asked the Minister of Transport what progress has been made with the implementation of recommendation 5 of the Standing Advisory Committee on Trunk Road Assessment; and if it is his intention to publish such, before and after studies have been, or will be completed.

The procedures and analytical tools are being developed for a programme of regular before and after traffic studies which I hope can be put in hand later this year. The Standing Advisory Committee on Trunk Road Assessment is being kept in touch with its development. In the meantime, certain specific individual studies have been put in hand to examine changes in environmental conditions as well as traffic be- haviour. The results will be published in appropriate forms.
