Bikesharing systems have gained popularity over the years and now face the challenge of being responsive and of meeting the growing demand. Thus, understanding the temporal pattern of bikesharing trips is paramount. This study examined data from Bikesampa (a fixed-station system operating in the Brazilian city of São Paulo) and applied k-means clus...

This paper investigates the activity behavior of residents of Paraisópolis, the second largest slum of São Paulo (Brazil). The study used data from a survey and one week of GPS traces of a sample of residents. Location data was the basis to infer individual stays and points of interest. Stays were clustered into 6 classes, based on spatial, tempora...

Studies conducted in cities from developed countries reveal associations between travel behavior and built environment. A priori we would expect that most of these associations hold for cities from developing countries but we do not have any basis to suppose whether or not they will be quantitatively the same because of differences in the nature of...

Telework has been adopted and studied in some countries for over 30 years; in Brazil, the phenomenon is in its early stages but rapidly advancing. This paper investigates how companies are shaping their telework policies: what the goals, benefits and limitations being experienced are. The results show that while the major barriers to telework adopt...

Urban Transportation Economics é um livro relativamente curto; sua concisão não sacrifica, porém, sua abrangência e consistência. O próprio autor o considera mais como uma revisão do estado da arte, embora contenha proposições originais. A ênfase do livro recai sobre o transporte individual.

A literatura técnica de planejamento de transportes se enriquece com o livro de Richardson, Ampt e Meyburg (1995) sobre Métodos de Pesquisa para Planejamento de Transportes. A necessidade de informações sobre os diversos aspectos da atividade de transportes, assim coma sobre os fatores que a condicionam e os impactos que provoca, é um dos requisito...

This chapter describes how public transit has a central role in the move towards sustainable transportation systems and the improved quality of life, particularly in large urban areas of developed and developing countries. Changes are required in public transit infrastructure, service and travel behavior to reach the goals of efficiently improving...

In the 1970s, Brazil was leading the implementation of high-flow bus priority schemes, but now cities are less capable of financing public infrastructures. This paper explores the private sector participation in the provision of transit infrastructure based on Public-Private Partnerships (PPP) for Bus Rapid Transit (BRT). The Porto Alegre BRT conte...

This chapter describes how the workshop started from a general recommendation of producing standards for travel surveys. Similar to what happened in some of the other workshops, the participants had to recognize the challenges presented by such a task, considering that travel surveys are generally specific with respect to objectives, resources, tim...

Mobility in the metropolitan region of São Paulo has declined in recent decades in spite of a general growth in motorization and living standards. Some important factors have been overlooked in the analysis of mobility. These relate to the evolution of sociodemographic attributes and to temporal changes in behavior: (a) changes in the population st...

A comparison is presented of the diffusion of the automobile in the metropolitan areas of Paris and Montreal and in two urban areas in developing countries-São Paulo, Brazil, and Puebla, Mexico. The comparison uses a demographic approach, based on the estimation of an age-cohort model. The model takes into account three combined aspects of time: th...

Conventional trip generation models are identified, as are the difficulties of model application typical of segmentation problems: identification and categorization of explanatory variables and of the interactions among them. The use of CHAID (Chi-Squared Automatic Interaction Detection), a criterion-based segmentation modeling tool, is explored to...
