  WanJi has great achievements to apply LiDAR in Intelligent Transportation System (ITS) industry. WanJi LiDAR WLR-711 would perform three major functions:

  l  Vehicle classification

  2  Traffic data collection (vehicle counting, speed measure and vehicle classification)

  3  Vehicle dimension measurement (length, width and height).

  Additionally, WanJi develops laser sensor to achieve induction and vehicle separation functions in Weigh-In-Motion Direct Enforcement System and Multi-Lane Free Lane system.

  The LiDAR has high point density and smaller divergence to achieve better digital quality. As a result, clients could collect invaluable traffic data for toll system and traffic infrastructure planning. WanJi has installed thousands of LiDAR equipment to demonstrate LiDAR is reliable and has great adaptability in extreme weather.
