I think pedestrianisation is good in many places but feel that the approach of widespread 20mph zones is more applicable in existing cities. Public transport will always struggle in most cities to give the flexibility that a car of sorts can give particularly on non radial routes. UK cities need to invest far more in public transport and I like your reconceptualising of it as support for transactions. The rapid urbanisation and suburbanisation based on the car in many countries is seemingly worryingly short sighted given the carbon challenges we all face. In Algiers for example the ‘old city’ is very densely populated, many transactions are undertaken by foot but the outward spread of the city into new low rise suburbs and the large road building programmes seem short sighted. They however have opened after decades of building work a new metro line with seemingly a commitment to its expansion so the picture is mixed
