Cycling safety is a concern, especially at multiuse trail-road intersections. Crowdsourced data reveals these junctions have more collisions and injuries than road-road intersections, highlighting design needs.

Area of Science:

Urban planning
Transportation engineering
Public health

Background:

Cycling safety concerns deter ridership.
Multiuse trails are preferred but lack collision data.
Underreporting is a significant issue for safety analysis.

Purpose of the Study:

Identify design characteristics of unsafe multiuse trail-road intersections.
Compare incident rates at multiuse trail-road vs. road-road intersections.
Inform infrastructure improvements for cyclist safety.

Main Methods:

Utilized crowdsourced cycling incident data (BikeMaps.org, 2005-2016).
Analyzed collisions and near misses at intersections.
Conducted site observations at 32 multiuse trail-road intersections.

Keywords:

Collision Crowdsource Cycling Multiuse trail Near miss Safety

Related Experiment Videos

Employed negative binomial regression for analysis.

Main Results:

Multiuse trail-road intersections had a higher collision proportion (38%) than road-road intersections (23%).
Injuries were more frequent at multiuse trail-road intersections (33% vs. 15%).
Cycling volume, vehicle volume, and trail sight distance correlated with incident frequency.

Conclusions:

Crowdsourced data enhances understanding of cycling safety at trail-road crossings.
Specific infrastructure characteristics influence incident frequency.
Addressing these intersections is crucial for improving cyclist safety and ridership.
