About the talk

Accessibility is a central theoretical and analytical concept in transportation, urban and social sciences.  A common accessibility measure is the space-time prism (STP): this is the envelope of all possible travel paths between two locations in geo-space and time given basic constraints on mobility. While STPs are powerful measures of potential benefits from accessibility, they neglect the costs of accessibility, especially environmental costs such as consumption of non-renewable resources and emissions of pollutants such as NOX and PM-2.5 and greenhouse gases such as CO2.  This presentation discusses research to extend the STP to include the environmental costs of accessibility and the development an application framework and GIS toolkit for applying prism benefit/cost measures in transportation planning and project evaluation.  In addition to its practical application, this research also advances theoretical understanding of STPs; in particular, analytical properties of the STP interior such as the distribution of visit probabilities and possible travel speeds.  

About the speaker

Harvey MillerHarvey J. Miller is the Bob and Mary Reusche Chair in Geographic Information Science and a professor of geography at The Ohio State University in Columbus, Ohio, USA.  His research and teaching focus on the intersection between geographic information science and transportation science.

He wants to understand how people use mobility and communications technologies to allocate scarce time among activities in geographic space—a perspective known as time geography.

He is also interested in the social dimensions of transportation, and the implications of human mobility and accessibility for sustainable transportation, livable communities and public health.

His main approach to questions of mobility, livability, and sustainability is the development and application of GIS and spatial analysis techniques to extract information from fine-grained mobility and spatio-temporal data.

He is also an urban enthusiast, recreation fanatic, and fellow traveler.  He loves to discover and explore cities.  He is a cycling nut who believes that bicycles can save the world.  He also likes wilderness travel and camping, skiing (both downhill and Nordic) and running.  He has frequent opportunities to travel internationally and lecture at conferences, workshops and universities. In more relaxed moments, he also loves books, films and quality television.
