In recent years, ITS rapid development in the global scope, all kinds of intelligent technology has become increasingly widespread In the expressway. As in the mountainous area highway roads construction is more and more, the proportion of the tunnel are more and more. Tunnel construction project, the increase of tunnel monitoring system design more and more is also high. As is known to all, highway tunnel is the key part of the safety control in highway tunnel, the damage will be bigger, processing, the time will be longer interrupt driving. Therefore, decrease and prevent traffic accidents in tunnel will become especially important. Tunnel monitoring equipment and perfect the accurate control of the system function is adapt to the needs of its outstanding, plays a role, is to prevent accidents or reduce accidents rank, shorten the driving interrupt time among the most effective ways.In this paper, based on the Guangdong and Hunan expressway Boluo to Shenzhen projects for long tunnel construction of Shigu intelligent transportation system, the design method of the intelligent monitoring system and development trend are discussed, and the system software functions need to achieve the objectives are analyzed and studied.Based on actual operating conditions of Shigu prediction of the tunnel, the tunnel traffic control summarized the general rules of operation for the normal, periodic traffic congestion and failure blocking abnormal control strategy proposed by three states to address the abnormal state, the target vehicle lane and blocked traffic conflict problems; Shigu by analyzing the actual needs of the lighting inside the tunnel, the specific operating environment of tunnel, statistics, analysis the tunnel lighting control system, according to light intensity detector data, respectively, to achieve manual control of the tunnel lighting, sub-timing control and automatic control, to solve different climate, time, tunnel lighting under control, and lighting for the comparative analysis of financial technology to reduce operating costs the tunnel; Shigu tunnel ventilation scheme with technical and economic comparison analysis, and tunnel ventilation control Facilities CO and visibility (VI) detector and the wind (WS) detectors and other equipment to set Scheme, proposed for the ventilation control Shigu program and control.
