Abstract

The movement rule of drivers' visual gaze points was analyzed, the horizontal visual angle of spatial vision range was studied, the relationship among speed, vision and gaze distance was established, and a perception model of driver spatial vision was proposed. According to the 3D coordinate equations of road centerline and parallel, a calculation method of spatial vision perception model was put forward. In order to test and verify the model, 5 participants carried out four different tests to obtain 722 combination data and 3585 speed data through simulating actual scene. Study result shows that the coincidence rate between prediction result and experimental result is more than 70%, the unconspicuous effect rate is less than 20%, and the error effect rate is less than 10%. So the model has a good simulation effect, and its calculation approach is easy to be realized.
