The final gridlock

TL;DR: A collection of nine papers on the possibility of gridlock - parts of a city being completely seized up due to traffic congestion - and possible approaches to easing the problem is summarised in this article.

Abstract: The author summarises a collection of nine papers on the possibility of gridlock - parts of a city being completely seized up due to traffic congestion - and possible approaches to easing the problem. Two papers cover the strategic policy background and the need for a radical rethinking of current approaches. It is suggested that America has advanced through the process of suburbanisation, population structure changes and the mismatch of jobs and housing. The need for action is now reinforced by environmental and health concern. Approaches available are reviewed in the other papers; these include road pricing, controls through taxation on ownership or usage and improved public transport facilities. There is evidence that a co-ordinating policy of demand management and investment in high quality public transport can tempt people from their cars. Information systems can also help to reduce congestion but it may only delay the gridlock. Cities cannot accommodate an unrestricted demand from car drivers but it seems that people are very reluctant to give up their cars no matter how bad congestion is. Government appears reluctant to support draconian measures to combat congestion. (TRRL)
