MPC Research Reports View AllConnected and automated vehicle (CAV) driving features can impact traffic safety in many aspects owing to their improved driving behavior. On the other hand, road geometric design elements are mainly based on human reactions and behavior, which might affect safety depending on road layout and the parties... This study evaluates a comprehensive experimental investigation to better understand the mechanical and deformation behavior of Wyoming bedrocks and therefore to improve the design and construction of transportation infrastructure. Fifty-six rock samples were collected from different locations around... The existing parking system assumes that drivers can pay the right price for parking, but we find the opposite in a field study (N=567). Drivers either overpay or underpay for parking at on-street parking meters 98% of the time, for 20–30 minutes on average. Such misalignment between parking payments... For decades, work zone traffic safety under adverse weather conditions has been a serious concern for drivers and transportation agencies. Natural hazards often cause disruptions on roads and bridges and work zones during the retrofitting process. Existing studies on work zone traffic safety with statistical... Airport operational data are necessary for aviation decision-makers to quantitatively prepare airport master plans and fairly distribute national funds throughout the country. These data have other important applications, such as safety and security applications. Interestingly, most airports (i.e., typically... This study aims to improve the efficiency of driven piles in intermediate geomaterials (IGMs) to increase the reliability of pile foundations for bridge structures. Test pile data collected from the seven state DOTs and total 223 pile load test data are evaluated to provide recommendations for driven... This report presents several advancements in the empirical modeling of liquefaction-induced lateral spread. It starts with a newly collected dataset of 5,560 historical lateral spread displacement vectors, a sample size over 10 times larger than the existing databases and subsurface data comprising over... Understanding the condition of roadway assets is important for transportation agencies to plan for future improvements and asset management purposes quantitatively. Since these assets are distributed across the country, a manual data collection system falls short of the automated methods due to time... The use of precast concrete in bridge construction has been abundant in recent years because of its efficiency and superior quality control. Precast components are connected at the bridge site to reduce construction time and traffic disturbance. The Grouted Splice Sleeve (GSS) connection provides good... Connected and Autonomous Vehicle (CAV) technologies enable communication among vehicles, and vehicles and infrastructure, paving the way for multiple safety and operational applications. This research developed and tested traffic signal control algorithms and control programs, which utilized CAV-equipped...
