ABSTRACT
A characteristic of many transport studies of the 1960s and early 1970s was that demand was treated only in aggregate terms, with little understanding of journey purpose or type of traveller. This chapter begins with examining trip length distribution, and from this, the importance of different modes, and effects of city size. Differences in travel behaviour according to person type and household structure are then examined, together with change over time in such patterns. Shifting from the demand to supply side, the chapter then focuses on finance and system management. For purposes of comparison with earlier studies in specific cities, and with studies outside Britain, it is desirable to analyse motorised travel only, since the non-motorised modes are often omitted altogether, or treated in an inconsistent fashion. By use of detailed household interviews, it is possible to illustrate typical activity/travel patterns during the working/school day for such households, and how decisions of the members' interact.
