Chapter 3 – Part four: A central metropolitan block

Accumulation of traffic from a series of areas

310

If a primary grid on the lines discussed above were to be established in the centre of London, the volume of traffic passing along any section of the grid would be the cumulative flow generated from all the areas enclosed and passing along that section. We have not attempted to investigate fully the volume of traffic that would build up on all sections of the network grid, but we have satisfied ourselves that such a system would be feasible over a limited area such as the 25 square miles of Central London, provided that longer distance through traffic were accommodated on regional distributor roads. The sections of primary distributor bordering our study area would require at least four lanes in each direction.
