Investigation object including traffic policemen, traffic manager member is students safety management personnel, education
18、 department personnel, etc. Through the investigation as can be seen, the present basic unit for traffic safety education video audio teach product. There is a great demand, but because of the traffic propaganda education personnel computer level is generally low, the existing commercial video audio
19、 editing software learning time is spent long and operation is more complex, difficult to promote the use of; But mission staff to grasp a lot of graphic material, provide the advertising company, film and TV making company the cost is high, mission of teaching personnel made little taste autonomy,
20、contents to update efficiency high; At the same time mission personnel need convenient and effective way of management hand collection amount of material, can best video and audio editing the effective combination of the software function. According to the research content and analysis, the traffic
21、mission personnel need to quickly into to teach product manufacture software of publicity, can save the publicity materials production room and cost, rich education means, but the grassroots no such technology, software and material database. Traffic mission and researchers to traffic 6safety video
22、audio editing the function of the software needs and framework description as follows: 1) like cameras easy to use; 2) operation steps in the s to IO step inside can complete a depending on the operation of the product audio frequency teaching; 3) has the rich material database for the unity of the
23、material management and storage. The existing commercial video audio editing software and cant completely to adapt to the needs of the traffic security education. Traffic safety education special system should have general video audio editing system of general function and apply to the traffic secur

25、ideo audio editing system. 3 The system framework and function module design In order to satisfy the users convenient is application and the actual demand, and maintain the system architecture of the linear and simplicity. The main functions of each part of the system are as follows: 3.1 Management
26、module 7In order to facilitate the management and the users of the audio editing video processing use, according to the traffic safety education material data source the characteristics of large, widely, design a special access and management module, such as video, audio add classification according
27、 to the information and classification and the key word to search references. The traffic security education number according to the design of the model is to be realized the whole video audio editing system basis and data source. 3.2 Piece of degree analysis work together Use of traffic safety educ
28、ation data storage and management model can be a large number of days often street surveillance video, to extract useful to mission of illegal traffic line for, usually the way is by artificial watch splicing manual processing, is neither and cant easily when to ensure that no gaps. The system analy
