In population density, traffic congestion of metropolitan areas, often because of traffic congestion and delay time, how effective traffic control is very important. Signal control system to provide safe, automatic, real-time traffic control, safe and efficient traffic flow to ensure smooth traffic.

The existing signal controller's management, the main link is the main line, a new signal controller of the management, except in the early days of the completion of wiring planning to build, or the need for excavation and wiring work, the Department of were accounted for the majority of projects, the existing management units often have problems that is, green line, largely due to a road or water excavation, and other factors, but these factors have to be relevant institutions to carry out repair care, often non-urgent need for relief of no use, so often have to use human-assisted control signal. For the adoption of wireless, as a general signal controller for the proprietary systems, and the system is not built-in wireless-related driver, it is necessary to complete the GSM / GPRS to connect to AT Command or TCP / IP design of the investments required is enormous.

Consider these issues, MA8-2 with the traffic signal controllers using RS-232 connection, the traffic is entirely without change existing program settings, and writing can be connected, MA8-2 provides built-in graphics interface, can be set in accordance with the traffic protocol and data format for data transmission, and the other by the competent authority to address the situation of demand for screening, to filter out unnecessary information, through the GPRS system and the combination of Internet will return the traffic information control center. Gateway can also be completed with the existing traffic control center of the combination of equipment, communications equipment and save a lot of wire, management and maintenance is also easier to build systems quickly and cost savings for the system integrators the best solutions.
