- the detection step is carried out by a disembarked sensor.
- the detection step is carried out by an on-board sensor.
- a second aspect of the invention relates to a vehicle traffic management system approaching an alternating traffic zone.
- the vehicle traffic management system approaching an alternating traffic area comprises a control unit, a transmitting unit, a first detection point and a second detection point, arranged to put:
- control unit is disembarked.
- the system comprises at least one off-shore sensor.
- the system comprises at least one off-shore server and / or a proxy.
- a third aspect of the present invention relates to a vehicle comprising a control unit arranged to implement the traffic management method according to the first aspect.
- the vehicle comprises a display.
- FIG. 1 is a diagram illustrating the operation of a vehicle traffic management method approaching an alternating traffic zone according to the invention.
- FIG. 2 is another diagram illustrating the operation of the vehicle traffic management method approaching the alternating traffic zone according to the invention.
- Figure 1 is a diagram illustrating the operation of a vehicle traffic management method 1, 2 approaching an alternating traffic zone 100.
- the management process is illustrated with two vehicles 1, 2. It is possible to extrapolate the operation for a greater number of vehicles 1, 2.
- the vehicles can be vehicles driven by a driver or autonomous vehicles (or autonomous shuttles), or vehicles circulating on its own site (eg: tramway), and / or any possible combination of these.
- the alternating traffic zone arranged so that vehicles cannot drive in the opposite direction in the alternating traffic zone.
- the alternating traffic zone may include a narrowing of the roadway. In other words, it is an area in which vehicles cannot travel together in two different directions; they can only travel together in the area in one direction, in particular because the road is not wide enough.
- the alternating traffic zone thus does not include an intersection.
- An intersection is an area in which two lanes intersect or meet.
- the alternating traffic zone does not include any crossroads, bifurcations or crossroads, that is to say no junction of lanes.
- the management method comprises a step consisting in detecting at least a first passage of a first vehicle 1 at the level of a first detection point.
- the vehicle 1 is detected either by a position detector on board the vehicle or by a detector unloaded on the roadway or on the road, upstream of the alternating traffic zone 100.
- the detector on the track can be an inductive loop or else else. a motion sensor, radar, lidar, or any suitable technology, in order to detect the position and / or speed of the vehicle.
- the management method comprises a step consisting in detecting at least a second passage of a second vehicle 2 at the level of a second detection point 20 located on a second side of the alternating traffic zone 100, the second side being opposite on the first side.
- the method further comprises a step consisting in determining optimum speeds of the first and / or second vehicle 1, 2 up to the alternating traffic zone 100 in order to avoid stopping of the first and / or second vehicle 1, 2 before the alternating traffic zone 100.
- the optimum speed of vehicle 2 can be set lower than its current speed so that it does not stop before the alternating traffic zone 100 (for example, a speed allowing it to increase its speed).
- the second vehicle 2 is a priority vehicle, and that it can have an optimum speed in order to pass first in the alternating traffic zone 100, and to reduce the optimum speed of the vehicle. other vehicle accordingly.
- first detection point 10 first detection point 10
- second detection point 20 successive detection points on the second side 21, 22
- optimal speeds per section for example between the successive detection points 21 and 22
- the optimum speeds are sent to vehicles 1, 2 so that they respect them.
- the optimum speeds can then be displayed or sounded to the attention of the driver for a vehicle being driven.
- the information on the optimum speed can be sent to the vehicle's navigation system so that the driver is informed about the speed to be respected.
- the optimum speeds can also be sent (by X2V for example) to the on-board computer of an autonomous vehicle so that it adapts the speed of the vehicle 1, 2 without direct human intervention.
- the optimal speeds are then instructions in the case of autonomous vehicles, instructions that the autonomous vehicle must respect.
- the types of communications used can thus be short wireless (Bluetooth, wifi, PC5, ITS G5, etc.) or long (satellite, cellular (3G, 4G, 5G), etc.) range.
- a server and / or a proxy aggregates all the data reported by the detectors or sensors.
- the distances between the detectors are known as they are installed on the road or at the edge of it. In the case of on-board detectors, the distances are then calculated.
- the measurement of the speed of the vehicle 1, 2 is recovered via the Autonomous Telematics Unit (BTA) of the vehicle 1, 2, by the sensors of the vehicle 1, 2.
- BTA Autonomous Telematics Unit
- the vehicle 1, 2 sends the data relating to its speed to the computer.
- Vehicle cruise control 1, 2 can be used in the case of an autonomous vehicle as well as in the case of a vehicle with a driver, for example equipped with cruise control with an option of optimum speed instruction.
- the successive detectors 11, 12, 21, 22 can make it possible to ensure that the driver of the vehicle 1, 2 has followed the instructions and possibly act accordingly by proposing a new optimum speed or by preventing access. to the alternating traffic area.
- alternating traffic zone 30 it is possible to detect the presence, position and speed of a vehicle in the alternating traffic zone by means of a detector within the alternating traffic zone 30. This detector at the same time.
- the interior of the alternating traffic zone 30 makes it possible to determine optimum speeds which are safe for vehicles 1, 2 so that vehicles 1, 2 which have not yet entered the alternating traffic zone 100 do not collide with the vehicle already present in the alternating traffic zone 100.
- FIG. 2 represents another diagram illustrating the operation of the method of managing vehicle traffic approaching the alternating traffic zone 100.
- the detectors 10, 11, 12, 20, 21, 22, 30, 31, 32 are diagrammatically illustrated in FIG. 2.
- the group of detectors comprises the first detection point 10, the successive detection points on the first side 11, 12 , the second detection point 20, the successive detection points on the second side 21, 22, the first entry detector of the alternating traffic zone 31, the second entry detector of the alternating traffic zone 32, and the detector inside the alternating traffic zone 30.
- the first detection point 10 as well as the successive detection points on the first side 11, 12, allow the detection of a vehicle (position and speed) approaching from the first side of the alternating traffic zone 100. This step is illustrated by the number 40 in figure 2.
- the second detection point 20, as well as the successive detection points on the second side 21, 22 allow the detection of a vehicle (position and speed) approaching from the second side of the alternating traffic zone 100. This step is illustrated by the number 50 in figure 2.
- the first alternate traffic zone entry detector 31 allows vehicle detection (position and speed) before entering the alternate traffic zone 100 on the first side. This detector 31 also makes it possible to measure the exit of the vehicle coming from the second side.
- the second alternating traffic zone entry detector 32 enables vehicle detection (position and speed) before entering the alternating traffic zone 100 on the second side. This detector 32 also makes it possible to measure the exit of the vehicle coming from the first side.
- the detector inside the alternating traffic zone 30 allows vehicle detection (position and speed) in the alternating traffic zone 100. This step is illustrated by number 60 in Figure 2.
- the method makes it possible to calculate in step 70 an estimate of the optimum speeds of the approaching vehicles and in the alternating traffic zone 100.
- the method enables the optimum speeds of the approaching vehicles and in the alternating traffic zone 100 to be sent to the vehicles in step 80.
