The most basic and important components of the construction of "Safe City" and "Intelligent Transportation" are the front-end video monitoring system, the transmission network, and the back-end intelligent analysis platform. The integration of the two is conducive to interconnection, saving construction costs and construction cycles. It is of great significance to improve the level of urban visual management and government emergency response capabilities, and maintain urban public safety and order. Next, we will describe the solution of smart cities through the integration of Ping An City and intelligent transportation, demonstrating the integration of intelligent transportation management systems, social resources, and public security information networks.



1. Ping An City
(1) Through data sharing, analysis, mining, and judgment, the construction of a safe city realizes the digitization and intelligence of public security operations, improves the ability of public security organs to "fight, prevent, control, manage, and serve society", achieves the goal of unified command, timely response, and effective combat, strengthens city level security prevention capabilities, squeezes crime time and space, and achieves effective management of the city.

(2) The architecture system of Ping An City consists of five levels: monitoring resources, transmission networks, shared platforms, monitoring centers, and management applications. Video resource layer: transmission network; Shared platform; Monitoring center; Manage the application layer.

(3) The Ping An City Platform Software Management Platform System is the superstructure of Ping An City and the core of its application layer. If video capture and encoding and decoding technology are likened to the eyes of Ping An City, then platform software is the brain of Ping An City. The Ping An City platform software is divided into operation and maintenance management platform, network sharing platform, and intelligent practical platform. The intelligent practical platform concentrates the most important functions of Ping An City and has the highest requirements.

(4) The dense deployment of monitoring points in the Ping An City intelligent video analysis system weaves into the city's security and prevention network, but the huge amount of information can also bring new problems. For example, when facing dozens or even hundreds of TV walls, monitoring personnel often easily distract their attention, and cannot be prepared to detect and handle sudden intrusions and abnormal suspicious events, which increases the difficulty of post investigation investigation of cases. The intelligent video analysis system introduces functions such as intelligent behavior analysis perimeter prevention, intelligent facial capture comparison, and intelligent video quality diagnosis.

(5) The advantages of Ping An City's wireless monitoring system based on wireless networks include high low cost, flexibility, convenience, and protection of existing infrastructure layout. Therefore, wireless monitoring applications are particularly suitable for implementation in areas such as rivers, forests, and tourist attractions, as well as management and monitoring of individual soldier terminals and vehicles. With the reduction of wireless communication and transmission costs, diversification of methods, and improvement of security performance, wireless monitoring systems are becoming an important component of the layout of safe cities.




2. Intelligent transportation
The introduction of the concept of intelligent transportation provides new ideas for solving problems such as traffic congestion and driving safety. Intelligent transportation introduces new technologies represented by the Internet of Things and cloud computing, establishing a comprehensive transportation system with a larger spatial and temporal range to improve the operational efficiency of urban transportation, reduce traffic accidents, reduce environmental pollution, and enhance the level of informatization, intelligence, socialization, and humanization of traffic management and travel services.

(1) Traffic information collection system
The traffic information collection system consists of three parts: front-end detection equipment, communication equipment, and command center management system. Advanced traffic information collection systems can grasp the current traffic operation status and predict future traffic conditions, greatly improving traffic efficiency and achieving intensive development of transportation. The traffic flow detection system utilizes technologies such as microwave, coil, and video detection to detect basic traffic flow information such as traffic flow, occupancy rate, speed, and vehicle type on the current road section. It obtains real-time traffic flow conditions on each monitored road section, determines the occurrence of traffic congestion, and timely provides it to the traffic management department for adjustment through corresponding diversion guidance, information prompts, and other means.

(2) Traffic guidance system
The traffic guidance system consists of outdoor display screens, command center control systems, communication systems, and other components. Focusing on key sections such as urban main roads, LED guidance display boards will be set up to reuse traffic data collected by electronic police and checkpoints. After processing by the traffic management comprehensive application platform, guidance information will be generated for public release, which will be automatically generated or manually confirmed before release.

(3) Intelligent Traffic Management Platform
The intelligent traffic management platform is a unified information platform that serves the urban traffic command system, achieving information exchange and sharing, rapid response decision-making, and unified dispatch and command. By analyzing and processing the collected static and dynamic data, implementing traffic management control and guidance, timely handling traffic events, and publishing traffic information to traffic participants through various channels. Following the requirements of the "Technical Specification for the Construction of Public Security Traffic Command System" (GA/T445-2010), the integrated platform is divided into functions based on different business needs, forming a command and dispatch platform with the integrated command platform as the core and related functions such as road condition monitoring, traffic signal control, investigation and control, information service, and business management as components, namely a command and dispatch platform and five business application systems.
