Conceptual aspects of mode choice determinants regarding nonmotorized transport in developing countries are described. The influenceof city size, trip length, and income is discussed with particular reference to the poor. Nonmotorized modes will be important for a long time, and planners need to devise methods that recognize the majority of trips made using these modes. Mode choice and various factors influencing it in katmandu are presented to illustrate the importance of nonmotorized modes, particularly walking. Traffic studies in three different areas indicate that exclusive poedestrian and bicycle precincts in old areas of central business districts with narrow streets can be quite successful. This success could be replicated in other asian cities. Examples of inefficient use of street space are given to indicate a lack of application of normal traffic engineering techniques and enforcement of traffic discipline. Experience in katmandu indicates that exclusive nonmotorized mode precincts provide large volumes of person-trips, particularly by walking. These precincts must be related to street geometrics and adequate bypass routes must be provided. This paper appears in transportation research record no. 1294, Nonmotorized transportation 1991 .
