                                            D 

“Bike  sharing”  have  become  popular  words  in  cities  from  Cape  Town  to  Shanghai  to  Melbourne.  Planners, polit icians and  media keep showing off their benefits: reducing pollut ion, traffic jams,  travel costs and oil dependence, while  improving  public  health.  Bike  sharing  also  helps  make  cities  appear  modern,  dynamic  and world-wide-----qualities much sought after by the creative class.  

But  what  makes for a successful public bike-sharing program?  This is an important question because fixing one requires significant public and private investment and adjustment to the built environment.  While  many programs have been launched among  much praise, often their popularity has soon declined.  Many end up operating at a financial loss and  depend  on  other  profitable  businesses to cross-subsidize  (交叉补贴) them.  Some  have  resulted in thrown-away bikes becoming an eyesore. 

Understanding which factors encourage or stop public bike sharing is critical in helping cit ies decide whether such a program is workable, before considering what design and sitting  will  work best. 

Drawing on current knowledge,  we discuss the importance of the local landscape, climate, cycling infrastructure (基础设施) and land use.  We also touch on other factors, such as the legal environment and the characteristics of the bike-sharing program itself. 

Take natural environment for example. Two natural environment factors are known to affect participation: hilliness and  weather.  Hilliness discourages balanced bike-sharing use, as users avoid returning bicycles to stations on hilltops. 

Those stations end up being empty, while stations on flat areas are often full, so users cannot find a station to return their bikes. 

As  for  weather, ideal temperature  ranges  vary  by the  climate  zone.  Case  studies  show  warm  and  dry  weather encourages  public  bike-sharing  use.  Rain  and  strong  wind reduce the  frequency  of trips.  However, some  approaches, such as providing sheltered, shaded, or even heated or cooled cycling infrastructure, could prove useful.
