The analysis of journey structure: linkage between different stages of a journey

Journeys are usually made in a number of stages involving a series of consecutive stages or trips which are linked in the sense that each stage or trip follows and precedes another stage or trip, but the decision to enter or leave a particular stage or trip may or may not be dependent upon some function of the last one entered. This report sets up tests to determine whether such 'dependent' linkages exist. One possible approach is that of markov chains, and the use of this technique in this and other circumstances is investigated. A particular data set based on the 1971 reading survey has been employed to demonstrate the working of the tests, and it is shown that in this town markov chain linkage between different stages of a journey cannot be demonstrated. The absence of such checks in other published papers using markov approaches throws some doubt on their utility. Data on the movements of pedestrians in the basingstoke shopping precinct have been used to show how such tests can be used in practice, and a stationary first order chain is demonstrated to be consistent with these data.
