Prototyping Chicago Bus Rapid Transit

Prototyping Chicago Bus Rapid Transit (Fall 2008)

Abstract

In 2009 the Chicago Transit Authority, CTA planned to launch a high speed bus service. The Bus Rapid Transit, BRT service is based on 60 feet long, newly configured, articulated buses. Key features of the system include: improved fare handling through multiple entry points, select station service, and right-of-way signal prioritization electronics. By using rapid prototyping methods we provided key decision makers with the ability to evaluate and change the design of the vehicle interior improving expected passenger flow by reducing bottlenecks, enhancing the riders’experience, and improving bus operations.

Overview

A full-scale low fidelity mock-up was built in a day from stacking chairs, foamcore, blue tape, particle board, bar stools and a few print-outs. With this, the seating layout for the bus was defined. Upon review by the CTA‘s senior team, shortly before the seating plan was to be released for production, the seating plan was reconfigured to decrease rider bottlenecks and improve speed of service. Brainstorm ideas were quickly mocked-up to convey new ideas, such as a means to designate your stop in advance through the use of a smart card.

In addition, an 8 foot long scale model was completed to visualize the interior design of the bus. The model served as a focus for discussion by the expanded CTA team consisting of managers from all areas of the organization. Potential floor plans, seating, and stanchion details were made concrete and debated. The CTA also used the model to improve its communication of key characteristics of the BRT buses to Mayor Daley and city government officials.
