The U.K.’s Transport Research Laboratory (TRL) released a report highlighting existing research on the role of infrastructure in relation to the safety of cyclists and their interaction with other road users. The report consists of an international literature review of this subject and was undertaken as part of the wider research program, Road User Safety and Cycling, being led by TRL. The paper identifies the influence of infrastructure on intermediate, behavioral outcomes which, in turn, may influence accident risk, such as the speed of motorized traffic and cyclist route choice and maneuvers, etc.
The study finds that, of all interventions to increase bicyclist safety, the greatest benefits result from reduction in the general speed of motorized traffic. According to the report, speed reduction may be achieved through a variety of methods including physical traffic calming; urban design that changes the appearance and the (pedestrian) use of a street; and, possibly, the wider use of 20 mph speed limits, which are common in some cities.
