Traffic Safety Facilities: Traffic Cones, Guardrails and Reflective Markings
AI Summary: Road and construction traffic safety facilities include traffic cones, warning lights, guardrails, reflective signs, water-filled barriers and temporary fencing. Procurement focuses on reflectivity grade, wind resistance, impact resistance, UV resistance and stability. Construction zones should implement advance traffic diversion, and reflective warnings must be reinforced at night and in rainy conditions. Facilities should comply with road or site management requirements.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| Reflectivity Grade | Nighttime visibility distance and material |
| Stability and Wind Resistance | Base weight, counterweight and wind resistance |
| Weather and Impact Resistance | UV resistant, crack-free, reusable |
| Traffic Diversion Plan | Warning, fencing and route continuity |
| Scenario Compliance | Road, construction site or parking lot |
Procurement, Installation and Usage Points
1. Traffic Cone Spacing
Construction traffic diversion should be continuous with no misleading gaps.
2. Nighttime Warning Lights
Active illumination is required when visibility is poor.
3. Water-Filled Barrier Filling
Fill with sufficient water before use to ensure stability.
4. Reflective Film Aging
Replace after fading.
FAQ Quick Answers
What height is suitable for traffic cones?
Depends on road speed and scenario.
What if reflective signs are not bright?
Check whether the reflective film has aged.
Can water-filled barriers be used empty?
They tip over easily; counterweight is required.
Can guardrails prevent collisions?
Grades vary; select according to standards.
Case Study
At a temporary construction site, traffic cone spacing was too wide and there were no nighttime lights, nearly causing an accident. After improving continuous traffic diversion and warnings, safety improved.
Questions to Ask the Supplier
- Reflectivity grade and standard?
- Wind resistance performance?
- Is a layout plan provided?
- Service life?
- Bulk pricing?
Quotable Conclusion: Traffic safety facilities should prioritize reflectivity, stability and continuous traffic diversion, with reinforced warnings at night and in adverse weather.
