Sumo
SUMO es una suite de simulación de tráfico microscópico diseñada para modelar el movimiento de vehículos individuales y peatones a través de redes viales urbanas a gran escala. Funciona como un simulador de transporte multimodal que integra coches, peatones, bicicletas, ferrocarriles y vías navegables dentro de un único entorno, respaldado por herramientas para la generación de redes viales y el modelado de la demanda de tráfico.
El proyecto se distingue por sus conjuntos de herramientas especializados para el análisis de impacto ambiental, que calculan las emisiones de los vehículos y el consumo de energía para flotas eléctricas e híbridas. Proporciona capacidades integrales para modelar vehículos autónomos y sistemas de conducción automatizada, así como un generador de redes viales que importa datos espaciales y definiciones XML estándar de la industria.
El sistema cubre una amplia gama de áreas operativas, incluyendo la gestión de infraestructura de tráfico para horarios de señales, la calibración del flujo de tráfico utilizando datos de sensores del mundo real y la generación de perfiles de flujo de vehículos a través de matrices origen-destino. También admite la simulación de incidentes de tráfico y la creación de dispositivos de detección personalizados para monitorear o influir en el flujo de tráfico.
El software utiliza archivos XML estructurados para la definición de escenarios y ofrece una interfaz externa para el control de la simulación en tiempo real.
