I strongly believe in platform screen doors in Metros, but nearly all literature around it is WHY it should be installed. but it is the HOW that realizes the dream, and I stuffed this post with as much history and details as I can to help visualize how such a thing can be realized

When Seoul's courts sided with Yoon Byung-so, a widower who had lost his wife due to a platform incident, they set a precedent:

If someone falls off a platform and loses their life due to a train, whether intentionally or not, the railway operator does bear some responsibility for their death.

How Seoul Metro Installed Platform Screen Doors Everywhere The political history of a safety equipment

Platform screen doors (PSDs) in Seoul were fundamentally a political issue. Once political support was secured, financial and engineering barriers quickly gave way.

Loved this piece by @seung.bsky.social explaining how 200+ stations received PSDs in <10 years.

Meanwhile for Douglas St in Downtown Victoria, with over 60 buses per direction per hour during peaks, it's taken a decade for planning work to actually start, a year for a lackluster 10%-conceptual design to show up, and likely will take years longer for anything to happen. We can do better.

Graph of Average Annual Cost of Housing and Transportation in Metro Vancouver by Municipality

Metro Vancouver can't solve cost-of-living crisis without addressing the cost of getting around

While the multi-billion-dollar SkyTrain projects draw the most public attention β€” and money β€” there’s another, often overlooked mode of transportation that Metro’s leaders view as a big part of the near-term solution: the humble bus.

It's no surprise that housing in Metro Vancouver is expensive. But it might surprise you that for some parts of our region, transportation costs even more than housing.

Opinion: Why this TransLink bus exchange in Surrey needs to be relocated | Urbanized TransLink's Scottsdale bus exchange at Strawberry Hill Shopping Centre in Surrey needs to be relocated to a more accessible, central site.

In 2023, Scottsdale bus exchange 🚌 outperformed 30 SkyTrain stations πŸš‡ in weekday boardings. By relocating it to the heart of the community and building transit-oriented housing, Surrey can unlock even greater potential for both transit and the people it serves.

Biked through North Delta again today and I'm still baffled at the number of maze gates they put everywhere on bike routes. Does someone's cousin own a company that makes maze gates or something? Even the railways don't use so many.

Opinion: Here are six North Shore traffic fixes we can implement now While the idea of creating a third crossing is getting a lot of buzz, here are some other options that could be implemented quickly to improve transit and help with congestion

"If a third crossing were to connect to the North Shore, where would the 19,000 vehicles per lane each day go? Will Marine Drive be widened for them? East Keith Road? Grand Blvd? What should be demolished to widen those corridors?"

22) β€œthe Canada Line is Under-built”

The Canada Line is not even half full to design capacity. Given recent outcomes the spirit of economy guiding Canada Line engineering is quite underrated

For average boardings per revenue hour, the 3, 20, and 5/6 trolleys are in the top 25. No trolleys appear in the top 25 for capacity utilization, while the 3, 20, and 8 trolleys are in the top 25 for (lowest) cost per boarded passenger.

Some Vancouver bus routes are notably missing from the podium, partially due to services being reallocated elsewhere to address overcrowding. In turn, reduced frequency plays a role in making transit less desirable for riders.

In 2012, @translink.ca released some analysis showing what characteristics are common to the most successful bus routes in Metro Vancouver. I applied that methodology for 2024, and many of the attributes still hold true.

Most North American cities: we should allow cars to overtake buses at stops at any cost. Traffic MUST FLOW!

Great transit cities: we should systematically prevent cars from overtaking stopped buses with median curbs because it's a hazard for alighting passengers and it delays buses.

Why Ottawa's Buses are Always Late

Great video by @casualcommuter.bsky.social on how OC Transpo got so unreliable.

Most important point to me is that good public transit can save people money in the long run.

I made a map of population density (CSDs) in BC overlaid with the highway network, the potential of intercity public transit is much stronger than you might expect!

Metropolis did a good thing! They conceded the crosswalk between the bus loop and the SkyTrain Station to people, and blocked it to cars turning right out of the mall parkade. Kudos to them.

Despite its flaws, I still think the O-Train is a great system and will become even better with the extensions. I hope the technical challenges are overcome soon and that funding is established to fix some of the issues highlighted above.

Thank you / merci Ottawa!

- Closing Line 2 for 4 years’ worth of upgrades while still keeping single-track portions, not adding electrification, and mandating two transfers from the airport to the city centre are all questionable decisions that will likely come back to haunt the line as it becomes more popular

- The curves near Hurdman station are really unpleasant. Lots of rail screeching at a painfully slow speed. Is this causing the bogie issues? IDK but it feels unnecessary, since the station could've been moved while extending the Transitway to meet it, rather than forcing the sharp curves

The Ugly πŸ’€

- Despite being only 5 years old, the O-Train is out of service fairly regularly for maintenance befitting a much older system. Beyond scheduled outages, I had the misfortune of being on the train when something went wrong in the eastern end, forcing a shuttle service
