The application of intelligent traffic system products greatly improves the efficiency of traffic operations by providing the back-end with real-time traffic data and also guarantees the safety of the vehicle drivers with traffic guidance. Intelligent traffic system, known as ITS, is with a whole range of products and systems, among which variable message sign, lane control sign and variable speed limit sign are most known. |

 | | | | Any VMS (variable message sign) products will be exposed to harsh outdoor environments once installed such as rain, snow, wind and sandstorms, etc. This requires the products to have high visual penetrability, effective brightness, optimal contrast ratio and durable IP Level. Display screens need to have a reliable performance to stand various weather conditions. | | | | | |
| | | | | | |  | | | | Shanghai SANSI (Shanghai Sansi Electronic Engineering Co., Ltd) was once again rewarded European Union CE CPR certificate for its variable massage sign products designated for road traffic since 2017. The acquisition of this certificate indicates that Shanghai Sansi’s VMS products meet the strict standard requirements of EN 12966-1; and meanwhile it demonstrates that the factory production process control of SANSI has reached the ISO 9001 standard and also it meets the strict requirements of additional testing and production quality of EN 12966-3. | | | |
| | | | | | |  | | | | The reason why it is called a variable message sign is that compared to ordinary information boards, the information on this kind of LED information board with integrated control systems can be freely replaced and changed. | | | |
| | | | | | |  | | | | Intelligent transportation system (ITS) is a service system for transportation based on modern electronic information technology. Its outstanding feature is based on the collection, processing, release, exchange, analyse, and the utilization of information as the pivot to provide diversified services for traffic participants. | | | |

 | |  | |  | | | | | | | | | Lane Control Signs are designed to maintain efficient traffic flow. | |
| | | | Variable Speed Limit Sign(VSLS) is an integral part of smart traffic system to better indicate speed for vehicule drivers for a better safe road environment | |
| | | | The VMS signs display messages and instructions for the drivers of the real time traffic conditions. | |
