This report describes two projects which apply studies of individual road user behaviour to construct predictive models for use in traffic design and planning. The first study concerns route choice behaviour in urban areas with applications in traffic assignment models, etc. A theoretical model is considered which describes the choice of route in terms of road users' preference for various route characteristics and of their estimates of the actual values of such characteristics. Using data from 691 home interviews, different hypotheses concerning the structure of such a model are tested, and some parameter estimates obtained. The second study was undertaken as part of a major investigation concerning the capacity of roads and intersections, with the focus on intersections without signal control. Theoretical models for the calculation of capacity and road user delay at such intersections are reviewed. The most important parameter in these models is the headway required in a major road flow for a waiting minor road vehicle to pass (critical headway). To study this parameter and its dependence on various influencing variables, a field study was undertaken comprising 18 intersections. In general, the results agree well with those of previous studies. /TRRL/
