V2X Urban Area


V2X Area View

V2X urban area is a facility where you can conduct verification experiments of a cooperative automatic driving system that utilizes communication, assuming a complicated traffic environment in an actual urban area.
Equipped with optical and radio beacons for road-to-vehicle communication, it can also support the construction of a wide variety of systems to support safe driving.

Test path specifications

  • Track width: 1 lane: 2.75 to 3.5m
  • Straight road: 400m north-south straight road (including 4 lanes, 300m)
  • Intersection: 4 lanes x 4 lanes (1 location) / 4 lanes x 2 lanes (3 locations)

Auxiliary Equipment

  • Traffic light (LED)
  • Wall material for visibility adjustment (movable and installable)
  • Curb block (movable and installable)
  • Waiting room (test chamber) and tent

※There is no equipment on the test road to block the line of sight from the outside.
