  • Reduced Congestion: By balancing traffic across lanes, DLM can mitigate bottlenecks and prevent traffic jams.
  • Improved Safety: With more efficient lane usage, accidents due to congestion or misalignment are minimized.
  • Cost-Efficiency: Instead of widening roads, DLM offers a low-cost alternative that improves capacity without major infrastructure changes.

How Dynamic Lane Management Works

  1. Traffic data is gathered through sensors and cameras on the road.
  2. Real-time analysis is performed to assess traffic density and vehicle speeds.
  3. Lane usage is adjusted according to the current traffic conditions (e.g., adding lanes for a specific direction during rush hours).
  4. Information is communicated to drivers via electronic signs, indicating changes in lane assignments.

Key Technologies Behind Dynamic Lane Management
