The decision to provide cycle lanes should be reached by reference to the hierarchy of provision (Local Transport Note 2/08 Table 1.2) and such tools as the CROW derived ‘speed/flow’ diagram (see below); they should not be seen as a universal solution. Where provided, they should be a minimum of 1.5m wide, continuous, made conspicuous across side roads at junctions and not abandon cyclists where roads become narrow, for example at right turning lanes. When cycle lanes are being introduced, the cost of remedial measures to the carriageway surface should be included within the scheme budget.
