Issue 4: Network-wide speed-flow curves

Abstract

The net­work as a whole behaves in the same way that a sin­gle link does, with a mea­sur­able capac­ity, and exhibits a speed-flow rela­tion­ship, based on empir­i­cal obser­va­tions of net­work speeds and net­work flows, which fol­lows the tra­di­tion­ally hockey-stick curve that rep­re­sents the behav­iour on indi­vid­ual links.

Issue 3: Cycle Flows and Weather: an algo­rithm for adjust­ing for ambi­ent tem­per­a­ture and rain­fall in cycle counts.

Abstract

This paper reports a suc­cess­ful esti­ma­tion of the coeff­fi­cients to adjust observed cycle counts for changes in ambi­ent tem­per­a­ture, rain­fall, week­ends, and bank holidays.

On Greater London’s main roads, which carry a sig­nif­i­cant pro­por­tion of London’s cycling, cycle flows rise on aver­age by 1.8% for each degree Cel­sius increase in mean tem­per­a­ture on work­ing days, and by 2.7% for each degree Cel­sius at week­ends and bank holidays.

The pres­ence of rain­fall typ­i­cally reduces flows by 9.1% on a work­ing day, and by 13.9% on other days. This reflects a higher pro­por­tion of dis­cre­tionary (“fair weather”) leisure travel at week­ends, in con­trast with util­ity (typ­i­cally com­muter) cycling dur­ing the week.

Issue 2: the Mode Shift Ben­e­fit Matrix: Money for Walking

This paper was pre­sented at the 2005 Money for Walk­ing con­fer­ence, organ­ised by Liv­ing Streets and the Cor­po­ra­tion for London.

This paper presents the mode-shift ben­e­fit matrix: a solu­tion to the prob­lem of how, cost-effectively, to cal­cu­late the eco­nomic value of the costs and ben­e­fits of a scheme that is designed to cause a modal shift.

Abstract

In this paper, I exam­ine the evi­dence for the propo­si­tion that places with high cycling tend to have a higher pro­por­tion of female cyclists. Pos­i­tive cor­re­la­tions sup­port­ing this are found within two sep­a­rate data sets: the 2001 Cen­sus, and the Lon­don Area Travel Sur­vey 2001. Com­par­isons are made to results from the Dutch annual national travel sur­vey, which shows high cycling fig­ures nation­ally and by indi­vid­ual province, sus­tained high modal share across all ages, includ­ing the over-75s, and a con­sis­tent bal­ance between the num­bers of male and female cyclists. Recent increases in the amount of cycling in Greater Lon­don (40% growth on the main road net­work, the TLRN, between 2001 and 2004), have been accom­pa­nied by an increase in the pro­por­tion of women within the cycling pop­u­la­tion, from 27% in 2001 to 40% in 2005
