The current trend of ITS (Intelligent Transportation System) applications is to use e-Automation control and data processing platforms. Many principalities are installing platforms in highway, freeway, and city transportation systems. These systems handle speed auditing, dynamically displayed LED signboards, and traffic signal control systems.

In recent years, the ITS market has experienced a major upswing worldwide. Freeway tollgates make use of many types of serial equipment, such as speed detectors, searchlights, and cameras. By using Moxa CP-168U V2, CP-104UL V2, and other Moxa multiport serial boards, we can connect all types of serial equipment to an IPC, allowing the host computer at the tollgate to collect information sent from IPCs via modems through Moxa C320T/PCI (max 128 ports). The information can be sent back to the tollgate center for processing and further analysis, resulting in a more powerful, efficient, safer, and automatic freeway transportation system.
