Did the Japanese invent Shared Space Streets?


The shared space (or 'naked streets') approach to street design was developed in the Netherlands right? The late Hans Monderman was the pioneering hero who extended it to some surprisingly busy roads and intersections, correct? And it has been popularised and applied in the UK and elsewhere by Ben Hamilton-Baillie, hasn't it?

Or did shared space emerge in Japan?

In a recent Ecohearth post explaining the shared space idea, Dawn Marshallsay includes this sentence:
It could be said that Tokyo led the way, as most of its roads follow the shared-space principle, although they were not purposefully designed to reduce accidents.
Actually, it is mainly small side-streets that are like that, not most roads, but you get the point. Here are some examples photographed during my short visits to Japan. (Scroll down for more discussion after the pictures)

Near Fukuoka airport and a subway station.

Near Tokyo University and Ueno in central Tokyo.
In Nishitokyo City, Tokyo. With a mamachari ('mother bicycle') and kids right on cue to demonstrate the high level of subjective safety here.
Also in Nishitokyo, with another mamachari.
Near Shinjuku, Tokyo (southwest)

Also southwest of Shinjuku.

OK. Let me retreat a little.

I don't really want to take any credit away from Hans Monderman and the other pioneers of today's efforts on Shared Space. Their projects are much more ambitious than these Japanese examples. They extend "public realm" much further into what used to be "traffic space". The side streets of Tokyo and other Japanese cities are not such a challenge to mainstream traffic engineering practice precisely because they are side streets.

Still, it seems a little rough that Hamilton-Baillie fails to mention such Japanese shared space in a June 2010 paper for City Planning Review (pdf), published by the City Planning Institute of Japan.


I suspect Japan deserves a bit more recognition for its little shared-space streets.

What do you think? Are Japanese urban planners, designers and transport planners proud of their side streets? Are they really as successful and safe as they appear to be? Have they been carefully evaluated and researched in Japan?

If you want to see more, try this location then click into street view and explore a little in a shopping district near Ikebukuro station.

  1. I think the Italians invented shared space streets - have you seen Urbino in Le Marche? I am happy to send you a photo.

  2. @Jonathan I am sure you are right, in the sense that medieval streets everywhere were (and often still are) shared spaces. So point taken.

    But notice that these Japanese streets are in many cases relatively modern. Some of them are outside the older (pre-war) 23 Wards area of Tokyo.
    Thanks for the comment and best wishes with your cyclized blogging.

  3. Don't get too excited about Shared Space. I've yet to meet anyone here in the Netherlands who is enthusiastic about it. In fact, there is much criticism of it due to it having lead to a reduction in safety, and especially subjective safety, for cyclists vs. drivers.

    Thankfully, there are very few busy shared space areas, and I'm not aware of any more which are planned. Many villages always were like this, of course, and many still are.

  4. @David Hembrow: Thanks for the comment and for pointing us to your interesting post. Very thought provoking.

    Safety through uncertainty and 'intrigue' seems to be useful to deter recklessness among motorists. But your point is well made that it is uncomfortable (even frightening) for cyclists and some pedestrians. [At least it is a problem above a certain level of traffic density. I gather that bikes and motorists share the streets on small residential streets in the Netherlands without much problem (and with the help of 30 km/h speed restrictions). Is that correct?]

    I wonder if it would be possible to design streets and intersections to get the best of both worlds? In other words, would it be possible to make sure motorists don't feel too secure in their right-of-way but still make vulnerable road users feel high subjective safety?

    In fact, I wonder if even standard Dutch street designs achieve something like that at every intersection, precisely because of the high number of bicycles sailing through?

  5. Paul: In residential streets, cars are excluded except for access. They very rarely allow through traffic. This is an example. Older residential streets which were initially designed as through streets are no longer through streets.

    And cyclists are generally separated at junctions too. Here are some examples of road junctions.

    And here you'll find a video showing what it is like to cycle along a newly renovated street in the Netherlands. You'll see how the junctions work. There's no "sailing through" and just hoping that motorists don't run into you. Cyclists have separate phases at the traffic lights.

    In the smallest streets in the centre of the city, it's a one way system (for cars but not for bikes) designed to make sure you can't go anywhere by car and can't use those streets for through journeys by car. This works much as in residential areas. Very very few cars are seen as people only go there if they need to.

  6. Korea is loaded with just such spaces as in Japan. It seems that the dimensionality of this type space was scaled for the pedestrian user with deliberate intention. This may be so if one considers that much of Seoul (South of the Han) was constructed since the 1960s during which time cars were on the dramatic rise. These are delightful spaces too, I lived on just such a street in Seocho, Seoul, Korea. There were no more than about two dozen cars/day on my street, mostly as deliverers of store goods. Great post and photo documentation

Podcasts on urban mobility and urban issues: a LONG list

Below is my increasingly long list of podcasts on urban mobility and/or urban issues. 

If you are not yet a regular podcast listener, you need to download a podcast-listening app to your phone, tablet or desktop and subscribe (it's free) to the podcasts that interest you.

UPDATE 1: This list has many podcasts but obviously I hope you will try mine! They are Reinventing Transport and Reinventing Parking.

UPDATE 2: I have added THIRTY NINE more since this was first published. Thanks to everyone who has sent tips.

Transport-based City Types and their Trajectories

I want to help you get perspective on your city and its transport system with the help of simple city types based on their dominant transport modes, such as Walking Cities, Transit Cities, Bus Cities, Motorcycle Cities and Car Cities.

This way of thinking about cities is a heuristic (an imperfect mental model or technique that is nevertheless good enough to be helpful). And it obviously is imperfect. For example, real cities often have various modes of transport, and modern cities are really all some kind of hybrid city type.

But it is still useful, especially if we add the idea of a Traffic Saturated City, which is a very different beast from a Car City. It is important for change-makers in Traffic Saturated Cities to be aware they are not in automobile dependent cities yet.

Options for digesting this: 
Read the brief article below and study the diagrams. They complement the podcast. For more depth, LISTEN to the 37 minute audio with the player above. A full transcript of the podcast is…

Singapore Urban Transport: The Warts-and-All Story

Singapore's National Day is this week (9 August). So I decided to share Singapore's urban transport story - or my slightly unusual take on itIt isa unique city in various ways but its urban transport policies are well worth your attention even if you don't live in Singapore.

This is a warts-and-all version of the story, and it is my own view, not any kind of official one.

It's also a little wonkish in parts. [Hi all you policy wonks!]

But I hope to keep your interest with some surprising twists, such as:
Why was the bus-only public transport system in an awful state by the early 1970s?If the buses were awful in early 1974, how was Singapore able to impose drastic increases to the cost of motoring in 1975?You will have guessed that the buses must have been drastically improved in 1974/75. But how was that achieved?Singapore urban transport enjoyed success through the 1980s and 1990s but its core social bargain (cars for the rich; decent but basic public transport for …
