Lord Mayor Graham Quirk wants Brisbane residents to come forward with their ideas on how his proposed $1.53 billion metro rapid transit system could look and operate.

But Brisbane City Council's Labor opposition has seized on the appeal and accused the Lord Mayor of running out of ideas of his own.

Cr Quirk said the council would reach out to Brisbane residents from next month to seek input to its Brisbane Metro business case, which was expected to be delivered by May next year.

Cr Quirk said the council wanted to know more about commuters' travel habits ahead of the Brisbane Metro's construction, which he hoped would be completed by 2022.
