The impact of environmental factors on driving behaviors is generally qualitative as it is hard to be quantified. To determine to what extent environmental factor impacts driving behaviors, 30 drivers were selected to participate in a dynamic spatial distance experiment as per the principles of typological psychology. The study showed that different drivers had same distance perception variation pattern, with the human factor being removed. During the driving process, the space between the vehicle and the obstacle ahead was a zone with borders. The time to contact the border decreased as the vehicle speed increased, and it was influenced by the subjective judgment of collision possibility. The driver generally expected that the time to contact the border would increase. With a constant vehicle speed, the perceived distance would be reduced to adapt to the judgment of driver; with the same spatial distance, perception distance rapidly decreased to adapt to the vehicle speed increase. The above rule functions to meet the demand of driving safety.
