Description
A MANAGEMENT SYSTEM OF VEHICULAR TRAFFIC ALONG A CARRIAGEWAY
FIELD OF THE INVENTION
The present invention relates to the technical sector concerning the management of vehicular traffic. In particular, the present invention relates to a management system of vehicular traffic along a carriageway.
DESCRIPTION OF THE PRIOR ART
A management system of vehicular traffic along a carriageway is known and comprises: a plurality of local data detecting and transmission units, which are distributed along a carriageway which each comprise: a detecting device which is arranged to detect a datum relative to an event that takes place along an associated portion of carriageway; an antenna; and a control unit which is connected to the detecting device, which is connected to the antenna and which is configured to transmit the datum relative to the event via the antenna; a plurality of mobile data receiving and data re-transmitting units, which are mobile along the carriageway and which each comprise: an antenna; a user interface; a memory; and a control unit which is connected to the antenna, which is connected to the user interface, which is connected to the memory and which is configured: to receive the datum relative to the event via the antenna; to provide the datum relative to the event to the user interface or to store the datum relative to the event in the memory; a remote data receiving and data re-transmitting unit, comprising: an antenna; and a control unit which is connected to the antenna and which is configured: to receive the datum relative to the event and to re-transmit the datum relative to the event via the antenna.
The management system of vehicular traffic along a carriageway is configured so that in the presence of connectivity between the local data detecting and transmission unit, comprising the detecting device which detected the datum relative to the event, and the remote data receiving and data re-transmitting unit, the datum relative to the event is transmitted to the remote data receiving and data re-transmitting unit which re-transmits the datum relative to the event
to the plurality of mobile data receiving and data re-transmitting units.
In detail, in the management system of vehicular traffic along a carriageway the detecting device of each local data detecting and transmission unit detects a datum relative to an event that takes place along an associated portion of carriageway (i.e., in a portion of carriageway close to the detecting device) and the relative control unit transmits to the remote data receiving and data re transmitting unit, where a connectivity is present, the datum relative to the event via the antenna. Further, in the management system of vehicular traffic along a carriageway the remote data receiving and data re-transmitting unit re transmits the datum relative to the event to the plurality of mobile data receiving and data re-transmitting units with the purpose of making available the datum relative to the event to the plurality of mobile data receiving and data re-transmitting units which are transiting along the carriageway so that a mobile data receiving and data re-transmitting unit, which is about to reach the associated portion of carriageway, will know in advance of the datum relative to the event that has taken place along the portion of carriageway.
A drawback of this management system of vehicular traffic along a carriageway is that, when there is an absence of connectivity between the local data detecting and transmission unit, comprising the detecting device which detected the datum relative to the event, and the remote data receiving and data re-transmitting unit, the datum relative to the event that took place along the associated portion of carriageway, will not be able to be communicated to the remote data receiving and data re-transmitting unit data and for this reason, the datum relative to the event will not be able to be communicated to one or more mobile data receiving and data re-transmitting units which is/are about to reach the associated portion of carriageway.
In other words, should an event take place at a predetermined portion of carriageway and the datum relative to the event were detected by the detecting device of a local data detecting and transmission unit, when there is an absence of connectivity between the local data detecting and transmission unit comprising the detecting device which detected the datum relative to the event and the remote data receiving and data re-transmitting unit, the mobile
data receiving and data re-transmitting units that are reaching the portion of carriageway will not possibly be priorly aware of the datum relative to the event and, therefore, of the event that has taken place in that portion of carriageway.
Consequently, the plurality of mobile data receiving and data re-transmitting units will not be aware of the events that have taken place along the carriageway of interest, before transiting at the carriageway.
SUMMARY OF THE INVENTION
In the light of the above, the aim of the present invention consists in obviating the above-mentioned drawback.
The above aims are attained by use of a management system of vehicular traffic along a carriageway according to claim 1.
The management system of vehicular traffic along a carriageway of the present invention is advantageously configured to transmit the datum relative to the management of vehicular traffic both in the presence and absence of connectivity: in fact, in the presence of connectivity, the datum relative to the management of vehicular traffic is transmitted to the remote data receiving and data re-transmitting unit so that it can re-transmit it; while in absence of connectivity, the datum relative to the management of vehicular traffic is transmitted to one or more mobile data receiving and data re-transmitting units which is or are in transit at the portion of carriageway in which the event took place so that it/they can memorise the datum in the memory and re-transmit it, after having passed beyond the portion of carriageway in which the event took place.
Therefore, should an event take place at the associated portion of carriageway, where there is absence of connectivity, the datum relative to the management of vehicular traffic will be transmitted by the local data monitoring and transmission unit, comprising the monitoring device which detected the datum relative to the management of vehicular traffic, to the mobile data receiving and data re-transmitting unit that is transiting along the associated portion of carriageway and which, in turn, at the moment in which it transits in
a portion of carriageway subsequent to the associated portion of carriageway and where there is presence of connectivity, will re-transmit the datum relative to the management of vehicular traffic to make it available to the plurality of mobile data receiving and data re-transmitting units.

The management system of vehicular traffic (1) along a carriageway is configured so that in the event of the absence of connectivity between the local data monitoring and transmission unit (20) comprising the monitoring device (2b) having the sensor which detected the datum relative to the management of vehicular traffic and the remote data receiving and data re transmitting unit (5), the one or more mobile data receiving and data re transmitting units (40, 4) which is or are in transit along the associated portion of carriageway (3a), memorises the datum in the memory (4c) and re transmits the datum after having passed beyond the portion of carriageway (3a) to another local data monitoring and transmission unit (200) or to the
remote data receiving and data re-transmitting unit (5) (see figures 1 and 2).
By management of vehicular traffic is meant management of the conditions in which the movement of one or more mobile data receiving and data re transmitting units (40, 4) can occur along a portion of carriageway.
Each local data monitoring and transmission unit (2) can be configured to transmit the datum relative to the management of vehicular traffic to the plurality of mobile data receiving and data re-transmitting units (40, 4) or to the remote data receiving and data re-transmitting unit (5).
Each mobile data receiving and data re-transmitting unit (40, 4) can be configured to transmit the datum relative to the management of vehicular traffic to the plurality of local data monitoring and data re-transmission units (2, 20, 200) or to the remote data receiving and data re-transmitting unit (5).
The sensor can detect a datum relative to a determined condition of the associated portion of carriageway (3a).
The plurality of mobile data receiving and data re-transmitting units (4, 40) can be mobile along the carriageway (3) in a determined travel direction.
The remote data receiving and data re-transmitting unit (5) can comprise a memory (5c) for memorising the datum relative to the management of vehicular traffic.
The remote data receiving and data re-transmitting unit (5) is preferably configured to re-transmit the datum relative to the management of vehicular traffic via the antenna (5a) to the plurality of mobile data receiving and data re transmitting units (4, 40).
In other words, the remote data receiving and data re-transmitting unit (5) can be configured to re-transmit the datum relative to the management of vehicular traffic via the antenna (5a) to the plurality of mobile data receiving and data re transmitting units (4, 40).
In the presence of connectivity between one local data monitoring and transmission unit (20) comprising the monitoring device (2b) in turn comprising the sensor that has detected the datum relative to the management of
vehicular traffic, and the remote data receiving and data re-transmitting unit (5), the datum relative to the management of vehicular traffic is preferably transmitted to the remote data receiving and data re-transmitting unit (5) and this re-transmits the datum relative to the management of vehicular traffic to the plurality of mobile data receiving and data re-transmitting units (4, 40).
The management system of vehicular traffic (1) along a carriageway can be electrically powered by a battery (not illustrated) or by electric current supply power cables (not illustrated) or by renewable energy sources (not illustrated).
Each local data monitoring and transmission unit (20) of the plurality of local data monitoring and data transmission units (2, 20, 200) can be arranged at an associated portion of carriageway (in figures 1 and 2 it is denoted by (3a) the portion of carriageway associated to the monitoring device (2b)).
The monitoring device (2b) of each local data monitoring and transmission unit (20) can be arranged at the associated portion of carriageway (3a).
It is specified that the expression “associated portion of carriageway (3a)” is intended to mean a predetermined portion of carriageway (3a) in which an event has taken place, which will be detected by the sensor of the monitoring device (2b) arranged at the portion of carriageway (3a) along the road safety barrier (6).
In other words, supposing a subdivision of the carriageway (3) into multiple portions of carriageway (3a, 3b), each local data monitoring and transmission unit (20) will be arranged at a portion of carriageway (3a) in such a way that the monitoring device (2b) can monitor an associated portion of carriageway (3a).
Each portion of carriageway (3a, 3b) can have an extension of 500 m in length.
The relative control unit (2d) of each local data monitoring and transmission unit (20) can transmit the datum relative to the management of vehicular traffic via the internet. By way of example, the transmission can be done via 4G or 5G.
The remote data receiving and data re-transmitting unit (5) can re-transmit the datum relative to the management of vehicular traffic directly to the plurality of mobile data receiving and data re-transmitting units (4, 40).
Alternatively the remote data receiving and data re-transmitting unit (5) can re transmit the datum relative to the management of vehicular traffic indirectly to the plurality of mobile data receiving and data re-transmitting units (4, 40), i.e. re-transmitting the datum relative to the management of vehicular traffic to the plurality of local data monitoring and data transmission units (2, 20, 200) which will re-transmit, in turn, the datum relative to the management of vehicular traffic to the plurality of mobile data receiving and data re-transmitting units (4, 40).
The re-transmission of the datum relative to the management of vehicular traffic by the remote data receiving and data re-transmitting unit (5) can taken place, for example, via the 4G or 5G network.
Each mobile data receiving and data re-transmitting unit (40) of the plurality of mobile data receiving and data re-transmitting units (4, 40) can be in communication with the others.
Further, each mobile data receiving and data re-transmitting unit (40) of the plurality of mobile data receiving and data re-transmitting units (4, 40) can be incorporated in a smartphone or a tablet (not illustrated).
By presence of connectivity it is meant that there is a mobile network coverage and that data transmission via the internet is therefore possible.
On the other hand, by absence of connectivity it is meant that there is not a mobile network coverage and data transmission via the internet is therefore not possible.
The remote wireless connection and the local wireless connection are preferably bidirectional.
The local wireless connection takes place using WiFi technologies.
Alternatively, the local wireless connection takes place using LoRa transmission technology.
The local wireless connection can take place using LoRa transmission technology, via the LoRaWAN communication protocol.
Also alternatively, the local wireless connection takes place using 5G.
The remote wireless connection can take place using 4G.
As an alternative it uses 5G.
It is specified that by “other local data monitoring and transmission unit (20)” is meant a successive local data monitoring and transmission unit (20) along the carriageway (3), respect to the local data monitoring and transmission unit (20) comprising the monitoring device (2b) in turn comprising the sensor which detected the datum relative to the management of vehicular traffic.
The control unit (5d) of the remote data receiving and data re-transmitting unit (5) can be configured to re-transmit the datum relative to the management of vehicular traffic via the internet.
Each local data monitoring and transmission unit (20) preferably comprises a memory (2c) for memorising the datum relative to the management of vehicular traffic (see figures 1-3).
Each local data monitoring and transmission unit (20) advantageously memorises the datum relative to the management of vehicular traffic and makes it available to the plurality of mobile data receiving and data re transmitting units (4, 40) in subsequent times.
The monitoring device (2b) of each local data monitoring and transmission unit (20) preferably comprises an impact sensor and/or a vehicular flow sensor and/or a visibilimeter.
The monitoring device (2b) advantageously detects whether there has been an impact against the associated portion of carriageway (3a) or if there are queues or slowdowns at the associated portion of carriageway (3a), or if there is poor visibility, due to banks of fog or poor weather, at the associated portion of carriageway (3a).
The plurality of local data monitoring and data transmission units (2, 20, 200)
is advantageously arranged on the same side of the carriageway (3) to communicate with the plurality of mobile data receiving and data re transmitting units (40, 4) which are transiting on the carriageway (3) in the same travel direction, with the aim of advising the one or more mobile data receiving and data re-transmitting units (40, 4) in arrival along the same travel direction.
Each mobile unit for receiving data and re-transmitting data (40) of the plurality of mobile data receiving and data re-transmitting units (4, 40) is preferably borne by a vehicle (7) transiting along the carriageway (3) (see figures 1-3).
By vehicle (7) is meant a mechanical means guided by a person responsible for the transport of persons, animals or things.
In this case, each mobile data receiving and data re-transmitting unit (40) of the plurality of mobile data receiving and data re-transmitting units (4, 40) can be installed on the vehicle (7).
Figures 1 and 2 schematically illustrate the management system of vehicular traffic (1) along a carriageway.
Figure 3 is a view alike to that of figure 1 , which illustrates that each local data monitoring and transmission unit (20) comprises a relative antenna (2a) and a relative control unit (2d).
The following is a description, with particular reference to figures 1 and 2, of the functioning of the management system of vehicular traffic (1) along a carriageway, object of the present patent application.
Let us suppose that an event occurs along a portion of carriageway (3a), which is associated to a monitoring device (2b) of a local data monitoring and transmission unit (20). Once the event has occurred, the sensor of the monitoring device (2b) of the local data monitoring and transmission unit (20) will detect a datum relative to the management of vehicular traffic, and thus relative to the event, and this datum will be transmitted by the relative control unit (2d), via the relative antenna (2a), to the remote data receiving and data re-transmitting unit (5), in the condition of presence of connectivity between
the local data monitoring and transmission unit (20), comprising the sensor of the monitoring device (2b) which has detected the datum relative to the management of vehicular traffic, and the remote data receiving and data re transmitting unit (5). The remote data receiving and data re-transmitting unit (5) will receive and re-transmit the datum relative to the management of vehicular traffic via the antenna (5a) to the plurality of mobile data receiving and data re-transmitting units (4, 40) which will receive the datum relative to the management of vehicular traffic (see figure 3).
Further, in the event of the absence of connectivity between the local data monitoring and transmission unit (20) comprising the sensor of the monitoring device (2b) which has detected the datum relative to the management of vehicular traffic, and the remote data receiving and data re-transmitting unit (5), the control unit (2d) of the local data monitoring and transmission unit (20) will transmit the datum relative to the management of vehicular traffic to the mobile data receiving and data re-transmitting unit (40) which is in transit along the associated portion of carriageway (3a), which mobile data receiving and data re-transmitting unit (40) stores the datum in the memory (4c) (see figure 1). At this point, when the mobile data receiving and data re- transmitting unit (40) goes beyond the portion of carriageway (3a) and will transit at a successive portion of carriageway (3b), where there is presence of connectivity and where another local data monitoring and transmission unit (200) is arranged, the unit will transmit to the local data monitoring and transmission unit (200) the datum relative to the management of vehicular traffic so that the latter can communicate the datum to the remote data receiving and data re-transmitting unit (5) which will receive and will re transmit the datum relative to the management of vehicular traffic via the antenna (5a) to the plurality of mobile data receiving and data re-transmitting units (4, 40) (see figure 2).
A management method of the vehicular traffic along a carriageway is described in the following, comprising steps of: providing a management system of vehicular traffic (1) according to any one of the above-described embodiments;
monitoring an associated portion of carriageway (3a) to detect a datum relative to the management of vehicular traffic via a local data monitoring and transmission unit (20) of the plurality of local data monitoring and data transmission units (2, 20, 200); in the event of a presence of connectivity between the remote data receiving and data re-transmitting unit (5) and the local data monitoring and transmission unit (20), carrying out following steps: transmitting the datum relative to the management of vehicular traffic of the associated portion of carriageway (3a) from the local data monitoring and transmission unit (20) to the remote data receiving and data re-transmitting unit (5), via a remote wireless connection; re-transmitting the datum relative to the management of vehicular traffic of the associated portion of carriageway (3a) from the remote data receiving and data re-transmitting unit (5) to one or more mobile data receiving and data re transmitting units (40, 4), via a remote wireless connection; in the event of an absence of connectivity between the remote data receiving and data re-transmitting unit (5) and the local data monitoring and transmission unit (20), carrying out following steps: transmitting the datum relative to the management of vehicular traffic of the associated portion of carriageway (3a) from the local data monitoring and transmission unit (20) to one or more mobile data receiving and data re transmitting units (40, 4) which is or are in transit along the associated portion of carriageway (3a), via a local wireless connection; memorising the datum relative to the management of vehicular traffic of the associated portion of carriageway (3a) in the memory (4c) of the one or more mobile data receiving and data re-transmitting units (40, 4); re-transmitting the datum relative to the management of vehicular traffic of the associated portion of carriageway (3a), from the one or more mobile data receiving and data re-transmitting units (40, 4) to another local data monitoring and transmission unit (200), via a local wireless connection, or to the remote
data receiving and data re-transmitting unit (5), via a remote wireless connection, after the one or more mobile data receiving and data re transmitting units (40, 4) has passed beyond the portion of carriageway (3a).
