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.
Participants noted that they faced racism in accessing bike services and in how they were perceived and treated as cyclists (particularly Black men delivering food by bike). The effect of this was to discourage cycling among POC.
Financial barriers included the cost of buying and maintaining a bike, but also a lack of safe bike storage in poorer neighbourhoods and buildings, leading to a fear of theft.
The third barrier was knowledge/information. Participants noted that information about bike sharing and bike services was generally only provided in French, which some immigrants did not speak.
Similarly, information about bike services was provided by news releases and on social media, but one participant stated that the women in her community did not get their information this way, so were unaware of services they would have used.
The final barrier was spacial inequality. The city's subsidized bike share stations were located 6 km from the poorest area of the city. Women noted that they had been harassed while cycling, and some avoided certain central areas of the city where that behaviour is common.
Likewise, one participant noted that when they city asked residents to bike around to identify gaps in cycling infrastructure, only white, older, wealthy residents participated.
These various barriers intersect with each other, just as identities of the participants intersect. For instance, subsidized bikes were available for purchase (financial barrier), but this information wasn't available in many languages (knowledge barrier).
The authors conclude that access to bike infrastructure and services is not simply a question of living close by - there are other significant barriers to cycling for marginalized communities.

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.

sciencedirect.com/science/articl…
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.

Got bored and re-wrote The Charge of the Light Brigade to be about a group of unlucky commuter cyclists. Sincere apologies to Tennyson and my various English professors for the ungodly things I did to the metre to get it to fit into 280 characters...
I
Half a league, half a league,
Half a league onward,
All in the bike lane of Death
Rode the six cyclists.
“Forward, the commuters!
Ride in the lane!” he said.
Into the bike lane of Death
Rode the six cyclists.
II
“Forward, the commuters!”
Was there a one dismayed?
Not though the cyclists knew
The City had blundered.
Theirs not to make reply,
Theirs not to reason why,
Theirs but to do and die.
Into the bike lane of Death
Rode the six cyclists.

With a certain Ratepayers Association back in the news, I thought I'd take a look at the "facts" page on the group's website. #ldnont
Fact 1: Calgary's Supervised Consumption Site ("SCS") led to an increase in crime.

The source for this is, oddly, a letter to the editor to a Barrie newspaper, although there were reports of increased crime near the cite (but see facts 3 and 4 below).
What the Association doesn't note with this fact is that the Calgary SCS prevented 1,055 overdoses, overdose events decreased by 336% due to the SCS's drug safety education, and each $1 spent on an SCS saves the province $5 in other costs.

In light of the #ONPC resolution stating that gender theory is "unscientific," here are a list of resources by medical professionals stating that sex and gender are distinct, and that gender has social aspects. #onpoli #TransRightsAreHumanRights #TransAwarenessWeek
I will also include excerpts from papers showing the link between accepting people's gender and reducing suicide among trans folks. @TGranicAllen's policy will materially contribute to the deaths of transgender people. Please feel free to share this with your MPP.
