Personalised Travel Planning (PTP) can have a significant impact on travel behaviour and travel patterns, helping to achieve more sustainable travel practices and healthier lifestyles, which in turn contribute to a more socially inclusive community and help protect the environment. PTP can be effective both amongst existing residents and communities and in new developments.
In Cardiff the project, funded by Welsh Government, and supported by Local Authorities, targeted 63,000 households in Cardiff and Penarth in a 15 month period. Stage 1 commenced in north Cardiff in September 2011. Stage 2 was undertaken in Spring 2012 and covered the western and southern parts of the city, as well as Penarth, whilst the final stage, Stage 3, covered the east of the city, during Autumn 2012.
After control group effects had been taken into account, the after survey showed a 12% relative reduction in car-as-driver trips across the PTP target population, with a reduction from 45% of trips being car-as-driver trips observed before PTP, to 40% afterwards.
Sustrans has also undertaken PTP in the locations summarised in Table 1:

The results demonstrate that the PTP can achieve a mode shift away from car driver of 10% or more.
