Development Of Highway Monitoring And Management System Based On Flex

As the main part of highway traffic,the traffic density of expressway is increasing year by year.In addition,the vehicle driving speed is generally faster,the climate along the highway is complex and changeable,and other factors,the overall operating condition of expressway changes rapidly.Therefore,the operation management organization puts forward higher requirements on the realtime performance of the monitoring system.There are a large number of equipment installed along the highway,especially in the tunnel,which generates a large amount of data.The user interaction fluency of the monitoring system becomes the bottleneck of the system.The highway operation adjustment and overall planning cannot be separated from the support of data analysis.In the face of the above situation,the traditional system based on Web technology has gradually failed to meet the demand,which has generated the need to apply rich network application technology to solve the problem of expressway monitoring and management.Flex is a kind of rich Internet application technology.In this paper,Flex and its architecture technology are adopted to build a centralized expressway monitoring system,so as to realize a highway monitoring system with high real-time performance,efficient statistical analysis,good interactive experience and rich statistical output,so as to meet the needs of operation management organizations.The main work of this paper includes:(1)System requirement analysis.Analyze system requirements in detail according to application scenarios and requirements documents,establish requirements analysis model,and conduct business modeling of roles according to the personnel organizational structure.(2)System design.The system is designed from four aspects of overall structure,functional structure,logical structure and network structure,and the main functions of the system are designed according to the functional structure division.The advantages of applying Flex technology in system design are pointed out.(3)System implementation.This paper studies the business implementation logic of the system from two aspects of view layer and control layer,selects some main functions to study,analyzes them from the aspect of implementation logic,and gives the implementation effect of key functions.(4)System deployment and test.This paper introduces the deployment environment of the system,and tests the system from functional and nonfunctional aspects.The test and application results of the system show that the centralized expressway monitoring system developed by Flex and its architecture technology has the capability of real-time and efficient data statistics and analysis,helping users to timely understand the operation status of the expressway and make operational adjustments.The system has the rich statistical report output function,for the user omni-directional multi-angle knowledge highway operation condition to enhance the powerful support.The system has the rich statistical report output function,for the user omni-directional multi-angle knowledge highway operation condition to enhance the powerful support.The system has rich interface design and smooth user interaction process to help users easily complete the complex work tasks.On the whole,the system solves the difficult problem of monitoring and management faced by the highway operation management agency.
