On-road bicycle facilities and bicycle crashes in Iowa, 2007–2010.

This reserach examined the impact of on-road bicycle facilities on crash risk. The results suggest that intersections with an on-road bicycle facility are more protective against crashes than those without, that bicycle-specific pavement markings are more protective against crashes than bicycle signage and that increased street width increases the risk of a bicycle-motor vehicle crash.

Review of cycling safety policies in the European Union

This report details best practices for facilitating cycling on roadways in a variety of European Union cities. It investigates policy, infrastructure, vehicle design and road user behaviour interventions and makes a series of recommendations to the EU and its members states.

Evaluation of the C-roundabout for cyclists

This report evaluates the on-site operation of the C-roundabout design at a site in Auckland, New Zealand. The primary aim of the C-roundabout is to improve the safety of cyclists at multi-lane roundabouts and make multi-lane roundabouts more cyclist-friendly. The concept of the design is to decrease vehicle speeds through the roundabout to around 30 km/hr by increasing the deflection of the roundabout, and to reduce the widths of approach lanes and circulating lanes so that cyclists are required to travel in the centre of the lanes, like other vehicles.

Evaluation of narrow bridge treatments for cyclist safety

This report examines the effectiveness of treatments on narrow bridges to improve the safety of bicycle riders. The project tested the use of ‘Watch for Bicycles’ signs, ‘No Overtaking on Bridge’ signs, and Bicycle Awareness Zone (BAZ) pavement symbols. The findings recommend changes to the Australian guidelines relating to narrow bridge treatments for cyclists.

Evaluation of counter-flow cycling in one-way streets in Oslo city centre

This study evaluated the effects of counter flow cycling in one way streets on the behaviour, comfort, perceptions of safety and ease of access of pedestrians, cyclists and car drivers. The study also considered the safety consequences of this measure.

Route Infrastructure and the Risk of Injuries to Bicyclists: A Case-Crossover Study

This Canadian research,published in the American Journal of Public Health in October 2012, compared cycling injury risks of 14 route types. It found that separated bike lanes were the safest, with an estimated relative risk of 0.1 (or a reduction in injury risk of about 90%). Other routes designed for bikes were also safer, with relative risks near 0.5 (or a reduction in injury risk of about 50%): painted bike lanes on major streets without any parked cars; residential street bike routes; and bike paths in parks.

High rate of crashes at roundabouts involving cyclists may be reduced

This paper considers the high rate of roundabout crashes involving cyclists and suggests design changes which could be used to reduce such crashes, particularly at inner urban roundabouts.

What do cyclists need to see to avoid single-bicycle crashes?

This research paper, published in the journal Ergonomics in 2011, indicates that crashes, in which the cyclist collided with a bollard or road narrowing or rode off the road, were related to the visual characteristics of bicycle facilities. Edge markings, especially in curves of bicycle tracks, and improved conspicuity of bollards are recommended.

Bicyclists’ Injuries and the Cycling Environment

This University of British Columbia Cycling in Cities study examined the association between bicyclists’ injuries and the cycling environment (e.g., route types, intersection types).  It found that the lower risks on quiet streets and on busy streets with bike-specific infrastructure support the route-design approach used in many northern European countries. Transportation infrastructure with lower bicycling injury risks merits public health support to reduce injuries and promote cycling.

A technical evaluation of bicycle carriage on Victorian trains and coaches

This study investigates practical ways to carry bicycles on regional public transport in Victoria, in order to create a more integrated transport system.
