English index

The name Trafikistan is Swedish, meaning traffic in the city. My articles are mainly about how the city works for cyclists, how different road users behave and cooperate, how good and bad design affects behavior, and about laws and our relation to them.

All articles are written in Swedish, but below I have started to create an index with very brief descriptions in English for some articles. If I get requests, I may try to translate some articles and make the translations available through their english titles on this page. You are also welcome to point out things that can make my English translations better. No reader is helped by wrong terms or bad text flow.

You can reach me either in the comment fields, or else …

The good rerouting at Sprängkullen – A good temporary bikeway in Göteborg uses a complete car lane. Such bike priority is otherwise only seen in the Netherlands. And the contractor shows great interest in listening to problems reported by cyclists.
(Sprängkullens bra omledning)

The enduro trail at Vasagatan – A constant flickering of surface materials on the bikeway warns for everything and nothing. It shakes bikes into pieces and makes cyclists concentrate only on their own business. And the design doesn’t tell pedestrians that they are crossing a bikeway. These are effective obstacles for teamwork.
(Vasagatans endurobana)

Advertisement can cause bike-pedestrian collisions – Advertising signs really want to attract attention, but that can make them hide road users for each other. Here is an example where I was a hairbreadth from a collision. People tend to think that what you see is all there is.
(Reklam för GC-kollision)

Biking in New York City – Interesting and positive experience from my biking in Manhattan.
(Cykla i New York City)

Test the width needed for bike overtaking bike! – How wide does a bikeway need to be to allow cyclists to overtake each other? Here is an excellent place where you can test this irl!
(Testa omkörningsbredden!)

Compose symbols on signs carefully – The orientation and grouping of symbols on a sign may cooperate or counteract with the message they are supposed to convey.
(Vänd cykelsymbolen rätt)

What is good separation between cyclists and pedestrians? – My digging into the problem of how different separation design can work, and why.
(Vad är bra gc-separering?)

A bikeway in raking light – The car headlights give us a raking light on the bikeway and reveals substantial irregularities. This gives us also an indication of how they were created.
(En cykelbana i släpljus)

All have to cooperate – The traffic designers, the law and the police must join hands with the road users. And this cooperation must be built on knowledge in psychology and social forces. So don’t just let down the road users, asking them to fix problems induced by the other participants.
(Alla behöver samspela)

Prevent eternal red light – Prioritizing public transport can steal all green light periods from cyclists that want to cross. There must be a limit for how many traffic light cycles that cyclists can be forced to wait.
(Förhindra evigt rödljus)

The power of our unconscious – A number of researchers explain how much of what we are doing that is actually unconscious and automatic rather than based on rational considerations. Our traffic environment is not always designed with this in mind. Designers rely too much on our rational reasoning.
(Kraften i det omedvetna)

How fast do people bike? – I have measured the speed of 155 cyclists and 54 pedestrians where there was plenty of room for both. People walk in 5-6 km/h but bike in 15-30 km/h. That’s a large difference between pedestrians and cyclists, but also a large difference within the cyclists group. And is a bike passing at 30 km/h seen as dangerous for pedestrians but not a car doing the same?
