The purpose of this paper is to describe the development of the Canadian Active Living Environments (Can-ALE) dataset: a Canada-wide set of four individual and four summary measures that characterize the favourability of active living environments in Canadian communities at the dissemination-area level. This study reports on analyses which guided the selection of measures and derivation data sources for the dataset. The objective was to produce a national database entirely from open data and to evaluate the performance of open data compared with traditional or proprietary sources., Health Reports, Volume 30, Issue 5 May 2019 Pages 16–25

Cet article a pour objet de décrire la création de l'ensemble de données sur l'accessibilité à la vie active dans les milieux de vie au Canada (AVA-Can) : un ensemble pancanadien de quatre mesures individuelles et quatre mesures agrégées qui caractérisent l'accessibilité à la vie active dans les collectivités canadiennes au niveau des aires de diffusion. Cette étude fait état des analyses qui ont guidé le choix des mesures et des sources de données pour constituer l'ensemble de données. L'objectif était de produire une base de données nationale seulement à partir de données ouvertes et d'évaluer le rendement des données ouvertes par rapport aux sources conventionnelles ou privées., Rapports sur la santé, Volume 30, Issue 5 mai 2019 Pages 17 à 27

The set of models available to predict land use change in urban regions has become increasingly complex in recent years. Despite their complexity, the predictive power of these models remains relatively weak. This paper presents an example of an alternative modeling framework based on the concept of a Markov chain. The model assumes that land use at any given time, which is viewed as a discrete state, can be considered a function of only its previous state. The probability of transition between each pair of states is recorded as an element of a transition probability matrix. Assuming that this matrix is stationary over time, it can be used to predict future land use distributions from current data. To illustrate this process, a Markov chain model is estimated for the Minneapolis-St. Paul, MN, USA (Twin Cities) metropolitan region. Using a unique set of historical land use data covering several years between 1958 and 2005, the model is tested using historical data to predict recent conditions, and is then used to forecast the future distribution of land use decades into the future. We also use the cell-level data set to estimate the fraction of regional land use devoted to transportation facilities, including major highways, airports, and railways. The paper concludes with some comments on the strengths and weaknesses of Markov chains as a land use modeling framework, and suggests some possible extensions of the model., Tema.

Transportation systems are built with the intention to serve communities by providing accessibility and mobility. Yet seniors residing in these communities face different challenges compared to regular commuters. Seniors have special needs in terms of desired destinations and challenges faced due to limitations in mobility and decline of accessibility levels where they reside. In this research paper we discuss major findings from a mail-out mail-in survey conducted in Hennepin County, Minnesota to measuring met and unmet urban transportation needs of seniors. Compared to previous research this study uses primary collected data rather than relying on travel surveys, which does not measure the unmet urban transportation needs of seniors. The findings from this survey is consistent in term of measuring the existing travel behavior of seniors, which raises our confidence in the information being collected related to the unmet transportation needs of seniors. Seniors are found to be generally independent and rely mainly on auto usage to reach desired destinations at higher rates compared to the rest of the population. The majority of seniors reported although they are currently independent they do know that such independency is not permanent and they have to learn more about alternatives available to them. This study helps transportation engineers and planners in better understanding the current and future challenges that they will face with an aging population. Os sistemas de transporte são construídos com a intenção de servir as comunidades, proporcionando acessibilidade e mobilidade. No entanto, os idosos que residem nessas comunidades enfrentam desafios diferentes em comparação com os passageiros regulares. Idosos têm necessidades especiais em termos de destinos desejados e desafios enfrentados devido a limitações em mobilidade e diminuição dos níveis de acessibilidade, onde eles residem. Na presente pesquisa discutimos as conclusões principais de uma pesquisa com questionários enviados por correio realizada em Hennepin County, Minnesota, para medir as necessidades atendidas e não atendidas de transporte urbano de idosos. Em comparação com a pesquisa anterior, este estudo utiliza dados primários coletados em vez de confiar em pesquisas com viajantes, que não medem as necessidades não atendidas de transporte urbano de idosos. Os resultados deste estudo é consistente em termos de medir o comportamento de viagem existente de idosos, o que aumenta nossa confiança na informação a ser recolhida relacionada com as necessidades não atendidas de transporte de idosos. Revelou-se que os idosos são independentes e se baseiam principalmente na utilização de automóvel para alcançar destinos desejados, em uma proporção mais elevada em comparação com o resto da população. A maioria dos idosos relatou que, embora sejam atualmente independentes, eles sabem que tal independência não é permanente e eles têm de aprender mais sobre as alternativas disponíveis a eles. Este estudo ajuda os engenheiros e planejadores de transporte para uma melhor compreensão dos desafios atuais e futuros que terão de enfrentar com uma população envelhecida.
