Is cycling infrastructure in London safe and equitable? Evidence from the cycling infrastructure database

We describe and analyse a new, open dataset of surveyed cycling infrastructure in London UK. demonstrate its potential to contribute research evidence-based policy development through spatial analysis provision London, before evaluating administrative boroughs on their mix compliance with UK Cycle Infrastructure Design Standards. processed cleaned the 233,596 records Cycling Database (CID) that contains nine types. To support comparison between boroughs, was normalised borough area, population size level commuter cycling. generated variables capturing cyclist separation from motor vehicles estimated cycle lane for such segregation against design standards. Each CID record survey date, location, infrastructure-specific accompanying photographs. Traffic calming assets are numerous distributed throughout London. Cyclist signals, crossings, Advanced Stop Lanes lanes tracks less more commonly seen inner rather than outer Normalisation by area did not change these patterns. Six percent on-road length is physically segregated vehicles. Estimated standards notably higher 66% exceeding mean compared just 24% boroughs. In this first systematic description we have demonstrated quantitively qualitatively compare method estimate found equally across may be quality provides safe space Such datasets critical evaluate guide health transport policies. • New, shows inequalities London’s infrastructure.
