MnDOT manages over 50 large safety rest areas (SRAs) with several amenities and travel information centers (TICs) with expanded customer service. Many of the SRA and TIC buildings were built before the significant advancements in energy efficiency and building technology made in the past few decades.

Using AVL/GPS Telematics to Optimize Snowplowing
Republished from MnLTAP News, February 2, 2022.
Automatic vehicle location (AVL) systems using GPS are creating opportunities for local agencies to improve their operations even in real time. A five-page guide and a video from the LRRB highlight the features and benefits of such systems for snowplowing.

Staffing up: Resources to Grow Your Roadway Maintenance Workforce
Local transportation agencies in Minnesota continue to face worker shortages as many struggle to hire and retain employees. Recognizing this challenge, the Minnesota Local Road Research Board partnered with Minnesota LTAP to develop marketing resources for local transportation agencies to use to recruit and retain roadway maintenance workers.

Social Outcomes Improve by Incorporating Arts and Culture into Transportation Planning
Historically, transportation projects have had a disproportionately negative effect on BIPOC (Black, Indigenous and people of color) and low-income communities. Today, state departments of transportation (DOTs) may be able to mitigate these negative effects by reaching out to these communities and incorporating their ideas and feedback into transportation planning. Local artists and culture bearers could serve as ambassadors for these communities by participating in the transportation planning process based on their creative placemaking ideas and connection to the community.

New Project: Use of MNCORS to Support AV Operations in Rural Minnesota
Autonomous vehicles (AVs) have infrastructure requirements such as lane lines, centerlines and intersection signs to guide camera-enabled steering control functions. But many rural roads do not have lane markings or are unpaved, and intersections might be missing components to guide AVs.

Introducing a New Red-Light Running Warning System that Can Potentially Reduce Human Errors at Intersections
Red light violations remain a prominent issue and high contributor to serious crashes and casualties at signalized intersections. An ongoing research project, funded by the Local Road Research Board, and Federal Highway Administration (FHWA) State Transportation Innovation Council (STIC) Incentive program, is developing and testing a warning system that signals drivers as they approach a red light and prompts them to decelerate.

Using Alternative Technologies to Detect Vehicles at Signalized Intersections
In Minnesota and across the country, the most common traffic signals are those that are actuated by a device embedded in the road that detects the presence of a vehicle at the intersection. While these embedded devices can last for decades, they don’t always detect modern vehicles, such as electric cars, or vulnerable road users, such as bicycles or motorcycles. New research evaluated the performance of video- and radar-based detection systems, which are becoming more readily available, under a variety of Minnesota weather conditions.

NCITE Webinar: LRRB Mini-Roundabout Guidance
Tuesday, August 6, 10-11 a.m., free to attend
Increasingly, local agencies are opting for mini-roundabouts for some locations instead of traditional roundabouts, which typically require a larger footprint than a standard four-way intersection. Mini-roundabouts are characterized by a small diameter and fully traversable islands (central island and splitter islands).
Join the Apex Engineering Group for a presentation on the Local Road Research Board project, Mini-Roundabout FAQs. Project team members Michael Marti and Zach Heimer with SRF Consulting Group and Jon Pratt with the City of Detroit Lakes will discuss this new guidance.
The guidebook defines mini and compact roundabouts and provides selection criteria on when to use them as well as details regarding the center treatment. The FAQ format provides easy navigation to technical information.
