"Use bicycle bell!" Lund's solution to their own horrendous planning. Four lanes for cars. Cyclists surely sort out who'll get the first try to not get stuck in the fence with their handlebars. Pedestrians are expected to dissolve. In which way exactly does the bicycle bell help here?

De skriver: "Cyklist-beteendet som gör bilister vansinniga". Detta förvränger budskapet totalt, polariserar och har inget att göra med vad enkäten gick ut på. Så dåligt!

One almost wonders which transport mode has an engine. One of a thousand examples where bikes cover more altitude than cars. And often there are steep ramps. But hey, we're cycling for exercise, right?

Bikes on trains in Sweden, episode 443765. Two more wanted to get on. Would have been easy any other time. This time conductor refused on a whim, saying max one more. Next train cancelled. One hour to next train after that. Sustainable travel in Sweden, just forget it.

The host in Lucca, IT, defaulted to thinking that travelling means flying or driving a car. When I took the train and rode my bike. And walked, of course.

Spending a few days in the theoretically beautiful city of Lucca, Italy, and all I see is how cars ruin everything. It becomes so blatantly obvious in a place built before they existed to which lengths we go to accommodate them at the cost of everything else.

This is why I find the illustration by Karl Jilg incorrect. It implies that the situation is up to you - if you don't step into the abyss, you're fine (yes, no railings or anything, but still within your control). But you're not fine wherever cars can come flying - like here at a bus stop.

Glare in traffic is debated from a driver's perspective, but what about cyclists and pedestrians? We applied for research funding on the topic. What is your opinion? Is it a problem? Under which circumstances? Has it changed over time? What should be done? What is cycling/walking specific? ...

Another example of Sweden (not) taking care of its active road users. This path runs parallel with a major ring road. I wasn't the only one pushing my bike here, walking in the snow, and it requires a bit for me to give in to this. Accessibility, one of the national transport goals ...

No, Sweden is not the country where the bike/walking infrastructure is cleared better than the streets. Didn't have to go out of my way to find those spots. It's standard. Roads weren't great either, but no issues with a car. Saw people with a wheelchair, they had trouble getting through.

When your gym asks you to sort plastic bottles, because they ❤️ the environment, and at the same time let people coming by bike subsidise car drivers' parking. While not even providing any proper bike parking. Carbrain forever.

This year I was inside of a car five times, for two of those occasions I was driving, one of those for work. Yes, I'm priviliged, living close to most things I need, have grown-up kids, ok public transport and a willingness to bike also longer distances. But many people have a similar situation.

First grit flat of the season. In 2024 we should be able to do better? As soon as grit season starts I avoid cycle paths even more than I usually do, but hard to do so 100 %. Luckily I fix my flats myself, so it's only an annoyance, but keep thinking of those who can't. Proper barrier, this grit.

Last night someone stole my bike that had been with me for half of my life. It had been my go-to town bike for a long time, and during the recent years my son used it. I hope it'll find its way back somehow, but if not - ride on, wherever you are!

Yes, then again, when you do overnighters here in summer, it almost doesn't get dark. But the bigger challenge with longer rides in winter is the cold, and snow and ice on the roads. Darkness can easily be handled with good lights. Including a pic from Monday ca 6 pm and -4 deg C.

My hypothesis is that these white lines make motorists pass pedestrians and cyclists closer than they would without the lines. There's so much wrong with this, I don't even know where to start.
November 2, 2024 at 5:47 PM
Just in case anyone still thinks that so-called cycling infrastructure is made for cyclists and not for clearing the way for motorists. Two random examples of a systematic practice.

We recommend motorists to overtake cyclists as if they were cars - with a full lane change or corresponding manoeuvre. Find the scientific evidence in our report (in Swedish): www.diva-portal.org/smash/get/di...

Just finished reading this important book. Recommend it to everyone. I had no idea just how all-encompassing the impact of roads and traffic is on nature, wildlife and, of course, us humans. Read it!
