Denver Regional Transportation District operationalizes accessible ride logistics with Dash

A U.S. metropolitan transportation authority rapidly produces a ride-planning Dash application to assist passengers with disabilities on over 2,000 rides daily.

The Denver RTD helps over 3 million people in Colorado get where they need to go using several different web applications. For passengers with disabilities, The RTD’s Access-A-Ride service is a boon to the most vulnerable Coloradans. The app helps these people get to work, school, and their loved ones. When Incumbent software vendors tried and failed to deliver unique specifications, RTD developers felt Dash empowered them to build out their own solution.
The team was able to comply with WCAG 2.x standards, build unique features supporting the unique needs of their customers, and operate very quickly, often able to push changes to production the same day.
