The report describes hypothetical Cabtrack networks laid out in Central London and Birmingham. Estimates are made, on the basis of traffic survey statistics, of the likely travel demand in 1981 in the areas covered by these networks. In Central London the proportion of this travel demand assigned to the networks is based on percentage modal splits estimated for each type of trip. In Birmingham comparisons are made, for every trip recorded, of the relative attractiveness of travel by Cabtrack and by other modes of transport, and passengers are assumed to use Cabtrack if it is more attractive. On these assumptions loadings of all the cabstops and links of the networks are calculated. The costs of travel on the Cabtrack systems are then estimated. These seem reasonable, despite pessimistic assumptions as regards the operation of Cabtrack, and a probably over-optimistic view of the attractiveness of road transport in 1981.
