Samenvatting
Encouraging the re-emergence of public transportation in cities requires a total assessment of the physical and behavioral characteristics of the user population as well as their economic, social and esthetic preferences. Research in all of these area is needed to meet the urban transportation challenge of this decade and for many to come. A good start has been made in some general areas. The greatest need for information seems to be in understanding the individual user and in determining what he needs and prefers.
