§ Mr. BerminghamTo ask the Secretary of State for Transport what proportion of development work on mathematical transport models for use in analytical work was tendered out to consultancies in each year since 1983; and if he will make a statement.
§ Mr. Peter BottomleyThe Department's records do not enable a year-by-year breakdown to be compiled. The development of models often takes place in step with their operational use, as needs for improvement arise.
The best estimate which can be made is that for the period 1983 to date. 76 per cent. of development has been carried out by extra mural contract and 24 per cent. in-house mainly at the transport and road research laboratory.
