Hi! https://a-b-street.github.io/docs/project/history/retrospect... has a summary of where the project went. The original scope of the traffic simulation was too grandiose, and it was hard to influence real decision-making with something so complex and buggy. A/B Street morphed into several simpler tools focused on specific problems (removing through-traffic through an area, estimating uptake of new cycle lanes). I'm focused more on web-based tools for gov use these days, but will get back to simulation someday!
