Tribal Pedestrian Safety
A new video developed by the Center for Transportation Studies highlights a multiyear study of pedestrian safety at reservations that was undertaken by U of M researchers and partners from seven Anishinaabe tribes. The work was sponsored by the Minnesota Department of Transportation (MnDOT).

Using Mobile Device Data to Estimate Bicyclist and Pedestrian Traffic
MnDOT relies on estimates of annual average daily traffic volumes to plan and maintain safe, effective transportation network infrastructure for all travelers. Estimating traffic volumes for nonmotorized road users such as bicyclists and pedestrians has been challenging because monitors are limited compared to vehicle traffic counters. Data from mobile devices, routinely collected through a variety of platforms, offers a potential source of traveler routes. Using monitored nonmotorized traveler data to validate mobile datasets, researchers produced a data visualization tool to estimate bicyclist and pedestrian counts within the Twin Cities area.

New Project: Comparative Analysis of Grade-Separated Pedestrian Infrastructure and At-grade Treatments
Grade-separated intersection crossings allow pedestrians to cross over or under traffic lanes. Several factors determine whether a specific location is appropriate for a grade-separated crossing, such as volumes of vehicle and pedestrian traffic, number of lanes to cross, and vehicle speed and visibility.

Dedicated transit lanes help attract riders, reduce carbon emissions
Public transit systems are instrumental for reducing auto travel and related greenhouse gas (GHG) emissions. But how much of a reduction depends in part on how transit lines operate—on dedicated right-of-way (ROW), in mixed traffic, or some variation.

Transportation challenges for aging rural populations
Reprinted from Catalyst, June 11, 2024
During the past century, a person’s average lifespan has increased dramatically. However, this significant “longevity bonus” has also led to challenges, including how to maintain mobility for an aging population.

Understanding Factors That Influence Driver Yielding to Pedestrians
Vehicle speeds, type of pedestrian, road characteristics and other variables can impact whether drivers yield to pedestrians attempting to cross a road at an unsignalized intersection. An analysis of data collected from 18 intersections identified human and site attributes that correlate to higher rates of driver yielding. Knowledge of these potentially influential factors will help local engineers build safer crossings at intersections.

Enhancing Public Transit with Autonomous Mobility Service to Cover the “Last Mile”
The benefits of public transportation, including reducing individual vehicle use and traffic congestion, aren’t always optimized beyond densely populated urban settings. While transit may extend to more suburban or rural areas, land development patterns can make it challenging for people to reach their destinations by transit alone. Pairing transit with an autonomous mobility service is a potential solution. Researchers assessed transportation needs in a suburban shopping area and developed a system designed to deliver passengers from the end of a transit line to their ultimate destination. Simulations of the autonomous mobility service revealed its potential to increase transit efficiency and reduce individual vehicle use.

Will Hydrogen Be a Carbon-Neutral Fuel Alternative for Freight?
Reprinted from CTS News, March 19, 2024
—Sophie Koch, contributing writer
Hydrogen is getting a lot of attention in recent years as a potential fuel source in the transportation sector. However, it is important to consider the pros, cons, and limitations of this molecule when deciding how to use it.

Safety measures, service improvements key to increasing post-pandemic transit use in Greater Minnesota
Originally published in Catalyst, January 16, 2024
The COVID-19 pandemic took a major toll on public transit and shared transportation services in Minnesota, causing ridership and revenues to plummet. And it wasn’t just an urban problem: Smaller rural agencies and services saw sharp declines, too.
