On a different, but linked, topic a little bit of flesh has been put on the school travel proposals mentioned in Wednesday's Queen's Speech.
The government says that around twenty Councils will be allowed to carry out pilot projects to find innovative ways to improve school travel. The Draft School Travel Bill will also allow Councils to charge for some school bus services which are currently provided for free as long as they spend the money on improving school travel.
However, the CTC argues that the government must work to increase the availability of cycle training if its proposals to charge for school buses are not to increase car use and congestion on the school run.
Roger Geffen, CTC campaigns and policy manager, said: In order to position cycling as a viable option for parents and children, CTC will argue that government should ensure that cycle training is available for all primary and secondary school children, and we will look for opportunities to include this in the Bill when it is published.
CTC believes that quality cycle training schemes for pupils of all ages should be integral to the pilot programme, and that Councils should be required to make cycle training to recognised standards available for all pupils in their areas.
The Queens speech also included details of a Traffic Management Bill which is intended to give Councils and the Highway Agency more powers to keep traffic moving, particularly by controlling road-works. Since cyclists are the group most greatly affected by poor quality roads, the CTC said it will seek to ensure that pressure to complete road works quickly does not result in a lowering of standards.
The CTC was disappointed that the anticipated Road Safety bill failed to materialise, and regards this as a missed opportunity for tighter legislation on speeding and other forms of dangerous driver behaviour.
