TRANSPORTATION INVESTMENT PLAN for the Commonwealth of Massachusetts
2016
Strategies for a robust, efficient, well-functioning, interconnected and flexible transportation system THE
BOSTON AND SURROUNDING CITIES AND TOWNS IS CONNECTED by a variety of roads, biking paths, and public transit services, including rapid transit, commuter rail, bus routes, and ferry services. Nonetheless, as moving away from the central business district, several cities and towns become less served by public transit and less equipped with biking infrastructure, especially those outside of the Route 128 corridor. For instance, places like Peabody in the north, Marlborough in the west, or Plymouth in the south are populous cities where public transit options are scarce or null. This situation forces citizens living or working in these areas to use the automobile as their main, and perhaps only, mode of transportation. As a result, traffic congestion exacerbates in the whole metro area. URBAN CORE COMPRISED BY THE CITY OF

Summary of Estimated Revenues (Millions USD)
The main investment areas lay in bus services, bike infrastructure, information technology systems, EV charging stations, and maintenance programs. As far as sources of revenue is concerned, two strategies would be the key drivers to raise an objective of $1 billion dollars in a period of 5 years: 1) an additional gas tax of 5 cents per gallon, and 2) a congestion charge of 65 cents in all main accesses to the Central Artery tunnel in downtown Boston, the most auto-congested zone of the Commonwealth with a traffic volume of more than 530,000 vehicles per weekday.

Goal 1. Improve the current system’s connectivity Policy 1. Prioritize the expansion of bus services and biking infrastructure Policy 2. Prioritize the adoption of new information technology systems (ITS)
A gas tax scheme and a congestion charge policy would discourage extensive automobile use, but it is equally important to offer alternatives travel modes to citizens. These initiatives are consistent and aligned with the goals of increasing the region’s connectivity, reducing congestion, and lessening environmental impact.
Congestion Charge
The proposed investment plan seeks to stimulate economic development and enhance quality of life across the Commonwealth of Massachusetts through a set of four goals and eight policies:

TRANSPORTATION INVESTMENT PLAN FOR THE COMMONWEALTH OF MASSACHUSETTS Figure 4. Regions in the Greater Boston area with low connectivity to public transit (at least 2 miles away)
Where and why should we invest? The most efficient and sustainable way to connect suburban towns in Eastern Massachusetts to the public transportation network is by expanding the MBTA’s bus service. Buses are more flexible, easier to implement, less contaminating, and require less capital investment than trains or rapid transit infrastructure. In the MBTA’s 2013-2017 Capital Investment Plan only 11.3% of funds were allocated to enhance the bus metropolitan bus service, even though its ridership share was estimated at 29.7% in 2010 (MassDOT, MBTA, 2012).

Regions with low connectivity to the public transit network
The incorporation of 440 new buses to the current MBTA’s fleet and 4 new bus facilities is recommended as part of the new investment plan. The new bus system would serve regions that currently have low connectivity to the public transit system (Figure 4), and would have the potential to add 35,200 new passengers to the daily ridership cipher. This proposed investment aims to connect auto-oriented towns such as Framingham, Marlborough, or Peabody to the existing public transit system and, consequently, to job centers like Boston, Worcester, Lowell or Lawrence. The proposed bus service expansion would cost $351 million. 8
T
2-mile radial distance from train stations
More than 60,000 persons live and work within the regions with low connectivity to public transit that are shown in Figure 4 (U.S. Census Bureau, 2014). Bike paths can offer a healthy and less polluting commuting option for these citizens. In that regard, the investment proposal is to allocate $35 million for the construction of 350 miles of new bike lanes and 1,500 bike racks in these regions. When fully implemented, it is estimated that the new bus services and the new biking infrastructure will reduce the automobile’s travel mode share by 8% in the Greater Boston Area.

Grand Total
Another fundamental component of this investment plan relates to preserving, and modernizing the existing regional transportation system, particularly highways and bridges, public transit stations, electric vehicles charging stations, maintenance facilities, and technological infrastructure. Additional maintenance on rail tracks, boarding stations, and power upgrades are necessary as well. Moreover, aligned with the goal of reducing environmental impact, parking and curbside charging stations are contemplated to promote the
5000
massive use of electric vehicles. To properly address all these latent needs, an investment of $616 million dollars is herein proposed. The cost estimation and a year-by-year plan for allocation of resources is shown in Figure 5. With this investment plan, taxpayers and car users living in suburbs are likely to be provided with additional travel mode choices: bike lanes and buses. Current and following generations will benefit from improved connectivity and mobility, especially those living in urban areas.
It is estimated that the new bus services and the new biking infrastructure will reduce the automobile’s travel mode share by 8% in the Greater Boston Area. Information sources MassDOT / MBTA (2012).

STRONG COMMUNITY INVOLVEMENT IS A KEY INGREDIENT IN THE PLANNING PROCESS to improve the overall livability of a neighborhood, and such has been the case with the JP/ROX Plan: a set of guidelines to enhance open space, mobility, and business development along the transportation corridor between the Bostonian neighborhoods of Jamaica Plan and Roxbury. Starting in July 2015, the Boston Planning and Development Agency conducted several public meetings to assess the community’s vision for the area bounded by Washington St., Columbus Ave., and Amory St. (Figure 1). Perceived already as a rapidly gentrifying area, marked socioeconomic differences across block groups (observed in Figure 1) urge for policies seeking to preserve the character of the neighborhood, make sense of place, foster human connections, and unify the community.

Figure 3. Holistic vision for Sustainable Placemaking: physical and social aspects
Through an extensive planning process of two and half years, the JP/ROX Plan identifies a wide range of elements for the neighborhood that are envisioned by the community, including inclusionary zoning ordinances, mixed use development, maximum building height regulations, late night public transit services, support to locally-owned businesses, among many others. Within the scope of community placemaking, the JP/ROX Plan recognizes the need to address two key community aspirations: 1. Preserve ethnic and cultural diversity, and multi-generational community connections More outdoor events for people from all ages Back allies as pedestrian zones and retail clusters Artist studios and housing Integration of marginalized groups (i.e. Latinos, elders) into new urban development projects 2. Preserve and enhance current green open space Parkways and setbacks, places for kids, youth, adults, elderly to congregate outdoors Eliminate requirement of parking to lower commercial space cost Larger parks on Washington St. Community garden spaces
Short Term Proposals – Phase I
The ultimate objective is to preserve cultural diversity and foster human connections. Figure 2. Community aspirations for a vacant local at the corner of Washington St. and Glen Rd., Boston, MA
With this preamble, three urban design intervention proposals (two short-term, one long-term) are presented based on the holistic vision of sustainable placemaking illustrated in Figure 3 above.

Proposal
More places to sit, walk, bike, eat, and play The main features in all three intervention proposals are more places to sit, pedestrian and bike paths, tree plantings that provide shade, and new amenities such as mini plazas, art and food locals. These simple, inexpensive public assets have the potential to make urban spaces more inviting and attractive for people’s use and enjoyment. Short-term proposals 1 and 2 are considered low-hanging fruits since there would be no major disruption to the current car traffic flow. Proposed interventions at the Southwest Corridor Park are all within the green space area, while modifications in the underutilized Brookside Avenue (between Green St. and Williams St.) would have no major impacts on car traffic. On the other hand, proposal 3 implies impacting a more transited road by closing Green Street to automobiles. This bold yet feasible idea would turn Green Street into a pedestrian pathway that connects the Jamaica Plain and Roxbury neighborhoods. If successful, further pedestrianization projects like Green Street’s proposal would be recommended for McBride, Cornwall, and Boylston Streets. Implementing all these proposals would result in a continuous parkway system (Figure 5), capable of congregating neighbors from all ages, cultural backgrounds, and socioeconomic statuses.

2016 HOUSEHOLD INCOME INEQUALITY Analysis of Suffolk County, MA
SINCE 2010, ECONOMIC INEQUALITY HAS BEEN GROWING IN THE UNITED STATES LIKE IN NO OTHER DEVELOPED COUNTRY. At the beginning of the decade, the gap between the 90th percentile and the 10th percentile of the household income range was represented by a ratio of 6.1, the highest among developed nations (Dreier, 2014). The effects of economic disparity are reflected in a distressed and less functional society. With such challenging preamble in mind, this study investigates if socioeconomic factors, such as educational attainment, race, and family composition, affect the median household income in different census tracts of Suffolk County, Massachusetts. Which social variables have a significant impact on median income? How do variables interact among each other? Is there a statistically significant relationship between them? These are research questions of interest that the present study responds in order to further public policy supported with statistical analyses. Based on literature in the subject, the research hypothesis is that median household income (MHI) per census tract in Suffolk County has a significant positive relationship with the level of educational attainment, the percentage of white population, the percentage of male population, and the percentage of households whose primary language is English. Similarly, it is initially presumed that MHI per census tract in the county may have a significant negative relationship with the percentage of African-American and other minorities’ populations, the percentage of households headed by a single female, and the percentage of population with disabilities.

ANALYSIS OF HOUSEHOLD INCOME INEQUALITY IN SUFFOLK COUNTY, MA
Literature review and relevant facts about income inequality in the U.S. Household income is defined as the total sum of income for members of the household over age 15 (Hartman, 2014). Educational attainment, gender, language and race are highly associated with the level of household income in the United States according to the literature:
Research question, hypotheses, and study variables Research question
Bachelor's degrees earn $2.27 million over their lifetime. Masters, doctoral, and professional degrees earn $2.67 million, $3.25 million, and $3.65 million respectively (Carnevale, 2014). American women make 82 cents to every dollar a man makes, and 80 cents to every dollar made by a white man (Ashton, 2014).
Hypotheses
In 2010 the household income gap between the 90th percentile and the 10th percentile in the U.S. is represented by a ratio of 6.1 (Dreier, 2014).
The gap between the 90th percentile and the 10th percentile of the household income range was represented by a ratio of 6.1 in the United States.
1) There is a significant, positive relationship between MHI and: Graduate / Professional educational attainment (%) White population (%) Male population (%) Households whose primary language is English (%). 2) There is a significant, negative relationship between MHI and: African-American population (%) Other minorities population (%) Female-headed households (%) Population with disabilities (%)
Regardless of gender, African-Americans and Hispanics earn less income than white and Asian people. (Ashton, 2014) Educational attainment among African-Americans and Hispanics is lower in comparison to whites (Ashton, 2014).

ANALYSIS OF HOUSEHOLD INCOME INEQUALITY IN SUFFOLK COUNTY, MA
Data and Methodology Data
Methods
American Community Survey 2014 (ACS 5-Year Estimates 2014) from the U.S. Census Bureau: available data for Suffolk County census tracts Units of observation and units of analysis: Census tracts from Suffolk County Univariate Descriptive Analysis, sample size: 193 census tracts Bivariate Analysis: Correlation between dependent and independent variables Multiple Linear Regression Model
Findings From the univariate analysis, the MHI data has a left-skewed distribution (See left histogram in Figure 1). This is also detected by comparing the independent variable’s mean ($58,401) and median ($53,065) from the summary statistics in Table 1. To correct such deviation the log10 of the median income values is computed, centering the data’s distribution for the dependent variable, as shown by the right-hand side chart in Figure 1. For the bivariate analysis, a cross calculation of Pearson’s correlation coefficients (r) among all the variables of study is computed, using the logged values of MHI as dependent variable. As demonstrated in Table 2, all independent variables have a significant relationship with the dependent variable at the 0.01 alpha level (99% confidence level). As per the Pearson’s correlation coefficients signs, it is confirmed that there is a positive relationship between MHI and education, white population, married-couple households, male population, and English spoken at home. Similarly, there is a negative relationship between MHI and African American, Asian and other race populations, female-headed households, male-headed households, and population with disabilities. 16

All the independent variables proved to have a significant relationship with median household income. Since all the independent variables proved to have a significant relationship with median household income, all of them were included in the multiple linear regression analysis, except for the percentage of African-American population due to its multicollinearity effect with the percentage of white population variable. In the initial multiple regression exercise the ANOVA test shows that the model would be good fit for the data (F = 66.37, sig. 0.000). However, beta coefficients resulted not significant (p > 0.05) for three independent variables: other race population, female headed-households, and white population, as highlighted with blue rectangles in Table 3.

ANALYSIS OF HOUSEHOLD INCOME INEQUALITY IN SUFFOLK COUNTY, MA
Following the “backwards variable selection” approach, the regression model was refined by removing the variable with the highest p-value in every iteration until all beta regression coefficients became significant. This resulted in the elimination of two independent variables in the following sequence: 1) Other race, and 2) Female-headed households. The resulting refined model’s R2 coefficient value is 0.784, which means that 78.4% of the observed variation in Suffolk County’s median household income is explained by the combined linear influence of the independent variables of study. When testing the statistical significance of the regression coefficients (H0: βn = 0) for the refined model, all p-values are less than the alpha level of 0.01, hence all the model’s coefficients are statistically significant at a 99% confidence level. The refined model’s overall fit for the data is also good (F=83.65, sig. 0.000). The model’s equation, able to predict 78.4% of the variation of median household income in Suffolk County’s census tracts, can be expressed as:
Table 5. Summary of results from the bivariate correlation and the multiple linear regression analyses
Log10 I = 3.916 + .005g + .001w – .005a + .009c + .009h + .005m – .006d + .003e + ɛ Significant at the 0.01 alpha level Not significant at the 0.01 alpha level
where I is median household income, g is the percentage of population with graduate or professional degree, w is the percentage of white population, a is the percentage of Asian population, c is the percentage of married couple households, h is the percentage of family households headed by a single male, m is the percentage of male population, d is the percentage of population with some disability, e is the percentage of households where English is spoken at home, and ɛ is the residual standard error. It is important to note that, since the dependent variable is logged and all independent variables are measured in percentages, a 1-unit percent increase in an independent variable will impact the dependent variable by 100 times the amount of its coefficient. For example: the coefficient of the variable g is 0.005, so for every percent unit increase in the population with a graduate / professional degree the MHI in that census tract would increase by 100 x 0.005 = 0.5%. The same logic applies for the rest of the independent variables. Moreover, based on the standardized coefficients’ individual magnitudes, the most important explanatory variable is the percentage of married-couple households (β=0.452), followed by the percentage of graduate or professional degree (β=0.326), the percentage of family households 18
The more family-integrated and the more educated the population of a census tract is, the higher the median household income will be in that census tract. were English is spoken at home (β=0.244), and also the percentage of white population (β=0.165). All this suggests that the more family-integrated and the more educated the population of a census tract is, the higher the MHI will be in that census tract. The ethnicity factor suggests that the higher percentage of white population in the census tract, the higher the MHI will be. In other words: the greater minority population percentage in a census tract, the lower the MHI in such census tract. The analysis also suggests that there is a significant negative relationship between the population with disability and MHI.

MAXIMAZING TRANSIT ORIENTED DEVELOPMENT along MBTA’s Fitchburg Commuter Rail Line
2017
GIS mapping tools to identify sustainable development opportunities around transit nodes AS POPULATION IN CITIES CONTINUES TO GROW, THE CONCEPT OF MEGAREGIONS INTEGRATED BY CLUSTERS OF INTERCONNECTED URBAN CENTERS HAS BECOME MORE RELEVANT as a sustainable way to foster growth, economic development, and better quality of life. The eastern Massachusetts region counts with an extensive network of public transportation in its MBTA commuter rail system. This infrastructure is without a question an extremely valuable asset for the region’s connectivity, offering opportunities for residential and commercial development suitable to the current housing demand. However, how optimal is land use around this valuable public transit nodes? How well utilized is the commuter rail infrastructure that is already in place? The impetus behind this research is to identify opportunities to increase the region’s housing stock by disclosing potential zones that would be apt for transit oriented development (TOD). By means of a spatial analysis of population density and land use patterns along the Fitchburg branch of the MBTA commuter rail system, the ultimate objective in this investigation is to detect possibilities for new housing and commercial development.

MAXIMIZING TRANSIT ORIENTED DEVELOPMENT ALONG FITCHBURG COMMUTER RAIL LINE
Research questions The scope of the study is centered on questions regarding population density, socioeconomic level, and land use. It is through spatial analysis and GIS maps that clarification is sought on the following interrogations with regards to Fitchburg commuter rail line:
Exhibit 1. Classification of land uses selected for the study (left) and customized color code (right) Business and amenities
• • •
Commercial Industrial Urban public / institutional
• High-density (less than ¼ acre lots) • Medium-density (¼ – ½ acre lots) • than Low-density (½ - 1 acre lots) High-density (less ¼ acre lots)
Residential
How is population density in areas surrounding commuter rail stations? What types of socioeconomic levels are found near commuter rail stations? What types of land uses are more prominent around commuter rail stations?
Data and methodology Density is measured in population per square mile at the block group level (2015 ACS Survey), socioeconomic level is illustrated as the median household income at the county subdivision level (2015 ACS Survey), while a color code is used to depict existing land uses (2005 MassGIS data layers). A demographic analysis performed with ArcMap shows choropleth maps for population density and median household income on all corresponding areas surrounding the commuter rail stations of the Fitchburg line. A proximity analysis using ½-mile and 1-mile buffers from the commuter rail stations is performed to exhibit areas with potential for development. Land uses selected for the analysis are classified in three main categories: business and amenities, residential, and new development potential. A color code (Exhibit 1) is assigned to identify those land uses that would be relevant in a re-zoning discussion to promote TOD. Note: This customized color coded is adopted exclusively in this project to visually identify opportunity areas more easily.
• • Medium-density (¼ – ½ acre lots) New• development vacant land Low-density (½ •- 1 Open acre lots) potential • Transitional / Urban open
Findings From the spatial analysis on population density, it is observed that the Fitchburg line serves the least dense commuter rail corridor in the eastern Massachusetts region given that it counts with 19 boarding stations in total. This reinforces the importance of studying land use patterns that surround stations along this transit line. The population density analysis is done at the block group level (Figure 1) with the intention of being as precise as possible when recommending low-dense areas that would be suitable for TOD. Zooming into the commuter line pathway, almost all of its stations lie in areas where population density is less than 2,500 persons per square mile, a very low figure compared to places like Cambridge, Somerville, northern Brookline, and Boston. In that sense, the Fitchburg line potential to increase the region’s housing stock is relevant given market pressures currently experienced in Boston’s metro area due to its economic and population growth. Hence, this is a great opportunity for the eastern Massachusetts region to tap into its existing transportation infrastructure to expand the economic prosperity and wealth creation to those cities and towns situated along the Fitchburg line. Figure 2 shows that all the boarding stations in Fitchburg’s commuter rail line from Kendal Green up to North Leominster could be better utilized, as the areas they serve are low dense. The purple circle surrounding each train stop represents a half-mile radial distance from each stations. 21

Median household income (MHI) is shown in Figure 3 at the county subdivision level because municipal zoning regulations in the state of Massachusetts are established by local governments, hence it makes greater sense to gauge the political viability for zoning reforms and TOD at that scale. The MHI map reveals the wealthiest (green) and poorest (red) areas along the Fitchburg line corridor. This is relevant for the study because the wealthier the county subdivision is, the more politically unfeasible it might be to reform its zoning by-law. High-income residents are associated with greater political power, thus the permitting process to allow more compact, transit-oriented development could become more challenging. Within the line of study, it can be observed that the town of Weston has the wealthiest residents (MHI > $135,000), while Lincoln, Concord, Acton and Littleton fall within a second category ($110,000 < MHI < $135,000). The towns of Ayer, Shirley and Leominster are the least wealthy ($85,000 < MHI < $110,000).
As far as land use regulations is concerned, it can be perceived in Figure 4 how land used for residential purposes goes from high-density or multifamily (green) to medium-density (yellow) in the regionâ&#x20AC;&#x2122;s second ring, to more a scattered low-density (red) in the third ring. But why does residential land use has to vary this way? Why canâ&#x20AC;&#x2122;t there be a more efficient use of land overall? Urban sprawl did not occur organically, but mainly due to codes and standards that impede a smart, compact, and sustainable growth (Duany, 2010). Marked differences can be observed from a transit oriented development standpoint, as the extensive high-density, mixed-use type of development (green) in the city of Waltham is depicted against the extremely low-density, residential development (red) that characterizes the three stations from the wealthy town of Weston. This is a clear example of the political challenges that the eastern region of the state of Massachusetts faces towards a more integral, sustainable growth based on mass transit.
MAXIMIZING TRANSIT ORIENTED DEVELOPMENT ALONG FITCHBURG COMMUTER RAIL LINE Figure 4. Land use (2005) along the Fitchburg commuter rail line.
2. Aim for urban infill development whenever feasible. Select areas declared as transitional or open (vacant) land. If there are no opportunities for revitalizing current buildings, target new development in vacant or transitional land within dense, urban settings that are unsuitable for agriculture or any type of natural vegetation. The best stations for this type of development are: West Concord and Littleton / Route 495.
Fitchburg Line
Map produced by Luis Quintanilla
Policy recommendations Within the scope of this analysis, and based on the land use patterns along the Fitchburg line’s transit nodes, three types of development are recommended in the following order:
1. Make urban revitalization in urban settings. Restore, retrofit or revitalize high and medium-density residential areas first. This includes refurbishing high and medium density housing structures, even low-density housing if this would help increase the number of people living near transit stations. The best stations in the Fitchburg branch for this type of development are: West Concord, Concord, Ayer, and Shirley.
3. Adopt a suburban retrofit approach. Target low-dense industrial or commercial areas first, leave low-density residential areas for last. When neither urban revitalization nor urban infill are possible, go for retrofitting commercial and residential land in low-dense areas. The idea is to get the most out of already taken land; for instance: turning a light-industry site or a big parking lot near a transit station into a mixed-use complex. The best stations for this type of development are: West Concord, Concord, Ayer, South Acton, Littleton / Route 495, and North Leominster.

HOW
CAN WE HELP SENIORS TO NAVIGATE SAFELY IN CITIES AND ENGAGE MORE ACTIVELY WITH THEIR
COMMUNITIES?
More specifically, how can we address the last-mile problem for them? These were prompt questions given at the 2017 Next Generation Mobility Challenge from Toyota and Net Impact, where teams of students from different universities and distinct academic backgrounds share ideas and develop proposals to solve the most vexing mobility issues of today. The winning team gets an internship in Toyota and the chance to incubate its proposal. In this project, I was fortunate to work with a diverse group of students and designed The Smart Cane, an intelligent device that works with GPS, voice recognition technology, and dedicated short range communications (DSRC) to connect users to transportation networks and guide them throughout their journeys. Our main goal in this project is to enhance mobility and confidence for the elderly and individuals with physical limitations by connecting them to people with similar interests and destinations, making their travels secure and fun. The Smart Cane Program promotes autonomy, safety and community building by helping people to navigate in cities with the assistance of artificial intelligence and DSRC technologies, as well as facilitating social encounters, new relationships and outdoor activities. Our teamâ&#x20AC;&#x2122;s pitch was selected as the best proposal in the contest hosted at Boston University on Spring 2017. Figure 1. The Smart Cane Program Team, Spring 2017

Figure 3. The Smart Cane: Product Design
Elder population (65+ years old) will grow significantly:
2 billion worldwide by 2050 = 20% of population Source: United Nations: World Population Ageing.
Our proposed solution would assist the elderly to navigate through public transportation systems in their cities while concurrently connecting them to more people with similar interests and destinations. The latter would help users to socialize and feel safer during their journeys. While designing our product, the team gave a lot of thought to the particular needs of our end user persona (Figure 2): Val, an 85-year-old lady who is gradually losing eyesight and has no family able to take care of her, but she is still willing to do her errands and meet new people to feel accompanied. To that end, we designed a product that is user-friendly, and works with current GPS, voice recognition, and dedicated short range communications technologies that Toyota is investing in. During the prototyping stage, the team conceived a smart device with the form of a cane in order to be handy for senior citizens. Additional variants to the product could be belts, watches or necklaces, so more people would find it convenient.
