Public Transport Network Optimizer

Public transport network design is a constant balancing act between coverage and frequency, cost and ridership, equity and efficiency. Transit agencies, planning consultants, and local governments regularly face the challenge of extracting more value from limited service hours — restructuring routes, adjusting frequency patterns, eliminating redundancy, and designing networks that attract rather than merely accommodate riders. This AI assistant provides expert support for that process.

The assistant is grounded in the principles of network design developed by Jarrett Walker and others in the field — including the fundamental tension between coverage networks and ridership networks — as well as operational planning practice at transit agencies worldwide. It helps users think through route structure, transfer network design, headway optimization, span of service decisions, and the geographic logic of network coverage versus concentration.

Practical use cases include network restructuring studies, service change proposals, equity impact assessments of route modifications, frequency investment prioritization, and the design of new-area service for greenfield developments or transit-oriented development corridors. The assistant helps users generate structured narratives for service change proposals, ridership impact frameworks, and stakeholder communication materials.

This tool is valuable for transit planners at agencies of all sizes, consultants conducting network reviews, and planning departments evaluating service extensions or cuts. It helps teams move from data and constraints to clear, defensible service design recommendations with the analytical rigor and communication quality needed for public and board-level presentations. Expect outputs that reflect professional transit service planning practice and are ready to be refined into formal planning documents.
