SRA were originally founded initially to address social aspects of transport and this is still reflected in the interests of many of the current staff. The motivation then was the view that transport research, although proficient in technical matter, neglected social issues. While this situation has improved it is still the case that the links between health, employment, education and other policy areas are under-researched. SRA continue to investigate what  links transport to the world around it.

Another focus of research concerns understanding transport choices and ways of extending these choices so that people can use more sustainable transport methods. Examples of work in this area are studies of coach commuting, unlicensed driving, transport and employment reactions of motorists to bus travel, how people on low incomes can afford driving lessons and deterrents to walking and cycling.

SRA also work in many other areas of transport including transport planning, public transport, demand responsive transport, freight and logistics, car travel and road safety. See sub sections for more details.
