Project Background
With the rapid development of smart transportation infrastructure, cities and road management agencies are actively seeking safer and more visible crosswalk solutions.
Traditional painted zebra crossings often become invisible at night—especially in areas with low street lighting, heavy rain, dense fog, or continuous high-traffic wear. Over time, standard road markings fade, crack, and demand costly, repetitive maintenance.
To solve these safety hazards, a smart zebra crossing projection light solution was deployed as part of a road safety upgrade project in Meixian District, Meizhou City.
However, off-the-shelf projection lamps fell short. The local road topography, custom zebra crossing dimensions, pole mounting constraints, and existing power supply system required a fully tailored OEM optical and hardware solution.
Project Challenges: Why Standard Products Were Not Enough
During the site evaluation, our engineering team identified three core challenges:
1. Complex Road Alignment and Positioning
Every intersection presents unique site geometry. Existing markings often feature:
- Non-standard stripe widths and spacing
- Severe surface wear, cracking, or partial fading
- Dimensional offsets caused by previous road repaving
A generic projection slide would project a mismatched pattern over the road, creating visual clutter rather than safety.
2. Environmental & Optical Distortions
Projection performance varies significantly based on local conditions:
- Road incline, tilt, and uneven surface angles
- Non-standard mounting heights on existing poles
- Severe ambient light pollution from streetlights and commercial signs
Without specialized lens selection and beam calibration, projected images easily become stretched, blurry, or washed out.
3. Rigid Site Mounting Limitations
Municipal projects often require retrofitting rather than replacing infrastructure. The system had to seamlessly adapt to:
- Pre-existing traffic signals and utility poles
- Varied voltage availability on-site
- Extreme outdoor weather exposure
Our OEM Customization Solution
To address these hurdles, our optical engineering team developed a complete end-to-end OEM customization strategy.
1. Custom Gobo Pattern Alignment & On-Site Practicality
We collected comprehensive site dimensions—including crossing layout width, lens-to-road distance, beam throw angle, and mounting height. Using these optical parameters, we customized the gobo lens patterns to achieve exact 1:1 alignment with existing road lines.
Field Insight: Optimizing Color for Driver Perception
During site testing, the initial plan called for a bright red zebra projection. However, on unlit rural stretches, red light alone failed to provide sufficient contrast. The engineering team shifted to a high-contrast white pattern designed to maximize driver reaction time, prompting motorists to reduce speed well in advance of the pedestrian zone.
2. Tailored Optical Lens & Illumination Design
Due to special‑site conditions, our engineers held in‑depth requirement discussions with the project party and carried out repeated product refinement and design iterations.
Since red markings were not conspicuous enough to illuminate road surfaces for safe pedestrian crossing, could we come up with a better solution? Installing lights is a viable option for pedestrian safety — but is there a way to achieve both goals?
After extensive deliberation, our engineers proposed an innovative zebra‑crossing cut‑off lighting solution. Instead of traditional colored zebra‑crossing markings, high‑power lamps are deployed. The lights activate instantly when pedestrians come within three meters of the induction sensors.
This proposal was highly commended by the engineering team. By rethinking the approach, it delivers enhanced safety for both pedestrians and vehicles.
The initial cut‑off lighting setting triggered lights within 1‑meter distance with a 15‑second response time. Through repeated testing and optimization, it has been upgraded: lights turn on within 3 seconds once pedestrians are within 3‑meter detection range.
This new solution was installed even amid typhoon‑prone weather. It gained wide popularity on Douyin, where many netizens commented that the installation greatly improved road‑crossing safety.
To maintain sharp contrast without blinding oncoming traffic, we customized:
- Custom Optical Lenses: Selected specific throw angles to prevent optical distortion.
- Anti-Glare Optics: Directed maximum illuminance onto the asphalt while eliminating glare for drivers.
3. Hardware Adaptation & Pole Retrofitting
To cut down on civil engineering costs, our hardware team provided modular mounting solutions:
- Universal adjustable pole brackets compatible with existing municipal utility poles
- High-efficiency thermal housing designed for continuous outdoor operation
- IP-rated weatherproof enclosures built for rain, dust, and temperature swings
4. Smart Sensor & IoT Integration
For advanced smart city installations, our projection units can be integrated with optional hardware modules:
- Radar & Doppler Detection: Triggers projection only when pedestrians approach.
- Traffic Signal Sync: Flashes or changes pattern states in sync with pedestrian crossing lights.
Engineering Support & Project Delivery Workflow
A successful smart traffic deployment requires more than hardware supply. We support system integrators and contractors through every phase:
- Site Assessment & Optical Modeling: Customers provide intersection photos, pole dimensions, and site specifications. We run optical simulations to design the exact setup.
- Factory Customization & Precision Calibration: Gobos and optics are manufactured, tested, and pre-calibrated to match target site coordinates.
- Field Support & Guidance: We supply comprehensive installation manuals, wiring diagrams, and technical documentation for smooth project acceptance.
Key Application Scenarios
Our customized zebra crossing projection solutions are ideal for:
- Unlit & Rural Highways: Restores nighttime visibility where street lighting is sparse or non-existent.
- School & Hospital Zones: Delivers high-visibility warnings in areas with high foot traffic.
- Urban Intersection Upgrades: Modernizes crosswalks without expensive road repaving.
- Scenic & Tourist Districts: Blends functional safety with customized visual patterns.
