The LiangDao Mobile Station is a set of roadside sensing workstations that can be deployed flexibly. It is equipped with perception algorithms to detect real-time traffic objectives
. A variety of post-processing tools are provided to support multiple application scenarios such as data collection, roadside perception, ground truth testing & evaluation and digital twins. The Station is suitable for urban intersections, straight roads, proving grounds, highways, tunnels, subways, harbors and other environments.
The hardware part of the mobile station can flexibly match different types of sensors, such as LiDAR, radar, camera. It features a revolutionary 360° scanning design with 90° vertical FOV. Its power is supplied independently. At the same time, it has an electric lifting function for easy opreration by a single person, which make the Station be able to meet the requirements of different height application scenarios.
Roadside Ground Truth System
LiangDao Intelligence Roadside Ground Truth helps realize target-level environmental sensing by installing high-precision sensing base stations on the road side, and outputs reliable and high-precision environmental ground truth through the data processing platform.
LiangDao Intelligence Roadside Ground Truth can support autonomous testing and validation and help to build roadside scenario database for roadside sensing systems, and can also provide data basis and high precision traffic information for autonomous driving related algorithm training.
It consists of four main components:
LDTelescope® Hardware: high-resolution LiDARs, detect objects accurately through 3D point cloud and vision information fusion, assist in precise positioning.
LD MEC: edge computing unites, process real-time raw data from sensors and output accurate lane-level target data.
LD Data Platform: post-process data acquired by sensors and output roadside ground truth.
LD KPI: validate devices under test with the pro-processing ground truth and output roadside sensing performance report.
Intelligent and Connected Proving Ground
Intelligent and Connected Proving Ground is a digital and intelligent upgrade solution for autonomous driving prove ground. With road-side sensing technology, 5G technology, digital twins, and cloud control platform technology, the proving ground will have digital twins capability, vehicle-road cooperation and testing capability, to achieve safe, efficient, and even unmanned testing purposes.
The whole system consists of roadside sensing, edge computing, cloud control and digital twins platform. LiangDao roadside sensing base station and perception fusion platform can provide precise perception data.Then the cloud control platform realize the cloud-based perception and decision-making to implement function of visualization, testing and V2X, so as to assist and control AD or ADAS vehicles.
City Holographic Intersection
Holographic intersections are the main focus of the city's intelligent transportation infrastructure renovation. Traffic participants are diverse and complex, including pedestrians, cyclists, bicycles, motor vehicles and others, so that holographic intersections construction needs precise data.The multi-sensor fusion intersection sensing system allows simultaneous detection of static and dynamic targets to realize holographic detection of the intersections.
LiangDao City Holographic Intersection Solution, with the LiDAR and Camera sensor hardware configuration, can transmit multi-source perception data to the edge computing units. Then ECU integrate and process the data, output high-precision target-level data, to provide target-level information for intelligent connected vehicles and autonomous vehicles to realize vehicle-road cooperative driving at holographic intersections.
At the same time, perception data uploaded to cloud platform can provide richer data for the existing traffic control system, improve the accuracy of system analysis, and provide strong data support for the relevant management departments to realize efficient command and dispatch, scientific disposal, joint operation and rapid response.
Tunnel and Highway Perception
Tunnels, a key special section on the highway, has pain points of insufficient light, big accident hazards, emergency disposal difficulties. LiangDao Intelligence launched roadside sensing solutions focusing on tunnel scenarios.It can get accurate traffic targets (static and dynamic) at tunnel entrances , exits and inside the tunnel by installing roadside sensors on the tunnel side. Meanwhile, the target data will be transmitted through network to the vehicles in the tunnel and the platform side, to help build an integrated management model of "monitoring, control, disposal and decision-making" for the twin simulation platform with multi-level refinement of the tunnel. The solution can improve the level of safety , efficiency and the intelligent management of the tunnel.

At the beginning of 2021, LiangDao Intelligence cooperated with Great Wall Motor to start the automatic testing of test car at the National Intelligent Vehicles and Smart Mobility(Beijing-Hebei) Demonstration Zone.
In December 2020, the roadside sensing fusion system LDTelescope® installed by the roadsides in Fangshan, Beijing and realized the intelligent upgrade of testing roads.
In 2020, LiangDao Intelligence cooperate with China's leading operation platform of Intelligent and Connected Vehicle Demonstration Zone to support the application of V2X.
LiangDao Intelligence and the government of Solingen and Ingolstadt are collaborating to deploy LiDAR system on city roads to help explore the intelligent management of city traffic.
