21-3 Initiating Seed Production for Effective Establishment of Native Plants on Roadsides in New England

Project Objectives

The New England Transportation Consortium funded research to move the capacity of native plant establishment along roadsides from 2013-2016. This work trialed seed mixes and methods for establishment and developed a manual with 39 key species for the region identified. Various protocols for site preparation, seeding, and post establishment monitoring and maintenance were also provided. Following this work, a series of next steps were identified as critical for effective implementation. The most important step was the development of local seed sources, which are currently absent in the region. The shift towards planting native plants along roadsides has multiple benefits including: natural defense for invasive plants, habitat for common and rare pollinator species, and the potential to reduce maintenance needs over time. Pollinators play an important role in this country’s agricultural system as well as in maintaining healthy natural ecosystems.

The problem at hand in the New England is the lack of a native seed mix to use in the roadside habitat that includes important species for pollinators. Also, we do not have a consolidated library of best management practices for roadside management to promote pollinators that apply directly to the climate and conditions in the New England.

This project will include two main efforts. First, it will investigate and develop a list of currently available resources for native seed and plant stock throughout the New England region to understand what is currently available. The study will focus on the list of plant species identified in the 2016 New England Transportation Consortium (NETC) study by the University of Connecticut, “Effective Establishment of Native Grasses on Roadsides in New England” (NETC, 2016), as they are known to suitable to the region and are valuable to pollinators throughout the entire growing season of New England. Once an understanding of what is/is not available, the study will look at ways to increase availability of seeds throughout New England. The study will use gathered information on seed stock to draft a plan for developing a native seed source or sources appropriate for use along New England roadsides. The project would also include proof of concept for developing capacity for local seed source and production for the region.

20-2 Current Status of Transportation Data Analytics and A Pilot Case Study Using Artificial Intelligence (AI)

Project Objectives

The objectives of this research include: (1) reviewing the practices of all DOTs in the New England area and developing a comprehensive inventory of data, data needs, and data analysis practices related to traffic operations; (2) providing recommendations on how to better collect, reduce, achieve, and analyze the data to support DOT decision making and how DOTs should prepare for future transportation data collection and analytics considering emerging sensing and analytical technologies such as connected vehicles, loT, Machine Learning (ML) and AI; and (3) conducting a pilot case study of using AI techniques to automatically analyze specifically-identified operations data and perform a thorough evaluation of its capability to generate useful traffic operation and safety performance measures. This will demonstrate how advanced analytical techniques may extend the capability of traditional traffic sensors and produce additional useful information without expensive infrastructure investment.

19-3 Experimental Validation of New Improved Load Rating Procedures for Deteriorated Unstiffened Steel Beam Ends

Project Objectives

In order to capitalize on the knowledge and methodology developed from ongoing research on new improved load rating procedures for deteriorated unstiffened steel beam ends, the structure of the proposed project will be designed accordingly. The research will identify and quantify the most common beam-end corrosion topologies across states in New England. The goal of this work is to enhance load rating methods for assessing corroded unstiffened beam ends to avoid overly conservative bridge posting recommendations. The new developed methods from ongoing research in the state of Massachusetts calculate more accurately the load carrying capacity. However, the wide application of the new procedures needs to be validated with experiments including several different configurations, beam sizes, corrosion shapes, and support conditions. Laboratory testing will validate and enrich the new procedures while providing valuable insight into the failure mechanisms that control these scenarios. Finally, finite element computational calculations will be calibrated using the produced experimental data from full-scale testing of the corroded beams.
