MINI LECTURE: Urban structure and mobility behavior

[1/12]
If you have ever heard people saying: ‘cycling cannot work here! Our city is much bigger than Amsterdam!!1!’

🧵👇👇
[2/12]
The City of Amsterdam is a central part of a much larger daily urban system.

The Amsterdam Metropolitan Region (@MRAsamenwerking ) spans 2.580 km2 and houses 2.5 million people.
This includes @Schiphol, @Lelystad, @almere, @ZandvoortaanZee.
[3/12]
A whopping 47% of ALL TRIPS from/to/within the region are made by foot 🚶 or by bicycle 🚲.

[4/12]
So cycling/walking do not stop at the border of Amsterdam city center or at the built-up area.

They count for almost half of all trips for this entire region of 2.5 million people. So, how does THAT compare?
[5/12]
We can drag and drop this area to other metropolitan areas.

Here, we overlay it on Mexico City. With 8.8 million inhabitants it offers a much higher average density on roughly the same area.

Not similar, sure. But certainly comparable:
🇬🇧 London: 9 million inhabitants
🇫🇷 Paris: 2.1 million inhabitants
🇺🇸 Atlanta: 5.6 million inhabitants
🇦🇺 Sydney: 5.3 million inhabitants
[7/12]
Many urban areas are similar in size and have higher population densities (better conditions for cycling).

Yes, we can discuss differences. But what CAN we learn from this? Why does cycling/walking work on this larger scale?
[8/12]
One reason is that most trips (BY FAR) are local. To go to school 🏫, shopping 🛒, visiting 👩‍❤️‍💋‍👨.

We tend to focus on long distance trips, due to our mainstream mobility narrative. See: coursera.org/learn/alternat…)

If we zoom in, that is what we see here as well. Walking 🚶 and cycling 🚲 accounts for 64% (‼) of all local trips!

This is where the large potential lies for other cities as well!

As @FrauKrone keeps saying: “it is the infrastructure, stupid”

Instead of bicycle highways, this means we should focus first on creating local safe infrastructure. That’s where it can really count!

But that's not all...
[11/12]
Very few people cycle large distances between cities throughout the region.

For those trips many combine cycling with the high-quality transit services of @NS_online. Most people have a high number of trains 🚃 within cycling distance.

Cycling + transit creates synergies: combining door-to-door flexibility with high speed and high capacity outperforms the car on most relations in the region.

A system that can successfully break car-dependency in any context!

MINI LECTURE [1/16]

How do we frame systemic traffic violence: As glitches in the machine or as unacceptable human tragedies?

Based on the Open Access paper: sciencedirect.com/science/articl…
(pic via @EdwardLamb)
[2/16]

Traffic violence represents the largest threat to life and limb that most people in contemporary, car-based society experience on a daily basis in public space.

(statistics of @WHO)
[3/16]

With this magnitude of violence and relatively limited attention it receives, we seem to have collectively accepted it as a tolerable price for our car-based society.

MINI LECTURE: Street appropriation [1/13]

Cars have taken over our public space. That APPROPRIATION happens in stealth. Government responses to it seem a-political and technocratic. This hides a 1-directional process that should be highly politicised.

Case: BLOKKENWEG (Ede 🇳🇱)
[2/13]

The BLOKKENWEG parallels the train tracks between Utrecht (to the west) and Arnhem (to the east).

It links directly to an important railway crossing for traveling between Ede-South and Ede center. The street and tracks are separated by public allotments since the 1980s.
[3/13]

Built in the 1920s, it was part of a small garden-city district for workers of the ENKA factory. The houses, meant for white-collar workers, were relatively large. Originally, the street was a gravel road with a dedicated walking path.

Cars where almost non-existent.

Adapting streets to a "six-foot-city" is certainly a question of geometry & space, but also how to govern that space, how to develop capacity to deliver #humanscale networks.
3 principles explored in our latest commentary bit.ly/3h6bkWZ
Photo: @dutch_ish Image
Principle 1 for #humanscale streets: leverage #accessibility to meaningful destinations. Entire street networks that offer a range of mobility options need to be realized. bit.ly/3h6bkWZ Image
Principle 2 for #humanscale streets: Empower #local policy networks to nurture public and political support for improved accessibility at the human scale. #citizenscience #datadriven #CommunityEngagement

[1] Iedere schooldag vinden er in NL gemiddeld 17 verkeersongevallen plaats rondom scholen waar politie aan te pas komt.

We kunnen dat verkeersgeweld aanpakken. Maar @VeiligVerkeer hangt liever elk jaar wat spandoekjes op: "De scholen zijn weer begonnen"
nrc.nl/nieuws/2020/08…
[2] We zijn gewend geraakt om systematisch verkeersgeweld te zien als onvermijdelijk gevolg van onze mobiliteit.

Dan is het logisch om mensen te leren er mee om te gaan, i.p.v. het op te lossen. Maar wat als we dat geweld op straat niet voor lief nemen?
decorrespondent.nl/11507/loopt-he… Image
[3] Sinds de opkomst van de auto is daar strijd over geleverd: is het nieuwe geweld moreel onacceptabel of een nare statistische bijkomstigheid.

Het morele standpunt werd echter 𝘬𝘢𝘭𝘵𝘨𝘦𝘴𝘵𝘦𝘭𝘭𝘵. En zo werd het debat gedepolitiseerd.

'Who caused the accident?' is a question often used to avoid asking 'What allowed the accident to be so destructive?' (@mrendell) Image
Unbelievable! While car-makers are flooding our streets with increasingly lethal products, we focus our policies on disciplining 'distracted pedestrians an cyclists'. Image
[3] 'It is not the car that kills, but the erronous driver'

If that happens over 1.2 million times annually (20-fold if we count severe injuries) it is SYSTEMIC in its design.

Humans are fallible, so be wary of providing them with destructive tools that assume they are not. Image
