MPC Research Reports
View AllRailroad accidents can cause economic harm that extends far beyond their own financial losses. As one of the most efficient modes of long-distance freight transportation, losses in line capacity and cargo due to accidents can disrupt the supply chain and lead to commodity shortages everywhere. Therefore... This research seeks to develop an infrastructure safety support system by embedding V2I enabled sensor networks into the transportation infrastructure to provide autonomous vehicles and human drivers with inputs to improve their decision making when obvious decisions may not possible. A new car-following... Gravel road safety is a crucial area of road safety since gravel roads represent a substantial proportion of the entire nation's roadway network. Also, gravel roads pose inherent hazards that are otherwise absent in paved roads. Nonetheless, research related to assessing road conditions for county gravel... The ultimate objective of this project was to determine the structural performance of the dynamic message sign (DMS) bonded with chemical adhesive in terms of ultimate strength and fatigue strength. To achieve this objective, this project first investigated the effects of various parameters (i.e., conditioning... The rise of ridesourcing services such as Uber and Lyft in recent years has revolutionized urban transportation across the globe. With the increased popularity of these services came negative impacts on industries such as taxi cab and public transit services. In an era when ridesourcing companies are... Tracks are a critical and expensive railroad asset, requiring frequent maintenance. Railroads companies often rely on the accurate localization and identification of the track anomalies that could cause serious damage to infrastructure, environment, and the traveling public. However, the deployed method... Academic literature has scant research on sidewalks, and some cities are lacking information to rectify an unprecedented backlog of deteriorating pedestrian infrastructure. A lack of data stymies efforts to understand sidewalks, how they may impact equity, and how cities can prioritize where to begin... 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... Precast concrete construction has been proven to be very efficient in bridge engineering, especially in accelerated bridge construction (ABC), where precast concrete components are connected to save time and minimize disruption of traffic. Post-tensioned (PT) concrete structural elements, when combined... The objective of this study was to simulate the stress-displacement behavior of a flexible debris-flow mitigation structure with a three-dimensional finite element model (FEM). Flexible, steel ring-net structures are becoming state-of-practice for debris-flow mitigation in mountainous terrain. These... |
