Although a high proportion of trips in developing countries are invariably made on foot or by bicycle, insufficient importance has been placed on them in the past. This article describes the methods adopted in a study of Nairobi in which such trips were fully considered, being included in all stages of the modelling procedure in which a novel modal split model was developed to deal with three modes. In the survey, 4000 households were interviewed and a comprehensive traffic survey was undertaken. Particular attention was given to ensuring that the data for walk, cycle and public transport trips were adequate. Some results of this survey are presented and discussed. An outline of the modelling procedures adopted together with an indication of the results is given. The calibration of the transport model is described in detail. Two alternative public transport systems were examined in long-term tests, one entailing the use of rail rapid transit where demand was sufficient, the other embodying the use of exclusive busways. The transportation network for 1985 is shown and the recommendations for the 1985 transportation plan are given. /TRRL/
