7.1 Transportation Equity
The purpose of the MPO's transportation equity (TE) program is to ensure that populations protected under various federal and state civil rights statutes, executive orders, and regulations (TE populations) are provided equal opportunity to participate fully in the MPO’s transportation planning and decision-making process. The program also ensures that TE populations share equitably in the benefits and burdens of past, present, and planned future transportation projects, programs, and service. The TE program includes three types of activities: 1) outreach to TE populations; 2) systematic consideration of equity in the planning and programming process; and 3) analyses to identify TE populations and their transportation needs, and to estimate the equity impacts of MPO funding decisions.
Environmental Justice (EJ) Executive Order 12898 of February 11, 1994 laid the groundwork for the MPO’s TE program. This executive order required each federal agency to achieve environmental justice by identifying and addressing any disproportionately high adverse human health or environmental effects—including interrelated social and economic effects—of its programs, policies, and activities on minority or low-income populations. The EJ executive order was intended not to create new mandates, but to encourage implementation of existing statutes, such as Title VI of the Civil Rights Act of 1964, which states that, “No person in the United States shall, on the ground of race, color, or national origin, be excluded from participation in, be denied the benefits of, or be subjected to discrimination under any program or activity receiving Federal financial assistance.” Executive Order 13166 of August 11, 2000 extended Title VI national origin protections to individuals with limited English proficiency (LEP).
Because the MPO's TE program grew out of EJ requirements, initially it was designed to serve minority and low-income populations (EJ populations). More recently, in response to Federal Transit Administration (FTA) and Federal Highway Administration (FHWA) LEP requirements and the extension of protections based on age, sex, and disability through the FHWA Title VI/Nondiscrimination program, the MPO is assessing how to expand its TE program to consider systematically the needs of additional protected populations.
TE outreach is an integral part of the MPO's overall public participation program designed specifically to communicate with low-income and minority residents, the elderly, persons with disabilities, and persons with LEP. The purpose of TE outreach is to identify transportation needs of specific populations served by the TE program and promote their involvement in the planning process. Through this outreach, the MPO hopes to develop relationships that will heighten awareness and sow seeds of mutual understanding, appreciation, and trust to encourage broader participation of TE populations.
Outreach targets both individuals and organizations representing the interests of TE populations, such as social-service organizations, community-development corporations, regional employment boards, civic groups, business and labor organizations, transportation advocates, environmental groups, EJ and civil-rights groups, and the state’s regional coordinating councils (RCCs)—recently formed through the Statewide Mobility Management Program to coordinate human-service transportation services.
The MPO maintains an email list of TE contacts to provide them general information about the MPO and its planning processes, and give them information about topics and events of specific interest to the communities served by the TE program. During the past year and a half, staff has worked to increase significantly the number of valid contacts on this list.
Initial TE outreach for the LRTP began in fall 2014 with a series of public meetings to solicit comments on the MPO's revised Public Participation Plan (P3) and inform members of the public about the MPO’s TE program. These meetings were held in areas with high concentrations of minority, low-income, and LEP residents, including Framingham, Lynn, Quincy, and the Fields Corner neighborhood of Dorchester in Boston. The focus of these meetings was to provide information about and solicit input on the P3, which describes the public involvement process for the LRTP and other major MPO documents and activities. These meetings set the stage for specific LRTP public engagement, as the P3 provides information about the LRTP development schedule and the types and timing of opportunities for participation. Subsequent email notifications to the TE contacts kept them apprised of all public meetings for the LRTP and MPO-sponsored meetings at which the LRTP was discussed. Chapter 2 (section 2.6.2) discusses the public meetings and other outreach opportunities specifically for this LRTP.
Notices for all MPO-sponsored public meetings are routinely translated into the three languages, other than English, that are most frequently spoken in the MPO area: Spanish, Portuguese, and Chinese. P3 public meeting notices also were translated into Vietnamese because the Fields Corner meeting was held at the VietAID Center as part of the MPO's effort to forge closer ties with specific organizations as a way of facilitating communication with their constituent populations. Although the email list is good for reaching many groups quickly, MPO staff sees personal contact as a more effective way to foster meaningful engagement in the future.
The MPO systematically integrates equity concerns into the transportation planning process in a number of ways. At the highest level, equity is part of the MPO's central vision statement, and therefore is reflected in the MPO's goals and objectives. Equity concerns are also integrated by considering feedback from all outreach activities, including TE outreach, and the ongoing public involvement that routinely occurs during development of the LRTP, TIP, UPWP, and other MPO studies.
In addition, equity is one of the factors the MPO considers when selecting studies for the UPWP, and it is integrated into the project selection criteria for the LRTP and TIP. Finally, as discussed below, staff performs equity analyses on the recommended projects in the draft LRTP to evaluate the effects on access, mobility, congestion, and air quality for TE populations, and determine whether the recommendations should be changed before a final LRTP is adopted.
The MPO analyzes demographic data to identify the geographic locations and concentration of protected populations. This is done to understand their transportation needs relative to existing and planned infrastructure, and to pinpoint areas where public outreach could be most beneficial and fruitful. For this LRTP, the analysis of benefits and burdens (equity analysis) was based on minority and low-income populations, as defined using federal guidance, census data, and geography.
The MPO region is divided into 1,943 Transportation Analysis Zones (TAZs) for the purposes of forecasting travel behavior using the MPO's regional travel demand model set. A TAZ is a unit of geography that is defined based on demographic information—population, employment, and housing—and the numbers of trips generated in, and attracted to, it. The full geographic area covered by the MPO’s travel demand model set, which also includes municipalities adjacent to the MPO’s 101 cities and towns, comprises 2,727 TAZs.
Using TAZ geography and thresholds established through federal guidance, the MPO has developed demographic profiles that identify areas with concentrations of minority and low-income populations for analyzing benefits and burdens. The MPO has also developed demographic profiles for areas with concentrations of LEP residents, the elderly, and people with disabilities. However, the MPO has yet to develop thresholds for these populations to identify specific areas for the purposes of performing an equity analysis.
The MPO uses the US Census Bureau’s racial and ethnic minority group definitions to determine minority status in the region. The census defines non-minority as persons who identify as white and not Hispanic or Latino. Minorities include:
The FTA Title VI circular (FTA C 4702.1B) defines a predominantly minority area as one where the proportion of minority persons residing in that area exceeds the average proportion of minority persons in the MPO region. Using this definition, a minority TAZ is one in which the minority population is greater than 27.8 percent.
The FTA Title VI circular suggests that a low-income person be defined as one whose median household income is at or below the Department of Health and Human Services’ poverty guidelines. However, the circular allows MPOs to develop their own definitions of low-income, as long as their thresholds meet or exceed the federal definition of low-income. The Boston Region MPO defines a low-income person as an individual living in a household with a median income that is less than or equal to 60 percent of the median household income in the MPO region. The MPO chose this threshold, which is higher than federal poverty guidelines, because the cost of living in the MPO region is higher than the national average.
According to the 2010 census, the median MPO household income was $70,829. Therefore, using the MPO's definition, a low-income TAZ is one in which the average median household income is less than or equal to $42,497.
The MPO uses the above definitions to identify equity analysis zones—TAZs that meet the threshold for minority and/or low-income—as the basis for its analysis of the benefits and burdens of transportation programs and projects. Figure 7.1 shows the MPO’s equity analysis zones, of which 11 percent are low-income TAZs, 33 percent are minority, and 10 percent are both low-income and minority. Also included are the locations of major infrastructure projects recommended in this LRTP.
FIGURE 7.1
Equity Analysis Zones
For the purposes of analyzing the transportation system in 2040, the MPO assumed that the distributions of equity analysis zones would remain unchanged, and that the population growth rate for these zones would be the same as that forecast by MAPC for the overall population of the region. Based on these demographic projections, staff used the regional travel demand model set to forecast the unique distributions of trip flows for the differing transportation networks in the 2040 No-Build and Build alternatives.
To determine whether the benefits and burdens of projects, programs, and service are equitably distributed, the MPO has proposed a policy to measure the following types of disparities, in keeping with federal requirements:
The MPO's proposed policy sets thresholds to distinguish an acceptable level of impact from a level of impact that has a meaningful effect for the factors analyzed. For LRTP equity analyses that are completed using the regional travel demand model set, the MPO has proposed the following thresholds:
Staff proposed a 20 percent threshold based on the belief that a 10 percent differential would be meaningful, plus the model’s 10 percent margin of error. The full disparate impact/disproportionate burden policy will undergo public review and comment before it is adopted by the MPO.
MPO staff used the travel demand model to perform two types of equity analyses (discussed below) each of which calculated differences between the No-Build and Build1 alternatives for equity analysis zones (minority TAZs and low-income TAZs) and the difference for non-equity analysis zones (nonminority TAZs and non-low-income TAZs). For each analysis, the rate of change from the No-Build to the Build alternatives was compared for minority versus nonminority TAZs to determine whether there was a disparate impact and for low- versus non-low-income TAZs to determine whether there was a disproportionate burden.
For the 2040 Build alternative, only major infrastructure projects (those on the recommended list of projects discussed in Chapter 5 and shown in Figure 7.1) were modeled. Specific projects in the O&M-type investment programs are not identified in the LRTP, as they will be selected through the TIP programming process. Because most bike and pedestrian improvements will be part of the O&M-type investment programs, they were not captured in the LRTP equity analysis. However, the TIP project-selection process seeks to minimize burdens and maximize benefits for protected populations, and many projects in the TIP go through the National Environmental Policy Act (NEPA) process, which includes an EJ evaluation.
For the purposes of this analysis, accessibility was based on both the ability to reach desired destinations and the ease of doing so. This analysis investigated the number of employment opportunities, health care facilities, and higher education facilities that could be reached from equity analysis zones and non-equity analysis zones along with average transit and highway travel times to these destinations. Analysis of transit travel times included destinations within a 40-minute transit trip, while analysis of highway travel times included destinations within a 20-minute auto trip.
Staff used the following factors to examine differences in accessibility between the 2040 No-Build network and the 2040 Build network:
For the purposes of this analysis, mobility is defined as the ability to move from place to place, and congestion is defined as the level at which transportation system performance becomes unacceptable because of traffic congestion. The MPO’s mobility and congestion analysis focused on the average door-to-door travel time and average vehicle-miles traveled (VMT) under congested conditions. The air quality-analysis focused on carbon monoxide, a pollutant that results primarily from incomplete combustion of fossil fuels and accumulates in localized areas creating hot spots that negatively affect human health.
Staff used the following mobility, congestion, and air-quality factors in the equity analysis:
The accessibility analysis first compared the change in transit and highway travel times to various types of employment between the 2040 No-Build and Build alternatives for low-income, non-low-income, minority, and nonminority TAZs, respectively.
The second part of the accessibility analysis compared the ratio of the change from the 2040 No-Build to the Build alternative for low-income versus non-low-income TAZs to determine whether there was a disproportionate burden, and for minority versus nonminority TAZs to determine whether there was a disparate impact for each type of employment evaluated. The results of the accessibility analyses are illustrated in the following figures and tables.
Figures 7.2 and 7.3 show that average transit travel times to employment destinations are lower for non-low-income and non-minority TAZs than for low-income and minority TAZs, respectively; but the changes for each type of equity analysis zone between the 2040 No-Build and Build alternatives are insignificant.

Figures 7.4 and 7.5 show that average highway travel times to employment destinations are slightly lower for low-income and minority TAZs than for non-low-income and non-minority TAZs, respectively, but the changes for each type of equity analysis zone between the 2040 No-Build and Build alternatives are insignificant.

Tables 7.1 and 7.2 show that there are neither disproportionate burdens nor disparate impacts in average transit and highway travel times to employment destinations, as all differences fall within the MPO’s disproportionate burden/disparate impact threshold.

The mobility and congestion analyses first compared the change in average door-to-door travel time, congested VMT, and VMT per square mile for all transit and highway trips produced in, or attracted to, equity analysis zones between the 2040 No-Build and Build alternatives for low-income, non-low-income, minority, and nonminority TAZs, respectively.
The second part of the mobility and congestion analysis compared the ratio of the change from the 2040 No-Build to the Build alternatives for low- versus non-low-income TAZs to determine whether there was a disproportionate burden, and for minority versus nonminority TAZs to determine whether there was a disparate impact for each of the factors evaluated. The results of the mobility and congestion analyses are illustrated in the following figures and tables.
Figures 7.6 and 7.7 show that average transit and highway travel times for attractions and productions are shorter for low-income and minority TAZs than for non-low-income and non-minority TAZs, respectively, in both alternatives; but the changes for each type of equity analysis zone between the 2040 No-Build and Build alternatives are not significant.

Figures 7.8 and 7.9 show that average VMT per square mile is greater for low-income and minority TAZs than for non-low-income and non-minority TAZs, respectively, for both alternatives, and that average congested VMT is less for low-income and minority TAZs than for non-low-income and non-minority TAZs, respectively, for both alternatives. However, the changes for each type of equity analysis zone between the 2040 No-Build and Build alternatives are not significant.

Tables 7.5 and 7.6 show disproportionate burdens and disparate impacts for average VMT, and a disproportionate burden for congested VMT. However, because the changes between the 2040 No-Build and Build alternatives for each type of equity/non-equity analysis zone comparison are within the margin of error of the model, it is unlikely that the ratio of the changes is meaningful.
The MPO will carefully monitor these possible burdens and impacts over time and, if necessary, address them at the program level through the TIP project selection process and equity analyses.

Carbon monoxide emissions are essentially the same in the 2040 build network as in the 2040 No-Build network for all zones.
Although the equity analyses conducted for this LRTP look only at impacts on minority and low-income populations, the MPO plans to increase the number of protected populations covered in the future. The FHWA Title VI/Nondiscrimination Program requires MPOs also to consider and analyze equity impacts based on age, sex, and disability. In the coming year, staff will investigate data sources and analytical techniques to determine the most effective and appropriate ways to incorporate these populations into equity analyses.
In addition, the FFY 2016 UPWP will fund a study to evaluate methods for performing more sophisticated equity analyses on the TIP. Such analyses would help to ensure the equitable distribution of benefits and burdens for projects that are not individually listed in the LRTP because they will be funded through O&M-type programs and will be selected through TIP programming.
1 The No-Build alternative includes projects that are currently under construction, advertised for construction, or programmed in the first year of the 2015-2018 TIP. The Build alternative includes the projects that are recommended in this LRTP.
2 Productions and attractions are used in transportation modeling to identify types of trip ends and are loosely related to origins and destinations.
