MPC Research Reports
Filter by University61 report(s) found for Utah State University This study evaluated connected and autonomous vehicle (CAV) crash reporting practices across the United States, emphasizing the importance of standardized reporting and legislation for the safe deployment of CAVs on public roads. Through a survey of state transportation officials and a review of current... The I-15 Downhole Array (I15DA) is located near the intersection of I-15 and I-80 in Salt Lake City, Utah. This downhole array is installed in soft soil deposited by Lake Bonneville, where depth to bedrock is expected to be at a considerable depth. The soil conditions at the I15DA are representative... Inductive power transfer systems (IPTS) embedded in concrete pavement panels allow EVs to charge their batteries while in motion. Four prototype concrete slabs were constructed and monitored during high-cycle fatigue loading. After the fatigue tests, each slab was subjected to a static load until failure.... Current electric vehicles (EVs) suffer from several drawbacks that prevent widespread public acceptance. Inductive power transfer systems (IPTS) seek to address range and battery life issues by allowing EVs to charge while in transit. This advancement would allow future infrastructure to meet rising... As roundabouts become increasingly popular, and as many communities promote bicycle use, the safety of roundabouts for people bicycling is of major concern. In this project, we studied bicyclists' safety perceptions of and preferences for roundabouts with different characteristics. First, we performed... With the recent increase in connectivity in vehicle technologies, connected vehicles (CVs) offer a number of potential improvements (e.g., safety, mobility, environmental efficiency, etc.) to the existing transportation system. However, to maximize these benefits, sufficient market penetration of CV... Autonomous vehicles (AVs) that utilize LiDAR (Light Detection and Ranging) and other sensing technologies are becoming more prevalent in the transportation industry. Concurrently, transportation agencies are increasingly challenged with asset management, traffic operations, and safety assessments. The... The use of deicing salts on highway bridges has decreased the service life of bridge decks due to the accelerated corrosion of the steel reinforcement. The use of Glass Fiber Reinforced Polymer (GFRP) in bridge decks as a means of corrosion-mitigation has been met with some success; however, GFRP is... Calcium sulfoaluminate (CSA) cement was used to cast a prestressed voided deck slab bridge girder. The rapid-set properties of CSA cement allowed the initial concrete strength to reach the required 4300 psi needed in order to cut the prestressing strands 6.5 hours after casting. Prestress losses were... When a vehicle drives over a bridge, each bridge girder carries a portion of the vehicle's weight. This load causes strain in the bottom of the bridge girders. However, depending on where the vehicle is located on the bridge, some bridge girders carry a higher percentage of the vehicle's load. This study... |
