Evaluation Method of Drivers Vision Impacts from Green Belts of Arterial

摘要

As an important part of the cross section of road, the green belt of urban road has heavy impacts on the drivers' visual environment. Green belt directly relates to traffic safety. But the research on this area is only carried out from the aspects of color and monotonicity. Few research can be found which is about impacts indexes. In this article, the impacts model of green belt is established. The green belts impact value of the different level and different section is obtained by expert method. In order to validate the model, an eye movement instrument (SmartEye) is adopted. The data of impacts indexes can be obtained in SmartEye. Then, ErgoLAB package is used to identify the drivers' gaze points during the course of the experiment and to generate the view distribution map of the gaze area. After this, the experiment in driving simulator dome under variable traffic flow condition is carried out to modify the model built above. At last, a recommended rating grade standard is presented.
