Improving the empirical basis for cycle planning

Abstract

The authors postulate that the lack of evidence of a growth in cycling in Government data sources, and reporting of contradictory trends in cycle use, reflect survey method deficiencies affecting major modes, and results in an under-estimation by planners and policy makers of the potential contribution that cycling can make to local transport. A method to estimate cycle usage on the UK National Cycle Network has been developed based on automated fixed-point continuous cycle count data supplied by local authorities. Data from this source is compared with Government measures of cycling. The adaptation of continuous count data to deliver an additional national-level indicator on cycle use is recommended. The need for development of an appropriate sample, additional analysis tools, and improved data checking techniques are noted, and opportunities afforded by improved cycle traffic monitoring are discussed.
