Original sentence: A 2008 report shows that bicyclist fatalities and injuries has generally trended down over the last ten years in the USA and similar results are documented in Canada and other countries (see "A Guide for Reducing Collisions Involving Bicycles," Volume 18, report 500, NCHRP).Advocacy science is poor science.Caution is advised: The following article lacks a neutral point of view.Given that cycling lanes and other cycling specific facilities have become more popular over the same period, it suggests that they may be a significant contributing factor to greater cycling safety.In addition the authors of some of the documents referenced below are adopting a tone that is more advocacy than science.It does not comment on the quality of the documents referenced and the publications in which they are found, if they are peered-reviewed or not.Much of the documentation is outdated and almost all of it is one-sided.The article almost always adopts the conclusions at face value.Vehicular cyclist advocates, who are against cycling lanes, are not the most objective people to review the safety record of such cycling specific facilities
