Intelligent public transport is to use the most advanced GPS positioning technology, 3G communication technology, GIS geographic information system technology, combined with the operating characteristics of public transport vehicles, to build a bus intelligent dispatch center, to plan and dispatch lines and vehicles, to achieve intelligent scheduling, improve public transport The utilization rate of vehicles and the monitoring and management of buses, stations and stations are realized through the construction of a complete video surveillance system. Analysis of intelligent public transportation security technology In recent years, the United States in the management of public transport fleet, with the vehicle, improve service (supply) efficiency and quality and passenger safety as the core, actively absorb various vehicle-based APTS technology and new concepts of vehicle and fleet dispatch operations, improve the public The effectiveness and reliability of the traffic makes the bus approach more attractive to potential passengers and service areas. Positioning technology: Vehicle automatic positioning system is one of the core technologies of intelligent public transportation system information construction. The Automatic Vehicle Positioning (AVL) system (sometimes referred to as the vehicle automatic monitoring system or the vehicle automatic positioning control system) is widely used in the positioning of various civil and military vehicles such as public passenger transport, freight transport, police cars and ambulances. With control. With the continuous promotion of AVL applications, it has brought considerable benefits to various departments. The vehicle automatic positioning system monitors the real-time position of each vehicle and transmits the information to the control center. In this process, different monitoring and information transfer technologies are used depending on the needs of the bus system and the choice of technology, including (possibly using one or multiple technologies at the same time): land-based radio technology, road sign technology, mileage Table technology and Global Positioning System (GPS), etc. Geographic Information: Geographic Information System (GIS) is a special computer data management system. In recent years, GIS has become more and more widely used in public transportation. The most common applications are in urban bus route management, dispatch management and corresponding information, transmission, etc. In addition, it is also used in the field of route service quality evaluation, line adjustment optimization and route planning. As the availability of (public or private) data continues to increase, GIS will become more widely used in public transportation. Undoubtedly, when the computing technology and communication capabilities are further improved and the spatial data obtained is more accurate, the application and influence of GIS in the public transportation system will be more extensive and profound, especially for special transportation modes and special transportation needs. Area. Passenger automatic counting system: The passenger automatic counting (APC) system is an effective way to automatically collect passengers' time and location data. The basic components of the passenger automatic counting system are: passenger counting method, positioning technology and data management system. The most common types of counting systems are pedal inductive and infrared. APC data can be applied to real-time and post-management work of public transportation systems, such as assisting in making reasonable departure plans, real-time passenger information systems, nationwide bus operation data statistics reports, scheduling planning, site planning, fleet management plans, etc. . It is foreseeable that in the near future, the APC system will play more roles. Through this system, data collection costs can be reduced, more diverse and wider data can be obtained, and processing time of geographic data information can be reduced. Reasonable operating plan to improve operational efficiency. Bus operation software system: Through the bus operation software system, it can realize the automation, pipeline and integrated operation of various bus modes and various bus transportation functions. The application of computers in operations management, such as computer-aided dispatching service monitoring, management control and data collection (and APTS technology for providing data), can make operations scheduling, line planning, passenger service and other departments more efficient and play a bigger role. The role. Traffic signal priority system: The traffic signal priority control system turns the traffic signal (advance) into a green light when the bus passes through the intersection, thereby allowing the vehicle to pass through the intersection faster. This technique has long been used for signal priority control of ambulances. In the bus priority technology, the bus or rail transit is prioritized at the signalized intersection to ensure the punctuality of its dispatch operation. Smart bus and car video applications First, video passenger flow statistics technology Bus companies have an urgent need for passenger flow statistics, and especially want to know the passenger flow data of each line and site. The traditional bus passenger flow statistics adopts the pedal mode or the infrared radiation mode. The accuracy of these two acquisition modes is low, and the passengers can not make a correct judgment on boarding and disembarking. The accuracy of video traffic statistics is significantly higher than the traditional method, and it can be judged whether to get on or off according to the personnel movement mode. The relevant intelligent application can be realized on the public transport machine in the future. Second, face recognition comparison technology As a public place for public transportation, public transportation vehicles have a very large daily traffic. If you can upload the daily passenger's face image to the monitoring center and compare it, you can find the wanted criminals or thieves in a fugitive situation in time. Criminal cases can provide pictures of suspects. Third, high-definition camera access technology The public transport integrated machine can realize high-definition digital camera access, and more clear materials can be collected through the high-definition camera. For example, the vehicles occupying the bus lane can be photographed and compared, and the illegal vehicle license plate can be reported. Fourth, car networking applications The vehicle networking system refers to the use of advanced sensing technology, network technology, computing technology, control technology, and intelligent technology to comprehensively perceive vehicle conditions and road traffic, and realize the interaction of large-scale and large-capacity data among multiple systems. Monitoring and management of roads and roads to improve traffic efficiency and traffic safety. As one of the core equipments for the intercommunication between the vehicle and the central platform, the public transport integrated machine will realize the application of the related technologies of the vehicle networking in the future, such as reporting road congestion information, passenger detention information, and obtaining vehicle guidance information. Through the vehicle networking related technology, the real-time intelligent bus dispatch management of the vehicle can be performed through the road condition information. And with the promotion of 4G technology, passengers can use the WIFI network and 4G network of the integrated machine to access the Internet while riding. Provide remote platform behavior specification monitoring, real-time query of remote vehicle status, and remote platform fault alarm and diagnosis and other central platform functions.
