Required Road Conditions for Setup of Weigh-In-Motion (WIM)

Criterion to be verified
Requirements
Category A
  • 'No Lane Violation' Zone Ahead
  • Stable tramc (No tramcjam)
  • Availability of electrical power
  • Network availability for data communication
Category B
  • Straight road (visual inspection)
  • Without longitudinal slope (visual inspection)
  • Small transversal slope (visual inspection)
  • Flatness (no ruts, no bulges)
  • Quality (no cracks)
  • Depth of Road > 90mm
  • Road MSA > 60
  • Rutting on Road < 2mm
Note: We need the road condition as per above-mentioned criteria, along with this the road quality plays a very crucial role.  This WIM sensor is highly sensitive and can't recommended to re-install for accurate result. Therefore, we need to ensure the road quality at the proposed location must be good and durable for at least 3 to 5 years. In case any bulges develop on road, the sensor will be exposed, leading to inaccurate results.
