    Default Research on Cycle Tracks

    Very interesting study.

    You can also just jump to the conclusions if you like…

    "Contrary to AASHTO’s safety cautions about road-parallel
    paths and its exclusion of cycle tracks, our results suggest that
    two-way cycle tracks on one side of the road have either lower
    or similar injury rates compared with bicycling in the street
    without bicycle provisions. This lowered risk is also in spite of the
    less-than-ideal design of the Montreal cycle tracks, such as lacking
    parking setbacks at intersections, a recommended practice."

    What is already known on this subject
    Individuals, in particular women, children, and seniors, prefer
    to bicycle separated from motor traffic.

    Cycle tracks (physically-separated bicycle-exclusive paths
    along roads) exist and continue to be built in The Netherlands
    where 27% of all trips are by bicycle and 55% of bicycle riders
    are female.

    Engineering guidance in the United States has discouraged
    bicycle facilities that resemble cycle tracks, including parallel
    sidepaths and sidewalk bikeways, suggesting that these
    facilities and cycle tracks are more dangerous than bicycling
    in the street.

    What this study adds
    Overall, 2 ˝ times as many cyclists rode on the cycle tracks
    compared with the reference streets.

    There were 8.5 injuries and 10.5 crashes per million-bicycle
    kilometers respectively on cycle tracks compared to published
    injury rates ranging from 3.75 to 67 for bicycling on streets.
    The relative risk of injury on the cycle track was 0.72 (95%
    CI=0,60-0.85) compared with bicycling in the reference
    streets.

    Cycle tracks lessen, or at least do not increase, crash and
    injury rates compared to bicycling in the street.

    Having a look at the current statistics is helpful when evaluation design alternatives. Thanks for sharing this, consider yourself welcome here!

    Another dimension to cycle tracks is the cost per mile to implement (which can be very site-specific), though can be the deciding factor in whether or not the cycling feature is added.
