Research on Optimization of Graphical Scheme for Large Plane Cross Signs

In order to find a practical graphical layout of the plane cross sign and the corresponding intersection road information expression method, and effectively solve the multi-attribute information transmission problem of intersecting roads, the drivers’ eye movement characteristics and the visual response time was analyzed when recognizing the signs with different graphic scheme designs and intersecting road information expressions. The tests were divided into static test and dynamic test by using SMT ETG 2W and Tobbi X20-30 eye trackers. The study found that under the condition of three road name information, comparing the graphical layout with both the intersecting road number and road name and the graphical layout which expressed none information of intersecting road for the large plane cross signs, it is equivalent to the addition of two pieces of information. And the conclusion for six road name information is more obvious
