A/B Street
2025 Update
As of 2025, this project has turned into several others, developed by A/B Street Ltd:
- Network Planning Workspace, a cycle network planning tool
- Low-Traffic neighbourhood tool
- Plan Your Active Travel Schemes for sketching changes to infrastructure
- 15-minute neighbourhood tool for exploring how land use and transportation interact
- Severance Snape to explore
how far walking routes detour to cross big roads - od2net to calculate the most
important roads to prioritize for cycling
Project overview
Ever been stuck in traffic on a bus, wondering why is there legal street parking
instead of a dedicated bus lane? A/B Street is a project to plan, simulate, and
communicate visions for making cities friendlier to people walking, biking, and
taking public transit. We create software to
simulate traffic, edit streets and intersections,
plan bike networks,
create
low-traffic neighborhoods,
and educate the public about
15-minute neighborhoods through games.
The project works anywhere in the world, thanks to
OpenStreetMap.

Project mission
We amplify the efforts of individuals and advocacy groups who campaign to
transition cities away from private motor vehicles. We believe in transparent
and reproducible analysis, so all of our work is open source and based on public
data. We believe everybody should have a voice in shaping their city, so our
software aims to be easy to use.
Why not leave city planning to professionals? People are local experts on the
small slice of the city they interact with daily -- the one left turn lane that
always backs up or a certain set of poorly timed walk signals.
Laura Adler
writes:
"Only with simple, accessible simulation programs can citizens become active
generators of their own urban visions, not just passive recipients of options
laid out by government officials."
Existing urban planning software is either proprietary or hard to use. A/B
Street strives to be highly accessible, by being a fun, engaging game. See
here for more
guiding principles.
