Description

The utility model relates to the field of traffic control and can be used to control traffic at intersections with traffic lights in the presence of unstable pedestrian and traffic flows.

In conditions of an increasing flow of vehicles, the problem of road unloading is urgent, that is, reducing the number of traffic congestion (traffic jams) and traffic accidents, which is especially important for large cities during peak hours with a complex road network. At the same time, it is equally important to maintain a balance between the movement of both transport and pedestrians.

To solve the above problems, traffic lights are used from the countdown board (hereinafter - LLP), which shows the residual burning time of the green and / or red traffic signal.

The prior art design of the countdown board (RF patent No. 92981, 04/10/2010), comprising a housing having a control unit with a transceiver radio interface based on a microprocessor controller, as well as an LED matrix forming digital characters, while the control unit with a transceiver the radio interface is connected to the road controller and a dedicated software loading console for setting initial parameters.

When mounting on a traffic light object in the memory of a countdown time board with a transceiver radio interface for a traffic light object using a specialized remote control, the necessary initial parameters are entered, and then this parameter is also changed wirelessly only if necessary. After receiving information about the time remaining until the green light of the traffic light is on from the road controller, the countdown with the transceiver radio interface for the traffic light object displays the obtained value, and then the time is counted down to the value “0:00” or “00 ". Starting from 3 seconds, the display blinks at intervals of 1 time per second.

In this case, when the green light of the traffic light is lit, the last value stored and transmitted by the road controller will be displayed on the LLP. Such data is recorded by the road controller once at the end of the burning of one traffic light green cycle. When the number changes, from which a new countdown of the time for the LLP and a new burning cycle of the traffic light signal begins, the LED matrix fades for a while, after which the stored value is displayed on the LLP. This solution does not allow you to effectively regulate traffic when changing traffic conditions and the formation of traffic congestion or vice versa the rarefaction of the road. In other words, a system based on such an LLP does not adapt to the situation on the road, as a result of which traffic control is ineffective.

A known design of the adaptive countdown display (http://www.tvc.ru/news/show/id/43318, viewed 03/05/2018), adopted as the closest analogue to the claimed solution, which contains a housing with an LED matrix, while the panel is wired or wirelessly connected to the road controller, which collects and processes information from traffic sensors and thus controls the duration of the burning of traffic signals for transport and the duration of the countdown for pedestrians.

In this case, only the current situation on the road is analyzed in the road controller, and the last stored value is also transmitted to the LLP from the road controller. Therefore, as in the previous case, when the number from which a new countdown of the time starts at the LLP changes, the LED matrix fades for a while, after which the stored value is displayed on the LLP. Thus, this solution is ineffective in regulating traffic.

The technical result of the utility model is to create a countdown scoreboard design that has improved traffic control by displaying on it a pre-calculated predicted value of the time from which the countdown will begin.

The technical result is achieved by using the design of the countdown scoreboard for traffic control, comprising a housing, an LED matrix, an information processing module from the road controller, the input of which is connected to the road controller, while this information processing module transmits to the LED matrix the data calculated by the road controller taking into account the previous cycles of the countdown and which determine the new cycle of the countdown.

To transfer data from the road controller to the LLP information processing module, any known wired or wireless channels for data transmission can be used.

For data processing, the road controller uses at least two previous LLP operation cycles.

Data processing can take place in the PID controller as part of the road controller and using other algorithms that are suitable for regulating the movement of a road section.

Thus, unlike analogs, where the last memorized value is transmitted to the LLP from the road controller, in the claimed solution, data processing and calculations are performed continuously (continuously), due to which the information processing module contains information in advance on which date the return should begin countdown on the LLP in the next cycle. This allows you to turn on the LLP without a time delay, provide the traffic participants with up-to-date data and adjust the traffic situation.

The LLP contains a housing 1, an LED matrix 2, an information processing module 3 from a road controller 4, while the input of the specified module 3 is connected to the output of the road controller 4, and the output of the specified module 3 is connected to the input of the LED matrix 2.

The inventive countdown scoreboard works as follows.

Depending on the congestion of the road section, the initial burning time of the red and green traffic lights is set, the same indicators for the countdown time are set at the LLP, the number of burning cycles of the traffic signal of red and green lights is also determined, during which the traffic congestion will be monitored using traffic sensors the change in the duration of the LLP and traffic light cycle is calculated.

For example, on the busy section of the road, the time of burning of the green and red light signals t1 is set, while the same time in the reverse order to zero will be displayed on the LLP. The number of cycles for signal processing, for example, is set to four. During the first 4 periods of operation of the LLP and the burning of traffic signals of green and red t1, t2, t3, t4, which are all equal to t1, traffic sensors determine the number of vehicles on an adjustable section of the road in each of four time periods.

Based on the obtained data, the time of the fifth burning period of the LLP operation and the burning time of the next traffic signal t5 are calculated and adjusted. If during the first four lanes the road was busy and traffic sensors transmitted information about the ever-increasing traffic flow, then the next fifth time interval will be increased if it is green for transport and will be reduced if it is red for transport.

If during the fifth time period the traffic sensors transmitted information about the continuous flow of traffic, the traffic controller will process the information from the 2nd to the 5th time intervals and will further increase the operating time t6 of the LLP and the green light burning time for transport or reduce the time LLP operations and red light burning time for transport with the corresponding display on the LLP.

If the road was unloaded during the sixth time period t6 and the traffic sensors transmitted the relevant information to the road controller, then the time interval t1 is adjusted to reduce the operating time of the LLP and the burning time of the green traffic light for transport or increasing the operating time of the LLP and burning time red traffic light for transport with the corresponding display on the LLP.

In a similar way, the previous situation on the road is constantly taken into account for several burning cycles of the traffic signal with the calculation of the predicted operating time of the LLP in a new cycle.

As a result, the new design of the LLP can be used to create adaptive management systems, allowing to increase the efficiency of traffic and the safety of the road situation.
