Overview

Design Exploration — Participatory Research Framework

Chicago's South and West sides are systematically underserved by the CTA — longer wait times, fewer express routes, and bus networks designed to connect residents to downtown rather than to the jobs, hospitals, and schools within their own communities. This is not a secret. It is a documented, persistent pattern that predates every recent transit plan.

The Transit Justice Atlas is a participatory research and mapping project that makes this inequity visible, legible, and actionable — producing policy-facing deliverables designed for city council engagement rather than academic audiences.

Research Question

"Transit inequity in Chicago is measurable and mapped. The question this project answers is: why has the data not translated into policy action — and what design intervention closes that gap?"

02

The Inequity

Transit access is not distributed equally across Chicago. The gap between the North Side and the South and West sides is structural — built into service frequency, route design, and infrastructure investment decisions made over decades.

2.4×
Longer average peak-hour wait times for bus routes serving Chicago's South Side compared to equivalent routes on the North Side — based on CTA schedule data and real-time tracking variance.
68%
Of jobs accessible within a 45-minute transit commute from Lincoln Park. That number drops to 31% for residents commuting from Englewood — same city, same transit system.
14
South and West Side community areas where the nearest grocery store or major medical facility is more than a 30-minute transit trip — in a city with a comprehensive rail and bus network.
$0
New rail investment on Chicago's South Side in the last 30 years, despite demographic projections showing population growth concentrated in transit-dependent communities.
03

Participatory Method

The Atlas is not a top-down data visualization. It is built around community co-research — residents mapping their own experience of the transit system against the official data. The gap between what the data shows and what residents live is itself a key research output.

01

Community Mapping Sessions

Facilitated sessions in South and West Side neighborhoods where residents map their own transit routes, identify gaps, and annotate the official CTA map with lived experience data.

02

Data Layer Integration

Community input layered over CTA schedule data, Census demographics, employment centers, healthcare facilities, and grocery access — making the structural relationship between transit and opportunity visible.

03

Policy Brief Design

Research outputs translated into policy-facing documents designed for city council presentation — not academic papers. Visual, specific, and structured around decision-making rather than documentation.

Design as Policy Tool

The problem with most transit equity research is not the data — it's the format. Academic papers do not move aldermen. The Atlas is designed specifically for the room where decisions get made, not the room where they get studied.

For City Council

One-Page Equity Brief

Ward-level transit access summary: current service levels, gap analysis, and specific improvement recommendations — formatted for a 5-minute briefing, not a 50-page report.

For CDOT / CTA

Service Gap Maps

Spatial analysis of underserved corridors, frequency gaps, and missing connections — structured to align with CTA's existing planning metrics and budget cycles.

For Residents

Community Atlas

A public-facing version of the research maps — accessible, legible, and annotated with community voice — for use by neighborhood organizations and transit advocacy groups.

For Advocates

Evidence Pack

A structured evidence package combining data analysis, community testimony, and comparative research from cities that have successfully addressed similar transit equity gaps.

05

Deliverables

Maps

Transit Access Atlas

Multi-layer spatial maps showing transit frequency, job accessibility, healthcare access, and community-annotated gaps across Chicago's South and West sides.

Research

Inequity Analysis

Quantitative analysis of service disparities using CTA schedule data, Census demographics, and Chicago Data Portal resources — with community input overlay.

Policy

Policy Briefs

Ward-level one-page briefs and a citywide summary designed for city council presentation — specific recommendations, not general observations.

Method

Participatory Research Framework

A replicable community co-research methodology adaptable to other Chicago neighborhoods or other cities facing similar transit equity gaps.
