Cromwell Trucks and Online Marketing Surgery have created their Road Delay Report, which helped rank roads in West Sussex based on their delays.
This determines where people are waiting the most on their travels.
The recent data around road delays in England was taken from GOV.UK, where it was motorways and major A roads, and local A roads.
It looks at how many seconds a vehicle is held up per mile travelled on average in 2023.
