Incorporating Saliency Map into Appraisal of Crossing Island Facilities: From Point of View of Drivers’ Visual Attention

In this study, crossing island facilities are evaluated in conspicuity point of view. This paper provides an evaluation method to determine which kind of facilities can draw visual attention of driver easily with aid of saliency map. The 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 based on model of visual attention built up by Ltti 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 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.
