The invention discloses an intersection pedestrian safety assessment method based on truck right-turn inner wheel difference blind area occupied space prediction, which comprises the following steps: constructing a truck radial distribution model and a steering angle distribution model, predicting a truck movement reachable position within a time interval T, and predicting the occupied space of a truck right-turn inner wheel difference blind area according to the truck movement reachable position; constructing a pedestrian radial distribution model and a steering angle distribution model, predicting a pedestrian motion reachable position within a time interval T, and predicting a pedestrian motion occupied space according to the pedestrian motion reachable position; and on the basis of the truck right-turn inner wheel difference blind area occupied space and the pedestrian movement occupied space, pedestrians appearing in the truck inner wheel difference blind area are predicted, and the truck-pedestrian collision risk based on the truck right-turn inner wheel difference blind area is evaluated. Potential safety hazards caused by low response speed of a driver or low sensitivity of a sensor are reduced.
