Summary
Transport Modelling is very important in order to: • Understand current conditions • Identify improvements • Assess improvement options • Present options to key decision makers
/ stakeholders • Improve transport provision
Three Key Modelling tools have been presented, although many others exist: • Wide area modelling • Local area modelling • GIS / accessibility
Modelling tools have not caught up with changing technology. Many opportunities to influence and change
current approaches and techniques
