Improving guide sign legibility: new lettering reads larger, clearer, farther
The traditional lettering design on highway guide signs, which is usually fully retroreflective, was found in a 1994 study by the Federal Highway Administration to be inadequate for older drivers. Research by the Texas Transportation Institute, building on research findings of the Pennsylvania Transportation Institute, determined that the Clearview font on guide signs, combined with retroreflective sheeting for white Clearview text on a green background, using the most efficient microprismatic materials for the legend with high-intensity materials for the background, yielded a win-win situation. The signing agency gains durability and cost-efficiency in the signs, and drivers gain contrast, which is beneficial for legibility in dark conditions.
Taking the construction of "reading fun" of the library of Sanjiang University as an example,this paper expounds in detail the background and work ideas of constructing the network-based reading guidance platform and the functions of each module,and probes into the construction and operation mechanism of the platform.
