IoT adds strength to intelligent transportation to help the Olympics

In July 2012, the opening of the London Olympics was imminent, and all walks of life paid great attention to this event. However, British Prime Minister Cameron said recently that although he is ready to meet this event, traffic problems are still a big problem for them. Earlier, London has invested billions of pounds to improve the transportation system, but a recent special evaluation report, London's transportation network is currently in a state of nearly full operation. It can be said that the traffic problem will be the "biggest worry" facing the 2012 London Olympics.

The traffic situation at the London Olympics has filled the world with conjecture. How did the Beijing Olympics in China four years ago solve the same problem?

During the security of the 2008 Beijing Olympic Games, the country put forward the concept of "technical Olympics" and used intelligent transportation as a strong support for Olympic security. In order to realize the purpose of "Humanistic Olympics, High-tech Olympics and Green Olympics", and to guarantee the traffic order outside the Olympic venues, the state takes the modern public security traffic command center as the leader and comprehensively integrates the intelligent traffic technology system. Among them, the "Internet of Things Intelligent Traffic Signal Control System" developed by Baoding Viterui Corporation is one of the important contents of intelligent transportation. Based on this system, the country has established an Olympic service and urban operation command system, which has realized the flat command and dynamic control of the venues and surrounding traffic. The Olympic central area, the periphery of the Olympic venues, the driving routes, and the fifth ring road are all realized. With the coverage of scientific and technological means of networked intelligent transportation, the overall control capacity of road traffic has been significantly improved.

The reason why the intelligent traffic signal control system of the Internet of Things has such a "supernatural power" is that it integrates advanced information technology, data communication transmission technology, electronic sensing technology, electronic control technology and computer processing technology, etc., and is used in traffic management. smart system. The system developed by Baoding Viterui Transportation Facility Company combines Internet of Things technology with green intelligent transportation, uses solar cells for power supply, uses a variety of Internet of Things transmission methods, and combines a traffic flow collection system and a traffic signal control system to achieve real-time Collect traffic flow data to provide timing basis for traffic signal control. Through the collected data, through the Internet of Things remote traffic management measurement and control center platform to "think" the collected road real-time information, so as to make overall calculations for the entire transportation system and make more changes Good scientific traffic management and control scheme.

Take the Beijing Olympics as an example. According to estimates, the Internet of Things intelligent traffic management and control system built in the Olympic central area can improve the efficiency of intersections and road sections by reasonably adjusting the transit time of vehicles, increasing the comprehensive capacity of the road network by 15% and achieving 38 venues. The three-dimensional control of social traffic and service traffic, positioning to the car, alternating release, accurate to the second, effectively guarantees the traffic safety, punctuality, reliability, convenience and social safety of more than 3000 important competitions and more than 30 important events of the Olympic Games The harmonious operation of traffic.

In fact, the Internet of Things intelligent traffic management and control system has been successfully applied by the Internet of Things traffic management and control system before the Beijing Olympics. Not only has it effectively improved the quality of Beijing ’s road traffic during the Olympics, it has also contributed to Of the affected people provided a safe and smooth traffic environment. Affected by the summer monsoon rainy season in September 2011, the heavy rain in Pakistan paralyzed Karachi, its largest city, and the city ’s traffic was completely destroyed. China provided 3000 people including the “Internet of Things Intelligent Traffic Signal Control System” to the Pakistani victims Ten thousand yuan emergency humanitarian relief materials, after the installation of the "Internet of Things Intelligent Traffic Signal Control System" in Karachi, due to its multiple power supply methods and the use of Internet of Things technology for intelligent traffic control, Karachi's urban traffic management was quickly restored The operation of the control system guarantees the normal production and life of the people.

Through the Internet of Things traffic management and control system, a variety of methods can be achieved, such as data collection and transmission, which eliminates the need to dig trenches, nets, and wiring when installing using traditional traffic control products, which affects the appearance of the city and the travel of the public. The Internet of Things intelligent traffic signal The control system is powered by solar cells, which not only consumes traditional city power, but also adopts a variety of IoT technologies such as time synchronization control system, wireless data transmission and collection system, without the need to embed pipeline lines and destroy roads, and realizes the use of IoT The control platform realizes the purpose of intelligent control of the traffic situation. The traffic control is very convenient, and the investment and maintenance costs are relatively low. For scientific relief and channeling of road traffic pressure, the improvement of road traffic service capacity and safety factor, energy saving and emission reduction have Significance.

As one of the most important application fields of the Internet of Things, traffic signal control based on the Internet of Things technology will greatly change the service mode and improve the service level in the transportation field. In the 12th Five-Year Plan, the Internet of Things and intelligent traffic management systems With its corresponding status. The traffic management and control system based on the Internet of Things technology is the development direction of modern traffic management. It uses advanced sensing technology, mobile interconnection technology, data collection system, intelligent control and intelligent computing technology to control the real-time traffic of the road, and finally achieve road traffic "Zero clogging" and "Limited capacity".
