Description:
Spatial accessibility refers to the measurement of to what extent people can use the services of interest. Recently, many scholars have focused on analyzing the dynamic relationships between supply and demand across space and time through the Two-Step Floating Catchment Area (2SFCA) family of methods and novel new methods like the Rational Agent Access Model (RAAM). These methods have been widely applied to economics, geography, public health, social science, and etc.
However, due to a lack of datasets of observations (i.e., demands, supplies, and traffic), there is an inevitable uncertainty in the measurement of spatial accessibility. In addition, dynamic changes in urban environments spur the need to advance accessibility measurements by integrating time-dependent phenomena and considering employing various transportation modalities to the infrastructure of interest. Through this session, we aim to seek challenges that the current methodology faces and potential outcomes with outstanding scholars across various domains, including but not limited to Geography, Geographic Information Science and Systems, and Urban Planning.
We are particularly interested in presentations that will discuss issues relating to:
* Advancing the methods of 2SFCA family and proposing novel new methodologies
* Measuring inequity of urban (or rural) infrastructure
* Uncertainty in spatial accessibility measures
* Reproducibility and replicability of spatial accessibility
* Data- and computation- intensive spatial accessibility measures
