DEVELOPMENT OF RISK MANAGEMENT STRATEGIES FOR STATE DOTS TO EFFECTIVELY DEAL WITH VOLATILE PRICES OF TRANSPORTATION CONSTRUCTION MATERIALS (RISK MANAGEMENT SYSTEMS FOR GDOT)

Project Description: 

The overarching objective of this project is to enhance transportation agencies’ understanding of the opportunities, challenges and best practices for utilizing risk management strategies for the asphalt cement price volatility in transportation projects. The final deliverable of this project is a comprehensive risk management guide that systematically addresses risk management for asphalt cement price volatility. The specific research objectives are:

  1. Identify and analyze the latest developments and trends in utilization of risk management strategies for the mitigation of asphalt cement price risk;
  2. Identify key features for the most promising risk management strategies and establish their respective potential benefits and limitations;
  3. Enhance the assessment of risk management strategies considering the strategic objectives of transportation agencies and unique project goals;
  4. Enhance the quantitative assessment of risk management strategies considering their key respective parameters;
  5. Devise appropriate risk identification and allocation matrices for the successful adoption of asphalt cement price risk management strategies; and
  6. Transform research findings into educational and professional development activities.

MANAGING TRANSPORTATION SYSTEM HEALTH: SETTING PERFORMANCE TARGETS AND POLICIES IN NON-UNIFORM REGIONS AND JURISDICTIONS TO ACHIEVE UNIFORM STATEWIDE AND NATIONAL OBJECTIVES

Project Description: 

This project will develop a focused body of knowledge and tools, including a data-and-expert-knowledge-driven approach for addressing a multi-scalar issue involved in performance-based planning at multiple levels of decision making: namely, how to achieve broader national and statewide objectives while taking into consideration regional and local priorities and constraints. The project will apply a multi-methodology analysis to evaluate transportation system health metrics for selected jurisdictions and regions in the state of Georgia and selected states to tell a more comprehensive story about the cumulative impacts of investments at the statewide, metropolitan and local jurisdiction levels, as a basis for determining targets using both quantitative data and expert knowledge in a manner that considers local and metropolitan priorities while aiming to achieve statewide and national priorities.

REAL TIME ESTIMATION OF ARTERIAL TRAVEL TIME AND OPERATIONAL MEASURES THROUGH INTEGRATION OF REAL TIME FIXED SENSOR DATA AND SIMULATION

Project Description: 

A wide variety of advanced technological tools have been implemented throughout Georgia’s transportation network to increase its efficiency. These systems are credited with reducing or maintaining freeway congestion levels in light of increasing travel demands. In Georgia these benefits are primarily gained through the Traffic Management Center’s freeway monitoring and quick response in ridding the roadway of any obstacles that may reduce freeway service levels. There have been a number of efforts to leverage the work done by TMCs to provide travelers with more current traffic information such as Georgia 511 and Navigator. In addition, private efforts and partnerships have made the TMC’s information more accessible to travelers, aiding their traveler decisions. The effort presented in this report aims to compliment real-time freeway information by addressing the more limited availability of real-time arterial performance measures.

ENHANCED ROLE OF ACTIVITY CENTER TRANSPORTATION ORGANIZATIONS IN REGIONAL MOBILITY

Project Details: 

The objectives and tasks of this research are to (1) review the literature and practices on the emerging roles of major activity center transportation organizations in enhancing activity center and regional transportation; (2) survey major activity centers in the United States with respect to their role and activities in actual operations of the transportation system serving their area; (3) support the implementation of road operations strategies under the auspices of the Buckhead CID; (4) assess the feasibility and effectiveness of activity center management association in such strategies; and (5) generalize the results of the research to other activity center contexts in the region and in the United States, with particular attention to Birmingham, Miami and Orlando. The Atlanta region is a good case study site for this study because it is representative of the fast growing metropolitan areas throughout the United States where activity centers play such an important role, and in particular serves as a good test bed for the application of operations strategies, which are receiving more attention in the region.
