[GeoSparkSim](http://www.public.asu.edu/~jiayu2/geospark/publication/geosparksim-mdm-2019.pdf) is a scalable microscopic traffic simulator, which extends Apache Spark to generate large-scale road network traffic data and help data scientists to simulate, analyze and visualize large-scale traffic data. GeoSparkSim converts road networks into Spark graphs, simulates vehicles to Vehicle Resilient Distributed Datasets (VehicleRDDs) and provides a simulation-aware vehicle partitioning method to parallelize simulation steps, balance workload and handle the dynamic spatial distribution.

It is mainly developed by the contributors from [Data Systems Lab](https://www.datasyslab.net/)

### Note
GeoSparkSim team is developing new feature under dev. Please use the version in stable branch to generate your data.
