This #CyclingScienceSunday let's look at whether drivers look for cyclists while making turns.

TL;DR: Approximately half of drivers don't look for cyclists, even while turning across a bike lane.

The authors used an eye-tracking headset with 19 participants who drove a set route in a retail/residential area of Toronto. The route included two turns off a major road with a bike lane (Bloor St.) onto other roads. Image
Turn 1 had a painted bike lane, while Turn 2 had a lane separated by parked cars that had a median with a bollard at the intersection. The parking ended 10m before the intersection. Image

This #CyclingScienceSunday let's look at some things that prevent marginalized communities from biking, even where there is good infrastructure. 🧵

TL;DR: Racism, financial barriers, knowledge barriers, and spatial inequality.

This study comes from Grenoble, France, which is a cycling-friendly city. The authors did 19 interviews with policymakers, residents with different identities, and bike service providers to identify barriers to cycling for people from marginalized communities.
From these interviews, the authors identified four main barriers to cycling: racism, financial barriers, information or knowledge barriers, and spatial inequalities.

Today for #CyclingScienceSunday we're taking a look at the effect low-traffic neighbourhoods ("LTNs") have on car ownership.

TL;DR: Over 2 years, LTNs decrease car ownership by 6%, and cycle tracks decrease car ownership by 2%.

The authors (@RachelAldred, @Urban_Turbo and Anna Goodman who I can't find on twitter), looked at car registration data from 2015-2019 to determine whether LTNs and other cycling infrastructure built in London, England impacted car ownership compared to other areas in the city.
Two years after a low-traffic neighbourhood was built, car ownership in that area had decreased by 6% (23 cars/vans per 1000) relative to other areas of the city. Likewise, where cycle tracks were built, car ownership decreased by 2% (7 cars/vans per 1000).

In light of all the bad news for pedestrians and cyclists this week, this #CyclingScienceSunday let's look at how news coverage of crashes affects perceptions of pedestrians.

TL;DR: people are hit by drivers, not cars. @ your favourite journalist.

sciencedirect.com/science/articl…
The authors wrote three versions of a news article about a collision: a pedestrian-focused, a driver-focused and a thematically-framed (i.e., putting the crash in the context of other similar crashes) version.
Around 1000 people were given one of these versions to read, and then were asked a series of questions about who was to blame, what the punishment should be, and how to improve safety.

This #CyclingScienceSunday let's take a look at what factors prompt people to bike in the winter.

TL;DR: It mostly comes down to plowing bike lanes. If bike lanes are plowed, 40% of people say they would bike in the winter.

This study is from Sweden, which has a pretty robust cycling culture (although the study is 20 years old and it was a bit different then). The authors differentiated between people who frequently bike in the winter, don't bike in the winter, infrequently bike or never bike.
Study participants were asked to rank the importance of factors influencing what mode of transport they took.

Those who biked in summer but not in winter rated precipitation, road condition and temperature as the most significant reasons for not choosing bikes in the winter.
