Abstract

Data generators have been heavily used in creating massive trajectory datasets to address common challenges of real-world datasets including privacy, cost of data collection, and data quality. However, such generators often overlook social and physiological characteristics of individuals, and their results are often limited to simple movement patterns. To address these deficiencies, we propose an agent-based simulation framework that facilitates the development of socially plausible models of human behavior, in which agents correspond to individuals that act contingent on personal preferences, goals, and needs while at the same time within a realistic geographical environment. Researchers can use a drag-and-drop interface to design and control their own world including the geospatial and social (i.e. geo-social) properties. The framework is capable of generating and streaming very large data that captures the basic patterns of life in an urban area. Streaming data from the simulation can be accessed in real time through a dedicated API.

Main features

• Drag-and-drag style model builder
• Simulation based on human behavior model
• Streaming (ZeroMQ PUB/SUB patterns)

Patterns of Life

We can observe patterns of life. The following figures shows mobility and hunger level of agents over time.
