The Importance of Open Simulators and AI in a Changing Mobility Landscape
summary
Claims that open simulators plus AI can tame urban mobility complexity get concrete: digital twins built with Eclipse SUMO power reinforcement‑learning experiments (Flow from UC Berkeley) but real results are mixed — an accident classifier on a 200 km Chinese highway flags ~60% detection from April 2014’s 1,300 crashes yet struggles with rarity and false positives; traffic‑light RL needs heavy compute (one laptop yields 12 episodes in one day while improvements appear after ~20 days) and often produces long cycle times that fail real‑world expectations.
