How to solve the traffic jam problem during the National Day holiday?

At present, with the acceleration of urbanization and the popularization of automobiles, the contradiction between supply and demand of transportation in major cities has intensified, and traffic safety, traffic congestion and environmental pollution have become the three major problems that plague China's transportation field. Statistics show that the per capita road area in China is only 10.6 square meters, which is far lower than that in foreign cities 15-20 square meters. At the same time, the number of urban motor vehicles is increasing at a high speed of 15%, while the growth rate of urban roads is only about 3%. The "Eleventh" holiday has always been the peak time for people to travel. 20 13 holiday minibus free policy continues to be implemented, and self-driving travel has further become a new mode of travel. According to the forecast of relevant departments, the number of tourists will exceed 430 million during the "Eleventh" period this year, with a year-on-year increase of18%; The total highway passenger traffic increased by 6% year-on-year, with an average daily passenger traffic of 85 million passengers. According to the statistics of public security traffic management department, in the first eight months of this year, the number of small cars in China exceeded 1 1 10,000, and the number of small cars in China was 94 million. It is estimated that the number of self-driving trips during the Eleventh Five-Year Plan period will be significantly higher than in previous years.

The surge of traffic flow has increased the pressure of safe driving of road traffic. According to the statistical analysis of the Traffic Management Bureau of the Ministry of Public Security, from the situation of the "Eleventh" holiday accidents in recent five years, the road traffic accidents that caused property losses increased year by year, and the accidents involving casualties were more frequent than usual. Judging from the characteristics of the "Eleventh" holiday accidents in recent five years, firstly, the tidal traffic flow at the beginning and end of the holiday led to frequent accidents, accounting for nearly 40% of the total accidents during the holiday. Second, about 60% of accidents are caused by private cars, and the proportion is increasing year by year. Third, there are high accidents in key tourist areas and provinces around Beijing, the Yangtze River Delta and the Pearl River Delta. Fourth, the number of people killed in accidents at night accounts for 16. 1% of the total, which is 1 times higher than that at the same time every day. In the past three years, the death rate caused by the noon113 accident has increased year by year. Fifth, the proportion of road accidents in expressway and rural areas is increasing year by year, and the accidents that cause mass casualties mainly occur in expressway and rural roads. Sixth, speeding, not giving way according to regulations, and driving without a license are the main causes of accidents during festivals, while in rural areas, problems such as overcrowding of vans, mixed loading of passengers and goods, illegal manned tractors, drunk driving and driving without a license accidents are prominent. Faced with such a severe situation, how to reduce the pressure of traffic congestion and its impact on society has become a problem we must face.

Intelligent transportation is the hot spot and frontier of transportation development in the world today. Relying on the existing transportation infrastructure and vehicles, it aims to build a safe, convenient, efficient and green transportation system through the integrated application of modern information, communication and control technologies to fully meet the diversified needs of public travel and cargo transportation. It is an important symbol of modern traffic. In the face of the above problems, intelligent transportation may give us a good answer.

In foreign countries, Japan's smart road system, Europe's green intelligent transportation and America's intelligent driving strategy are all effective practices in the development of intelligent transportation. First-and second-tier cities in China have begun to use intelligent transportation systems to alleviate the traffic pressure caused by congestion. How does intelligent transportation play its role?

Intelligent Transportation System (ITS) integrates computer data processing, automatic control, information, data communication and transmission, electronic sensing and other advanced technologies and applies them to the transportation management system, thus establishing an all-round, large-scale, real-time, accurate and efficient comprehensive transportation management system.

The application of ITS mainly lies in that ETC system can reduce the time delay and manpower consumption brought by traditional toll collection mode and improve the traffic capacity of lanes. Road traffic sensors can monitor the pressure and stress of the road in real time, and transmit the monitoring data to the management center to know the road situation in real time and provide complete information for the maintenance department; Variable speed limit signs and variable information signs, real-time display of road conditions and accidents along the way, timely release of speed limit information, and dynamic management of traffic flow; Expressway on-ramp traffic flow control uses the communication with the monitoring center and the signal lights of the on-ramp to intelligently monitor the on-ramp traffic flow; Closed-circuit television monitoring, the use of closed-circuit television cameras, real-time monitoring of illegal vehicles, found that the problem can be started in time to deal with the emergency mechanism. Electronic police system, using video monitoring, speed measurement, automatic control and other technologies to achieve offline traffic violation punishment.

In road traffic management, three systems, namely, road traffic video monitoring, motor vehicle traffic violation monitoring and capture, and smart card port, are the main force, are important components of the intelligent network system for road monitoring, and play an important role in road traffic guidance management. The first is command and dispatch. In the event of traffic jam or accident, the command center can quickly retrieve the on-site information through the video monitoring system, and timely implement rescue or take corresponding measures. Therefore, video surveillance can be a powerful assistant for relevant departments to respond quickly when dealing with emergencies. The second is vehicle driving supervision. Through the video monitoring system, the driving situation of vehicles on the road can be monitored at any time, and if violations are found, photos can be taken for evidence collection. Capturing the license plate information of illegal vehicles through license plate recognition and increasing punishment can effectively stop illegal behavior. Video surveillance has played a very good role in monitoring and deterring illegal driving vehicles. The third is traffic monitoring. By monitoring the traffic flow changes of road vehicles, the command center can quickly take countermeasures to evacuate vehicles and reduce congestion. Among them, the use of video surveillance can effectively monitor the traffic conditions of urban roads, facilitate the rapid deployment of command centers, and provide a lot of effective information for the optimization of urban traffic networks.

At present, the mature applications of video surveillance products in urban road traffic mainly include: urban main roads and intersections video surveillance system, inter-city expressway video surveillance system, and vehicle-mounted video surveillance system for vehicle internal monitoring.

Among them, the monitoring system in expressway is generally divided into road monitoring, service area monitoring and toll station monitoring. Among them, the road monitoring system mainly monitors key road sections, grasps the traffic situation in expressway, finds traffic jams and illegal vehicles in time, and gives timely guidance to ensure the safety and smoothness of expressway. In addition, the inter-city expressway monitoring system should also have the functions of speed capture, bayonet vehicle identification, traffic incident detection and analysis, vehicle multi-channel identification and so on.

In expressway video surveillance system, the video surveillance intelligent management platform integrates subsystems such as management video surveillance, bayonet license plate recognition, and intelligent analysis of traffic incidents. It has a variety of information publishing methods and a large number of data statistics functions, and at the same time reserves interfaces for traffic guidance, traffic detection and other systems. Among them, expressway traffic incident intelligent analysis system generates incident alarm according to image processing algorithm, and detects abnormal traffic incidents in time, which is of great significance to further improve the management efficiency of the system and the management level of expressway.

Intelligent Transportation System (ITS) is considered as one of the effective methods to solve urban traffic problems. ITS can improve traffic efficiency and reduce traffic accidents. The idea of developing ITS makes people get rid of the traditional mode of restricting cars only by building roads, and tries to strengthen the connection between people, cars and roads with high technology to improve the efficiency of transportation system.

Changsha is planning to build an intelligent traffic guidance system. Intelligent traffic guidance system consists of three parts: dynamic traffic information collection subsystem, data fusion and processing platform subsystem and traffic guidance information release subsystem. The main working principle is to collect dynamic traffic information through the road dynamic traffic information collection subsystem, and gather it into the traffic management command center for comprehensive processing, and then release the processed guidance information to the traffic guidance terminal through the traffic guidance information release subsystem to inform the motor vehicle driver of the road traffic situation ahead in advance. The basic idea is to use video surveillance, taxi, bus GPS positioning and coil detection to collect traffic guidance information. It is planned to use the embedded graphic display screen of light bar and the combined display screen of embedded graphic of light bar and +LED plate to release traffic guidance information. It is planned to build 50 driving guidance display screens at major intersections and road sections in urban areas.

20 13 Beijing traffic management bureau is studying the trial installation of electronic license plates, and a unified electronic license plate standard may be issued by the end of 20 14. Electronic license plate can realize accurate real-time positioning of vehicles in meters and seconds, and can finely manage every time of each road. At the same time, it can provide convenient technical means for discipline inspection and supervision departments to supervise buses, public security departments to trace stolen vehicles, traffic control departments to check speeding, running red lights and other violations, and management departments to collect parking fees.

The electronic license plate is about the size of the credit card we usually use. It can store basic information of vehicles such as license plate number, model and color. It is installed on the windshield of the car. When a car passes through a base station consisting of a microwave reader, an antenna and a computer, it can automatically report the information on the electronic license plate within a few meters without stopping.

Intelligent transportation system can certainly bring light to traffic congestion, but the construction also needs reasonable planning. The intelligent transportation system in expressway is a huge comprehensive system engineering that integrates administrative management and technical management across departments and fields. Only by carefully planning development and defining the future development direction, work objectives and implementation steps can we save costs, avoid detours and achieve the expected results. Expressway Intelligent Transportation System is a comprehensive application system of information, communication, network, automatic control, traffic engineering and other technologies. Only by building infrastructure such as communication lines, flow sensors, vehicle sensors and traffic safety facilities in advance can the relevant departments provide a good foundation for the development and improvement of the system in the future.

With the development of intelligent transportation and the continuous improvement of various supporting systems, a series of problems such as urban road congestion and low speed in expressway will be completely solved, and we can really enjoy the benefits brought by national preferential policies.
