Welcome to the redesigned RTAMS (Regional Transportation Authority Mapping and Statistics) website, a collection of tools for accessing extensive data resources about the six-county metropolitan Chicago region’s transit system. Developed and maintained by the Regional Transportation Authority (RTA), the website is currently under construction and is in Beta format. The site will be updated throughout 2020.
