Connecticut is aging…
…and Urbanizing
Why is a university research team interested in Title VI compliance?
Motivation
Motivation June 2011: Discussions with Transit Working
Group Title VI & data management pressing concerns
April 2012: Meeting with CTDOT Commissioner August 2012: Begin t-HUB prototype
development November 2012: First Title VI workshop
Lectures, breakouts and survey to ID needs February 2013: Second Title VI Workshop
t-HUB demo & feedback
Why measure equity? Quality of Life (Glaeser et al., 2009)
Higher crime rates in more unequal cities Higher likelihood of political unrest and uprisings People are more likely to report they are unhappy
when living in more unequal cities It’s the law
Title VI of the Civil Rights Act of 1964
It is federal policy Executive Order 12898 on
Environmental Justice

Signing of the Civil Rights Act 1964

Title VI and network planning
Contribute to a sustainable cityPublic transport is an
essential part of urban structure.
Replace auto as primary mode of travel.
Stimulate non-auto activity and community
development.
Provide Efficient TransportGive opportunity to choose between
private auto and public transport.Reduce auto congestion in congested
corridors at peak times by making transit attractive.
Support Social PolicyProvision of service to those who cannot take private auto (captive
riders)
Provide minimum level of accessibility to all members of
society.

Value of Access
Cost of owning an additional vehicle: $6,200/year (Bailey, 2007) $8,000 – 10,000 K/year
(AAA, 2013) A “thrifty” family of four in
the U.S. spends about $6,500 on food every year (USDA 2013)

Equity in connectivity
LIHCO HH (Currie and Senbergs, 2007) 2+ vehicles and
$0-20K HH income
3+ vehicles and $20-30K HH income.
Focus on urban core – reasonable expectation of transit service

Note: Numbers on map represent aggregate number of LIHCO households in each block group for a total of 1,241

Targeted access
Hart and Lownes (in press), Transportation Research Record
Low-income, high vehicle ownership households correlated to a lack of job access and late night service.
