Snow and ice can easily accumulate on the lenses of signal lights and block light to the drivers of vehicles or locomotive engineers. Snow-clogged signal lights can decrease the performance of signalized intersections and railroads and may result in collisions in inclement weather conditions. The TRB IDEA (Innovations Deserving Exploratory Analysis)...

On September 28, 2021, City of Ottawa staff approved the Protected Intersection Design Guide technical guidance document under delegated authority. The purpose of this document is to provide guidance on the design of protected intersections within the City of Ottawa. The Guide aligns with current legislation, regulations, and high-level policies, and builds...

Minnesota’s harsh climate requires dense, durable asphalt to avoid frequent maintenance and replacement. Asphalt mixes as designed in the laboratory, however, don’t always perform consistently in the field. A new Superpave mix shows promise for providing cost-effective, high-performing pavements for state roadways. The project description and links...

Motorists suddenly stopping or swerving to avoid small animals crossing the road create significant hazards. Pedestrians trying to assist the animals across the road risk serious injury, as do motorcyclists and bicyclists if they hit an animal. Turtles are the world’s most imperiled group of vertebrates, and roads are a primary threat. A multiyear...

A cost-effective and environmentally friendly asphalt repaving method will now be more efficient. Cold in-place recycling (CIR) involves pulverizing the top layer of old pavement, mixing it with water and a stabilizing agent such as emulsified asphalt, and reapplying the mixture to fill in holes and cracks. A final layer is added to seal and preserve the...

School and public transportation buses subjected to recurring congestion delays result in these modes becoming both more expensive to operate and often less-competitive as mobility options. Maintaining existing coverage and frequency requires increases in operating and capital expenses. Failing to maintain coverage and frequency encourages mode shifts which may...

This report presents the results of a mixed-methods study of the 2020-2022 Oakland Slow Streets program. An official response to the Covid-19 pandemic, the program used signs and temporary barricades to limit thru-traffic on 21 miles of city streets to create more and safer space for walking, cycling, and outdoor recreation. Researchers collected data...

The majority of traffic count portable data collections is done by road tube. While the hardware unit costs for road tubes are low, installation requires workers to kneel in the middle of the road sujecting them to potential harm. The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 216: A Portable Single...

This project focused on the development for the integration of unmanned aerial systems (UASs) and artificial intelligence (AI) to automate planning, monitoring, and performance verification of highway maintenance tasks within the Georgia Department of Transportation (GDOT). The current mowing assessment for verifying the performance of mowing contractors was...

Environmental conditions are considered an important factor influencing asphalt pavement performance. The addition of modifiers, both to the asphalt binder and the asphalt mixture, has attracted considerable attention in potentially alleviating environmentally induced pavement performance issues. Although many solutions have been developed, and some deployed,...
