I just wanted to share this article showing evidence of car use reduction (and therefore, car traffic along roads) with the provision of bicycle lanes.

Building Bike Lanes Really Does Get More People Out of Their Cars

The article though cautions readers against generalising or assuming great improvements. Some figures mentioned in the article including the following (I took the liberty of copying and pasting):

• “A 10% increase in bike accessibility resulted in only a 3.7% increase in ridership.”
• “…cycling infrastructure also reduced greenhouse gas emissions from cars by 1.7%, a reduction equivalent to converting transit buses to hybrids and electrifying commuter trains.”

These numbers are for the case of Montreal, Canada. Not mentioned are the number of cyclists, vehicle traffic volumes and other pertinent data that are useful in analysis. The article correctly points out the importance of using science (e.g., sound analysis based on good data) in order to convince governments to put up bicycle infrastructure. I would even add that this approach should also be applicable to pedestrian facilities.
