Rethinking how cities
plan their transit

Transit Planner is a web-based tool for drafting transit routes and stops on an interactive map, iterating quickly, and exporting your sketch as a valid GTFS feed β€” with an AI planning council to pressure-test every proposal.

Built for planners

Designed around the real workflow of transit planning β€” from initial corridor sketches to detailed stop-level analysis.

🧠

AI at the core

Multi-agent AI evaluates every route you design, surfacing insights that take analysts weeks to compile.

🌍

Open & interoperable

First-class GTFS support means your work plays nicely with every major transit planning platform.

Features

Everything you need to plan transit

From first sketch to exported GTFS feed, Transit Planner covers the full planning workflow.

Interactive Map Editor

Draw transit routes directly on a live Mapbox map. Place stations, define corridors, and visualize your network in real time.

AI Planning Council

Five specialized AI agents evaluate ridership potential, coverage gaps, transfer efficiency, and neighbourhood impact in a structured debate.

Population & Traffic Data

Overlay census population density and traffic patterns. Instantly see how many people your proposed route will serve.

GTFS Import & Export

Import existing GTFS feeds to visualize real transit networks. Export your designs in standard GTFS format with built-in validation.

Neighbourhood Intelligence

Click any area to see population density, traffic levels, employment data, and street-level context β€” all in one place.

Lines & Stop Management

Organize routes by mode (subway, streetcar, bus). Toggle visibility, edit stops, and manage custom lines with undo/redo support.
