... 3 2 Emerging Practices and Activity-Based Models 2.1 Introduction to Diurnal Population Movement and Spatiotemporal Data In this section we examine the current and emerging methods and practices for using spatiotemporal population data sets and their applicability to aircraft noise modeling. Spatiotemporal data considers both the spatial and temporal aspects of population counts, measuring the number of people present at a given location during a specific time period.
From page 4...
... 4 population data approaches the granularity available from census data. In the United States, census blocks represent the smallest spatial unit available, and may be as small as a few houses or a city block.
From page 5...
... 5 The ARC has developed a visualization tool (http://atlregional.github.io/ABMVIZ/ ) to show the movement of the population throughout the region through time.
From page 6...
... 6 by differentiating two activities ("home" and "work") and by operationalizing the temporal dimension of human activities using a very detailed movement profile data set.
From page 7...
... 7 that the net daytime populations of the study areas decreased significantly when compared to the residential population but did not account for non-residents such as tourists. • Freire (2007)

... 9 was calculated as an hourly average concentration on the road network for the whole study area. The average transport concentration was estimated by selecting the hourly concentrations from the grid points closest to each road segment and averaging those to a concentration value for the whole study area.

... 10 2.4 Spatiotemporal Data for Use in Marketing Spatiotemporal data can be used to better understand a target market for a product or service, or when and where to reach a target customer. One common way to build such data is with mobile phone location data.
From page 11...
... 11 2.5 Spatiotemporal Data and Aircraft Noise Studies Noise impact modeling is typically undertaken with a variety of scientific models that assess the exposure of people on the ground to sources of noise such as vehicles, trains, aircraft, etc. Noise impact modeling typically uses static population distributions obtained from the U.S.
From page 12...
... 12 dasymetric model that utilizes census data. Typically, a localized, activity-based model will require localized knowledge and potentially be dependent on the inclusion of a manual survey of a subset of the population.
