Description

Technical Field

[0001] The present invention relates to an operation management system for construction vehicles for smoothing the passing (yielding) of large vehicles such as construction vehicles 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. On such roads, there are many sections where it is particularly 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 wait temporarily at a turnout provided on the road until the other vehicle has passed.

[0003] In addition, mountainous roads often have many winding sections where the view ahead is blocked, so drivers cannot visually recognize the presence, position, and number of oncoming vehicles in advance. Therefore, encountering oncoming vehicles on mountainous roads not only poses a great danger to drivers but also makes it difficult to quickly respond to avoidance or turnout during passing, leading to traffic congestion.

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

[0005] Briefly explained, on a road in a mid-mountain area where sections with narrow road widths and difficult-to-secure sight 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 indicators 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 indicators for notifying the approach of oncoming vehicles from the other direction side are provided. Each detection signal is communicated by wireless communication using specific low-power radio in the 400 MHz band. The plurality of first indicators sequentially transfer the received first detection signal from the first indicator at the forefront on one side to the first indicators on the other side, and the plurality of second indicators are configured to sequentially transfer the received second detection signal from the first second indicator on the other side to the second indicators on one side.

[0006] Thereby, even on a mid-mountain road where sections with difficult-to-secure sight 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 the vehicle cannot be achieved. Therefore, it is difficult to quickly respond to avoidance or evacuation 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, it aims to provide an operation management system for construction vehicles that smooths the passing of construction vehicles on a single-lane road with a narrow road width, such as in mountainous areas, where it is difficult or almost impossible for vehicles to pass each other.

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 bays located within a specific section to one or more construction vehicles traveling in the forward direction and one or more construction vehicles traveling in the return direction on a specific section of a route where it is difficult for construction vehicles to pass each other, It includes a position information transmitting means that transmits the position information of its own vehicle to GNSS for each construction vehicle to be managed, a management server that receives and manages the position information of each construction vehicle sent via the GNSS, a standby command transmitting means that transmits commands regarding the necessity of waiting at the one or more passing bays to each construction vehicle from the management server, and a standby command receiving means that receives commands from the standby command transmitting means. In the management server, based on the position information of the passing bays input to the management server in advance and the position information of each construction vehicle received, the necessity of waiting at the passing bays for each individual construction vehicle is calculated so that the priority (such as priority for vehicles entering the 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 app 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 geop fence using position information by GNSS is set so as to surround a certain area (area) including the position of the own vehicle, so that the presence and driving points of other construction vehicles transmitted via the management server can be grasped in advance. In particular, it is possible to prevent a collision accident with an oncoming vehicle at a curve or the like with poor visibility. Also, it can be configured to prompt attention by voice or alarm when an oncoming vehicle approaches the own vehicle to a certain distance.

[0013] Furthermore, by setting a geop fence 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, on the display means (electronic screen) of the mobile terminal held by each driver of the construction vehicles, only the own vehicle and the oncoming vehicle are displayed, 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. By doing so, it is possible to quickly confirm the presence and distance of the approaching oncoming vehicle.

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, since it is possible to quickly respond to the standby during passing of vehicles, it is possible to eliminate traffic congestion caused by the inability to quickly respond to the standby during passing of vehicles.

[0017] In addition, on the map displayed on the electronic screen (liquid crystal screen) of the mobile terminal held by each driver of the construction vehicles, a geofence using GNSS position information is set so as to surround a certain area (region) 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 particularly preventing collision accidents with oncoming vehicles in curves with poor visibility and the like.

[0018] Furthermore, by setting a geofence in a certain area including the location of each refuge point i, it is possible to notify the construction vehicle that has entered the refuge first of the presence and distance from the oncoming construction vehicle and make it wait. Also, while waiting at the refuge, the position and traveling speed of oncoming vehicles 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 by 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] In addition, the operation management system 1 includes a 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 a 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 each driver 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 previously input 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 each construction vehicle 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 each construction vehicle a1, a2,... or construction vehicle b1, b2,.... The construction vehicle a1, a2,... or 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 vehicle a1, a2,... or the construction vehicle 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 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 the construction vehicles a1, a2,... and the construction vehicles b1, b2,... uses the position information by GNSS2 to set geopences X1, X2,... and Y1, Y2,... that 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, so that the presence and driving location of oncoming vehicles can be grasped in advance.

[0035] In this case, for example, if the geopences X1, X2,... and Y1, Y2,... are set to 100 m each, the driver of each 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, a collision accident can be prevented in advance by driving slowly in advance, and it can also wait at the nearest shelter I earlier.

[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 earlier 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 terminal 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 location 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 oneself. By setting it in this way, the presence and distance of 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 location i, the arrival times when construction vehicle a1 and construction vehicle b1 reach their respective nearest refuge locations i are calculated.

[0041] Then, for the construction vehicle a1 or b1 with the earlier arrival time, a standby request command at the nearest refuge location 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 location i, the other of construction vehicle a1 and b1 can pass by smoothly.
