Weigh in Motion (WIM) Systems
Our WIM Systems provides highly accurate weighing data of vehicles essential for pavement management as the damage by over-loaded trucks to the pavement is exponential as 10% increase in weight results in 40% increase in pavement damage. It also makes the roads safer as overloaded vehicles are more prone to accidents.

Why WIM:
Overloaded Vehicles Causing Accidents resulting in

  • Loss of life
  • Property Damage
  • Traffic congestions
  One form of “Weight in Motion”!!(As observed by IRDSA staff in Pakistan)
SSWIM

IRD's Slow Speed Weigh-in-Motion (SSWIM) System is a high accuracy low speed weighing approach ideally suited for commercial fleet axle weight monitoring and axle compliance.

Salient Features of SSWIM:

  • Weighing accuracy of more than 99%
  • Provides individual axle loads for determination of weight distribution, along with GVW.
  • Operates in Static as well as "In-Motion" mode
  • Facilitates automatic vehicle classification
  • Vehicle weighing time 15-20 seconds (approx.)

Application:

  • Weigh & Enforcement
  • Commercial Sleet monitoring
  • Weighing of trucks for axle compliance i.e. check the weights and weight distribution of a truck before it leaves the terminal to ensure that the vehicle complies with weight and dimension regulations

IRDSA has installed a fully functional WIM system (for demonstration) at Delhi-Karnal border. The system was installed in September 2005 and has been working without any fault with an average vehicle weight accuracy recorded at 99%.

High Speed Weigh-in-Motion System (HSWIM)

Salient Features of HSWIM

  • Weigh vehicles, in Motion at high speed
  • Pre-Sort to eliminate unnecessary delays & lineups at weigh stations
  • Preclearance based on weight & credentials
  • Integration with Automatic Vehicle identification (AVI) Systems

 
   


Application:

  • Data Collection
  • HSWIM is used as a sorter system to sort out the probably overloaded vehicles from traffic to avoid long queue at enforcement point.
