CZ33117U1 - An autonomous system for giving preference to road users through a light-controlled intersection - Google Patents

Description

Technical field

The technical solution concerns a system for addressing preferences in public transport, especially the components of the Integrated Rescue System (IRS), but also other selected road users such as public transport, passing through an intersection controlled by light signaling equipment (SSZ) and mutual communication of this system with the transport infrastructure system and the central traffic management system.

BACKGROUND OF THE INVENTION

The existing IRS preference system and public transport vehicles use only communication between the preferred vehicle and the SSZ controller to set up the SSZ. It uses a combination of vehicle positioning based on the Global Navigation Satellite System (GNSS) satellite positioning system or infrared beacons for positioning and a radio modem located in the vehicle and in the SSZ controller. As the vehicle passes through the radio-coordinate coordinate, it sends a preference request to the evaluation electronics located at the SSZ controller, which evaluates it and sets the appropriate preferred direction at the junction or SSZ crossing accordingly. Communication is thus only possible between the vehicle and the SSZ. The vehicles are not connected to any system and do not communicate with each other. In the case of GNSS malfunction or distortion or infradetector failure, the SSZ preference is not effectively enabled.

The essence of the technical solution

The above-mentioned deficiencies are largely eliminated by the technical solution of the autonomous system for the preference of the passage of road users through the light-controlled intersection, which consists of at least one local transmitter located near the light-controlled intersection / area other road users, as well as the transport headquarters and the transport infrastructure system, which are equipped with devices for mutual two-way communication.

The local transmitter consists of a stationary IR module and / or a GNSS unit and / or a C2X system.

The mobile device is comprised of an information receiver, an onboard computer control unit, a mobile preference control unit comprising a radio modem, or other bi-directional communication device with a junction / area light signaling module. The transport infrastructure system consists of a module for autonomous evaluation of data from the traffic center, from the SSZ controller, from the verification system, from databases with data on other road users and from the state of variable traffic signs.

An autonomous system for the preference of a traffic junction through a light-controlled intersection is based on communication between a local infrared transmitter (stationary IR module of the local transmitter) located near an SSZ-controlled junction and a vehicle receiver (IR receiver in the vehicle). The absence of a stationary IR module can be solved by a vehicle-mounted GNSS receiver or a C2X system (Cooperative Intelligent Transport System (C-ITS) that communicates between vehicles (C2C) or between vehicle and infrastructure (C2I)). The system is not limited to the preference of public transport or IRS, but also to other road users, which may be groups of cyclists, pedestrians, but, for example, an emergency vehicle that does not directly belong to IRS components,

However, it ensures emergency readiness in case of technical network failure, traffic accident or other selected road user taking advantage of the preferential claim at the crossing or junction fitted with SSZ.

In addition, mobile devices in vehicles or accessories of other road users are connected to the transport infrastructure system both by one-way and two-way communication, they also communicate with other road users with whom they exchange traffic information eg: current settings of variable traffic signs near the intersection, delays in the public transport vehicle according to its timetable, the speed of the vehicle affected by the level of traffic, the sudden deceleration of the surrounding vehicles, or the number of passengers carrying the vehicle. This information is evaluated in the data of the concentrator or unit on the traffic infrastructure or traffic controller of the SSZ, or at the headquarters, the traffic center will reset the SSZ and variable traffic signs to speed up the passage of the vehicle or road users having preferential entitlement or permission to cross the SSZ. The system includes a verification environment where traffic information requirements are verified and checked. Traffic information is further evaluated in the traffic center, which distributes it to other road users. Information transmission takes place over dedicated communication such as GSM (Global System for Mobile), LTE (Long Term Evolution), G5 (dedicated frequency for cooperative systems), IoT (Internet of Things), Wi-Fi or even private network and according to the specific case and the requirement for road users.

An autonomous system for the preference of road users through a traffic lights is connected to a traffic infrastructure system that autonomously evaluates traffic information obtained from other road users and from traffic signs, eg variable traffic signs (PDZ), eg traffic levels. Information can be retrieved and sent using the C-ITS standard or other data format. This information is compared and verified in the verification system. Subsequently, this information is processed at the traffic center and the traffic center also carries out the setting of the traffic lights at the intersection and, where appropriate, the corresponding traffic signs, before the road user passes through the registration points for sending preference requests and thereby achieves faster passage.

An autonomous system for the preference of traffic users through a traffic light intersection is designed for a traffic center which is made up of a central server and operates autonomously and / or for a traffic center which is made up of a dispatching center and operates on the basis of operator interventions.

The traffic central system provides information to other road users about the state of traffic in their surroundings or is directly managed and informed. Other road users modify their preference interventions by their own initiative, both at the level of their own infrastructure and directly by the transport headquarters according to the type of road.

The autonomous system for the preference of road users passing through the traffic lights with the connection to the transport infrastructure works on the basis of information from the transport infrastructure and the map background without the necessity to control people. This is ensured provided that control and information data is provided by own means of transport, but also from other road users with possible intervention from the transport center to the vehicle system. An autonomous system for the preference of road users crossing the traffic lights controls and is controlled from the traffic center based on the optimum algorithm for the selected location where it is located and independently decides on the passage and preference requirement.

Example of technical solution implementation

An autonomous system for the preference of a road user through a traffic light intersection consists of one local transmitter 1, which is located near the traffic light intersection, mobile devices 2 in vehicles, a traffic center 3 and a traffic infrastructure system 4 which are provided with devices for mutual two-way communication.

The local transmitter 1 consists of a stationary IR module and a GNSS unit and a C2X system, wherein the mobile device 2 consists of an IR receiver 5, a control unit 6 with connection to the onboard computer 7, a mobile preference control unit 8 containing a radio modem for two-way communication with the junction light signal module. The transport infrastructure system 4 consists of a module 9 for autonomous evaluation of data from the traffic center 3, from the SSZ controller 10, from the verification system 11, from databases 12 with data about other traffic participants and from the state of variable traffic signs.

The local transmitter 1 transmits the data set in the direction of the arriving vehicles. The data set contains information about the identification of the IR module of the local transmitter 1 and the exact location of the communication, logon and logout points that are important for setting up the SSZ. The mobile device 2 in the vehicle receives from the information receiver 5, in this embodiment an IR information receiver, from the stationary IR module of the local transmitter 1 the relevant information in the data file. The information is received and transmitted to the control unit 6, which is connected to the on-board computer 7. The control unit 6 calculates the distance traveled according to the distance of the check-in and check-out points. As it approaches a specified distance from the SSZ, it sends a defined data set to the SSZ controller 10 that contains the evaluation electronics via a radio modem, using a communication modem. The SSZ controller 10 then makes the SSZ settings. At the same time, the coordinates of the log-in and log-out points are stored in the vehicle control unit 6 for the individual intersections and junctions fitted with traffic lights. If a vehicle passes through these coordinates, a request for preferential entitlement to a specific SSZ is sent. The mobile device 2 also communicates directly with the traffic center by an element which subsequently sets priorities for road users directly, or by using a defined and activated scenario or by modifying algorithms and predictions at the superior level of its own control member (PDZ, SSZ controllers).

The traffic infrastructure system 4 evaluates traffic information that is obtained from other road users and from traffic signs equipment (for example, variable traffic signs, but also other road users and traffic infrastructure). Depending on the traffic situation, priority crossings or sections with variable traffic signs are subsequently allowed for selected traffic participants according to a predefined preference system. Information is collected and sent by the C-ITS standard. Furthermore, information from the vehicle is sent to the system, for example about the delay of the public transport line compared to the timetable, about the number of passengers transporting and about environmental influences (rain, fog, temperature). Also, other information is sent according to the type of road user, such as arrival time, speed limit, etc. This information is compared and verified in the verification system 11. Subsequently, this information is processed in the module 9 for autonomous evaluation of data from the traffic center 3 and at the same time the traffic center 3 carries out the SSZ at the intersection before the vehicle passes through the registration points for sending the preference request in the ways mentioned above. By means of the transport infrastructure system 4, information on the state of traffic in their surroundings is transmitted to other road users and is directly managed and informed. Other road users modify their preference interventions, both at the level of their own infrastructure and directly by the transport center, depending on the type of road.
