Urban Mobility and Simulation


SEMAPHOR.ai specializes in modeling and simulation of traffic problems. Our method allows to model complex phenomena and to test their impact by simulation. We offer services for road project simulation, deviations in road construction and traffic light programming.
SEMAPHOR.ai relies on staff with more than thirty years of experience in road project management and academic research in the field of traffic theory, simulation and artificial intelligence. We advocate a practical approach that takes account of users' needs, available resources and infrastructure.
SEMAPHOR.ai is working with tools developed by the German Aerospace Center DLR - Institute of Transportation Systems, including the microscopic simulator SUMO developed by DLR since 2001. Our approach is based on experience, academic critical-thinking and current researches.
