ITS can apply to roadway signal control, subway or the tunnel monitoring system. The ITS is managed from a central system, and a set of sub-systems, such as signal control system, environment monitoring control System, fire detection system, fire distinguish system, supervisor control and data acquisition system, automotive fair collection..etc. To establish a reliable and stable network communication system is always the challenge & core value of Intelligent Transportation system. Acrosser ACS-R1000/R1001 can be served as the embedded computing, connecting to the sensors, related devices of sub-system, and its 6 GigaLAN port also provide sufficient capacity to handle large amount data transmission, help to secure the connectivity required in traffic applications, including roadway, bridges, metro systems, and tunnels.
