Take-Away Messages
1. Significant gains in transit accessibility to low-wage jobs after the opening of the Hiawatha LRT
2. Accessibility gains not only occurred along Hiawatha but also in areas with bus connections to Hiawatha
3. Significant relocations of low-wage workers to areas near three Hiawatha LRT stations including Cedar-Riverside, Franklin Avenue and Lake Street-Midtown, as well as to areas with bus connections to Hiawatha.
4. Significant reorientation of low-wage jobs to the Hiawatha station areas in downtown Minneapolis and Bloomington’s Mall of America area.

Study Area
• 23,193 transit-served blocks– 1.55 million pop;
– 59% of the 7-county pop.
• 8,921 Hiawatha-connected blocks – direct connection;
– reachable within 30 mins;
– 0.58 million pop;
– 22% of the 7-county pop.

Before-and-After Accessibility Analysis
• Accessibility Measure: the # of jobs reachable within 30-mins of transit travel – Before: 2002 job info with 2000 transit network info– After: 2006 job info with 2005 transit network info
• Mapping the changes– Time-variant transit network (5am; 7am; noon, 5pm, 8pm)
• Estimating the changes base upon regression models– Use distance variables and block demographics to explain
accessibility

Consistency of Accessibility Gains Throughout the Day From 5am to 9pm

Key Findings
• Significant and positive before-and-after changes;
• Major accessibility gains occurred – along the Hiawatha corridor – along the bus routes (especially high-frequency routes) that
connect with Hiawatha
• Consistent accessibility gains throughout the day
10
Regression
• Before Hiawatha– Workers living in
downtown stations areas can reach 47% more low-wage jobs than regular bus station areas.
– South neighborhoods not higher
– Connection areas 112% higher
• After Hiawatha– Downtown 59% higher– South neighborhoods
94% higher– Connection areas 136%
higher

Before-and-After Commuter Flow Analysis
• Estimating changes in the home-to-work BG flow volume
• Based upon– Characteristics of the home location
• Positive coefficients suggest low-wage workers’ relocation to the areas.
– Characteristics of the workplace location• Positive coefficients suggest low-wage employers’ relocation to the areas.
– Socio-demographics of the home BG

Conclusions and DiscussionConclusions and DiscussionPPositive evidence on the role of transit in promoting social equityositive evidence on the role of transit in promoting social equity
1. The Hiawatha impact is regional in scale.
2. To transit planners: • Transit system integration/coordination is essential to the improvement
of accessibility.
3. Low-wage workers and employers are able to take advantage of the LRT, at least in the context of the Hiawatha line.
4. To land use planners: • Balancing jobs and housing: NOT necessarily on the same site
(i.e., balance at the corridor level NOT the station level )
