Chippenham Multi-modal Transportation Model

Wiltshire Council


Chippenham, in Wiltshire, is identified as a town which is planned to accommodate major growth. To enable the assessment of the likely transport impact of major development proposals PFA Consulting, in partnership with SIAS, initially built a 'base year' micro-simulation traffic model of Chippenham. The model was later expanded into a multi-modal model for Wiltshire Council and was enhanced to enable the effects of 'peak-spreading' to be examined.

Significant new survey data was collected as part of the model building process and included roadside interviews, automatic number plate recognition, traffic counts and journey time surveys.

The Chippenham Transport Model allows the Council and developers to test future development options and highway schemes and is an important element of the evidence base for the emerging Local Plan.
