ILS-04 Laser-Based Free-Flow Vehicle Length, Width, and Height Detection System
Multi-lane free-flow system
Side-mounted free-flow vehicle outline detection system—no gantry required; a single-point side installation is all it takes to reconstruct the holographic road surface.
The Multi-Channel Free-Flow System is an innovative free-flow detection system based on advanced multi-channel LiDAR technology. It abandons the traditional gantry-mounted setups and requires only the installation of tall poles on one or both sides of the road, equipped with MF100 image-grade multi-channel LiDAR sensors, to perform ultra-wide-range, three-dimensional real-time scanning of 2 to 4 lanes.
Thanks to 1550nm laser technology and high-density scanning with over 150 lines, the system can generate photo-quality 3D point clouds of vehicles, accurately measuring their length, width, and height, and boasts exceptional vehicle model recognition capabilities. Installation requires no traffic closures and no cross-road construction, significantly reducing both the complexity and duration of project implementation. This represents a new-generation benchmark solution for intelligent highway roadside perception.

Overview
Side-mounted deployment—say goodbye to rack-mount headaches!
Building overpass gantries not only involves difficult approval processes and high construction costs, but also requires lengthy road closures for construction. In contrast, multi-lane free-flow systems only require the installation of a single pole—measuring at least 6 meters—in the roadside. With deployment on just one side, these systems can cover multiple lanes, and the construction process is as simple as installing streetlights, significantly reducing both project costs and coordination expenses.
Photo-quality point cloud, with every detail vividly captured.
Equipped with the ILS-MF100 image-grade LiDAR, it boasts over... 150 lines It boasts a vertical resolution of and a horizontal resolution of 0.18°. The system no longer generates sparse lines; instead, it produces dense, real-time 3D models. Not only can it measure length, width, and height, but it can also clearly identify the type of cargo, spilled materials, and even potholes on the road surface.
Ultra-long-range perception, mastering the whole picture.
Based on 1550nm fiber laser technology, the detection range reaches up to 500 meters This means that the system can not only detect cross-sections but also continuously track vehicles over long distances, significantly enhancing the accuracy of vehicle speed detection and trajectory analysis capabilities, thereby achieving true holographic perception.

Smart sensing that requires no road closures and can be activated instantly.
The ILS-04 multi-line system is particularly suitable for: Does not meet the conditions for gantry installation. or Budget constraints the road segment. By capturing overhead views from elevated positions along the roadside, it constructs a 3D scene akin to a god’s-eye perspective. In addition to conventional detection of exceeding length, width, and height limits, it can also leverage high-density point clouds for highly detailed analysis. Vehicle Type Classification 、 Traffic Flow Survey and Congestion Queue Length Analysis It is a highly cost-effective, multi-functional transportation sensing hub.
Cutting-edge technology, delivering a dimension-reducing blow.
1550nm light source: a dual leap in performance and safety
The core radar ILS-MF100 features high-end... 1550nm Fiber Laser Compared to conventional 905nm lasers, its human-eye safety threshold is 40 times higher, allowing it to emit pulses with much greater power.
This brings two groundbreaking advantages: first, the detection range has been extended to 500 meters; second, it boasts exceptional rain and fog penetration capabilities as well as strong resistance to light interference. Even in heavy rain or when facing the setting sun, it can still deliver stable and clear point cloud data.
Single-unit coverage of multiple lanes significantly reduces costs.
Traditional solutions require installing one radar above each lane. In contrast, the multi-line system, with its ultra-wide 120° horizontal field of view, needs only one device installed along the roadside to cover 2–3 lanes in a single direction.
For wide roadways with four or more lanes, a bidirectional opposing arrangement—installing one unit on each side—ensures full coverage. Moreover, by stitching together data from two perspectives, this approach minimizes the blind spots caused by vehicles parked side by side, achieving optimal results with the least equipment investment.
150+ wire harnesses—see every single detail.
The number of cable harnesses determines the vertical resolution. The MF100 boasts a scanning capability of over 150 lines, making it a top-tier configuration in the transportation sector.
It can “capture” the three-dimensional shape of vehicles just like a high-definition camera. Whether it’s the bulging tarpaulin on the roof of a truck or the subtle dents in a bus window, everything can be clearly detected. Paired with AI deep-learning algorithms, the system achieves a vehicle-model classification accuracy rate as high as **99%**, precisely distinguishing between buses, trucks, and specialized operation vehicles.
No road closures required; completion on the same day.
For highways that are already in operation, construction means congestion and risks.
The installation of the ILS-04 multi-line system is entirely carried out on the roadside outside the guardrail, requiring no occupation of the traffic lanes and eliminating the need for complicated road closure procedures. Once the pole foundation work is completed, equipment installation and commissioning take only half a day. This “non-intrusive” construction approach represents the option that causes the least disruption to road operations.
