Editor's Notes

  • #4 Considering door-to-door trips and the time it takes to park a car or wait for a bus, cycling is indeed quite fast, especially over short distances up to 5 miles.
  • #5 There is a money value to time and in classic transport project appraisals, time savings deliver the bulk of benefits. And so it is important to remember that in urban centres, and especially at peak periods, bicycles are nearly as fast or faster than cars or public transport for short trips. For example; DOI 10,1016/j.trd.2010.07.002 Prudhomme et Bocarejo, 2005 cyclingindublin.com/why-cycle/ Because cycling is not affected by congestion, it’s surprisingly fast compared to taking the car. The department of transport says: “Data from the 2006 Census reveals that, for journeys within the Dublin Canal Ring, cyclists reached an average speed of 12km/h compared to just 15km/h for cars. For trips within the M50, the 2006 Census reveals an average speed for cyclists of 14km/h compared to 18km/h for cars.”

Because of this, over time, cyclists spend as much or more than motorists.

Face un choix compliqué que tout Maire connait – ou investir pour assurer la croissance de la ville – Beaucoup comme Maire Rahm à Chicago, ex-Maire Bloomberg à New York, Maire Li a San Francisico ou Maire Wharton à Memphis ont fait le choix de réhabiliter leur villes à coup de pistes et de bandes cyclables. Non seulement pour leurs habitants mais aussi pour les finances de leurs villes.

  • #28 So more cyclists are better … but recalling crash risks, more cyclists also increase crash numbers. Here I will talk about the safety in numbers hypothesis based on the observation that greater number of cyclists are associated with a drop in the crash rate. There are many plausible explanations for this observed phenomenon but limited evidence on causality. This is essential since a key question remains …. Does increasing cycling increase crashes?

  • #60 There is a temptation to install cycle tracks where it would be easy and cheap to do so. This temptation should be avoided. Cycle tracks should be built where they are necessary which is often where it is difficult and controversial. The cycling infrastructure should be direct, logical, comfortble and convenient otherwise existing cyclists may avoid them and potential new cyclists will notbike at all.
