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.

Finding High-Performing Aggregate Bases for Long-Lasting Pavement
Two county roads provided a testing ground for three combinations of aggregate bases and asphalt binders. Results from more than two decades of research and monitoring of pavement test sections validated previous conclusions. A larger gradation aggregate base showed superior performance over the pavement life cycle when compared with the standard aggregate base. Additionally, sections constructed without transverse joints to allow natural thermal cracking outperformed sections with sawn and sealed joints.

Effectively Alerting the Public About Local Road Closures
Navigation apps can be valuable timesavers for drivers in Minnesota. To maximize their use, these apps need traffic information that is timely and accurate. While state highway closures are reported effectively, reporting road closures on local roads and highways is inconsistent. This project aimed to improve local road closure reporting by exploring the development of a streamlined reporting system and creating guidance for reporting local road closures to third-party navigation apps.

Managing Stormwater in a Changing Climate Will Require Updates to Minnesota’s Infrastructure
Reprinted from CTS News, March 21, 2024
—Sophie Koch, contributing writer
Changing precipitation patterns caused by the onset of climate change mean that Minnesota’s stormwater management systems—the ponds, pipes, and other structures meant to control runoff in the event of a heavy rainstorm—are going to need an upgrade.
