The objective of the study was to evaluate the safety effects of two countermeasures with respect to vehicle–pedestrian crashes—the provision of protected or protected/permissive left-turn phasing and the provision of leading pedestrian intervals (LPIs)—using a before–after empirical Bayesian methodology. The study used data from North...

Ultra-Thin Bonded Wearing Course (UTBWC) pavement surfacing was introduced to Minnesota in 1999 under the brand name, “NovaChip”. It was developed as a preventative maintenance option to extend pavement life by placing a thin open/gap-graded hot mix asphalt (HMA) lift over a polymer-modified asphalt emulsion. The open/gap-graded aggregate also...

This report presents corrosion study findings related to corrosion resistance of eight types of metallic dowel bars. The accelerated laboratory corrosion testing was performed using seven small-scale concrete slabs that simulated typical concrete pavements for 452 d of a modified Southern Exposure followed by a detailed autopsy of the extracted bar samples. The...

Introduction and adoption of autonomous vehicles (AVs) will likely reshape the transportation system and many economic activities. The economic literature on technology adoption can provide lessons on the diffusion of AVs as well as the social and economic impacts. We rely on the threshold model of diffusion, where heterogeneous agents make decisions to pursue...

Data is essential for understanding the demands placed on road assets and transport networks. There is an opportunity through advances in real-time technologies to improve the delivery of network management and asset management activities. This requires an understanding of both the real-time technologies that are available, and the real-time information needs...
