The article discusses how people travel long distances in the UK differently from shorter trips. The researchers studied data on how people choose their mode of transport, like trains or planes, for long journeys. They found that long-distance travel makes up a big part of total trips and emissions. The study shows that factors like income and time influence how people choose their travel mode. The researchers used real travel data to create models for different types of long journeys, like commuting or business trips. They also looked at how changes in transport options, like low-cost airlines, affect long-distance travel. The findings help in predicting how new transport policies, like high-speed rail, will impact long-distance travel in the UK.
