This article is a literature review of 139 studies that looks to find the most effective interventions for increasing use of bicycle facilities. In the conclusion (pg. S122) they raise the concern that most plans and interventions set no useful means of evaluation. The authors stress that strong policy is needed to sustain any measures to promote additional cycling and show that aggregate studies found a positive and statistically significant relationship between bike lanes and levels of bicycling, whereas the individual-level studies had mixed findings (pg. S107). Tables 1 and 2 (pages S108-S111) provide guidance to anyone interested in a snapshot of studies on particular facilities, both on-street (e.g. bicycle lanes) and off-street (e.g. bicycle parking). The study methodologies varied considerably in type and quality, with few meeting rigorous standards. Secondary data were gathered for 14 case study cities that adopted multiple interventions.
