Part XVII: SUMO Microsimulation
Microscopic traffic simulation — SUMO architecture, car-following models, the OSMnx-to-SUMO pipeline, emission coupling to canyon pollution, and the multi-physics feedback loop that connects all the mathematical models to real-world simulation.
Part Overview
Covers the SUMO microsimulation platform from its core components through car-following models (Krauss, IDM) and HBEFA emission factors to the complete netconvert pipeline from OpenStreetMap. Develops the SUMO-canyon emission coupling and the multi-physics feedback loop connecting traffic flow, emissions, dispersion, and routing in a single integrated simulation.

Chapters
Chapter 1: SUMO Architecture
The SUMO microsimulation platform: core components, network representation, vehicle types, and simulation loop. Derives the Krauss and IDM car-following models and connects to HBEFA emission factor computation for per-vehicle pollutant output.
Chapter 2: OSMnx → SUMO Pipeline
The complete pipeline from OpenStreetMap through OSMnx graph extraction to netconvert network generation. Covers randomTrips demand synthesis, route assignment, and calibration of the simulation against real-world traffic counts.
Chapter 3: SUMO-Canyon Coupling
Couples SUMO per-edge emission output to the street canyon pollution model from Part XVI. Implements the multi-physics feedback loop: traffic flow generates emissions, canyon dispersion computes concentrations, and pollution-aware routing feeds back into vehicle path choice.
