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. The most recent survey was in 2015.

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

District specific results

National Highways and Transport (NHT) Survey

The NHT Public Satisfaction Survey collects public views on Highway and Transport Services such as roads, footpaths and public transport. This annual survey is a collaboration between Highway Authorities across the UK.

The results of this survey can influence the amount of investment the Government allocates to Hertfordshire County Council for highways improvements and maintenance, so we urge residents to complete this if requested.

See the survey results for 2016 and find out more on the NHT homepage.
