Description

Technical field

The invention relates to the field of road safety, in particular to systems for providing road users with additional useful information, previously inaccessible to them, in real time, for making the best decision to perform maneuvers that pose an increased danger. In the National Security Strategy (Decree of the President of the Russian Federation dated July 2, 2021 No. 400), “improving road safety is a task aimed at achieving the goals of ensuring state and public security” (Chapter 47, clause 18). Most road traffic accidents (RTA) occur because, when performing potentially dangerous maneuvers, unexpectedly for the driver, additional factors arise that were not known at the beginning of the maneuver. In a short time, as a rule, these are seconds, drivers do not have time to react adequately to them, as a result, an accident occurs, often accompanied by injuries and deaths (according to the Minister of Internal Affairs V. Kolokoltsev, announced at the collegium of the Ministry of Internal Affairs in October 2021, In Russia over the past ten years, more than 220 thousand people have died in road accidents and more than two million have been injured). The ubiquity of wireless access networks, as well as the 5G mobile communication system adopted for implementation as part of the implementation of the National Program "Digital Economy of the Russian Federation", makes it possible to find technical approaches to solving this problem.

State of the art

A mobile application is known from the prior art that determines the geolocation of the user and warns of his approach to the railway tracks by turning on the alert signal on the mobile device (https://klops.ru/news/2018-11-07/183797-rzhd-razrabotala-prilozhenie -dlya-smartfonov-beregis-poezda-kotoryy-preduprezhdaet-o-priblizhenii-k-putyam, publication date 11/07/2018). The disadvantage of such an application is its low security due to the fact that there is no provision for alerting road users about other traffic events that pose an increased danger.

A known method for ensuring road safety (RU No. 2469890 C2 G08G 1/16, G01C 21/04, B60W 30/08, publication date 12/20/2012). The disadvantage of such a system is the complexity of its implementation due to the large number of devices included in its composition and the lack of solutions to alert road users about other traffic events that pose an increased danger.

Known automated system for road safety involving unmanned vehicles (RU 2735873 C1 2020, G08G 1/00). The disadvantage of such a system is the complexity of its implementation due to the large number of devices included in its composition.

A known system for monitoring compliance with the speed limit by transport, traffic rules, which uses a limited range of radio communication and a device for receiving and transmitting a radio signal as components of a system for tracking violators of traffic rules, speed limits on the road and monitoring road congestion (RU 2506646, publ. 02/10/2014).

A significant drawback of such a system is the lack of technical ability to transfer to road users the necessary useful information that affects the choice of the optimal solution when making potentially dangerous maneuvers.

A known system for monitoring and alerting workers on the tracks about the approach of a train using GSM mobile radio communications, supplemented by ISM band radio communications (RU 2467902 C1, B61L 23/06, publication date 27.11.2012). The disadvantage of such a system is the complexity of its implementation due to the large number of devices included in its composition and the lack of solutions to alert road users about other traffic events that pose an increased danger.

A well-known coordinate system for warning workers on railways about the approach of a train for a time of at least 50 seconds and at a distance of at least 5 km, using satellite radio navigation systems (Article "Coordinate control and warning system", authors Novikov V.G., Alabushev I.I., journal "Bulletin of VNIIZhT", No. 1, 2008, pp. 45-48).

The disadvantages of such systems are their complexity, a large number of additionally installed components. In addition, such systems are aimed at reducing the safety of workers on the railway tracks and do not apply to warning systems for road users about other traffic events that pose an increased danger.

The system for monitoring and warning of the approach of rolling stock was chosen as the closest analogue - the prototype (patent of the Russian Federation dated 03.08.2020 No. 2728967). The system comprises an onboard unit of the rolling stock, a user's mobile phone/smartphone and a server capable of receiving signals from the onboard unit and the user's mobile phone/smartphone. The user's mobile phone/smartphone contains an installed application that provides notification to the user in case of approaching rolling stock when the mobile phone/smartphone is near the railway tracks. The system additionally contains a mobile phone/smartphone of the rolling stock driver to determine the geolocation of the rolling stock in real time. The driver's mobile phone/smartphone is configured to receive and transmit signals to the server and contains an installed application that notifies the driver if the user's mobile phone/smartphone is near the railway tracks and when rolling stock approaches it. With the use of the system, an increase in the safety of the movement of trains and crews working on the railway tracks is achieved.

The disadvantage of the prototype is that its work is aimed at ensuring the safety of trains and crews working on the railway tracks, as well as for pedestrians whose route crosses the railway tracks and does not apply to warning systems for road users about other traffic events that pose an increased danger.

The technical problem solved by the claimed invention is the lack of advance information among road users necessary to make the best decision to perform a maneuver that poses an increased danger.

Disclosure of the essence of the invention

The technical result of the claimed invention is to improve road safety. The result is achieved by providing road users with additional information, previously inaccessible to them, in real time, in order to choose the best solution for performing maneuvers that pose an increased danger.

The technical result is achieved through the formation of a road safety system (Fig. 1), containing mobile devices of road users, with GSM-communication and GPS/GLONASS transceivers to determine the geolocation of road users in real time; data processing unit containing interconnected application server and GSM communication server and configured to receive signals from GSM communication transceivers and GPS / GLONASS from mobile devices of road users to determine information about their geolocation in real time relative to a road map with the subsequent determination of the speed of movement of road users with the mentioned mobile devices, additionally contains a server for calculating oncoming speeds, which performs the function of automatically broadcasting to road users the current geolocation of an approaching oncoming oncoming vehicle with a calculated oncoming speed for it (Fig. 2), including information about speeds , representing a danger at the current time to perform a maneuver, into a mobile application with navigation, while the application server is connected to the server for calculating the opposite speeds; devices (cameras) for determining the current speeds of vehicles installed on sections of roads with limited visibility (Fig. 3.4), connected to the server for calculating oncoming speeds and transmitting data on the speeds of vehicles in real time to the said server for calculating oncoming speeds, including the number of vehicles moving without mobile devices with an installed application and not connected to the described system; mobile devices of road users contain an installed navigation application that provides notification to a road user about approaching road sections with limited visibility, about the approach of other road users indicating the calculated oncoming speed by displaying the current traffic situation on the device screen with the addition of the mentioned alert elements .

Due to the use of GPS / GLONASS receivers as part of mobile devices of road users, it is possible to determine their location in real time. Due to the presence of a GSM transceiver, this information is transmitted online via the GSM network to the application server, where it is superimposed on the road map, and the speed of movement is determined.

Due to the presence of a server for calculating opposite speeds and a communication server and a server of mobile applications connected to it, it is possible to calculate the opposite speeds of road users, the possibility of exchanging data on location and oncoming speeds.

The server for calculating oncoming speeds, depending on the location and speed of road users, calculates the time for a safe maneuver and, based on the data received, promptly turns on an alert about the impossibility of its safe completion, which increases the vigilance of the driver who is about to make a maneuver and, therefore, increases safety traffic on a particular section of the highway.

Due to the presence of devices (cameras) for determining the current speeds of vehicles installed on sections of roads with limited visibility (Fig. 3.4), connected to the server for calculating oncoming speeds and transmitting data on the speeds of vehicles in real time to the said server for calculating oncoming speeds , additional information is provided on road sections with limited visibility, as the most dangerous sections, about oncoming speeds with road users, including those who do not have devices connected to the system.

Thus, the claimed system provides real-time provision of additional useful information to road users, previously inaccessible to them, for them to make the best decision when making a potentially dangerous maneuver, which increases road safety.

In particular cases, the implementation of the claimed invention, the system can be performed as follows.

The application of a mobile phone/smartphone/tablet/standard built-in navigator of road users is made with the ability to transmit voice recommendations to other road users.

The application of a mobile phone/smartphone/tablet/regular built-in navigator of road users is made with the ability to sound alert the user about the approach of vehicles with dangerous calculated oncoming speeds while blocking the broadcast of music, videos and a telephone conversation.

The application of a mobile phone/smartphone/tablet/regular built-in navigator of road users is made with the ability to notify other road users about the impossibility of driving a car for technical reasons.

The server for calculating oncoming speeds takes into account the increased dimensions of vehicles of road users to generate an alert for road users about a possible dangerous traffic situation at the start of a maneuver.

The server for calculating oncoming speeds takes into account the state of the road surface to generate an alert to road users about a possible dangerous traffic situation at the beginning of the maneuver, using the data received from the weather server.

Implementation of the invention

The traffic safety system works as follows.

Road users install a navigation application on their mobile devices (smartphones/tablets).

During the movement of vehicles in real time due to the navigation and communication module, the coordinates of their locations are determined. This module transmits the following data to the server: the direction of movement, location coordinates, the application server determines the speed of the train by changing the coordinates in time and superimposes the movement on the road map.

The server at the same time saves the received data, compares them with a road map and searches the database for objects of mobile devices containing a mobile application and located nearby. These data are transmitted to the counter speed calculation server to calculate and identify dangerous oncoming speeds of road users in order to provide them with additional useful information in advance that influences the adoption of the optimal decision on a potentially dangerous maneuver. The counter speed calculation server transmits the calculated data to the application server for their translation directly into the application on the mobile devices of road users. Mobile applications of mobile devices (smartphones/tablets/regular built-in autonavigators) receive such data from the server. Depending on the location and speed of road users, the time for a safe maneuver, such as overtaking, is calculated, and, based on the data received, an alert is activated in a timely manner about the impossibility of its safe completion, while blocking the broadcast of music, videos and a telephone conversation.

At the same time, the counter speed calculation server transmits the calculated data to the application server for their translation directly into the counter speed application with vehicles without a GSM communication transceiver and GPS / GLONASS, not connected to the system, the speed of which is determined by devices (cameras) for determining the current speed of vehicles installed on sections of roads with poor visibility.

At any time, a road user has the opportunity to see a map of roads with tracking the locations and speeds of road users who are close to him, for example, within a radius of 1-2 km (the size of the radius can be set by the user personally). Drivers of oversized vehicles have the option to display this data in the application for processing and taking it into account when calculating the safe time to complete a maneuver (for example, overtaking).

Road users have the ability to enable / disable the transmission / reception of voice recommendations to other road users. The traffic safety system has the ability to connect a weather server to the information processing unit to take into account data coming from it, for example, about rain, snow, fog, road surface conditions (wet, slippery) when calculating the time for the safe completion of the maneuver.

Example 1

Driver No. 1 is driving a car along the highway at a speed of 90 km / h, catching up with truck No. 2 traveling in the same direction. Truck #2 is moving at a speed of 60 km/h. Other road users No. 3, 4 are driving towards. Since there is no opportunity for overtaking at the moment, driver No. 1 reduces the speed to 60 km / h. After drivers No. 3, 4 have passed the section, driver No. 1 decides to overtake. At this point in time, the visibility of the road situation for him is significantly reduced, since the truck seriously limits the view, while driver No. 1 has to pick up speed to overtake, which also takes some time. The driver begins the overtaking maneuver and only at this moment begins to see car No. 5, which is driving towards. In a very short time, driver #1 needs to estimate the distance to the oncoming vehicle, the speed of its approach, and the ability of his vehicle to gain the necessary speed to safely complete the overtaking manoeuvre. If at the same time the truck is traveling with a trailer, then the dimensions of the truck are added to the assessment of the situation. If, after the start of the overtaking maneuver, it turns out that another truck is driving in front of the truck, then data on the distance between them is added to the assessment of the situation (road users do not always keep a safe distance, and in some cases this is not possible at all). In a short time (usually a few seconds), driver #1 needs to evaluate many factors in order to decide whether to continue the maneuver or to stop it. Such a quick analysis of the situation is not available to every even an experienced driver, since this set of factors can include, for example, fatigue, darkness, sun in the eyes, etc. It is these traffic situations, in which there is no advance information available to drivers to make the right safe decision, that are the cause of most road traffic accidents, including injuries and deaths.

Consider the same example, using the described system.

Driver #1 with a smartphone (app enabled) drives a car along the highway at a speed of 90 km/h and catches up with truck #2 with a smartphone (app enabled) going in the same direction. Truck #2 is moving at a speed of 60 km/h. Other road users No. 3,4 with smartphones go to the meeting (the application is included). Driver No. 1 sees all road users on the smartphone screen and reduces the speed to 60 km/h. After drivers No. 3, 4 have passed the section, driver No. 1 decides to overtake. At the same time, driver No. 1 will have to pick up speed to overtake. Car No. 5 with a smartphone is driving to the meeting (the application is included). The server for calculating oncoming speeds, taking into account the time required to gain speed when overtaking, taking into account the speed and dimensions of truck No. 2, and taking into account the speed of movement of the oncoming vehicle No. 5, calculates the total time for the overtaking maneuver and if it exceeds the time for which vehicle No. 1 and vehicle No. 5 with a mutual oncoming speed reaches the same point, which will be at least 10 meters (the indicator is indicated as an example and can change) in front of the moving truck No. 2, then the traffic situation is recognized as dangerous and broadcasts through the application server to the driver application No. 1 warning signal, for example: "stop overtaking, danger!". Driver #1 slows down and returns to his lane. The dangerous situation has been removed.

Example 2

Driver No. 1 is driving a car along the highway at a speed of 90 km / h, catching up with car No. 2 traveling in the same direction. car number 2 is moving at a speed of 80 km/h. Other road users No. 3, 4 are driving towards. Since there is no opportunity for overtaking at the moment, driver No. 1 reduces the speed to 80 km / h. After drivers No. 3, 4 have passed the section, driver No. 1 decides to overtake. At this moment, both cars No. 1 and No. 2 drive up to a section of the road, on which the descent begins after 1 km. Car No. 5 is driving towards at a speed of 90 km / h, hidden from the view of drivers No. 1 and No. 2 behind a fold in the terrain. For comfortable overtaking of car No. 2, driver No. 1 needs to pick up speed of at least 100 km / h, starting the maneuver, he picks up this speed. At this point, drivers #1 and #5 begin to see each other. Their counter speed is 190 km/h. The distance between them is already less than a kilometer, they will meet in 18 seconds. If driver No. 1 does not stop overtaking in this situation, then the probability of a traffic accident is very high.

Consider the same example, using the described system.

Driver No. 1 with a smartphone (the application is on) drives a car (Fig. 3) along the highway at a speed of 90 km/h, overtakes car No. 2 with a smartphone (the application is on) traveling in the same direction. Car #2 is moving at a speed of 80 km/h. Other road users No. 3, 4 with smartphones (the application is included) are driving towards. Driver No. 1 sees all road users on the smartphone screen and reduces the speed to 80 km/h. After drivers No. 3, 4 have passed the section, driver No. 1 decides to overtake. At this moment, both cars No. 1 and No. 2 drive up to the site, where the descent begins after 1 km. Car No. 5 (without a smartphone) is driving towards it at a speed of 90 km/h, hidden from the view of drivers No. 1 and No. 2 behind a folded terrain. This section is a section of roads with limited visibility, it has devices (cameras) for determining the current speed of vehicles that transmit real-time speed data to the server for calculating oncoming speeds. At the same time, the counter speed calculation server transmits the calculated data to the application server for their translation directly into the counter speed application with vehicles without a GPS and GSM communication transceiver that are not connected to the system. The server for calculating oncoming speeds, taking into account the calculated oncoming speed of 190 km/h and the distance between oncoming vehicles, recognizes the traffic situation as dangerous and broadcasts a warning signal through the application server to driver application No. 1, for example: “stop overtaking, danger!”. Driver #1 slows down and returns to his lane. The dangerous situation has been removed.

Example 3

Driver #1 with a smartphone (app enabled) drives a car along the highway at a speed of 90 km/h and catches up with truck #2 with a smartphone (app enabled) going in the same direction. Truck #2 is moving at a speed of 50 km/h. The road in this section has a long (for example, more than a kilometer) turn to the right (Fig. 4), as a result, the traffic situation is hidden from driver No. 1 for making a decision to overtake. Driver No. 1 does not overtake the truck; a convoy of cars may gradually accumulate behind the truck. In this case, in the absence of oncoming vehicles, the truck driver can take advantage of the possibility of transmitting voice recommendations to other road users, for example: “to the nearest oncoming 5 kilometers, you can overtake” (usually, for example, conscientious drivers, seeing the column that has accumulated behind them, in such cases flash 2-3 times with the right direction indicator without slowing down, but not everyone knows about this and not everyone does it). Driver #1, as well as other drivers following the truck, can use the advice to make a safe overtaking maneuver.

Thus, the work of the claimed system is aimed at reducing the number of accidents on roads that occur due to the lack of advance information from drivers in order to select the optimal solution for performing maneuvers that pose an increased danger.
