This study proposes a method for integrating the impacts of climate change and extreme weather events into transportation asset management. It proposes proxy indicators for Iowa that can be adapted for other Midwest states and identifies methods for using those indicators in vulnerability assessments.

This paper uses data envelopment analysis to establish benchmarks for different investment scenarios for highways, bridge, and traffic signage assets.

Following Hurricanes Harvey, Irma and Maria, researchers studied the hurricanes' impacts on supply chains. This article explores the key lessons learned from each affected area and how to mitigate risk in the future.

Guidance is provided on formal justification of customer levels of service from bridges, optimum maintenance and renewals interventions at the bridge level and at network level, and identifying, evaluating and reporting on bridge risk. This Guideline also promotes the concept that formal measurement of asset management performance is beneficial.

The objectives of this research are to document (1) the state of practice within state DOTs as they implement these new requirements and (2) the impacts of implementation to date on asset condition, safety performance and the investment of federal transit funds. This research will provide states with information that will help them evaluate the effectiveness of their efforts to date and refine or adjust their implementation.

2020 saw the beginning of the COVID-19 pandemic and a social movement highlighting racial injustice. As individuals and agencies dealt with the many challenges and adjustments of this time, many of the issues central to transportation also changed. This addendum to the Critical Issues in Transportation 2019 explores the short- and long-term impacts of the coronavirus pandemic on transportation in each of the areas defined in the original report.

The dashboard presents 15 performance measures in the areas of Inclusion, Practical Solutions, and Workforce Development. All of the performance measures support the WSDOT strategic plan. For each performance measure, the dashboard contains information on how successful WSDOT was in achieving their established goal, how it is measured, some background information, and visualizations of their progress over time. The WSDOT dashboard is also notable for its incorporation of diversity, equity, and inclusion metrics as well as workforce development goals.

The VDOT performance dashboard presents with a quick glance the status of five key performance indicators: road clearance times (operations), structure & pavement condition, annual highway deaths (safety), on-time project delivery (projects), and finance. By navigating through the site, users can uncover more details about each of these KPIs including historic trends, maps, per-district breakdowns, downloadable data, and much more.

Idaho Transportation Department presents 11 selected performance measures to provide insight into the condition of the public assets. Their measures are:

• Five Year Fatality Rate per 100 Million Vehicle Miles
• 
Percent of Time Highways Clear of Snow/Ice During Winter Storms
• 
Percent of Pavement in Good or Fair Condition
• 
Percent of Bridges in Good Condition
• 
Percent of Highway Project Designs Completed On or Ahead of Time
• 
Final Construction Cost as a Percent of Contract Award
• 
Construction Cost at Award as a Percent of Budget
• 
Days to Process Vehicle Titles
• 
DMV Transactions Processed on the Internet (in thousands)

On the dashboard homepage, users can easily see the current progress ITD has made on their selected performance measures. After clicking on any of the measures, they can view more information on the measure (including how and why it is measured) and trends over time.

The Missouri DOT performance tracking dashboard contains plentiful information on their selected measures divided into three areas: safety, service, and stability. The tracker is updated each quarter and has data going back to 2005. The dashboard provides a wealth of information on numerous metrics in each category including clean visualizations, a write up of the measure, its purpose, and how data is collected.

The Michigan DOT Transportation Asset Management Council (TAMC) Dashboard features performance metrics in the categories of bridge, pavement, culverts, traffic, safety, maintenance, and finance. For each area, they display a set of graphs indicating the relevant data (such as condition, trends, forecasts, and breakdown by geographic area).

Oklahoma DOT's interactive, GIS-based dashbaord displays their performance measures supporting MAP-21. The website identifies historic trends, includes maps overlaid with data, and tracks the current measures as they relate to ODOT's goals.
