Emergency Accident Rescue System in Freeway Based on GIS

A reduction in accidents, particularly secondary ones, is often cited as one of the primary benefits of an emergency accident rescue system in freeway (EARS). In the context, the requirement of EARS in freeway was analyzed, a holistic framework and procedure for the EARS based on GIS is structured. This system design a combination of model of C/S and B/S using VS2005, it mainly includes two models. The first is early warning and positioning the traffic accident, the second is rescue creation for automatic generation of a rescue plan. Using the system in the management of freeway would provide decision-making supporting of the safe operation. And this study will provide a model and reference for the development of early warning and rescue command system in the freeway.
