A Sandwich of Topics

Explore the MATSim Gridlocks issue and its impact on traffic congestion. Learn about the ETH Seed Project's study on congestion events, modeling techniques, and proposed solutions for heavy traffic jams. Understand the significance of managing gridlocks in microsimulations. This book serves as a starting point for new MATSim users, a quick reference for developers, and an in-depth discussion platform for microsimulation methodology. Dive into the world of MATSim and enhance your understanding of traffic assignment and system characteristics.

  1. MATSim gridlock modeling A Sandwich of Topics • MATSim book Andreas Horni IVT ETH Zürich December 2014 • Data management • My 2 cents on career & • job search

  2. 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!
