NEW PRIMARY ROADS AND SUB-REGIONAL ECONOMIC GROWTH: FURTHER RESULTS--A COMMENT ON J.S. DODGSON'S PAPER

A case study of a proposed new road (circumferential to London and of about 50 miles length) involved estimation of the significance of commercial vehicle trip cost savings to local industries due to the provision of the road. This was measured in relation to the total of such costs and employment. The results support Dodgson's empirical conclusions that secondary benefits from new roads by way of accelerated employment growth are negligible overall. An implication of this is that direct estimates of traffic benefits cover all such benefits necessary to the overall evaluation of new road proposals. Commercial vehicle trips were modelled using methods which related such vehicle flows to predicted passenger car flows. A rough check was made, utilizing screen line counts, to ensure that the proportion of commercial vehicle trips in total traffic area was not inconsistent with the national figures used in the modelling process. Net benefits to industry were estimated, and the employment structures of towns adjacent to the proposed new route were examined. The new route is expected to stimulate the economies of 2 towns which had a high incidence of employment in transport intensive industries.
