Portable Work-Zone and Solar Traffic Signal Planning Guide
A field checklist for temporary road works, remote locations and off-grid intersections where traffic signals must be moved or powered independently.
When portable or solar signals make sense
Temporary road works, bridge maintenance, emergency diversions and remote crossings may not have a permanent cabinet or mains supply. A portable or solar traffic signal can reduce installation time, but the system must be planned as a complete set of signal heads, controller, battery, charging and mounting hardware.
Site-planning checklist
| Planning item | Questions to answer | Evidence to provide |
|---|---|---|
| Traffic layout | How many approaches and phases are needed? | Temporary traffic plan or sketch |
| Power | How many hours of autonomy are required? | Daily operating hours and weather assumptions |
| Wireless sync | How are two or more heads synchronized? | Distance, obstacles and preferred control method |
| Mobility | How often will the unit be moved? | Vehicle access, stand or trailer requirement |
| Safety | What visibility, warning and local standard apply? | Country, road class and project standard |
Portable versus solar
Portable systems prioritize quick deployment and transport. Solar systems prioritize independent power and may require a larger battery and panel for winter or cloudy conditions. If both are needed, confirm the folded dimensions, charging method, wireless synchronization and local manual override.
Compare the mobile traffic light, solar wireless signal and solar wireless controller ranges, then use the solar site survey before ordering.
