My Traffic Simulation Toolchain Guide

My toolchain

After a year of iteration, my traffic-simulation toolchain has stabilized:

Why not VISSIM end-to-end

VISSIM's GUI is great for teaching and detailed scenarios, but its automation is weak. When I need to sweep parameters across thousands of runs, SUMO + TraCI's scriptability is essential.

A small tip

Setting TraCI's step length to 0.5s instead of the default 1s noticeably improves signal-switch fidelity, at ~30% more runtime. I debug at 1s, then re-run at 0.5s for the final result.

Tools extend the hand, but don't let them think for you.
