Sumo: Traffic Simulator - An Introduction (Updated lessons)

Acquire a study area image for Sumo simulation, measure width and height in meters with the ruler, and save the image in project folder with width and height in filename.

Create a network using a pre-modelled study area image as a background to locate junctions and edges for accurate traffic analysis; save and load decals and adjust four-lane edges.

Explore the SUMO network file, a directed graph of roads and intersections, detailing edges as lanes with position, shape, and speed, plus traffic light logics at junctions and lane connections.

Edit and create route files in Sumo, adding trips such as trip_0, trip_1, and trip_2, and learn the four NetEdit creation modes: vehicle, trip, flow, and flowRoute.

Edit the route file in sumo with the vehicle option, creating routes via consecutive and non consecutive edges, color and assign vehicles, then save as demand.rou, and run the simulation.

Learn to edit the route file with the trip option, create multiple trips by selecting edges, set colors and departures, save as demand.rou, and reload SUMO to view routes.

Edit the route file in the Sumo traffic simulator using the flow option to create multiple traffic flows with four options—number, vehsPerHour, period, and probability—and simulate demand with five flows.

Learn how to add decals to a Sumo traffic simulation by loading a decals study area file or editing the Sumo configuration to auto-load a background image across sessions.

Create multiple vehicle types in NetEdit by cloning and customizing presets like bus, motorcycle, taxi, and truck, then define flows and run the simulation.

Learn to resolve bus deadlocks in the Sumo traffic simulator by editing the network in NetEdit, enabling pass for outgoing lanes on deadlock edges, and re-running to verify clearance.

Install sumo and locate the downloads section to access essential microsimulation information. The course supports Windows, Linux, and Mac OS and introduces the two main programs after installation.

Create your first Sumo simulation in five minutes by generating a grid network with net edit, setting a vehicle flow, and saving network, routes, and config files.

Explore nodes or junctions using inspect mode, view edge arrows indicating movements, note id and type (B3), and see eight connected edges; clicking an edge reveals its origin at B3.

Master connection mode in Sumo traffic simulator by editing edge lanes, validating movements, and resolving conflicts to create color-coded vehicle flows; analyze congestion and preview traffic lights in next lesson.

Create traffic lights in a sumo traffic simulation by editing TLS config, adjusting net and route files, and saving networks, while observing congestion and the importance of correct file naming.

Learn to generate and export microsimulation reports from Sumo to spreadsheets, enabling visualization, pattern detection, and infrastructure performance analysis for data-driven traffic decisions.
