Abstract:

The ETFOMM (Enhanced Transportation Flow Open Source Microscopic Model) Cloud Service (ECS) is a software product sponsored by the U.S. Department of Transportation in conjunction with the “Microscopic Traffic Simulation Models and Software—An Open Source Approach” project. ETFOMM’s primary components are the core microscopic traffic Simulation Engine (ESE), a graphical user input editor (ETEditor), a 3D traffic visualization tool (ETAnimator), and a database in cloud service environment. Moreover, the SSAM is being converted into open source software, enhanced, and integrated as part of ESE. SSAM is a popular safety tool box that utilizes the microscopic traffic simulation vehicle trajectories to generate safety performance measures such as: Minimum time to collision (TTC). Minimum post-encroachment time (PET). Initial deceleration rate (DR). Maximum speed (MaxS). Maximum relative speed difference (DeltaS). Location of the conflict event (CLSP, CLEP). Maximum “post collision” DeltaV (MaxDeltaV).
