It’s About Time: The Transit-Time Penalty and its Racial Implications

Tuesday, May 19th, 2015
Twin Cities Homeownership, Poverty, and High School Graduation Rates, by Racial and Ethnic Group

Transit has many individual and community benefits—from improved safety and cost savings to enhanced personal and environmental health. However, across the nation, trips to work by public transportation take twice as long as trips to work by single-occupancy vehicle. While 68 percent of commutes by people who drove alone last less than 30 minutes, more than half (53 percent) of public transportation commutes are 45 minutes or longer. These travel-mode disparities have racial outcomes: national data show that people of color rely on public transportation for their commutes at significantly higher rates than whites.

The State of Minnesota’s Bridges

Wednesday, May 6th, 2015

The average age of these sub-par bridges is 66 years — well over the typical design life of 50 years and nearly double the average age of all Minnesota bridges (35 years old). More than one in ten Minnesota bridges were built before 1948 — which means more than 1,300 bridges are older than the Korean War and creation of Medicare…Minnesota drivers collectively took close to 628 million trips over deficient bridges in 2014. That’s more than 1.7 million trips per day or almost 1,200 trips every minute taken over deficient Minnesota bridges in 2014.

Figure 1. Saint Paul Supply System Schematic

The primary objective of this study is to understand the relative costs and implementation considerations of different approaches to water sustainability. The northeast metro provides a study area for this evaluation. The Minnesota Legislature requested this part of the metro area to be studied specifically, given the continued concern over lake levels and the interaction of groundwater and lakes in the area, especially White Bear Lake. The study area includes 13 communities. The results will be incorporated in the Twin Cities Metropolitan Area Master Water Supply Plan. The study will be referenced to support future planning of metro area water supplies and water sustainability practices.

These activities are grouped into six categories: improving transit options; accommodating alternative vehicles; supporting pedestrian and bicycle travel; multimodal land use planning; the use of financial incentives to promote multimodal land use development; and other alternatives that do not fit in these five categories.
