Desire Lines ‘Defined’
• 100 year old urban planning term
• Show where people naturally desire to walk
• A perfect expression of human natural purpose
• Great design pattern for path design (Christopher Alexander)
• A little known concept / term
• Misused concept by modern planners

Have Urban Planners Lost the Plot?

BANKS’ CAR HIT BY BOLLARDS
4 October 2002
ENGLAND football hero Gordon Banks escaped injury when the car he was travelling in was impaled on rising bollards in Cambridge City Centre.
...the chauffeur says he will now sue Cambridge County Council for writing off his Mercedes.
A bollard pushed the Mercedes’ engine up through the bonnet, spilling hot oil across the road. He said, “My passengers were badly shaken, Mr Banks bumped his head.”
BOLLARDS CLAIM SECOND VICTIM IN 24 HOURS
18 October 2002
THE rising bollards on Cambridge’s Emmanuel Road have claimed a second victim in a 24-hour period.
A woman drove into the bollards at 2.20pm yesterday and complained of chest pains after the collision.
...County Council Engineers had to repair the damage from that incident, estimated at £600-£700...
Richard Preston, the council’s project manager, said there were no plans to put up more signs.
He said: “If people can miss six or seven signs, then they could miss nine or 10. In a lot of these incidents people are failing to look at any sign.”
“We are aware of a higher frequency of incidents of late.”
‘WHAT A LOAD OF BOLLARDS!’
18 June 2003
CAMBRIDGE’S notorious rising bollards have been given a top award by eurocrats in Brussels.
The traffic calming measures have claimed dozens of victims in the four years since they were installed.
Coun Shona Johnstone, the county council’s lead member for the environment and transport, said: “The accidents are getting less frequent. I think they deserve an award. They were controversial in the past but people have got used to them and can now see what the benefits are”
“Sue Hewitt, who manages the bollards for Cambridge County Council, admitted she was concerned at the number of accidents at the spot, but insisted drivers were to blame.” (Cambridge Evening News, 9/8/2001)
Rising Bollards – drivers to blame!

Susie Haywood, a spokesman, said: "The Government and the partnerships have an exceptionally long way to go to win the hearts and minds of motorists that cameras work to save lives and not just to make their wallets lighter."

household fire
– Cookers left unattended – 75% of incidents

Natural SelectionDesire Lines show us ‘tracks’ left by natural human interactions
Perhaps design evolution has parallels with natural evolution
Capitalist economies arguably draw parallels with nature, maybe contributing to the commercial success of one design over another via natural selection
38
Natural Selection
Focus on Desire Lines, and adapting designs in accordance with what we learn from them should lead to successful adaption
Survival of the fittest adaptions in the commercial context will perhaps become ever more evident
Who focuses on ‘desire lines’ now? Amazon, Microsoft, Apple, Google, Virgin, Smile – how are they doing?
39
Natural Selection
Actually, why Darwin?
Don has provided us with a lens to focus our observations of people interacting with things
And terms to describe elements of those things, eg. ‘Affordance’
(And has inspired many of us to work in this field)
If our focus on people’s natural interactions with things, and our emotional responses, leads to designs evolving in the right direction, perhaps we should call this...
Normanian Natural Selection !!?

Finally...
‘Desire Lines’ (the extended version) is a memorable concept reminding us about feedback
There is no rocket science here but most companies are not paying attention to this – WHY?
Even when desire lines speak of very serious consequences we still have a tendency to say ‘stupid user’ and not look to the design – WHY?
41
Finally...
Smart, successful companies ARE paying attention to desire lines. But, typically in economics, such success factors are quickly copied – why is this not the case here?
Maybe it’s time for other companies to wise up and get on the right side of ‘Normanian Natural Selection’, for commercial advantage (!)
