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,...

The uptake of recycled materials in New Zealand’s pavements is currently low. Waka Kotahi NZ Transport Agency wishes to increase the use of recycled materials in pavements to contribute to a circular economy. However, given that transport distances and processing requirements for some recycled materials can be significant, Waka Kotahi wants to identify...

The deployment of autonomous vehicle (AV) technologies may hold health and safety benefits for drivers across the driving lifespan (>18 years of age). However, up until now, the perceptions of such drivers about AVs have not been examined with a combined approach of using surveys and pre- and post-exposure to the actual technology. Lived experiences of...

Previous researchers found that the most important accident causation factor was the driver’s abnormal driving status, which was associated with driving volatility. And the driving volatility can be traced from the trajectories of the vehicles that were embedded in the BSMs. Based on these findings, we developed an automatic safety diagnosis system for...

This project aims to know how the Intelligent Vehicle Technologies (IVT) can improve Vulnerable Road Users’ (VRU) safety in different environments and conditions (e.g., sight distance and traffic flow) at signalized intersections. For the statistical analysis on historical aggregate crash data, the project studied risk factors on crash injury severity for...

Long-span bridges are often used in environmentally sensitive terrains, water crossings, and in locations with traffic and geometric restrictions.   The TRB National Cooperative Highway Research Program's NCHRP Research Report 994: Use of 0.7-in. Diameter Strands in Precast Pretensioned Girders presents the design methodology for precast pretensioned...

Integral abutment bridges have become popular worldwide by eliminating movable shoes which are expensive to purchase, install, and maintain in conventional bridges. However, the behavior of bridge abutments subjected to air temperature changes for integral bridges is different from that of conventional bridges. Expansion and contraction of bridge girders due to...
