With the rapid development of computer technology, network technology, information technology as a driving and implementation management system innovation, technology innovation, management innovation, an important means to strengthen the key competitiveness of management unit and the only way. So make full use of modern computer technology, to research developed a corresponding computer management system and it can convenient, accurate and fast provide scientific means for maintenance engineering budget. So it will help to improve the level of maintenance management. In this paper, a highway cost management system based on Client/Server design is studied and discusses the application of this system in the present advantages and technical development methods.
