Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of the effect of cycle lanes on traffic flows between Parliament Square and the City of London.

No assessment has been made. Cycle superhighways on the Transport for London Road Network are the responsibility of the Mayor of London. The design of parts of the East-West cycle superhighway which runs from the City to Parliament Square was modified following public consultation in order to reduce its impacts on other road users. Transport for London will be monitoring these impacts carefully, but as the cycle superhighway in question has been operational for less than a year it is too early to reach any definitive conclusions on this.
