Countermeasures
Countermeasures to improve bicycle safety are listed in the table below and discussed individually in the remainder of this chapter. The table is intended to provide a rough estimate of each countermeasure’s effectiveness, use, cost, and time required for implementation. Effectiveness is shown using a five-star rating system.
- Countermeasures that receive or have been determined to be effective.
- Countermeasures that receive are considered promising, and likely to be effective.
- Countermeasures that receive ✩ or ✩✩ have NOT been determined to be effective, either because there has been limited or no high-quality evidence (✩) or because effectiveness is still undetermined based on the available evidence (✩✩).
States, communities, and other organizations are encouraged to use , and especially or , countermeasures. They should use caution in selecting ✩ or ✩✩ countermeasures, since conclusive evidence is not available to demonstrate the effectiveness of these countermeasures. If they decide to use a new or emerging countermeasure that has not yet been studied sufficiently to demonstrate that the countermeasure is effective, they are encouraged to have the countermeasure evaluated in connection with its use.
Further details about the symbols and terms used are included after the table. Effectiveness, cost, and time to implement can vary substantially from State to State and community to community. Costs for many countermeasures are difficult to measure, so the summary terms are very approximate. See each countermeasure discussion for more information.
Each countermeasure to improve bicycle safety is discussed individually in this chapter. Full descriptions are included for , and countermeasures. Brief descriptions are included for ✩ and ✩✩ countermeasures. Further details about the ✩ and ✩✩ countermeasures are included in Appendix A9 to this report.

Effectiveness: |
