Variable Message Signs (VMS) are quite commonly used for the traffic warning information of road & bridge construction, fire-fighting, parking lots, etc. The high brightness and strong eye-catching LED technology deliver the traffic information to the driver, remind them to focus on their driving speed and pay attention to the weather, road situation, and so on. It can reduce the traffic accident by deploying the road traffic management.





●Smart monitor

E-RAOD VMS can activate self-diagnosis and report health status, monitor can identify equipment health status, current message ID,current operating mode temperature, humidity, etc

●Energy-efficient

Industry-leading dual-voltage technology, it can tremendously improve energy efficiency and maximumly lower light pollution.

●NTCIP and MODBUS based

E-RAOD avriable message sign are programmed based on the world two most prevailing 1.programmed NTCIP (NationalTransportation Communications for ITS protocol) and Modbus, more than just that, we also provide customized protocol if necessary.
