A/B Street is an open-source traffic simulation and urban planning tool that models how cars, bikes, and pedestrians move through real-world street networks. It imports data from OpenStreetMap to build detailed, lane-level road models, then runs discrete-event simulations to analyze travel times, delays, and congestion patterns across different infrastructure scenarios. The project provides an interactive map editor for modifying road geometry, lane configurations, traffic signals, and access restrictions, with full undo/redo support. Users can design low-traffic neighborhoods by placing moda

Omim is a suite of compilers and orchestrators designed to transform raw geographic and transit data into renderable offline map binaries. It provides a map generator for converting OpenStreetMap data into optimized binary files, a styling compiler for visual feature representation, and a rendering engine for visualizing geographic data from local storage without an internet connection. The project includes a map tile build orchestrator that sequences generation and optimizes resource utilization based on historical statistics. It also features a dedicated transit data processor that transfor
