A computer assessment has been made of 'no entry' restrictions applied to goods vehicles over four gross weight limits in three different control areas in Swindon. Changes in goods vehicle movements, their environmental effects and their costs have been predicted. The results have been compared with those for 'no entry except for access' controls obtained previously. It was found that 'no entry' controls would be far less cost-effective than 'no entry except for access' controls, typically costing two or three times as much to obtain the same environmental gain. It was also found that the cost-effectiveness of 'no entry' controls would not be improved by the provision of a simple type of transshipment centre on the town periphery.
