Welcome to Enhanced Transportation Flow Open-source Microscopic Model (ETFOMM) project. 

ETFOMM inherits 40 years of FHWA development of traffic simulation algorithms and flow theories while overcoming CORSIM’s limitations in supporting research. For more detail functions about ETFOMM, please refer to https://www.fhwa.dot.gov/publications/research/operations/17028/17028.pdf. For tutoring, technical support and future updates, please visit ETFOMM.org or email etfomm@ngsim.com.

This project also includes ETFOMM Application Programming Interface (ETAPI) that provides communications between ETFOMM core simulation engine and user-developed applications (Apps) through ETRunner, a Windows console program.
