Project 1.14: Exploring the Safety Impact of Rumble Strips on Prevention of Lane Departure Crashes in Maine

Exploring the Safety Impact of Rumble Strips on Prevention ofLane Departure Crashes in Maine Project 1.14 Project Summary Enhancing safety of roadway segments is a critical step towards maintaining durable transportation infrastructures. Due to significant costs associated with construction of roadway segments, redesigning or rebuilding a roadway segment is not always a viable solution for […]

Project 2.16: Enhancing the Durability of Bridge Decks by Incorporating Microencapsulated Phase Change Materials (PCMs) in Concrete

Enhancing the Durability of Bridge Decks by Incorporating Microencapsulated Phase Change Materials (PCMs) in Concrete Project 2.16 Project Summary In Rhode Island and other New England states, combined effects of freeze-thaw-induced damage and chloride ingress (from deicing salts) make it very challenging to maintain the quality of concrete on bridges and road surfaces. This project […]

Wireless Joint Monitoring System (w-JMS) for Safety of Highway Bridges Project 1.16 Project Summary The objective of this research project is to develop and deploy a long-term wireless monitoring system on a highway bridge’s expansion joint systems considering environmental factors. Principal Investigator:Dr. Shinae Jang Co-PIs Dr. Song HanDr. Ramesh Malla Institution:University of Connecticut Project:Complete Start […]

Project 1.15: Non-Contact Intelligent Inspection of Infrastructure

Non-Contact Intelligent Inspection of Infrastructure Project 1.15 Project Summary The objective of this research is to develop non-contact sensing mechanism for infrastructure monitoring as well as the associated machine-learning based technique for decision making. Currently available sensory systems for structural health monitoring are almost all based on transducers that are directly attached to or embedded […]

Project 1.13: Structural Integrity, Safety, and Durability of Critical Members and Connections of Old Railroad Bridges under Dynamic Service Loads and Conditions

Structural Integrity, Safety, and Durability of Critical Members and Connections of Old Railroad Bridges under Dynamic Service Loads and Conditions Project 1.13 Project Summary Most of the New England railway bridges were designed and built more than a century ago with outdated design codes and materials. The objective of this research project is to investigate […]

Project 4.12: Proactive and Intelligent Risk Management in Complex Civil Infrastructure

Proactive and Intelligent Risk Management in Complex Civil Infrastructure Project Systems Project 4.12 Project Summary The construction of complex civil infrastructure projects, such as major transportation expansion and rehabilitation, usually faces various types of risks and uncertainties. If not managed properly, these risks and uncertainties bring significant negative impacts on project performance, causing schedule delays […]

Project 1.17: Determining Layer Thickness and Understanding Moisture Related Damage of State-Owned Roads Using GPR and Capturing Such in a GIS-Based Inventory

Determining Layer Thickness and Understanding Moisture Related Damage of State-Owned Roads Using GPR and Capturing Such in a GIS-Based Inventory Project 1.17 Project Summary The Rhode Island Department of Transportation (RIDOT) has a significant inventory of state-owned roads of which layer thickness and moisture related damage is uncertain. Discrete methods of assessment like coring and […]

Project 3.15: Nonstructural approaches to reduce sediment and pollutant runoff from transportation

Nonstructural Approaches to Reduce Sediment and Pollutant Runoff from Transportation Infrastructure in Urbanized Areas Project 3.15 Project Summary Stormwater management is a critical component of transportation infrastructure and reduces sediments and pollutants delivered to waterways. The primary goal of this proposed study is to assess the performance and cost-benefit of including enhanced street cleaning program […]

Project 4.09: Analysis of Covid-19 and Travel In Maine (ACTIME) Validation Study

Analysis of Covid-19 and Travel In Maine (ACTIME) Validation Study Project 4.9 Project Summary The project will support Maine DOT by validating the accuracy of Streetlight Insight® Metrics AADT data using data collected at permanent and temporary count stations in Maine. We are investigating the accuracy of seasonal (monthly), daily and hourly variations in AADT […]

Project 1.12: Improved UAV-Based Structural Inspection Techniques and Technologies for Northeast Bridges

Improved UAV-Based Structural Inspection Techniques and Technologies for Northeast Bridges Project 1.12 Project Summary Unmanned aerial vehicles (UAVs) or “drones” are revolutionizing some basic reconnaissance, including structural inspections. This project seeks to enhance and expand the range of applications for unmanned aerial vehicles (UAVs) to aid inspection of transportation structures. This project is primarily aimed […]
