Transportation & Community Development
A diverse, walkable community depends on a transportation infrastructure that provides a variety of ways to get around, serving pedestrians and transit-riders as well as drivers. Quality of life is key to the success of any urban community. A good transportation network also relies on healthy communities. This can be affected by housing sites, affordable and convenient transportation, easy access to shopping and services, safety and equity.
CNT promotes research and action on understanding housing and transportation affordability, revitalizing and developing communities and public involvement in shaping policy. CNT has worked on a number of projects designed to encourage community development and promote transportation options.
Why is this important?
- Housing plus transportation costs give a more complete assessment of affordability than housing costs alone.
- Transportation costs are driven more by neighborhood characteristics than by the number of people in a household or their income.
- Places with access to services, walkable destinations, extensive and frequent transit, access to jobs, and density have lower household transportation costs.
- Creating neighborhoods with housing and transportation affordability requires multiple and targeted strategies and coordination within and across government agencies and the private sector.
- Underutilized transit station areas present an opportunity to create additional affordable and diverse neighborhoods.

Housing counselors know that their clients need to be prepared for the full cost of owning a home, which includes taxes, utilities, maintenance costs, and other expenses in addition to the mortgage payment. However, some may not have considered the impact that transportation costs have on a family budget, or how these costs are related to where that family lives. Transportation costs represent the second-largest and fastest-growing expense for the typical American family, and they can vary widely based on the location of a home, the size of the household, household income, and other factors.
CNT created the Housing and Transportation (H+T®) Affordability Index to reveal what it costs to get around in neighborhoods across the country. The Index shows that transportation costs vary between and within regions depending on neighborhood characteristics. People who live in location-efficient neighborhoods—compact, mixed-use areas with convenient access to jobs, services, transit, and amenities—tend to have lower transportation costs. People who live in location inefficient places that require automobiles for most trips are more likely to have high transportation costs.
The differences from one location to another can make a big difference in a family’s ability to service a mortgage. The left map below shows that 7 in 10 neighborhoods (69%) in the Chicago region are considered affordable for the region’s typical household when using the conventional measure. On the right, affordability shrinks to 4 in 10 neighborhoods (42%) when using the expanded view of affordability. This produces a net loss of 1,718 neighborhoods where that typical regional family could afford to live.

CNT created an easy-to-use tool called Abogo to put this information in the hands of individuals seeking to make a decision about where to live. Now when families are evaluating their options, they can take into account not only the amount of the rent or mortgage payments and the number of bedrooms they need, but also the impact of the neighborhood on their transportation costs.
Abogo helps clients discover what it costs a typical family in a particular neighborhood to get around—not just for the commute to work, but for all those little trips that make up the bulk of our time in the car: shopping runs, picking up the kids, medical appointments, and so on. You can also use Abogo to compare the estimated transportation cost at an address to the regional average and to find the estimated carbon impact from driving.

CNT recommends that housing counselors use these tools to give clients a full understanding of the costs associated with living at a particular address. You can use Abogo to compare the average transportation costs at different addresses and determine a combined housing and transportation cost estimate for a client, making sure that a home is truly affordable and sustainable for a family. Figuring out transportation costs is a key part of assessing the total cost of owning a home.
CNT also offers a training guide to housing counselors on how to use the H+T Index in their work. It offers the tools and knowledge to help first-time homebuyers and other clients consider how they can control transportation costs while saving for a home, as part of their home-buying decision and to help them stay in their home over the long term. The guide includes talking points for use in one-on-one meetings, a take-home handout for clients, and two slides that can be used in workshop settings. We have collaborated with The Housing Trust of Santa Fe, New Mexico, and the City of El Paso, Texas, to develop these materials, and are currently working to make the guide available in more areas (for more information, contact Stefanie Shull at sshull@cnt.org)
CNT is committed to creating cities that use resources wisely and are affordable for all. Working with housing counselors to provide families the information they need to understand the transportation cost implications of where they choose to live is a key strategy in meeting that commitment.

CNT’s H+T Index reveals the high cost of transportation in nearly 900 regions across the country
CNT has just released the latest version of the Housing + Transportation (H+T®) Affordability Index, using the most up-to-date Census data. While this is exciting news for those who have used the Index in the past, the news on affordability isn’t so bright.
Most places are unaffordable when it comes to combined housing and transportation costs. 72% of American communities are unaffordable for typical regional households when transportation costs—the second largest expense in a family budget—are considered along with housing costs. Under the traditional definition of housing affordability, where a rent or mortgage payment consumes no more than 30 percent of household income, three out of four (76 percent) US communities are considered “affordable” to the regional typical household making their area’s median income. However, under an expanded definition of affordability, where housing and transportation costs consume no more than 45 percent of income, the number of affordable communities decreases to 28 percent, resulting in a loss of 86,000 neighborhoods that are within reach for a typical family.
Transportation costs have risen 39%; much more than income. The analysis also shows that it is much more difficult for the typical household to find a truly affordable place to live today than it was a decade ago, with incomes having increased roughly half as much as transportation and housing costs since 2000. Median housing costs, as reported by the US Census, have increased by nearly 37 percent nationwide, while the national median income has only increased by approximately 22 percent. Average transportation costs in the geographies covered by both Indexes increased by more than 39 percent or $318 per month.
People living in walkable, transit-accessible places are better off. Despite the increase in transportation costs from 2000 to 2009, the Index shows that people living in location efficient neighborhoods—characterized by access to transit, jobs, and amenities—experienced a smaller increase than those living in car-dependent places. The typical family living in a location efficient neighborhood in 2000 (where transportation costs were less than 15 percent of the national median income), saw average transportation costs increase by approximately $1,400 annually. Meanwhile, families living in inefficient neighborhoods (where 2000 transportation costs were greater than 15 percent of the national median income), had average transportation costs increase by more than twice as much, or slightly over $3,900 annually. The difference between these two numbers, $3,900 and $1400 per year, is a benefit of $200 per month “less exposure” to the rising cost of gas during the decade.
CNT used the Index to rank the metropolitan areas that had the highest and lowest average monthly transportation costs for a typical family earning the national median income. Be sure to check out the Index and create your own custom comparisons.

With gas prices already setting records, Congress threatening to cut mass transit funding, and the Chicago region arguably losing its competitive edge, CNT has released a call to action that presents a new vision for building economic prosperity in the Chicago region with an analysis that identifies place-based transportation and community development investments that would reinvigorate economic growth.
Prospering in Place builds on the Chicago Metropolitan Agency for Planning’s visionary GO TO 2040 plan, translating that blueprint into a detailed framework that prioritizes specific places and projects that connect people to jobs.
The report documents how past development patterns have harmed the regional economy. Of Chicago’s 25 top industries, for example, the region is outperforming the nation in only five. Hallmarks of the regional economy—manufacturing, freight, logistics, finance/insurance/real estate, hospitals, and pharmaceuticals—lag behind national performance.
The report shows how to turn that situation around by exploiting the region’s unique assets and advantages: a robust freight rail network, the second largest passenger rail system in the country, vacant land near rail for development, and demographic demand for a vibrant urban lifestyle.
Places matter. But we’ve disregarded the region’s historic, compact, transit-served neighborhoods in favor of urban sprawl, cars, and cheap gas. The cost of this shift was less apparent in good times, but stagnant incomes, high unemployment, and historic fuel prices have exposed its failings.
The analysis prioritizes economic development opportunities based on three strategies: transit-oriented development (TOD), cargo-oriented development (COD), and job centers that need better transit and recommends how to implement these priority strategies.
Moving forward, we need to live closer to where we work, take transit more often than not, and strengthen walkable neighborhoods that meet needs locally. This report shows where and how to begin.
