Study On Electromechanical System Of Expressway And Its Design Plan

With the development of society, the growing national economy, people's demand in traffic has a significant increase. The design and construction of transport facilities has an impact on regional economic development and people's quality of life of key projects. Expressway as an advanced transport facilities with rapid development faces enormous challenges. How to intelligent highway to its full speed, economy, safety, comfort features, is the key issues of highway design and construction and management.At present, expressway intelligence is mainly reflected in intelligent design and management of electromechanical system. Based on described the development of expressway and electromechanical system, This paper analysis of the structure and function of electromechanical system, and study more in-depth on the structure, function, equipment component and main technical conditions of subsystems of expressway electromechanical system.First, this paper analyzes the characteristics of traffic flow and the relationship among parameters of expressway traffic flow. Based on discusses traffic flow models and various interference factors of traffic flow, this paper then describes several control methods of expressway; and in-depth study composition, structure and function, etc of expressway electromechanical system. Combines the situation of Xin-Jin expressway Kuai-ying to Yingpan section, this paper predict of the section traffic volume and analysis the section traffic flow characteristics; and analyzes major and difficult issues exist in design and construction of the electromechanical system. Finally, drawing on the existing advanced control and management methods of expressway electromechanical systems, this paper designs and instructions the electromechanical system of Kuai-ying to Yingpan section of Xin-Jin expressway.
