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. A couple of articles have already been translated. 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 red paths in the new Korsvägen area design – The visualization image shows distinct red paths on the surface. It really looks like bicycle paths, but this time it is used for the opposite, as paths for pedestrians. The city loses one of its means of expression for road users.
(Korsvägens röda stråk)

New municipal comprehensive plan under consideration – There is a new version of the municipal comprehensive plan for Göteborg open for consideration. The local department of the Swedish cyclists community Cykelfrämjandet has sent in the following statement of opinion, and I was one of the co-writers.
(Ny översiktsplan på remiss)

Rerouting for whom? – How should the signs for reroutings be designed to be easily understood for everybody? I think the signs for cyclists at Korsvägen lack an important key to understanding.
(Omledning för vem?)

The new central town area by bike – There is now a total re-make of the city center of Göteborg going on. But how is the bike commuter network handled in this process?
(Centralenområdet per cykel)

Pedestrians crossing a cyclist flow – Is the flow of 900 cyclists/h along a path a problem for crossing pedestrians? Would it be better to widen the cyclist flow to create an unstructured mix with the pedestrians? What can a one hour flow study tell us about that?
(Korsvägens gc-korsanden)

How well does Göteborg promote bicycling? – Göteborg describes in its website ”För liv och rörelse” how bicycling is promoted in various ways. I comment good and bad things for some of their statements.
(Liv och rörelse med cykel?)

How does the city prioritize bikes? – How seroius will Göteborg be about its new bike commuter network concept? By cherry picking in the different strategy documents, very different answers may be constructed to fit a specific planner’s wishes.
(Hur prioritera cykeln i stan?)

Traffic rules for public squares – Is it allowed to cycle on public squares in Sweden? And do pedestrians have any responsibility to pay attention and adjust to other traffic? Here are answers from the Swedish Transport Agency and my comments to that.
(Trafikregler på torgyta)

The bicycle flows at Korsvägen – My documentation of bicycle flows at a morning rush hour in june 2018. I documented 914 cyclists and their paths.
(Korsvägens cykelströmmar)

More retail apocalypse without bikes? – Can pedestrian and bicycle traffic be the solution to the retail apocalypse? Is this a provocative question? The consulting company Sweco has investigated that instead of just guessing.
(Mer butiksdöd utan cyklar)

How will they fill up the bus? – The public transport organization in western Sweden says in a poster all around Göteborg that a full bus takes away a car queue of 328 m. I discuss a number of problems concerning effectiveness, unbalanced demand, attracting other than car users and the risk of promoting society to get more spread-out.
(Hur ska bussen fyllas?)

Traffic against a red light in Örgryte, Göteborg – Measurement and analysis of how car drivers, cyclists and pedestrians respect yellow and red light.
(Trafik mot Örgryte-rödljus)

Stop light for no reason – For how long are cyclists stopped by red light although the way is free? I measured that throughout “Allén” in Göteborg. Is it possible to reach 20 km/h average speed on the bike commuter lane despite the ineffective traffic lights?
(Rött ljus i onödan)

Cycle or walk against red? – Do the cyclists bother less about red light than pedestrians do? Is it better to walk than to cycle against red? Does the law give free pass to pedestrians? And what is the very purpose of red light?
(Cykla eller gå mot rött?)

Tricked to miss teamworking – This design is really misleading, because to give cyclists and pedestrians a chance to cooperate, it should distinctly show both parties that the other can be expected where their ways actually cross.
(Bortfintat gc-samspel)

How will our regional government reduce CO2 emissions? – They want to reduce the environmental impact of the transport sector by 80 percet until 2030 by promoting car traffic as usual. What?? I am problematizing this.
(Hur ska VGR minska CO2?)

Obstructing long term parked bikes – Short term bike parkings in central Göteborg get filled up with abandoned bikes. The problem, an inventory and solutions are discussed.
(Långparkerade cyklar hindrar)

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?
(Hur fort cyklar folk?)
