There aren’t many peo­ple, I believe, who are able to drive and who are not inter­ested in traf­fic dynam­ics. Jonah Lehrer, in a recent col­umn for Seed, takes a brief look at traf­fic psy­chol­ogy; includ­ing ‘the com­muters para­dox’ and the ‘crit­i­cal den­sity’.

They found that, when peo­ple are choos­ing where to live, they con­sis­tently under­es­ti­mate the pain of a long com­mute. This leads peo­ple to mis­tak­enly believe that the McMan­sion in the sub­urbs, with its extra bed­room and sprawl­ing lawn, will make them hap­pier, even though it might force them to drive an addi­tional forty-five min­utes to work. It turns out, how­ever, that traf­fic is tor­ture, and the big house isn’t worth it. Accord­ing to the cal­cu­la­tions of Frey and Stutzer, a per­son with a one-hour com­mute has to earn 40 per­cent more money to be as sat­is­fied with life as some­one who walks to the office.

Appar­ently, the rea­son we dis­like com­mutes so much is because “the flow of traf­fic is inher­ently unpredictable”–once on the roads we are at the mercy of the traf­fic all around us.

For more infor­ma­tion on this topic, William Beaty’s Traf­fic Waves site is full of inter­est­ing the­o­ries and obser­va­tions on traf­fic ‘physics’. Lehrer sug­gests Tom Vanderbilt’s Traf­fic–a book I’ve seen rec­om­mended many times.
