Improving Cities

Helsinki: Declining Deaths on the roads, due to good policies

Cities around the world are beginning to implement policies that are creating a modal shift away from cars and towards walking, cycling and public transport. Multiple benefits can flow from such policies. Death and injury from traffic accidents can be reduced, or eliminated entirely. Air quality can be improved leading to declines in respiratory illness. Carbon emissions can be reduced. People can enjoy spending time on the streets, so strengthening social cohesion and acting to reduce crime. There are also tangible economic benefits as people eat, drink and shop on the city streets. Time can also be saved as traffic volumes decrease and as services are re-localized. Maybe most important of all, people enjoy hearing bird song, human conversation and children playing, rather than the continuous roar of traffic: there are improvements to mental health.

Many cities exemplify this process. The above graph shows road traffic deaths in Helsinki, which have declined dramatically over recent decades. The Belgian city of Ghent has achieved dramatic results by splitting the city into zones and limiting car connectivity between them while increasing access for public transport, walking and cycling. Birmingham is planning to copy some of the lessons from Ghent. Anne Hidalgo, the mayor of Paris, is planning to reduce, by 60,000, on-street car parking spaces, and to re-localize services in order to create the 15 minute city. In many cities (notably Berlin) electric cargo bikes are beginning to replace diesel delivery vans. It’s good to see the Co-Op are trialling this at one of their London stores. One innovation that is proving popular in France and Holland is the pedal powered school bus. Even here in Hereford we have Pedicabs and the Beryl bike share scheme.

Many of these changes can be implemented cheaply and quickly. Much more cheaply, more quickly, and with many more benefits than can ever accrue from road building. As governments and local councils lead on these kinds of changes they can also help in the roll-out of hydrogen fuel cell and battery electric vehicles. With the right mix of new policy and new technology cities may yet become safer, cleaner, less polluted and happier places to live. It is good to see many politicians at last beginning to understand this and to act to bring about these changes.
