Reminder about room change: We will be in *CSE2-271* for the talk now, and also in subsequent weeks. *When: Tuesday, 10/8/19, 12pm-1pmWhere: CSE2-271Who: Dustin Carlino* *Title: A/B Street: Fixing Seattle's traffic by playing an open source traffic simulation game* *Talk Summary:*Ever been on a bus stuck in traffic wondering where the bus-only lane is? A/B Street (https://github.com/dabreegster/abstreet) is a game simulating vehicle, cyclist, and pedestrian traffic in Seattle. Players reconfigure road space -- such as changing on-street parking to a bike lane -- and traffic signals, then explore how the change affects different groups. The project aims to bring urban planning to the masses, letting anybody prototype and then propose a small idea for improving Seattle. Attend this talk to learn about the complexities of using OpenStreetMap and other public data to build a detailed road model, how to simulate the movement and interactions of thousands of agents faster than real-time, and about the challenges of building a friendly UI for conveying the intricacies of Seattle's worst jams. *Speaker bio: *Dustin graduated from the CS program at UT Austin in 2014, after working on an undergrad thesis to simulate autonomous cars. He worked on Google Compute Engine in Seattle for four years, then decided to pursue A/B Street full-time. His mission is to find short-term solutions to ease traffic woes in growing American cities, by incrementally improving transit and cycling options. Outside of this project, he helps organize Seattle Jumps, a local parkour community. Contact him at dabreegster@gmail.com.
