Description

Information processing method and device based on traffic management, traffic management system

technical field

The invention relates to the communication field of the Internet of Things, in particular to an information processing method and device based on traffic management, and a traffic management system.

Background technique

At present, the traffic management department usually adopts the mode of placing traffic signs on the side of the road to remind the driver to pay attention to the traffic situation on the current road section and the traffic prohibition behavior on this road section. The traffic instruction information on the traffic sign needs to be obtained by the driver through visual observation. If it is blocked by obstacles, or encounters extreme weather such as heavy fog, rain and snow, it is not easy to obtain through visual observation. At the same time, because the driver is highly concentrated while driving, when the position of the signboard is not obvious or the driver is distracted, he may not be able to observe the surrounding signboards, resulting in omissions of information reception and hidden dangers to driving safety.

In order to ensure the accuracy of information acquisition and reduce the impact of bad weather, some traffic signs have been upgraded to electronic signs with liquid crystal display. For example, some traffic signs use radio frequency identification (Radio Frequency Identification, referred to as RFID) technology to achieve and pass The communication of the vehicle completes the process of notifying the driver of the traffic instruction information, but this method also has defects: (1) The communication distance of RFID is relatively short, generally a few meters or more than ten meters, and it is difficult to help the driver in a long distance. (2) At present, RFID has not formed an international unified communication standard, and there are application barriers between RFID systems of different manufacturers, which may easily lead to the failure of obtaining traffic information.

In actual traffic management, in addition to informing the driver of traffic instructions, the traffic management department also needs to obtain timely traffic violation information during the driving process of the driver. At present, for the acquisition of traffic violation information, manual, camera, or ground sensing are mostly used to achieve:

Most traffic violation information is detected and obtained by installing cameras at fixed locations or on related vehicles to detect and obtain the driver's vehicle operation behavior (such as illegal lane occupation, speeding, etc.), and then manually analyze the video obtained by the camera. Determine whether the vehicle operation behavior constitutes a traffic violation. This method has high limitations: first, the shooting range of the camera is limited. If the detection range is large, multiple cameras need to be configured for auxiliary detection, resulting in high installation costs; second, the shooting resolution of the camera is extremely easy Affected by factors such as light and environment, it is difficult to play its role at night or in extreme weather conditions such as rain and snow. Finally, artificial image recognition consumes a lot of manpower, and the processing efficiency is low. Moreover, even if automatic image recognition technology is used to analyze and identify videos, the process is relatively complicated and the cost is relatively high.

For the method of burying induction coils under the ground of a fixed road section to determine traffic parameters such as vehicle speed in the road section and then confirm whether there are traffic violations such as speeding, since induction coils need to be buried on the ground, there is a secondary impact on the ground. First construction, subsequent upgrades are extremely difficult defects.

In order to facilitate the understanding of the traffic management-based information processing method provided by the above-mentioned embodiments, the implementation process of the above-mentioned traffic management-based information processing method will be further described below in conjunction with the accompanying drawings and preferred embodiments.

In order to realize the above-mentioned information processing method based on traffic management, this preferred embodiment provides a traffic management system architecture, please refer to Figure 5 (Figure 5 is an architecture diagram of a traffic management system according to a preferred embodiment of the present invention), as shown in Figure 5 , the system architecture includes: an intelligent traffic management platform located at the far end, an RSU set at an intersection or on the roadside, and a vehicle with a functional unit with information processing capabilities inside. In this preferred embodiment, each The interior of the vehicle can be pre-set with three parts, each including a vehicle-mounted DSRC communication unit, a vehicle-mounted sensing unit, and a vehicle-mounted control unit, which cooperate with each other to realize the two functions of traffic instruction information notification and traffic violation information reporting. Of course, in practical applications, the vehicle-mounted DSRC communication unit can also use other functional units with wireless communication capabilities, for example, the current 4G (ie, LTE network provided by operators) wireless transmission module with strong real-time transmission capabilities, of course, the corresponding , the RSU also needs to be equipped with a 4G wireless function module, and the RSU performs information exchange with the vehicle through the operator.

For ease of understanding, please also refer to FIG. 6 (FIG. 6 is a schematic diagram of information exchange between the RSU and the vehicle according to a preferred embodiment of the present invention).

For the acquisition process of traffic instruction information:

Roadside facilities such as RSUs are pre-built with DSRC wireless communication units. Normally, they can support information exchange with vehicles that are also equipped with wireless communication units within a radius of 1 kilometer. In practical applications, the communication radius of RSU It can be expanded or reduced by adjusting the wireless transmission power of the RSU, that is to say, the communication radius of the RSU can be adjusted according to the actual traffic management needs within the range of its own transmission power. Moreover, with the continuous development of computer hardware, RSU can also have powerful data computing capabilities and data storage capabilities, which will provide more convenience for the application of intelligent transportation. Therefore, for many traffic signs installed in the current road section, only one RSU roadside unit may be required to pre-store the traffic instruction information expressed by the traffic signs.

For example, in this preferred embodiment, the RSU can preset the traffic indication information of all traffic sign boards within a certain range by means of configuration files, and the specific information format of the traffic indication information can adopt the following expression: In(T,C ,L _b ,L _e ), where T means the type of traffic signs, including seven major categories of main signs and auxiliary signs stipulated in traffic rules, namely: warning signs, prohibition signs, instruction signs, guide signs, tourism Area signs, road construction safety signs and speed limit signs, the meaning of C is the content of the traffic sign, that is, the specific meaning represented by the corresponding traffic sign type, and L indicates the effective indication range of the traffic indication information, that is, the area covered by the traffic sign Road range, L _b and _Le denote the start position and end position of the range, respectively.

Among them, for the design of the algorithm, the traffic sign type and the content of the traffic sign are given by enumeration, and the effective indication range can be represented by a double-precision floating-point integer. If the total number of traffic signs contained in the RSU is N, then all the traffic signs The set will consist of the following formulas:

For example, the total number N of traffic signs pre-stored by the RSU is 2, which are respectively prohibiting honking and road speed limit of 15 kilometers per hour.

In order to help the driver understand the traffic indication information of the road in a timely manner, the RSU can periodically broadcast the traffic sign set S (for example, when the traffic flow is relatively small, it can be set to play the traffic indication information 10 times per second, when When the traffic flow is relatively large, it can be set to play the traffic indication information 15 times per second), and every vehicle that enters the coverage area of the RSU (with the RSU as the center and within the road range with R as the radius) will The vehicle-mounted DSRC communication unit receives the data packet (including traffic instruction information) broadcast by the RSU, the vehicle-mounted communication unit analyzes the data packet, and transmits the analyzed traffic instruction information corresponding to the current road section to the vehicle-mounted control unit. The on-board control unit judges whether the position of the vehicle belongs to the range (L _b , L _e ) of the effective indication range L of the traffic indication information, and if it belongs to this range, the traffic indication information is interpreted through the on-board voice conversion system, And make voice broadcast to the driver, and at the same time automatically activate the vehicle traffic violation monitoring and automatic reporting process of traffic violation information. If the position information of the vehicle does not belong to the range (L _b , _Le ) of the valid indication range L of the traffic indication information, the vehicle control unit will discard the traffic indication information without prompting the driver. Through this method, the driver can understand the driving rules of the road ahead at the first time, so as to avoid traffic violations or even traffic accidents caused by not finding traffic signs.

For the automatic reporting process of traffic violation information of vehicles:

When the vehicle travels to the road section covered by the RSU, the driver can keep abreast of the traffic instruction information in the road section. Most drivers will follow the instructions of the traffic instruction information and follow the traffic rules. However, some drivers have bad driving habits, or There may be traffic violations intentionally done in disregard of traffic instructions, for example, deliberate honking on road sections where honking is prohibited. At the same time, due to the lack of traffic supervision methods, some drivers may have a fluke mentality and blindly pursue the convenience of their own operation, resulting in traffic violations such as speeding, illegal U-turns or illegal parking.

In order to monitor these traffic violations in a timely manner, this preferred embodiment adopts the intelligent perception technology of the Internet of Things, and realizes automatic discovery and reporting of traffic violations by adding various types of on-board sensors, so as to help the urban intelligent transportation system realize traffic violation information. The purpose of distributed collection and acquisition.

Please refer to Figure 5. The on-board sensing unit shown in Figure 5 includes a steering wheel pressing sensor (which can monitor the behavior of honking the horn), GPS (which can monitor the occupation of non-motorized vehicle lanes, illegal U-turns, etc.), and a speed sensor (which can monitor speeding, etc.) and other sensors, and the sensor is connected to the control unit in the vehicle. Since there are many types of sensors, this preferred embodiment will use honking as an example to describe how to collect and monitor whether the traffic violation behavior of honking occurs in a vehicle. , and generate traffic violation information and report it to the intelligent traffic management platform shown in Figure 5. The principles of detection and reporting of other traffic violations are similar.

Please refer to Fig. 7 (Fig. 7 is the flow chart of reporting traffic violation information of honking the horn according to a preferred embodiment of the present invention), as shown in Fig. 7, the process includes:

Step S702, when the driver performs the action of honking the horn, the sensor will be triggered and automatically record the event, and send the event record information to the vehicle control unit.

Step S704, the on-board control unit obtains the current time and the location of the vehicle through the system clock and GPS, and judges whether the current vehicle is within the traffic control area where honking is prohibited according to the sign information broadcast by the RSU.

Step S706, if the honking event triggered by the driver is within the prohibition range of the sign board, the on-board control unit will encapsulate the above-mentioned traffic violation information into a data packet, and then broadcast it to the RSU to realize the reporting of the traffic violation information. Corresponding records shall be kept for subsequent verification by the traffic management department.

In step S708, the RSU collects traffic violation information reported by all vehicles within its communication range, and reports the results to the intelligent traffic management platform after proper data fusion processing (mainly deleting redundant data in the data).

In step S710, the intelligent traffic management platform formulates corresponding punishment measures according to traffic laws and regulations according to the processed traffic violation information.

During this process, the on-board control unit can monitor the driver's behavior and the current state of the vehicle in real time. If the control unit detects that the vehicle has driven out of the range indicated by the sign, it will terminate the monitoring process of automatic reporting of vehicle violation information, and will not report meaninglessly.

Compared with the sound method to detect whether the driver is honking the horn in violation of regulations, which is difficult and likely to cause misjudgment, this preferred embodiment uses a pressure sensor to realize intelligent detection, which has a simple implementation process and high detection accuracy.

For the remote control of the RSU by the intelligent traffic management platform:

In this preferred embodiment, the RSU can support intercommunication with the intelligent traffic management platform through wired or wireless means, and the intelligent traffic management platform can remotely control the RSU, and the control content includes: (1) the intelligent traffic management platform can remotely adjust The wireless communication parameters of the RSU mainly include communication radius and broadcast frequency. By remotely setting the wireless transmission power value and broadcast cycle value of the RSU, the traffic management department can dynamically adjust the communication capability of the RSU according to the current traffic flow, traffic conditions, road conditions and other information, realize real-time optimization of communication efficiency, and improve wireless channels Improve the quality and reception rate of data packets, reduce transmission delay, and enable vehicles to obtain relevant traffic instruction information in a more timely manner. (2) The intelligent traffic management platform can remotely adjust the type, quantity and content of the traffic signs stored in the RSU. This adjustment method will make the traffic operation extremely flexible. When there are special circumstances such as road congestion or traffic control , The intelligent traffic management platform can realize the dynamic conversion of traffic regulations through remote control, reduce traffic management costs, and improve management efficiency.

It can be seen that through this preferred embodiment, for a traffic management system that includes three types of entities, the intelligent traffic management platform, the RSU and the vehicle, the information transmission between the RSU and the vehicle can be realized through DSRC wireless communication, and the RSU and the intelligent traffic management platform The communication between them can be realized through wireless network or wired network.

Moreover, the RSU can use the DSRC wireless communication method to periodically broadcast to the vehicle to help the driver better understand the traffic indication information in the current road section, and prevent the driver from being distracted due to inattention or bad weather. Potentially dangerous situations where the line of sight is obstructed and traffic information cannot be obtained in time.

Furthermore, the detection of the driver's behavior is realized through various built-in sensors in the vehicle. When the driver is detected to have traffic violations such as honking the horn in violation of regulations, speeding, parking in violation of regulations, and making U-turns in violation of regulations, the on-board control unit can combine the current time and vehicle The location reports traffic violation information to RSU through DSRC wireless communication, avoiding the defects caused by traditional camera or manual detection methods, and can also automatically save the reported traffic violation information locally, which is convenient for subsequent verification by traffic management departments. The RSU can carry out data fusion processing on the violation information collected within its communication range, and regularly report to the intelligent traffic management platform, and the platform will carry out corresponding punishments.

Since the intelligent traffic management platform can remotely control the RSU, including the setting of wireless communication parameters and traffic indication information, it is very beneficial for the traffic management department to control the RSU according to road traffic conditions and special conditions (such as: traffic control or road construction, etc.) Traffic rules are dynamically adjusted to optimize the efficiency of traffic management.

In the embodiment of the present invention, the linkage between the vehicle and the intelligent transportation system can be realized through technologies such as DSRC, the traffic indication information pre-stored in the RSU can be obtained in time, and prompts or early warnings can be issued to the vehicle driver in time, and various sensors built in the vehicle can Realize the detection of vehicle driving status with GPS, etc., realize the linkage between the sensor and the vehicle control system, complete the automatic collection and reporting of the traffic violation information of the vehicle driver, and save the reported traffic violation information in the control system, which is convenient for the follow-up traffic management department Finally, the intelligent traffic management platform will conduct a comprehensive analysis based on the traffic violation information reported by the RSU, and give corresponding measures according to the driver's violations.

The above description is a preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also It should be considered as included within the protection scope of the present invention.
