Rear-end crashes are a major cause of highway traffic slowdowns, and preventing these congestion-causing incidents requires a clear understanding of why they occur in the first place. On the surface, it might seem like the driver who rear-ends another vehicle is the primary cause of the collision; however, the reality is much more complex.
In a new study, U of M researchers found that because shockwaves—areas of suddenly stopping or slowing traffic—are usually the cause of rear-end collisions on highways, drivers at the front of a group of cars may have as much or more to do with the rear-end collisions happening at the back of the group than those involved in the crashes themselves.
As of the end of June, five members of the CTS Executive Committee will have completed their terms of service.
CTS would like to thank these departing members for their dedicated service and support to the Center and the University.
For several generations, transportation policymakers and practitioners have favored a “mobility” approach, aimed at moving people and vehicles as fast as possible by reducing congestion. However, the limits of this approach have become more apparent over time, as residents struggle to reach workplaces, schools, hospitals, shopping, and numerous other destinations in an equitable and sustainable manner.
Researchers have been able to define this challenge more precisely and elevate the importance of “accessibility” over the past few decades, but the adoption of new policies, tools, and investments by practitioners remains slow and uneven across most regions. During CTS’s 2017 Spring Luncheon presentation, Brookings Institution fellow Adie Tomer offered highlights from the institution’s Moving to Access Initiative, which visualizes challenges of the current mobility model, impediments to adopting an accessibility-focused approach, and a vision for where metro areas can go from here.
We’re in a period of rapid demographic change—and that will have significant implications for Minnesota’s workforce, including in the transportation industry.
As Minnesota’s population continues to age for the next two decades, its emerging workforce will be more racially and ethnically diverse than those retiring. In a session at the Minnesota Airports Conference this spring, Peter Mathison with the Wilder Foundation shared these and other insights on Minnesota’s current population make-up and predictions of where it’s headed in the next 20 years.
Light-rail transit (LRT) is commonly thought to stimulate economic development and boost property values. However, knowledge gaps have made it difficult to gauge exactly how much property values increase and when the increase happens.
In a new study, U of M researchers Jason Cao and Shengnan Lou help fill those gaps. Using tax parcel data and modeling techniques, they assessed the impacts of the Green Line LRT on sale prices of single-family houses near station areas in Saint Paul. They also examined when the value uplift occurred, focusing on two key time points—before and after the Federal Transit Administration’s announcement of the full funding grant agreement (FFGA) in April 2011, and before and after the start of Green Line operation in June 2014.
Transportation funding comes from all levels of government—federal, state, and local. Funding that is directly generated by local taxes and fees stays in corresponding local jurisdictions (counties, cities, and townships, for example). Federal and state transportation funding, however, is allocated through certain budgetary procedures and may not be used in the original point of collection. How are these transportation funds redistributed in Minnesota? An analysis from U of M researchers offers new perspectives.
For the study, which looked at the six-year period between 2009 and 2014, the researchers analyzed funding revenues and expenditures at the district level (see map of Minnesota’s eight districts) for both roadways and transit.
A new 10-episode podcast is exploring what commuting in the Twin Cities is like—and what it could be.
Here to There, developed by Apparatus and Transit for Livable Communities & St. Paul Smart Trips, examines the inextricable link between the ways we commute and the ways we live.
Each episode focuses on a different “destination”—defined not as a place but as a goal for the Twin Cities mobility system. Episode destinations include accessibility, equity, cohesion, and flexibility.
