Bicycle Data – “We Measure What We Value”
People are increasingly turning to the bicycle as a viable mode of routine transport.
Some factors:•Offsetting the increasing costs of living.•Reducing environmental impacts.•Healthy lifestyle.•Making cities more liveable and sustainable.

Designers and engineers need accurate bicycle VOLUME data for:
•Monitoring usage of existing facilities.•Planning and designing new facilities.
Many monitoring sites have been or are being established.
But…
Bicycle volume data only provides a partial picture.

Bicycle SPEED data is also required for:•Monitoring & designing for safety.•Accurate modelling & planning.
But…
How can we obtain bicycle VOLUME data?
How can we obtain bicycle SPEED data?
And…
How can we obtain bicycle data ACCURATELY?

O PBicycles may be recorded with inductive loops or piezoelectric strips, but...
Why use piezo strips?

Bicycle Data – “We Measure What We Value”
Independent tests - By Grontmij B.V., Rotterdam, Netherlands
“In September 2013 Grontmij conducted tests with three bicycle counting systems at Kralingseweg, Rotterdam. Besides the Dinaf count tubes already present at the test location, two other counting systems were deployed for the tests:• MetroCount MC5720: using piezoelectric strips;• EcoCounter: using an induction loop glued to the bicycle path.”
“Results… EcoCounter showed the biggest deviations from reality”

Bicycle Data – “We Measure What We Value”
Independent tests – SKM, Melbourne, Australia (cont.)
“A Metrocount MC5720 bicycle counter was installed on Albert Street (East Melbourne) in the citybound (west) direction on Wednesday 22 June. As most installations of this piezo sensor were previously on off-road shared paths there is a need to understand whether motor traffic in the adjacent traffic lanes interfere with the sensor.”
“Results… The overall count accuracy of the MC5720 was very good”

Advantages of the MC5720 include:
Excellent signal-to-noise ratio.
Broad speed response.
Low profile.
Cluster separation – separates clusters of bicycles.
Ultra-low power consumption.
Synchronous second channel – time-stamp other sensors, such as pedestrian counters.
