Abstract:

In this study, crossing island facilities are evaluated from the conspicuity point of view. This paper provides an evaluation method to determine which kind of facilities can draw the visual attention of a driver easily with the aid of a saliency map. A visual scan experiment with the aid of eye tracking system was conducted to collect fixation percentage data. The evaluation method of crossing island facility was conducted based on image characteristics. The saliency-based model which is based on a model of visual attention built up by Itti was set up and improved through the process of Gaussian pyramid creation, visual feature extraction and conspicuity map generation as well as the saliency map generation. Mean intensity of salient zone on the saliency map is selected as an indicator to calculate fixation percentage of crossing island facility and the regression model is helpful for the evaluation of conspicuity of crossing island facility at pedestrian refuge island together with MATLAB and Photoshop.
