Establishment of Construction Safety Early-Warning System for Mountainous Freeways

In recent years, with the rapid development of the national economy, frequent construction accidents on mountainous freeways result in a great loss of national property and become the focus of the nation’s attention. It is urgent that we establish a construction safety early-warning system for freeways in mountainous regions in order to radically improve the situation of safety management. Major hazard identification and risk assessment is still lacking in the field. In order to solve this problem, a construction safety early-warning system for mountainous freeways was established. The targets, function, input and output of system were analyzed. The safety early-warning indicator system was made up of people, materials, environment, and management factors. The weights of factors were calculated by an analytic hierarchy process. The safety status grade was determined by a safety early-warning model. Results revealed that the safety early-warning system can reflect the safety status in freeway construction of mountainous regions objectively. 0 INTRODUCTION Safety in mountainous freeways is needed for the sustained, healthy, stable development of the construction industry and essentially guarantees steady politics, stable society, and people living and working in peace and contentment. It is necessary to establish an early-warning system in freeway construction in mountainous regions for long-term and standard safety management. It helps to take corresponding measures quickly and efficiently to improve safety management in the event of accidents. The system monitors and controls the construction safety status. On one hand, it can take established management measures for restoration if accident ICCTP 2009: Critical Issues in Transportation Systems Planning, Development, and Management ©2009 ASCE 1523
