As cities heat up due to climate change and urban congestion, mist cooling systems at traffic signals offer an innovative, eco-friendly way to improve air quality, reduce heat stress, and enhance public comfort. Whether you're a commuter, pedestrian, or traffic police officer, these systems can transform intersections into refreshing urban oases.
Why Use a Mist Cooling System at Traffic Signals?
| Benefit | Description |
| Ambient Cooling | Reduces surrounding temperature by 5–10°C using evaporative cooling |
| Pedestrian Comfort | Provides relief for people waiting to cross or in crowded sidewalks |
| Traffic Police Well-being | Keeps on-duty personnel cool in high heat zones |
| Pollution Control | Mist helps settle dust and particulate matter (PM2.5/PM10) |
| Urban Heat Island Mitigation | Cools micro-climate in concrete-heavy intersections |
How the System Works: Components & Design
| Component | Details |
| High-Pressure Pump | 2–3 HP, 700–1000 psi |
| Anti-Drip Nozzles | Stainless steel or brass, 10–15 micron mist |
| Frames or Poles | Mounted on traffic signals, medians, or overhead crossbars |
| Water Source & Filters | RO/soft water + 5-micron filter to prevent nozzle clogging |
| Automation Panel | Timer-based, or IoT-integrated with heat/humidity sensors |
| Solar Power Option | Ideal for sustainability or off-grid deployments |
Installation Points
- Traffic signal poles
- Pedestrian crossings
- Motorcycle/bike stop zones
- Central medians or islands
- Police kiosks at busy intersections
Estimated Water & Power Consumption
| System Size | Nozzles | Water Use (L/hr) | Power Requirement |
| Small (1 pole) | 5 | 40–60 | ~1 HP |
| Medium (4 poles) | 20 | 160–200 | ~2–3 HP |
Smart Control Options
- Temperature-Based Activation: Mists when ambient temp exceeds 32°C
- Scheduled Timers: E.g., 10 minutes every 30 minutes
- Manual Override: For local traffic staff
- IoT-Based Controls: Real-time monitoring, remote scheduling via mobile/web dashboard
Environmental & Social Benefits
- Reduces urban heat islands
- Improves comfort in traffic congestion
- Supports health and wellness of traffic staff and public
- Enhances city aesthetics with visible mist and cooling zones
- Can be integrated with green urban infrastructure projects
