The Research of the optimization of geographical location estimating scheme of the Vehicle Collision Accident Self-alarm System

In order to raise the efficiency of the service center of Vehicle Collision Accident Self-alarm System, according to the positioning information from GPS module, we formulated the estimating scheme of vehicle position which based on geographical leveling. This paper will utilize the Weighted Analysis and put Hubei province China as example, to compare the estimating results of two schemes through theoretical calculation, thus coming up with an optimized geographical leveling and position estimating scheme.
