New article out: Health research needs more comprehensive accessibility measures

In our new article “Health research needs more comprehensive accessibility measures: integrating time and transport modes from open data” we discuss and demonstrate why and how both temporality and multimodality should be integrated in health related studies that include accessibility perspective. We provide evidence regarding the importance of using multimodal spatio-temporal accessibility measures when conducting research in urban contexts. In our case, we study the healthy food accessibility in Helsinki metropolitan area.

Our results show that both time and mode of transport have a prominent impact on the outcome of the analyses; thus, understanding the realities of accessibility in a city may be very different according to the setting of the analysis used. Neglecting time and (multiple) transport modes from spatial analyses may lead to overly simplified or even erroneous images of the realities of accessibility. Hence, there is a risk that health related planning and decisions based on simplistic accessibility measures might cause unwanted outcomes in terms of inequality among different groups of people.

Big funding from the Kone Foundation!

Our group got, in collaboration with conservation scientists Enrico Di Minin and Anna Hausmann, a considerable funding to study the potential of social media data in spatial planning, mobility research and conservation science. With this funding we can hire one PhD student and one post-doc for 3-4 years. We are grateful and happy!

MetropAccess-Travel Time Matrix is being updated!

The Accessibility Research Group is currently working on updating the MetropAccess-Travel Time Matrix dataset! The matrix consists of travel time and travel distance information across the Helsinki Metropolitan Region by walking, public transportion and car. The dataset will be updated to represent the current time tables and transportation network (for example including the Ring Rail Line).

The updated matrix will be distributed on the project website later this fall. In the meanwhile, have a look at the original Travel Time Matrix available in the Data-section.

Stay tuned!

New paper out: Accessibility of urban aquatic environments using PPGIS method

In our new joint article with Aalto University (Department of Real Estate, Planning and Geoinformatics) we examine access to aquatic environments from the environmental justice perspective. Participation GIS (PPGIS) method was used to provide multifaceted knowledge on the person-based accessibility patterns related to aquatic environments. Our accessibility tools were used to model the accessibility to water areas with different travel modes.

Article was published in Landscape and Urban Planning. Read the full article here:
