Road Simulation System In The Driver Model

Highway Simulation Technology is an integration of highway technology, vehicle technology, driver behavior, information technology, control technology, and it is very significant to highway alignment estimation.In this paper, one of above was researched. On the basis of path-preview theory, driver direction control model was established; Land coordinate system was imported as a frame of reference, which tightened the combination of driver model and route alignment; vehicle turning property was considered to research the variety rule of the angle of steering wheel; preview strategy was used to control the path. In speed control model, Distant Sight Point and Index of Accelerate Probability were defined in combination with the influence which route geometric property exerted on driver manoeuvre characteristic. Desire Speed was introduced as an expectation for driver speed control procedure. With above aspects been considered, the acceleration rule under the synthesized influence of alignment and current velocity was researched and the driver acceleration decision-making behavior model was established. In the integrated develop environment of Visual Basic 6.0, computer program was compiled for simulating experiment. The production of this paper can also be utilized to estimate route alignment objectively.
