[0008] The published patent application WO 2010 / 124138 A1 discloses a concept that is intended to enable improved predictions regarding future traffic flow.

[0009] Disclosure of the invention

[0010] The object underlying the invention is to provide a concept for efficiently monitoring construction site traffic on a construction site.

[0011] This object is achieved by means of the respective subject matter of the independent claims. Advantageous embodiments of the invention are the subject matter of respective dependent subclaims. According to a first aspect, a method for monitoring construction site traffic at a construction site is provided, comprising the following steps: planning a target construction site traffic for the construction site, determining an actual construction site traffic at the construction site, and

[0012] Comparing the planned target construction site traffic with the determined actual construction site traffic in order to monitor the determined actual construction site traffic for deviations from the planned target construction site traffic.

[0013] According to a second aspect, a system for monitoring construction site traffic of a construction site is provided, comprising: a planning device which is configured to plan a target construction site traffic for the construction site, a determination device which is configured to determine an actual construction site traffic of the construction site, and a comparison device which is configured to compare the planned target construction site traffic with the determined actual construction site traffic in order to monitor the determined actual construction site traffic of the construction site for deviations from the planned target construction site traffic.

[0014] According to a third aspect, a computer program is provided which comprises instructions which, when the computer program is executed by a computer, for example by the system according to the second aspect, cause the computer to carry out a method according to the first aspect.

[0015] According to a fourth aspect, a machine-readable storage medium is provided on which the computer program according to the third aspect is stored.

[0016] The invention is based on and incorporates the finding that the above-mentioned problem is solved by comparing the current traffic situation at the construction site (actual construction site traffic) with the planned traffic situation at the construction site (target construction site traffic) in order to determine any deviation between the current traffic situation and the planned traffic situation. Based on a determined deviation, one or more actions can be initiated or executed, for example.

[0017] For example, comparing the planned target construction site traffic with the determined actual construction site traffic provides the technical advantage of efficiently monitoring the determined actual construction site traffic for any deviations from the planned target construction site traffic. This provides the technical advantage of efficiently monitoring construction site traffic.

[0018] In one embodiment of the method, it is provided that in the event of a deviation of the determined actual construction site traffic from the planned target construction site traffic, in particular one lying outside a predetermined tolerance range, at least one of the following actions is controlled: Informing a traffic control center and / or an operator of the construction site and / or one or more road users currently and / or in the future participating in the construction site traffic and / or service personnel of the construction site about the deviation, Closing the construction site, Changing the planned target construction site traffic, Checking the planning of the target construction site traffic for the construction site, Using the deviation for future planning of further target construction site traffic for the construction site and / or for another construction site, Sending a recommended action to one or more road users currently and / or in the future participating in the construction site traffic, for example to minimize the deviation,Sending control signals for at least partially automated control of the lateral and / or longitudinal guidance of one or more motor vehicles currently and / or in the future participating in construction site traffic to the corresponding motor vehicle(s), for example in order to minimize the deviation.

[0019] This provides the technical advantage, for example, of being able to react efficiently to any deviation of the current traffic situation from the planned traffic situation.

[0020] Informing within the meaning of the description includes, for example, sending a message via a communications network, wherein the message includes the information regarding the deviation. A communications network includes, for example, a wireless communications network and / or a wired communications network. A wireless communications network is, for example, a cellular network or a WLAN network. A wired communications network is, for example, an Ethernet network.

[0021] Informing includes, for example, transmitting a radio signal that represents the information regarding the deviation. Such a radio signal can be a radio signal.

[0022] This provides the technical advantage, for example, that the traffic control center can take or implement efficient measures to respond to the deviation. The same applies analogously to the construction site operator and / or road users currently and / or in the future participating in construction site traffic. They can thus, for example, adapt their driving style or behavior accordingly to minimize the deviation.

[0023] Furthermore, by providing a recommended course of action, road users can be efficiently advised on how best to respond to the deviation. Sending appropriate control signals, for example, offers the technical advantage of efficiently and specifically influencing the lateral and / or longitudinal guidance of the vehicle in question, for example, to minimize the deviation. This provides particularly suitable actions to minimize a deviation, for example, and to generally respond efficiently to a deviation.

[0024] Sending within the meaning of the description includes, for example, sending via a communications network.

[0025] In one embodiment of the method, it is provided that the planning comprises specifying at least one target traffic parameter, so that the planned target construction site traffic is at least partially defined by the at least one target traffic parameter, wherein the determination of the actual construction site traffic comprises determining an actual traffic parameter comparable to the at least one target traffic parameter, wherein the comparison of the planned target construction site traffic with the determined actual construction site traffic comprises comparing the specified target traffic parameter with the determined actual traffic parameter in order to monitor the determined actual traffic parameter for deviation from the specified target traffic parameter.

[0026] This provides, for example, the technical advantage that planning can be carried out efficiently. According to this embodiment, it is therefore provided that the planned target construction site traffic is defined at least partially, in particular completely, by one or more target traffic parameters. This provides, for example, the technical advantage that the target construction site traffic is defined efficiently.

[0027] The fact that determining the actual construction site traffic involves determining an actual traffic parameter comparable to at least one target traffic parameter, with these two parameters being compared with each other as part of comparing the current traffic situation with the planned traffic situation, provides the technical advantage that the comparison can be carried out efficiently. By comparing specific parameters, for example, a deviation between the current traffic situation and the planned traffic situation can be efficiently determined.

[0028] In one embodiment of the method, it is provided that the at least one target traffic parameter is an element selected from the following group of traffic parameters: minimum speed for motor vehicles participating in construction site traffic, maximum speed for motor vehicles participating in construction site traffic, recommended speed for motor vehicles participating in construction site traffic, course of one or more lanes of the construction site, target trajectory to be driven by motor vehicles participating in construction site traffic, target travel path to be driven by motor vehicles participating in construction site traffic, wherein for the minimum speed or maximum speed or recommended speed, the actual traffic parameter is an actual speed of a motor vehicle participating in construction site traffic,where for the course of one or more lanes of the construction site or for the target trajectory to be driven or the target driving lane to be driven, the actual traffic parameter is an actual trajectory of a motor vehicle.

[0029] This provides the technical advantage, for example, of allowing the use of particularly suitable traffic parameters. In particular, the planned traffic pattern can be efficiently defined using the appropriate traffic parameters.

[0030] In one embodiment of the method, it is provided that monitoring data of a construction site monitoring system of the construction site are received, wherein the actual construction site traffic is determined based on the monitoring data.

[0031] This provides the technical advantage, for example, that actual construction site traffic can be determined efficiently.

[0032] Receiving within the meaning of the description includes, for example, receiving via a communications network.

[0033] In one embodiment of the method, it is provided that the construction site monitoring system comprises at least one drone for monitoring the construction site, which drone is controlled in such a way that it monitors the construction site while flying and transmits monitoring data based on the monitoring.

[0034] This provides the technical advantage, for example, that the construction site can be monitored efficiently.

[0035] The construction site monitoring system includes, for example, one or more environmental sensors that are spatially distributed within the construction site.

[0036] An environmental sensor within the meaning of the description is, for example, one of the following environmental sensors: radar sensor, LiDAR sensor, ultrasonic sensor, infrared sensor, magnetic field sensor and image sensor, in particular image sensor of a video camera.

[0037] Such environmental sensors are configured, for example, to detect their respective surroundings and output environmental data based on the detection. This environmental data describes the respective environment from the perspective of the corresponding environmental sensor.

[0038] For example, the construction site monitoring system comprises one or more spatially distributed induction loops. Such an induction loop is, for example, located in a roadway on the construction site. Such an induction loop is configured, for example, to detect the crossing of a motor vehicle and, upon detection, to emit a detection signal.

[0039] For example, the construction site monitoring system comprises one or more speed measurement systems spatially distributed within the construction site. Such a speed measurement system is configured, for example, to measure the speed of a road user, in particular a motor vehicle, and to output speed data based on the measurement, which represents the speed of the road user. Thus, monitoring data within the meaning of the description includes, for example, such speed measurement data and / or environmental data from one or more environmental sensors and / or a detection signal from an induction loop or detection signals from multiple induction loops.

[0040] In one embodiment of the method, it is provided that the construction site monitoring system comprises one or more environmental sensors that are spatially distributed within the construction site, which sensorily detect their respective environment and output environmental data based on the detection as monitoring data, wherein the environmental data describe the respective environment from the perspective of the corresponding environmental sensor.

[0041] This provides, for example, the technical advantage of efficiently monitoring the construction site. A drone, as defined in this description, is an unmanned aerial vehicle. A drone, as defined in this description, includes, for example, one or more environmental sensors.

[0042] In one embodiment of the method, it is provided that driving behavior data are received which describe a respective driving behavior of at least one motor vehicle participating in the construction site traffic, wherein the actual construction site traffic is determined based on the driving behavior data.

[0043] This provides the technical advantage, for example, of efficiently determining actual construction site traffic. The driving behavior data can be generated and transmitted by the vehicle itself. This means, for example, that the vehicle itself determines its driving behavior and transmits information about it, either directly to the system or, for example, to a cloud infrastructure, which then transmits the corresponding information to the system for monitoring construction site traffic.

[0044] In one embodiment of the method, it is provided that environmental data generated by at least one motor vehicle participating in the construction site traffic are received, which describe an environment of the respective motor vehicle participating in the construction site traffic, wherein the actual construction site traffic is determined based on the environmental data.

[0045] This provides, for example, the technical advantage of efficiently determining the actual construction site traffic. According to this embodiment, the motor vehicle, when participating in construction site traffic, uses its own environmental sensors to detect its surroundings, i.e., its surroundings, and generates environmental data based on this detection, which describes the surroundings of the motor vehicle. Thus, additional information regarding the current traffic situation is efficiently available, based on which the actual construction site traffic can be determined.

[0046] The phrase "at least one" means "one or more." A road user within the meaning of this description is, for example, one of the following road users: pedestrian, cyclist, motor vehicle, or motorcycle.

[0047] Statements made in connection with the method apply analogously to the system for monitoring construction site traffic in reverse. This means that system characteristics result analogously from corresponding process characteristics, and vice versa.

[0048] Technical functionalities of the method according to the first aspect thus result in particular from corresponding technical functionalities of the system according to the second aspect and vice versa.

[0049] In one embodiment of the method, this is a computer-implemented method.

[0050] The system according to the second aspect is, for example, programmed to execute the computer program according to the third aspect.

[0051] The method according to the first aspect is, for example, carried out or performed by means of the system according to the second aspect.

[0052] For example, the system according to the second aspect is configured to carry out all steps of the method according to the first aspect.

[0053] In one embodiment of the system according to the second aspect, a control device is provided which is configured to control at least one of the following actions in the event of a deviation, in particular outside a predetermined tolerance range, of the determined actual construction site traffic from the planned target construction site traffic: Informing a traffic control center and / or an operator of the construction site and / or one or more road users currently and / or in the future participating in construction site traffic and / or service personnel of the construction site about the deviation, Closing the construction site, Changing the planned target construction site traffic, Checking the planning of the target construction site traffic of the construction site, Using the deviation for future planning of further target construction site traffic for the construction site and / or for another construction site,Sending a recommended course of action to one or more road users currently and / or in the future participating in construction site traffic, for example, to minimize the deviation, Sending control signals for at least partially automated control of a lateral and / or longitudinal guidance of one or more motor vehicles currently and / or in the future participating in construction site traffic to the corresponding motor vehicle(s), for example, to minimize the deviation.

[0054] In one embodiment of the system according to the second aspect, it is provided that the planning device is configured to specify at least one target traffic parameter, so that the planned target construction site traffic is at least partially defined by the at least one target traffic parameter, wherein the determination device is configured to determine an actual traffic parameter comparable with the at least one target traffic parameter, wherein the comparison device is configured to compare the specified target traffic parameter with the determined actual traffic parameter in order to monitor the determined actual traffic parameter for deviation from the specified target traffic parameter.

[0055] In an embodiment of the system according to the second aspect, it is provided that the at least one target traffic parameter is an element selected from the following group of traffic parameters: minimum speed for motor vehicles participating in construction site traffic, maximum speed for motor vehicles participating in construction site traffic, recommended speed for motor vehicles participating in construction site traffic, course of one or more lanes of the construction site, target trajectory to be driven by motor vehicles participating in construction site traffic, target travel path to be driven by motor vehicles participating in construction site traffic, wherein for the minimum speed or maximum speed or recommended speed, the actual traffic parameter is an actual speed of a motor vehicle participating in construction site traffic,wherein the actual traffic parameter for the course of one or more lanes of the construction site, or for the target trajectory to be traveled, or the target travel path to be traveled, is an actual trajectory of a motor vehicle. In one embodiment of the system according to the second aspect, a receiving device is provided. The receiving device is configured, for example, to receive data, for example data as described above and / or below.

[0056] In one embodiment of the system according to the second aspect, a construction site monitoring system is provided which is configured to monitor the construction site and to output monitoring data based on the monitoring, wherein the receiving device is configured to receive the output monitoring data of the construction site monitoring system, wherein the determining device is configured to determine the actual construction site traffic based on the monitoring data.

[0057] In one embodiment of the system according to the second aspect, it is provided that the construction site monitoring system comprises at least one drone for monitoring the construction site, wherein the construction site monitoring system is configured to control the at least one drone such that it monitors the construction site while flying and transmits monitoring data based on the monitoring.

[0058] In one embodiment of the system, it is provided that the construction site monitoring system comprises one or more environmental sensors that are spatially distributed within the construction site, which are configured to detect their respective environment using sensors and to output environmental data based on the detection as monitoring data, wherein the environmental data describe the respective environment from the perspective of the corresponding environmental sensor.

[0059] In one embodiment of the system according to the second aspect, it is provided that the receiving device is configured to receive driving behavior data which describe a respective driving behavior of at least one motor vehicle participating in construction site traffic, wherein the determination device is configured to determine the actual construction site traffic based on the driving behavior data. In one embodiment of the system according to the second aspect, it is provided that the receiving device is configured to receive environmental data generated by at least one motor vehicle participating in construction site traffic, which environmental data describe an environment of the respective motor vehicle participating in construction site traffic, wherein the determination device is configured to determine the actual construction site traffic based on the environmental data.

[0060] The method according to the first aspect comprises, for example, a step of monitoring the actual construction site traffic based on the comparison step. In other words, monitoring the actual construction site traffic for a deviation of the actual construction site traffic from the planned target construction site traffic is provided. For example, the actual construction site traffic is monitored to determine whether it deviates from the planned construction site traffic. For example, in the event of a deviation, the extent or degree of the deviation is determined.

[0061] Construction site traffic within the meaning of the description refers in particular to traffic that moves through a construction site, for example driving, or generally that is located within a construction site.

[0062] Actual construction site traffic within the meaning of the description refers in particular to traffic that is currently moving through a construction site, for example driving, or generally which is located within a construction site.

[0063] Planned construction site traffic within the meaning of the description refers in particular to traffic that is intended to move, for example, drive, through a construction site according to a (construction site) plan. In other words, planned construction site traffic refers in particular to traffic that is intended to move, for example, drive, through the construction site according to a (construction site) plan. The (construction site) plan can therefore, for example, include traffic planning according to which traffic through the construction site is planned. One result of the corresponding planning is therefore a construction site (plan) or a traffic plan. Planned construction site traffic within the meaning of the description therefore refers in particular to traffic that is intended to move, for example, drive, through a construction site according to the (construction site plan or traffic plan).

[0064] Monitoring construction site traffic means, in particular, monitoring traffic within the construction site.

[0065] The invention is explained in more detail below using preferred embodiments. These show:

[0066] Fig. 1 is a flowchart of a method for monitoring construction site traffic at a construction site,

[0067] Fig. 2 a system for monitoring construction site traffic of a construction site,

[0068] Fig. 3 a machine-readable storage medium and

[0069] Fig. 4 shows another system for monitoring construction site traffic on a construction site.

[0070] In the following, the same reference symbols may be used for the same features.

[0071] Fig. 1 shows a flowchart of a method for monitoring construction site traffic of a construction site, comprising the following steps: Planning 101 a target construction site traffic for the construction site, Determining 103 an actual construction site traffic of the construction site and

[0072] Compare 105 the planned target construction site traffic with the determined actual construction site traffic in order to monitor the determined actual construction site traffic for deviations from the planned target construction site traffic.

[0073] Fig. 2 shows a system 201 for monitoring construction site traffic of a construction site, comprising: a planning device 203 which is configured to plan a target construction site traffic for the construction site, a determination device 205 which is configured to determine an actual construction site traffic of the construction site, and a comparison device 207 which is configured to compare the planned target construction site traffic with the determined actual construction site traffic in order to monitor the determined actual construction site traffic of the construction site for deviations from the planned target construction site traffic.

[0074] In one embodiment, it is provided that the planning device 203 and / or the determination device 205 and / or the comparison device 207 are part of a cloud infrastructure.

[0075] Fig. 3 shows a machine-readable storage medium 301 on which a computer program 303 is stored. The computer program 303 comprises instructions which, when the computer program 303 is executed by a computer, for example by the system according to the second aspect, cause the computer to execute a method according to the first aspect.

[0076] Fig. 4 shows a three-lane road 401 that runs horizontally and from left to right relative to the plane of the paper. This means that a given direction of travel for motor vehicles runs from left to right relative to the plane of the paper.

[0077] The three-lane road 401 thus includes a left lane 403, a center lane 405 and a right lane 407.

[0078] In the right lane 407 there is a first pothole 409 and a second pothole 411. In the middle lane 405 there is a third pothole 413. These three potholes 409, 411, 413 must be removed. This means that the two lanes 405, 407 must be repaired. In this respect, a section of the road 401 is defined, specified, or planned as a construction site. This section is marked with a curly bracket with the reference number 415. Within the area 415, a construction site 417 is therefore planned in order to repair the lanes 405, 407. Accordingly, a changed lane layout is specified, planned, or defined. This changed lane layout is defined by a solid line with the reference number 419. According to the changed lane layout of road 419, the three-lane road 401 narrows to two lanes before the first pothole 409.This means that the right lane 407 will be closed first. Two lanes remain available: the left lane 403 and the center lane 405. Then, according to the modified lane layout, the two-lane road will narrow to one lane. This leaves the left lane 403 for use by motor vehicles. The center lane 405 will be closed before the third pothole 413. This means that motor vehicles will have to merge into two lanes first, following the zipper principle, and then into just one lane, the left lane 403.

[0079] A construction site monitoring system 421 is provided, which includes a first drone 423 and a second drone 425. The first drone 423 includes a first video camera 427 comprising a first image sensor 429. The second drone 425 includes a second video camera 431 comprising a second image sensor 433.

[0080] The construction site monitoring system 421 further comprises a drone control device 435 configured to control the two drones 423, 425. The two drones 423, 425 can thus monitor the construction site 417 while flying and send video data based on the monitoring to the drone control device 435, which can, for example, evaluate the data and / or forward it for evaluation.

[0081] Furthermore, the construction site monitoring system 421 comprises a speed measuring system 437, which is configured to measure a motor vehicle speed of a motor vehicle traveling within the construction site 417.

[0082] The construction site monitoring system 421 further comprises a third video camera 439 and a fourth video camera 441. The third video camera 439 comprises a third image sensor 443. The fourth video camera 441 comprises a fourth image sensor 445. The two video cameras 439, 441 are stationary within the construction site 417 and also monitor their respective surroundings. Video data based on the corresponding monitoring is output by the video cameras 439, 441 for evaluation.

[0083] Within construction site 417, a first electronic traffic sign 447 and a second electronic traffic sign 449 are located. The first electronic traffic sign 447 is located to the left of the left lane 403 at the beginning of the modified lane layout. The second electronic traffic sign 449 is located to the right of the right lane 407 at the beginning of the modified lane layout. The two electronic traffic signs 447 and 449 specify a maximum speed for motor vehicles.

[0084] In the left lane 403, a first motor vehicle 451 is traveling, followed by a second motor vehicle 453 and a third motor vehicle 455. In the middle lane 405, a fourth motor vehicle 457 is traveling, followed by a fifth motor vehicle 459 and a sixth motor vehicle 461. In the right lane 407, a seventh motor vehicle 463 is traveling, followed by an eighth motor vehicle 465.

[0085] The respective direction of travel of these motor vehicles is indicated by an arrow with the reference number 467.

[0086] Motor vehicles traveling in the right lane 407 must first move or merge from the right lane 407 into the center lane 405 according to the changed lane routing. The eighth motor vehicle 465 failed to move from the right lane 407 into the center lane 405 in time before the changed lane routing. The eighth motor vehicle 465 thus crossed the solid line 419.

[0087] The same applies to the sixth motor vehicle 461, which is in the center lane 405 and also crossed the solid line 419 because it was unable to move from the center lane 405 to the left lane 403 in time according to the changed lane layout. One reason for this may be that the specified maximum speed, which was established during the planning of the construction site 417 and which is now displayed by the electronic traffic signs 447, 449, was too high to allow timely lane changes according to the changed lane layout.

[0088] For example, the speed measurement system 437 measures that the motor vehicles traveling in lanes 403, 405, 407 largely exceed the specified or planned maximum speed, in particular by a predetermined tolerance value.

[0089] By analyzing the video data from the video cameras, it can be determined that some motor vehicles, in this case the sixth motor vehicle 461 and the eighth motor vehicle 465, were unable to change lanes in time. In this respect, the current traffic situation at construction site 417 deviates from the planned traffic situation at construction site 417. In response to this, for example, the maximum speed that was originally planned can be changed. In this case, a reduction in the maximum speed is sensible. This means that, based on the comparison of the actual traffic situation with the target traffic situation, it is determined that there is a deviation that lies outside a specified tolerance range. This tolerance range can consist, for example, in the fact that motor vehicles are permitted to cross the solid line 419 to a certain extent.However, if you exceed the solid line 419 too far, there is a deviation outside the specified tolerance range.

[0090] In response, the planned speed limit is reduced. The reduced speed limit is then displayed on the electronic traffic signs 447, 449, prompting motor vehicles to slow down accordingly. This can, in turn, be verified by the speed measurement system 437. Furthermore, the video cameras can monitor the actual traffic, i.e., the current traffic situation, so that, based on the monitoring, it can be determined whether, based on the changed speed limit, motor vehicles can change lanes in time according to the changed lane guidance without crossing the solid line 419.

[0091] For example, a cloud infrastructure 469 is provided, within which a planning device 471, a determination device 473, and a comparison device 475 are implemented. The monitoring data from the video cameras and the speed measurement data from the speed measurement system 437 are sent, for example, to the cloud infrastructure 469, so that the actual traffic situation can be determined within it. Furthermore, the comparison step can also be performed in the cloud infrastructure 469.

[0092] Furthermore, for example, a local data processing device 477 can be provided, which is located in the vicinity of the road 401. This data processing device 477 can also be configured to carry out or perform the steps of determining and comparing. Thus, the monitoring data and the speed measurement data can be made available to the local data processing device 477, i.e., sent to it. Accordingly, for example, the local data processing device 477 can control the two electronic traffic signs 447, 449 such that they display the reduced speed limit. Furthermore, for example, the local data processing device 477 can determine a flight plan for monitoring the construction site 417 and send this flight plan to the drone control device 435. The drone control device 435 can then control the two drones 423, 425 based on the flight plan.

[0093] Thus, a further system 479 for monitoring construction site traffic of a construction site is disclosed, which in particular comprises the construction site monitoring system 421 and / or the local data processing device 477 and / or the planning device 471 and / or the determination device 473 and / or the comparison device 475.

[0094] For example, it can be provided that the motor vehicles are given recommendations for action based on the comparison step. Recommendations for action can, for example, recommend that the motor vehicles adjust their speed or their distance from the motor vehicle ahead in such a way that other motor vehicles can merge in a timely manner. For example, control signals for at least partially automated control of the lateral and / or longitudinal guidance of a motor vehicle can be generated based on the comparison and sent to the corresponding motor vehicle in order to specifically intervene in the vehicle guidance to enable another motor vehicle to merge in a timely manner.

[0095] For example, if it is determined that despite a reduced speed limit and / or despite targeted interventions in vehicle control and / or despite the recommended actions, construction site 417 will be closed. Subsequently, a redesign of construction site 417 could be planned. For example, the modified lane layout could be revised according to the redesign so that it covers even more distance to allow for lane changes before potholes. The solid line 419 would then have to be changed accordingly. Construction site 417 can then be reopened to vehicle traffic.Then, according to the concept described here, the current traffic situation can be compared with the newly planned target traffic situation and, based on the comparison, one or more actions can be controlled.

[0096] Determining actual construction site traffic includes, for example, determining whether vehicles driving through the construction site are following the planned lane path or are slightly avoiding it. Determining actual construction site traffic includes determining whether a vehicle and / or a person is standing within the construction site, for example, due to an accident.

[0097] In summary, the concept described here is based in particular on comparing current traffic conditions in the construction site with the planned traffic conditions, whereby one or more actions can be initiated or controlled as needed, i.e. based on the comparison. The planned traffic situation, i.e. the target traffic situation, which in the description is also referred to as target construction site traffic, is defined in particular during construction site planning. For example, it is defined or specified how fast motor vehicles are permitted to drive in the construction site and thus, for example, a maximum speed is specified or set. For example, a minimum speed is defined. For example, a recommended speed is defined. For example, it is defined which trajectories the motor vehicles should take.

[0098] For example, the definition of the target traffic situation can also be carried out after test drives within the construction site, in particular at different speeds, and in particular with an analysis of the optimal speed.

[0099] This means, for example, that it is planned that one or more test drives will be carried out within the construction site, whereby a maximum speed and / or a minimum speed and / or a recommended speed for driving through the construction site will be determined based on the one or more test drives.

[0100] The current traffic situation is recorded or detected, for example, via one or more of the following information sources.

[0101] For example, motor vehicles send driving behavior data describing their respective driving behavior to a cloud infrastructure and / or to a local data processing facility, which can also be implemented as a construction site information system. For example, motor vehicles generate internal environmental data that describes their respective environment and was generated using the vehicle's environmental sensors. This means that motor vehicles detect their respective environment using the vehicle's own environmental sensors and send environmental data based on the detection, for example, to the local data processing facility and / or to a cloud infrastructure. For example, a construction site monitoring system can be provided to monitor the construction site.

[0102] Based on this monitoring data, the comparison can then be carried out.

[0103] The construction site monitoring system, for example, monitors the construction site with stationary environmental sensors, which may, for example, only be intended for the duration of the construction site. Such environmental sensors include, for example, image sensors, radar sensors, LiDAR sensors, and / or ultrasonic sensors. For example, the construction site monitoring system includes induction loops and / or speed measurement systems.

[0104] Environmental sensors can also be arranged in a mobile manner, for example by one or more drones.

[0105] This means that, for example, traffic flow within the construction site can be analyzed based on the monitoring data.

[0106] This makes it possible, for example, to determine whether motor vehicles are driving through the construction site according to the planned traffic flow or whether they are deviating slightly from it. For example, based on the monitoring data, it can be determined whether motor vehicles and / or people are standing within the construction site, for example, due to an accident.

[0107] If current traffic conditions deviate from the planned traffic situation, particularly taking into account one or more defined tolerance ranges, then one or more of the following actions can be initiated or controlled:

[0108] Informing a traffic control center and informing road users, i.e., current or future road users, about construction site traffic. This information can be provided via traffic radio or mobile communications, for example. For example, this information can be provided via C-ITS technology. C-ITS stands for "Cooperative Intelligent Transport Systems."

[0109] For example, the construction site may be closed. For example, the traffic regulations for the construction site may be changed. For example, a planned maximum speed may be changed. For example, a planned minimum speed may be changed. For example, a planned recommended speed may be changed.

[0110] For example, a service personnel at the construction site can be informed so that they can check a problem that has occurred and, if necessary, correct or resolve it.

[0111] For example, the original planning can be reviewed.

[0112] For example, the results of the comparison can be used for future construction site planning. Thus, learning can be carried out based on the comparison for future construction site planning.

[0113] The embodiments and forms of embodiment described here can be combined with each other in any way, even if this is not explicitly described.
