Implementation of a Low-Cost Weigh-In-Motion System

Cassandra Isackson

Why is this a priority for the State/County/City? : The crystalline-quartz WIM sensors currently cost about $24K per lane. The ceramic sensors would cost less than half that amount. This would allow us to monitor vehicle weight at more sites and make it more cost effective to monitor at sites with lower volumes.

Project Type - MnDOT or LRRB / Research, Implementation or TRS:
MnDOT Implementation
Idea Status (moderator):
Develop implementation plan for Feb. 27 TRIG meeting

Ceramic piezo-electric sensors are cheaper than the conventional crystalline-quartz piezo-electric sensors but they are overly sensitive to temperature changes. During the development of the Portable WIM system (Report 201238), a potential method was developed that could allow the use of the ceramic sensors and maintain the same accuracy that is only available with the crystalline-quartz sensors. This project would be to convert the portable WIM system that was developed and install it at a fixed location and test it against a crystalline-quartz system.
