I am by no means trying to suggest that we give up as you say modeling their performance with the planner’s ample and absolutely vital technical toolkit. But no, I very much believe that in light of the evidence motorized two and three wheelers do need to be singled out for special attention given our significant ignorance and demonstrated inability to cope. To my mind we are right in the middle here of the politics of transport, behind which there must be a sound vision and understanding. Which by all indications is greatly lacking today.   Eric Britton   PS. As in all these exchanges Eric, I do not want me to be right. I want US to be right.     <div style='border:none;border-bottom:solid windowtext 1.0pt;padding:0cm 0cm 1.0pt 0cm'>   </div>   -----Original Message----- From: Eric Bruun [mailto:ericbruun@earthlink.net] Sent: Monday, September 11, 2006 11:23 PM To: eric.britton@ecoplan.org; Global 'South' Sustainable Transport Subject: Re: Motorcycles as separate studies   Eric Britton   I don't agree with the approach of segregating motorcycles from other urban transport issues, unless they have to do with technology or some specific aspect. Motorcycles should be analyzed as part of the transportation network. They have to be modeled along with autos, bicycles and public transport to see how mode choice and mode split are influenced by changes in circumstances. Historically they have been treated only as a safety problem not as a transportation mode. Eric Bruun     </div> </body> </html>
