The paper introduces each standardization phase of the graphical symbols used in railway passenger transport services, and analyzes why railway stations can not use the standard graphical symbols in correct way.

As a national standard of traffic management domain,the standard standardizes the graphical symbols for use in TV monitoring system equipment for traffic,and lays the foundation for the standardization of the design and const.

The paper discusses some disputed theory problems in standardization field of public information graphical symbols.

Because there are different map symbols systems and interfaces in GIS softwares,between them the cartographic symbols cannot be shared.

Standardization and normalization of terminologies and graphic symbols;

When drawing through the use of MicroStation,the function "SHARE CELL" can bring convenience to graphic symbol displacement.

A novel graphic symbol recognition approach of engineering drawings based on radial basis probabilistic neural networks (RBPNN) is proposed.
