Special applications under the background of the h

At present, traffic congestion and traffic accidents are common problems faced by global urban road traffic. Due to the limited land and space available for road construction, it is difficult to solve the main traffic problems faced by the city by building new roads alone. On the other hand, the increasing traffic demand and the increasing complexity of the transportation system make it difficult to effectively solve the problems of traffic congestion and environmental pollution only from the perspective of vehicles or roads. How to apply modern high-tech to connect vehicles and roads to solve traffic problems systematically has become the core idea of intelligent transportation. Through the effective integration and application of advanced intelligent monitoring technology, communication technology, control technology, sensor technology and system integration technology in the field of transportation, intelligent transportation has made fundamental changes in the transportation industry: intelligent operation function and maximization of efficiency, thus making it a hot spot in the research, development and technology application of the same industry in the world

analysis of the application background of intelligent transportation

in 2014, road congestion, as one of the most criticized "urban diseases" in large and medium-sized cities in China, became increasingly prominent. On the huge road traffic, how to deal with the traffic jam caused by traffic accidents or accidents, how to make the signal system at the intersection smart, and the road traffic shuttling between cities is changing, so intelligent transportation appears. It is the development direction of the future transportation system, and its goal is to establish an all-round, real-time, accurate and efficient comprehensive transportation system of 6) orthoclase 7) quartz 8) Topaz 9) corundum 10) diamond, so as to "ensure safety, improve efficiency, improve the environment and save energy". That is, on the basis of relatively perfect road facilities, integrate advanced transportation theory and high-tech into the whole process of road transportation, strengthen the connection between vehicles, roads and people, collect and analyze traffic data intelligently, and feed back to the operator or driver of the system. With the help of the processed traffic information, the system operator or driver can quickly respond and improve the traffic conditions. Intelligent transportation emphasizes systematization, real-time, interaction of information exchange and universality of services, which is essentially different from the original traffic management and engineering

intelligent transportation has its special application background, which can be said to be the product of market demand

rapid economic development has led to the deterioration of traffic conditions and the environment

China has experienced more than 30 years of rapid development of reform and opening up, and urbanization and motorization have developed very rapidly. The urbanization process has further strained urban transportation resources. It is expected that China's urbanization will rise from the current 45% to 60% in the next decade, which will further promote the development of transportation and automobile industries. However, urban transportation resources will be more tense. The number of motor vehicles has increased by more than 10% every year. This year, the number of motor vehicles in China is 253million. In the past two years, Beijing has challenged the carrying capacity of roads with the speed of adding 10000 vehicles a week. The air quality in Chinese cities continues to deteriorate, and vehicle exhaust has become a major source of pollution. In some big cities, the contribution rate of vehicle emissions to a number of air pollution indicators has reached more than 60%, which is seriously endangering people's health. Traffic congestion, speed decline, poor vehicle condition and low technical performance of vehicles make China among the top ten cities with the most serious air pollution in the world. The bottleneck of traffic development has become an important factor restricting China's urban development; In terms of road management, due to the regional restrictions of administration and investment, regardless of whether the machine is often used or not, China's highway management and ordinary highway management have formed a management mode based on administrative regions and sections, and there is no unified resource management system proposed in terms of infrastructure; In terms of vehicle management, a unified vehicle management system has not been established. Most of the transportation informatization construction systems in China are only built to solve some specific and local problems, so each system basically exists independently, presenting an information island mode under the network background

improve the layout of the traffic environment video monitoring "Da Lian"

in order to improve the intelligent transportation information island phenomenon, the Ministry of public security plans and deploys to realize the video image joint scheduling and resource sharing of the national public security organs by 2015. This shows that video surveillance "Da Lian" is an inevitable trend. This also brings good news to the intelligent transportation system. To a certain extent, the implementation of the intelligent transportation monitoring system "Grand Alliance" makes full use of video monitoring resources, avoids the information island caused by the video monitoring system, improves the comprehensive utilization of resources, and plays an irreplaceable role in joint charging, emergency rescue, command and scheduling, etc. In terms of tracking vehicles for some major events, cross provincial or cross city highway monitoring wastes a lot of human and material resources on the time node of suspected vehicle monitoring. For example, the realization of the national highway monitoring "union" can greatly improve the police case handling efficiency, break the local resource restrictions, and truly realize resource sharing

the monitoring system resources should also avoid the waste of resources in different departments, and realize horizontal sharing of transportation, public security, urban management and other information. For example, at the same monitoring point, the public security surveillance camera of the public security department, the road surveillance camera of the traffic police department checking and compensating the online revision load summation table, and the urban management surveillance camera of the urban management department may appear at the same time. In some cases, the cameras and even the monitoring range of different departments are the same. Such construction is a waste of human resources, equipment and funds. One of the main reasons leading to this kind of repeated construction is the lack of unified planning without connection, which makes it impossible to form a unified management from bottom to top. All departments are independent systems, and cannot carry out effective coordination and cooperation. This construction method only pays attention to vertical development and ignores horizontal cooperation, which greatly reduces the monitoring effect. The traffic monitoring union is conducive to breaking this restriction of segmentation, and finally forming a coordinated and unified system with one person building, many people using, one point triggering and multi-point linkage

bus parking management based on IOT

in fact, since the construction of bus stop parking management based on IOT, the problem of urban traffic congestion has become increasingly serious, and the development strategy of "bus priority" is being promoted all over the country. At the same time, the access of vehicles and personnel in the bus parking lot is complex, and the safety management of the station has become a major problem for the public transport supervisors, so the measurement will not be accurate. Applying IOT technology to the safety production management of bus parking lots and stations effectively solves the related problems of vehicle access supervision, realizes the digital and intelligent transformation of bus parking lots and stations, and improves the management level and work efficiency of the industry

the safety supervision system of bus parking lot based on IOT technology is mainly composed of two parts: vehicle access management system and intelligent video monitoring system of the station. Using advanced "IOT technology", the user end is extended and extended to bus vehicles and any items in discontinued stations for data exchange and communication, so as to comprehensively and stereoscopically solve the supervision problems of the bus industry
