Road Safety Professional Certification
There have been tremendous advancements in the area of road safety over the past two decades. Practices such as Vision Zero, Toward Zero Deaths, and the Safe System approach have helped foster a culture of road safety in the United States, Canada, and many other places in the world, leading to transportation safety being more widely recognized as a discipline within the profession. These principles are reinforced by local municipalities, provinces, and states implementing data-driven strategic road safety plans, all with the goal of achieving fewer serious injuries and deaths on roadways.

Safety Criteria for Selecting a Smart Corridor: Random Forest Approach using HSIS Data from Washington State
A roadway crash is a multifaceted event involving circumstances such as highway geometry, traffic exposure, operating speed, driver characteristics, vehicle factors, and the interactions among them. Determining the relationship between vehicle operating speed, roadway design elements, and traffic volume on crash outcomes would greatly benefit the road safety profession in general. There is both a need and an increasing trend to use data-driven procedures, such as machine learning approaches, artificial intelligence, and logistic regression methods to better understand the causes behind crashes. Databases like the Highway Safety Information System (HSIS) contain quality data on a large number of crashes and their associated roadway and traffic records consistently across multiple years and states. These databases provide solid resources to perform innovative learnings.

Rural Speed Safety Project for USDOT Safety Data Initiative: Findings and Outcomes
To save more lives and reduce injuries from roadway crashes, agencies must identify sections of the highways that have an increased risk of crash occurrences. Toward that end, the U.S. Department of Transportation's (USDOT) vision for the Safety Data Initiative (SDI) includes the integration of big data sources as a focus area to enhance the general understanding of crash risks and mitigate future crash occurrences. Current crash estimation or prediction methods, such as those in the first edition of the Highway Safety Manual (HSM) use annual average daily traffic (AADT) data along with geometric characteristics to predict the annual average crash frequency of roadway segments and intersections. One inadequacy of the HSM is the limitation of speed-related factors in crash prediction. Recent research has made limited progress in incorporating speed measures (i.e. average daily speed, standard deviation of hourly operating speed) into crash predictive models. To advance the state of the practice, this study begins the work of investigating the association between crash risk and traffic speeds using traffic speed information from big data.

ITE Recommendations on Immediate MUTCD Interim Approvals
Given the current delay in releasing a Notice of Proposed Amendments (NPA) for a revised MUTCD and the lengthy process of adopting a new MUTCD after an NPA is released, ITE suggests the time is right to consider a few immediate interim approvals to move forward with traffic control device standards that improve safety, especially for vulnerable road users.

Developing, Using, and Improving Tables Showing the Safest Feasible Intersection Design
In recent years, the Federal Highway Administration (FHWA) and the states have invested millions of dollars in research on the safety performance of different measures at intersections. Much of this research has been cataloged in an easy-to-use website called the "Crash Modification Factors Clearinghouse"1 maintained by the FHWA. The Clearinghouse contains thousands of crash modification factors (CMFs), which are defined as the ratio of the estimated crash frequency after an intervention to the crash frequency before the intervention. A CMF below one thus means the intervention helped. Happily, researchers have rated the quality of each CMF in the Clearinghouse, on a scale of zero stars (poor or unknown quality, result should not be trusted) to five stars (excellent quality, trustworthy result), so that consumers of the information do not have to make that judgment. The library of CMFs, each with a quality rating, is a tremendous resource.

How Oslo Achieved Zero Pedestrian and Bicycle Fatalities in 2019, and How Other Cities Can Apply What Worked
In 2015 the City of Oslo, Norway made a commitment to reduce car traffic, to prioritize the safety of people on foot and bicycles, and the environment, which came after years of increasing transportation injuries. Unlike in the United States, where transportation fatalities are often viewed as unavoidable, the government of Norway made a strong commitment to Vision Zero nationally, and has worked towards this vision for nearly two decades. Over the last 10 years (2010-2019), Oslo had an average of five to seven traffic fatalities a year. Some U.S. cities of similar size to Oslo, where the population in 2018 was 693,491, have more than double the traffic fatalities in a given year.1

The Road to Zero: Taking a Safe System Approach
"Imagine that, in 2050, not a single person in the United States dies in a traffic crash." This powerful--but hard-to-imagine-scenario--is the premise behind a comprehensive stakeholder effort captured in the RAND report for the Road to Zero (RTZ) Coalition titled, The Road to Zero: Achieving Zero Deaths by 2050.
