This Traffic Control application demo (viewed as a Java applet). This applet is portable, performs exceptionally well and is highly compact -- less than 170K! The applet could be easily customized via simple text files, without any modification to code.
This application is less than 170K, including the map layering, the vector font, the icons, and all interactive behaviors. Maps are stored in a binary format tailored for map poylines resulting in optimum compression and faster downloads.
The map data set parameters are set from user-defined text file which is read by the applet at runtime so it is easy to reconfigure without changing code.
The Symbols are GIF images and are dynamically instantiated from simple text files. The text files contain records describing each icon and its attributes. The information dialogs are GMS models.
This demo could easily be extended to develop a more complete Traffic Control application.
