The Urban Transportation Center at the University of Illinois at Chicago has developed the Metropolitan Chicago Accessibility Explorer. The new map-based, interactive visualization tool evaluates metropolitan Chicago's communities' accessibility by car, transit, biking or walking to destinations across the region.

The Accessibility Explorer is a tool for planners and policymakers to explore data and evaluate how well the region's transportation system is connecting people to jobs, parks, shopping, and more. The tool is also intended to highlight for residents how investments to improve transit service, walkability, or land use could affect livability. For example, a visitor can use the tool to create a visualization of the percentage of parks reached in a specified timeframe by mode from a specific location. The Accessibility Explorer was developed with region-wide analysis of travel times for transit, auto, bicycle, and pedestrian modes, and land use data from various federal, state, county, and local governments and agencies. The CMAP Mobility Data Visualizations include a map showing the CMAP Access to Transit Index, which measures the percentage of regional population and jobs with access to transit.
