§ Mr. Kenneth Carlisle
Motorway performance depends on a wide range of factors, including particularly the traffic volumes at the time, maintenance requirements and accidents. Investment is carefully targeted to produce maximum return in reducing delay and accidents, subject to full environmental appraisal. The economic assessment of English motorway schemes continues to produce an overall benefit-to-cost ratio of 2.6:1.
The growing pressures of managing the network of motorways and other trunk roads in England were recognised in the reorganisation of responsibility within my Department in 1990 when regional network management divisions were established.
