Unfortunately the final report available on the web on density does not have the cyclist map. http://www.lse.ac.uk/collections/cities/pdf/LSEDensityReport.pdf See below FYI ________________________________________ Alain Chiaradia GradDipl (AA) Arch dplg Director SPACE SYNTAX ________________________________________ -----Original Message----- From: S. N.C. Dalton [mailto:[log in to unmask]] Sent: 20 September 2007 10:47 To: [log in to unmask] Subject: Re: [SPACESYNTAX] the use of number - 2 Even when the landscape is relatively flat poor design create problems 'The Milton Keynes redway system is a 200km network of cycleways/ paths for cyclists and pedestrians in Milton Keynes, England. It is generally surfaced with red tarmac, and criss-crosses most of the city. The system is popular with leisure cyclists though not with "serious" cyclists... Using the redways can be frustrating for experienced cyclists, because they tend to go under or over the roads, rather than vice versa. The frequent changes in gradient, and circuitious routing, can be tiring, demanding on cycle and cyclist, and lead to slow journey times..." (http://en.wikipedia.org/wiki/ Milton_Keynes_redway_system) I have red a number of ( now slightly old ) guides on cycle land construction and you only get a odd nod or wink to gradient during the design. What I continuously find highly irritating is the fact that the solution is staring us in the face. http://www.trampe.no/english/ "How come that Trondheim, the third largest city of Norway, has the highest share of cycling compared to all the other Norwegian cities? We believe there are there reasons:... One of the most important infrastructure elements is the bicycle lift Trampe. Since the opening in 1993, it's pushed more than 220 000 cyclist up the very steep hill BBrubakken in the historical heritage part of the city center" It seems to me highly unfair that if we expect people to commute with a bike then they must wear a hair shirt to do so BUT when people are engaging in 'sports' like Skiing,Snowboarding then it would be silly not to provide a means to pull them up the hill. Sorry for the rant I cycled in this morning. any links to the LSE report ? sheep On 11 Sep 2007, at 10:29, Alain Chiaradia wrote: > The hill gradient is particularly prevalent in London, the flat > part of London, the South West corridor is not surprisingly the > area where they are most cycling trip to work... > > > > See LSE report on London density - there is nice map that clearly > show it - it needs cross referencing with London topography. > > > > This does not answer all the questions? > > > > ________________________________________ > > > > Alain > > ________________________________________ > > > > From: Alan Penn > Sent: 11 September 2007 09:44 > To: [log in to unmask] > Subject: Re: the use of number - 2 > > > > ... and hills - as someone who cycles up the Archway hill every > evening it would be very tempting to have an inexhaustible supply > of bikes at the top replenished by entropy restoring lorries... > perhaps they could even have a trailer on the back of the lorry for > knackered cyclists... > > > > Alan > > > > > > Reported in Local Transport Today > > > > Phil Goodwin is commenting. > > > > This is about cyclist and pedestrian.
