Abstract Automated construction of location graphs is instrumental but challenging, particularly in logistics optimisation problems and agent-based movement simulations. Hence, we propose an algorithm for automated graphs, which vertices correspond to geographic locations interest edges direct travelling routes between them. Our approach involves two steps. In the first step, use a routing serv...

Almost since the beginning of its program operations, the Social Security Administration (SSA) has collected location and type of business data from employers-as a byproduct of the requirement that they report employee wages for benefit computation purposes. The agency has been able to draw on these statistical data for planning and policy analysis. Wage, location, and type of business data are...

Key scientific and application questions concern the relationships between individual-level activities and their effects on broader human phenomena, such as transportation systems and cities. Continuing advances in geographic information science, location-aware technologies, and geosimulation methods offer great potential for observational and simulation studies of human activities at high leve...
