This text was introduced the specific property of highway traffic mechanical and electronic engineering and the contents of inspected and control working, according to the practice of inspected and control work of expressway mechanical and electronic engineering , putting forward some thinkings to strengthening inspecting and control work to the mechanical and electronic engineering.

Applications of FEM to mechatronics engineering;

With the fast development of the highway traffic construction course in China and the continuous enhancement of the highway modernizing management level, the electromechanical engineering is playing the important role in the construction of the highway traffic.

The establishment of the competitive bidding mechanism has brought the hope and opportunities for the traffic and electromechanical engineering construction enterprises,apart from the strength of the enterprise,the skills of bidding have a vital effect on whether the enterprise could get the bid and earn more profit in the market competition.

In light of the construction supervision conditions of traffic and electromechanical engineering for Yizhou - Liuzhou Express Highway, this paper introduces the preparations, three control points, the approaches and measures for the administration of contract, information and safe production in the construction supervision of traffic and electromechanical engineering.
