Innovation Questions

Questions How can we
  • How might we develop locally sourced, innovative materials for road markings that withstand high temperatures (+50°C) and last at least 5 years?
  • How might we integrate smart paint technologies or photoluminescent (glow-in-the-dark) materials that enhance night visibility without external electricity?
"What if" questions
  • What if we replaced traditional paints with heat-resistant plastic strips or recyclable composite materials that can be installed in under an hour without closing the road?
  • What if we used embedded sensors in road markings to collect data on wear and friction and send proactive maintenance alerts before deterioration occurs?
