Forecasting research on the driving safety perception of horizontal curves

Aiming at the problem that horizontal curve radiuses have some different influences on the formation of driving safety perception. Formatting model of driving safety perception to curve is built based on combined actions of components of bend and running speed of vehicles. Fuzzy-neural networks model of driving safety perceptive formation and fuzzy inference rules are built up. The results of inference operation and road test prove that the relation between input and output is reflected accurately. By utilizing inference ability of the trained model, the simulation results show that the influence of different horizontal curve radius on driving safety perception under different running speed.
