After NYC installed 2,000 speed cameras, crashes fell 30% and injuries 16%.

Outremont residents form human chain to protest bike path’s removal Dozens of community members formed a chain along a bike path in Outremont to protest the Montreal borough’s decision to replace the section for parking spaces.

I was one of the humans in the chain!

(Come and be a link in the next protest. Cars already have enough space in #Montreal: we need to protect our bike lanes, before the new "Ensemble" Montréal administration tears them all out.)

All the bike and pedestrian infrastructure in the world will not do people any good unless a city has an efficient and accountable maintenance plan.

Who will get the joke?

California is closer to Mexico. Join them.

In the Amazon age any BIA not striving for an “experience over expedience” approach is doing its members a disservice.

If only…

The entrance to the 3-storey bike parking garage at Utrecht Central holding 12,500 bicycles. It’s free for the first 24 hours, linked to the station, and used by tens of thousands every day. This is what happens when a country treats bikes as real transport infrastructure, not an afterthought.

This week’s coffee group. Ride a bike, drink coffee.

Riding a bicycle is pretty great any time. Catching an early train back Toronto to ride and meet up with buddies at the weekly coffee spot on the North shore of Lake Ontario is even more great.

Look for them year round Friday mornings at Toronto’s West Humber Park.

Properly designed bike infrastructure doubles as an emergency access lane, allowing first responders to bypass gridlocked car traffic.

This completely nullifies the argument that bike lanes are a safety risk for response times. But it only works if you build them wide enough to be functional.

One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss Copenhagen, the bicycle-friendliest place on the planet, publishes a biannual Bicycle Account, and buried in its pages is a rather astonishing fact.

“One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss.”

“Which means that Copenhagen, a city of 1.2 million people, saves $357 million a year on health costs because something like 80% of its population commutes by bike.” #CityMakingMath

Some costs aren’t costs.

Slide saying “The truth about a city’s aspirations isn’t found in its vision. It’s found in its budget.”

“In my work with cities, one of my messages that resonates most is that the truth about the cities aspirations isn’t found in its plans and visions. It’s found in its budget.

A budget may be the most powerful public policy lever a Council has, and the most authentic one because It reveals so much.”

Just a reminder, the first 5-7 minutes of any winter bike trip will always have you rethinking your choices, but after your body acclimates, you'll begin to reap the rewards of the joy that is winter riding.

We absolutely should. I talked about this at the Illinois Bicycle Summit a few years ago. This would make a real difference and would likely enlist the insurance industry in making drivers safer to protect their bottom line.

@camguthrie City of #Guelph. A model for Guelph to follow. Two helpful points for you:
1) it gets plowed of snow
2) the lanes don’t disappear at intersections to veer into the sidewalk and run through bus stop shelters in order to make room for left turn lanes.

The Harbord streetscape is a dreamscape. Well done #topoli - this is a model for how to make better, safer neighborhoods. #biketo #walkto #toronto #cycling #urbanism

This is the greatest story ever told:

A person in Hamilton, ON stole a city bus and then proceeded to make the stops along the way, allowing passengers to board and exit freely. The person actually refusing someone looking to board with an expired pass. 🔥🔥

Screenshot of a tweet from Joyce Carol Oates posted on Sunday, November 9th that reads "so curious that such a wealthy man never posts anything that indicates that he enjoys or is even aware of what virtually everyone appreciates--scenes from nature, pet dog or cat, praise for a movie, music, a book (but doubt that he reads); pride in a friend's or relative's accomplishment; condolences for someone who has died; pleasure in sports, acclaim for a favorite team; references to history. in fact he seems totally uneducated, uncultured. the poorest persons on Twitter may have access to more beauty & meaning in life than the "most wealthy person in the world."

Found the tweet that Joyce Carol Oates bodied Elon Musk with and it's so beautiful in its eloquent, simple take down. So much so he's crashing out trying to prove he reads books now. Put this in the Louvre.

So many days in January and February where we drag our batteries inside for the night and put them on a charger.

Cars might work fine in California or Florida, but they’re not practical here in Canada. We have winter.

Reducing car use in urban areas a “very significant road safety tool” — RSA-funded research Reducing car use in urban areas is a "very significant road safety tool", while pedestrian priority has "very significant potential" for safety in our villages, towns, and cities, according to TU Dublin researchers in work which was funded by the Road Safety Authority. Researchers from TU Dublin examined the outcomes of traffic changes in Oslo in Norway, smaller urban areas in the Pontevedra region in Spain, Brussels, and Ghent in Belgium.

The average US taxpayer spends $36 a year on SNAP

You know what they spend on corporate subsidies? $670

Poor and disabled people who need food are not the problem

If you’re angry about “your money” feeding people but not angry it’s giving tax cuts to the wealthy?

You’re doing their dirty work.

Twenty years ago I lived in an island community. There a coalition of right- wing, farmers miffed that their neighbour was getting a few tower leases and they weren’t AND almost all the hippies on the island (can we say lefties by definition?) combined to nearly stop our wind farm.

You’ve officially reached the, “L'État, c'est moi” stage of political maturity.

Best advice.
