Caiyang’s main research area is the improvement of pedestrian safety in the automatic driving environment. As part of his research, Caiyang is looking at the Mobileye's RSS model, which is a rigorous mathematical model that guide the automated vehicle properly react to other vehicles on the road to ensure safety. It is necessary to calibrate and evaluate the RSS model before applying it in real driving environment; therefore, Caiyang is building the simulation scene for vehicle-pedestrian conflict, setting objective function and optimisation algorithm (to get the optimal model parameters) and evaluating the model’s effectiveness, robustness and reliability.
