Multiple layers from the 2014 release of the National Transportation Atlas (NTA) are now available through Community Commons. The US Department of Transportation releases this annual dataset displaying many transportation related features, ranging from highway and airport locations to fatality accident locations and hazardous material transportation routes. The ‘view map’ link displays the motor vehicle fatality accidents. For additional indicators from the dataset, search the Map Room for the term NTA.

This layer displays the estimated percentage of household income for housing and transportation for a family earning the Area Median Income (AMI). The expected values for housing and transportation are modelled by HUD using data from the US Census Bureau and the US Department of Transportation, including:
- The average household size for a family earning AMI in the nieghborhood
- The average number of workers, vehicles, and vehicle miles travelled for a family in the nieghborhood
- The average utility and rental costs or average utility and mortgage costs for a housing unit to accommodate the family size above
- The proportion of housing units that are either rentals or owner-occupied in the nieghborhood
Note: The LAI does not predict what families are actually paying to live in a particular area, but rather what a family would pay (either in USD or as a percentage of income) if average or reasonable housing and commuting conditions for a particular neighborhood were achieved.

This layer displays the estimated monthly cost for housing and transportation for a low-income, single-parent family (earning 50% of the Area Median Income). The values for housing and transportation are modelled by HUD using data from the US Census Bureau and the US Department of Transportation, including:
- The average household size for a single-parent family earning 50% AMI in the nieghborhood
- The average number of workers, vehicles, and vehicle miles travelled for a family in the nieghborhood
- The average utility and rental costs or average utility and mortgage costs for a housing unit to accommodate the family size above
- The proportion of housing units that are either rentals or owner-occupied in the nieghborhood
Note: The LAI does not predict what families earning 50% AMI are actually paying to live in a particular area, but rather what a family would pay (either in USD or as a percentage of income) if average or reasonable housing and commuting conditions for a particular neighborhood were achieved.
