of construction vehicle a1 and construction vehicle b1 respectively in seconds (for example, every 1 second).

[0040] Also, in the management server 4, based on the speed at each driving point of construction vehicle a1 and construction vehicle b1 and the distance to the nearest refuge area i, the arrival times when construction vehicle a1 and construction vehicle b1 reach their respective nearest refuge areas i are calculated.

[0041] Then, for the construction vehicle a1 or b1 with the earlier arrival time, a standby request command for the nearest refuge area i is transmitted from the standby command transmission application 6 of the management server 4 to construction vehicle a1 or construction vehicle b1. Then, by one of construction vehicle a1 or b1 that has received the standby command waiting at the refuge area i, the other of construction vehicle a1 and b1 can pass by smoothly.

Industrial Applicability

[0042] The present invention can eliminate traffic jams caused by the difficulty of passing each other between large vehicles such as construction vehicles in a single-lane and narrow-width road passing through mountainous areas, especially in a specific section of a road where it is difficult for vehicles to pass each other. na This can smooth the passing of vehicles by resolving traffic jams.
