This paper describes a location based service approach for the prevention of large haulage equipment collision accidents involving concrete buckets during dam construction phase. A review has been provided on the background relating to common collision avoidance on construction sites. It is of upmost importance to establish a collision warning system in a pro-active real-time mode for the specific environment of dam construction. The location based service combines wireless communications, GPS and GIS technologies for a continuous operation to address this problem. A system design is proposed with a location based defined function. In this paper, the design algorithms for warning and guiding in different operation modes are detailed and discussed. They are formulated to automatically detect any potential hazards, alert drivers, thereby avoiding collision, and to provide reliable navigation. A set of preliminary tests show that the system prototype is a feasible option in fulfilling the collision warning function, as well as a practicable option when linked with automation and visualization in the dam construction process. Development of such an integrated technology assisted location based service approach to a collision warning system has a significant impact on the application of the safety systems on construction sites, and also promotes efficiency management in the project.
