Designing an industrial subdivision for efficient truck circulation is essential to ensure smooth logistics operations, reduce congestion, and maintain safety. An optimized layout allows large commercial vehicles to access, maneuver, and exit multiple lots without reversing hazards, turning delays, or bottlenecks.
Below are the key layout features and planning principles that optimize truck movement across industrial plots:
1. Wide Internal Roads with Turning Radius Compliance
- Road Width: Minimum 12–18 meters for two-way heavy vehicle movement.
- Turning Radius: Minimum 12–15 meters at junctions and turning loops to accommodate 40-foot trailers.
- Design Note: Avoid 90° turns wherever possible; use T or loop intersections for smoother flow.
2. Looped or Grid Road Networks
- Preferred Over Cul-de-sacs: Grid or looped roads prevent dead ends and allow continuous circulation.
- Benefits:
- Avoids reversing trucks
- Supports phased lot development.t
- Enhances emergency access and utility routing
- Avoids reversing trucks
3. Dedicated Entry and Exit Points
- Provide separate access gates for inbound and outbound truck traffic to reduce cross-movement.
- Position gates along the site’s longer frontage to distribute load across the layout.
- Ensure a minimum of 30 meters of queuing length at entry points to avoid spillover onto public roads.
4. Lot Access from Internal Roads with Staging Space
- Design each lot with direct road frontage—preferably along the main or loop roads.
- Leave space for:
- Staging lanes or lay-bys in front of loading bays
- Wide driveways (6–9 meters) for trailer entry
- Staging lanes or lay-bys in front of loading bays
- Internal service lanes should be clear of obstructions, utility poles, or landscape buffers.
5. One-Way Circulation Zones
- Use one-way traffic design where space is limited or where plots share access lanes.
- Mark directional arrows, signs, and truck bays.
Supports safer and faster unloading at multi-tenant buildings or shared docks.
