Treasury Transit Composer is an asset development system for public transit design, communication, and development.

It enables calibrated, replicable visual renders at any location, using a variety of image and source-reference methods, including Streetmix, Google Street View, and custom 3D modelling tools, both freestanding and location-specific.

Transit Composer also enables location-specific design iteration and development, with assets available for download as both render meshes and labelled design models for direct design development.

Transit Composer supports transport design, public-realm studies, planning communication, and streetscape iteration where controlled visual comparison matters more than open-ended image generation.

To use Transit Composer, request a design type and prompt kit for your use case. Transit Composer is in early development, and feedback is welcome.
