Transportation officials rely on Weigh-In-Motion
(WIM) sensors for collecting vehicle data at high
speeds for highway data and traffic monitoring.
Traffic volume, speed, vehicle classifications,
and vehicle weights are all part of monitoring
current usage and highway planning for the future.
Strip sensors for data collection incorporate strain gauge sensor technology:
• WIM Site Installation employs Two to Four Sensors, Loop & Electronics
• Provides Accurate Data for Roadway Monitoring & Planning
• Detection of Overloaded Vehicles & Incidence
• Integrate Sensors in Existing Pavement or during Site Replacement
Performance of WIM site has a Gross Vehicle
Weight (GVW) accuracy for data collection
which meets or exceeds ASTM 1318 Type I
and COST 323 B(10) WIM requirements.

DATA COLLECTION | CASE STUDY
NETHERLANDS: DATA COLLECTION
Just outside of Rotterdam in the Netherlands, Intercomp strip sensors are
installed in multiple lanes to gather traffic and vehicle data in the mainline.
As Rotterdam is one of the busiest shipping ports in the world, gathering
traffic and vehicle data supplies the Ministry of Infrastructure and the
Environment valuable information for roadway planning and utilization.
Sensors were installed in four lanes, with two sensors per lane for this mainline application. The WIM site
experiences high speed vehicle traffic, with significant heavy vehicles due to the commercial traffic for the port.
Additionally, one lane of traffic required bi-directional capability, so monitoring traffic in both directions was enabled
for that lane.
Delivering GVW accuracy of better than COST 323 B+(7) requirements with the bi-directional and single lanes, the
Intercomp strip sensors satisfied the requirements to provide excellent traffic and weight data for this high traffic
volume WIM site.
As the Intercomp sensors were integrated with the local operator’s electronics and software, this adds to the variety
of electronics platforms that are currently capable of working with Intercomp WIM sensors.
