I am doing my thesis in Smart Awareness System for Drivers using SUMO. I already created a simple network using NETEDIT and know how to create a simulation with random trips. The only part I need help with is creating scenario with certain conditions to show how I can use ITS (Intelligent Transportation System) to communicate cars to have warnings to help increase driver awareness. For example, creating in a simple network, conditions like Traffic alteration (Accidents, Congestion ahead), Climate alteration (Rainy, Snowy Roads) and Road Alteration (Roundabouts, Traffic Lights Ahead, Road bumps etc.). I have later to export data using SUMO simulation and whatever tools/software required to create these scenarios.
