UXsim: Traffic simulation in Python

About

UXsim is an open-source macroscopic and mesoscopic network traffic flow simulator developed in Python. This webpage is a technical documentation of UXsim codes. Please visit Github repo first.

Example

Belows are simulation result where approximately 60000 vehicles pass through a 10km x 10km grid network in 2 hours. The computation time was about 30 seconds on a standard desktop PC. The first animation shows link congestion level and the second shows sampled vehicle trajectories.
