The results of this research demonstrate which types of infrastructure investment are most likely to support an increase in cycling
Transport policy across Europe in the past ten years has significantly shifted to
sustainable transport objectives and targets which are clearly linked to environmental and economic objectives. However, despite the policy support at national level, there is still a reluctance at local level to invest in high quality infrastructure for cyclists. In addition, many cyclist lobby groups ascertain that investment in dedicated infrastructure to encourage cycling is not required.
This paper sets out to explore these various views but ultimately, through consultation with over 2000 commuters, determines the factors which are most likely to influence cycle route choice. Of particular interest, the research sets out to definitively conclude on how investment in infrastructure (or otherwise) is most likely to be effective in achieving mode share targets for cycling.
A stated preference survey, undertaken by almost 2,000 cyclists and non-cyclists in the Greater Dublin Area was used to gauge preferences for a range of infrastructure types and route characteristics. Results from the survey were compared against individual characteristics, such as age and gender. In particular, the research aims to determine the correlation cycling confidence and infrastructure preferences.
The research results provide a robust data set which indicate the infrastructure types that are most likely to encourage an increase in cycling.
The research was undertaken in conjunction with Trinity College Dublin with the support of the National Transport Authority and Dublin City Council. The research was published in the Transportation Research Journal in 2013 and was also presented at the TRB conference in Washington DC.
