Cyclists now outnumber cars on five central London Thames bridges

New data shows that bicycles now outnumber cars and taxis northbound on five London bridges in the morning rush hour during 2010.

The increase in bicycle traffic strengthens the case for the reallocation of road space and an enforced 20mph speed limit on London bridges and their approaches.

Cutting speeds saves lives and is a highly cost-effective road-danger reduction measure.

A little-publicised 2008 Transport for London study (which LCC played a key role in publicising) concluded that enforced 20mph speed limits on just four bridges – Putney, Vauxhall, London and Westminster (where collision rates were highest) – would save the capital £7m pounds over five years.

The study compared the cost of installing speed cameras against the financial cost of road collisions as estimated by the Department for Transport.

A report for the DfT in 2000 showed that "broadly each 1mph reduction in average spend is expected to cut accident frequency by 5%".

The new data on bridges shows that since 2000 rush-hour cycling levels have gone up by approximately 140%, while private car flows have fallen by about 40%.

Cyclists now account for a quarter of all bridge traffic in the morning peak.

Blackfriars Bridge, where LCC groups campaigned successfully for improved provision for cyclists, shows among the highest increases in cycle flows.

If you live or work in the City of London, this week is your last chance to respond to the City of London Local Implementation Plan.

The Cyclists in the City blog provides key contacts and some suggestions for changes that need to be made, including a 20mph limit throughout the Square Mile.

It might be very illuminating to subject TfL's ststistics to a Benford's Law analysis. One never knows what sort of things might be revealed.
