Stop by the CTS booth at Open Streets on the U of M campus this Saturday, October 1! The event, coming to the U for the second year, will be held on both the East Bank and West Bank from 11 a.m. to 5 p.m.
Open Streets brings together community groups and local businesses to temporarily close major thoroughfares to car traffic and open them up for people walking, biking, skating, and playing.
U of M researchers have developed a way to identify the exact location of “hot spots” for air pollutants created by transit buses—work that could be used to create new strategies for addressing emission hot spots in the future.
The research team, led by Professor David Kittelson of the Department of Mechanical Engineering (ME), began by collecting data using two different instrumented buses, one with a standard diesel engine and automatic transmission and another with a hybrid engine and selectively enabled start-stop technology (both model year 2013). Nitrogen oxide (NOX) emissions and GPS data were recorded for each bus during spring, summer, and fall on an inner city route with frequent stops and slow speeds, a medium-speed route with longer distances between stops, and an express route that required little braking.
While multilane roundabouts almost always reduce fatal and severe crashes, failure to yield and improper lane-use violations can lead to a higher number of minor crashes. To better understand and address these violations at multilane roundabouts, U of M researcher John Hourdos has conducted two studies funded by the Minnesota Local Road Research Board (LRRB).
A new LRRB brochure summarizes findings from these studies and offers highlights of local agency experience to date.
A new report from the Accessibility Observatory estimates the accessibility to jobs by auto in the 50 largest (by population) metropolitan areas in the United States. The report also estimates the impact of traffic congestion on access to jobs in the same areas.
The report—Access Across America: Auto 2015—presents detailed accessibility and congestion impact values for each metropolitan area as well as block-level maps that illustrate the spatial patterns of accessibility within each area. It also includes a census tract-level map that shows accessibility patterns at a national scale. The report is part of the Access Across America study, which began in 2013.
Mumble strips, bridges and waterways, surveying, pavement construction, and highway noise sampling are just a few of the topic areas explored by students in this year’s Summer Transportation Internship Program.
The program, offered jointly by CTS and the Minnesota Department of Transportation (MnDOT), allows U of M civil engineering undergrads to gain real-world experience in transportation and hone their professional skills.
A new video recaps a study that analyzed the mismatch between job vacancies and the unemployed in the Minneapolis-St. Paul metropolitan area.
According to the study, the mismatch between unemployed workers and job vacancies is a serious problem in the region and it appears to have worsened since the turn of the millennium. The biggest concentrations of unemployed workers lack fast or frequent transit service to some of the richest concentrations of job vacancies, particularly vacancies in the south and southwest metro. At the same time, these job seekers may be able to reach many nearby jobs in the metro core but lack the needed qualifications for them.
A special issue of Transport Policy focused on transit investment and land development features papers authored by three CTS scholars: Jason Cao, Yingling Fan, and Andrew Guthrie.
