MATSim Gridlocks: Problem • “a state of severe road congestion arising when continuous queues of vehicles block an entire network of intersecting streets, bringing traffic in all directions to a complete standstill.” (Oxford English Dictionary, 2014). • Look also at heavy traffic jams • Why: • Gridlocks only roughly covered in current version of microsimulations • e.g., average working day traffic • In MATSim engineered out!
