Road traffic accident multi-happening section identifying method

The invention is concerned with the distinguishing method for the road with more traffic accident. The invention uses double target of alpha-gamma to distinguish the road with more traffic accident, assigns the remarkable level alpha, according to the Poisson probability formula or the frequency accumulation chart, after computes the critical value gamma of the high accident number and the critical value R of the high accident rate, compares the gamma and the R of the un-distinguish road to get the distinguishing result of the road with more traffic accident.
