ABSTRACT
The rhythmic structure of time use and travel is a fundamental element of daily life. Any analysis of the character and determinants of rhythmic patterns in individual travel behaviour requires a conceptual background and an appropriate methodological approach. Hazard modelling refers to the terms event, duration and probability or risk. Hazard modelling deals with the analysis of timing and duration and is used extensively in fields of technical and social sciences such as biometry, mechanical engineering and market research. Analysts usually apply linear regression models as a standard approach to analysing the relationship between a response or dependent variable and a set of independent or predictor variables. Hazard modelling not only considers durations as essential determinants for the probability of an event's occurrence, it is also able to incorporate duration-independent determinants such as socio-economic attributes or traveller's commitments. Han and Hausman proposed an ordered-response model. Conceptually, it belongs to the group of discrete-choice models as durations are treated as categorical.
