      <title>Transition to Cellular V2X for Georgia's Connected Vehicles
</title>
      <link>https://rip.trb.org/View/2511181</link>
      <description><![CDATA[This research aims to provide technical guidance for the Georgia Department of Transportation (GDOT) on DSRC-C-V2X transition, ensuring the seamless operation of Georgia's connected vehicles and ITS infrastructure. By addressing this interference issue, the research team aims to pave the way for broader acceptance and implementation of intelligent transportation systems. The significance of this research stems from the limited number of studies addressing in-band interference from Wi-Fi in the 5.9 GHz band due to the Federal Communication Commission's (FCC's) recent order. Notably, these studies that were conducted by relevant organizations such as U.S. Department of Transportation (USDOT) and FCC lack technical details in regard to the bandwidth reduction to the ""upper 30 MHz."

      <title>Coastal Flood Roadway Vulnerability Assessment</title>
      <link>https://rip.trb.org/View/2265647</link>
      <description><![CDATA[The primary goal of this research is to create a vulnerability assessment of Georgia’s coastal roadways to storm surge flooding and sea level rise (SLR).
Objectives are as follows:
(1) Derive roadway crown elevations using the newly released coastal Georgia lidar elevation dataset. This is an improvement to projects in other regions, where the roadway is incorrectly assumed to be the same elevation as the surrounding land (Davis and Dow 2019). 
(2) Perform hydrodynamic simulations for each storm and SLR scenario using a newly updated, high-resolution (20 m resolution in the horizontal) ADCIRC+SWAN model of coastal Georgia. This is an improvement from existing roadway vulnerability assessments. 
(3) Overlay the results from Task 1 and 2 and determine overtopped road sections for each flooding scenario.]]></description>

      <description><![CDATA[This research aims to (1) capture true productivity rates for certain project activities (e.g., asphalt, GAB, grading/earthwork) through benchmarking selected Georgia Department of Transportation (GDOT) projects, and to identify a set of best practices for GDOT to continuously collect and capture true productivity rates in future projects, and (2) to develop a scheduling assistant toolkit for determining a recommended degree of overlapping among project activities. To achieve the goals of this proposal, this research will address the following research tasks outlined in the work plan section below.]]></description>

      <title>Use of “Big Data” and Automated Valuation Models to expedite Right-of-Way Acquisition processes within the Federal-aid program across the nation</title>
      <link>https://rip.trb.org/View/1907195</link>
      <description><![CDATA[The purpose of this research is to compare traditional valuations / appraisals prepared for two completed state department of transportation (DOT) right-of-way acquisition projects in each of three states (Georgia, North Carolina, and Ohio) against the selected automated valuation models (AVMs) valuations of those same properties. The valuations will include estimates for the whole property, and the land unit value conclusions. This research project will result in a report that will inform Federal Highway Administration (FHWA) and its partners / stakeholder agencies about how the use of AVMs may be applicable and appropriate for Federal-aid highway program use.  ]]></description>

      <title>Short-Term Operational Improvement Program Evaluation and Implementation</title>
      <link>https://rip.trb.org/View/1530345</link>
      <description><![CDATA[On suburban and urban roadways, recurring traffic congestion increases delays, makes travel times unreliable, and results in more crashes. Traditional capacity improvement projects involving roadway widening or bypasses may take several years to design, fund, and build, and in the long-term may increase travel demand for the corridor. The Georgia Department of Transportation (GDOT) has begun a highly successful Operational Improvement Program to rapidly identify and address these needs. The program looks for quick fix solutions with lower costs (typically less than $1 million), such as turn lane extensions, minor ITS deployments, and restriping. Projects are sought which have near-term implementation schedules of less than one year.]]></description>
