Mobility surveys and transport modelling

Countywide multi-modal transport model travel patterns

In early 2015, AECOM developed a countywide multi-modal transport model (COMET).

They produced a Pattern of travel across Hertfordshire report which has helped us to understand how people travel in Hertfordshire. This has improved our understanding of how to develop the county's transport infrastructure and accessibility.

Hertfordshire county travel survey

The Hertfordshire county travel survey recorded how a large number of our residents travel.

 

District specific results

 

The results of these surveys have helped us to improve our existing transport structures and have assisted with developing new schemes.
