40 Conclusions Street types can be applied to the real world. People temper their expectations. Streets underperform compared to expectations. The most challenging streets are those with high movement and high place functions i.e. City Hub and City Street. Both movement and place functions affect healthy street scores. External and personal factors also affected scores. The healthy street indicators are inter-related: supports a whole-street approach. Survey now being used to see if it can measure changes in perceptions to evaluate impacts of new schemes...

41 20 mph and Healthy Streets Our survey results show that streets with less vehicle dominance score better across indicators. We don t know if reducing the speed limit to 20mph would improve scores. We have conducted baseline surveys in 2 locations on both Brixton High Street and Clapham High Street. Both of these streets are piloting 20 mph and we would like to see whether perceptions change when the speed limit is reduced.

42 20 mph and Healthy Streets

43 Objective measures of Healthy Streets We have developed a set of technical criteria for scoring against the Healthy Streets indicators. We have piloted this on a sample of schemes and found that the technical scores are generally below the experience and the expectations of the public.
