ITE Technical Brief: Essential Components of Incorporating Safety in Transportation Impact Analysis
The primary purpose of Essential Components of Incorporating Safety in Transportation impact Analysis is to provide information about this evolving and increasingly critical field. While no single method for implementing safety impact analysis is preferred, this document will outline key decisions and tools for agencies and their potential benefits and costs. The intended audiences are agency practitioners and consultants seeking ways to institutionalize safety and fund safety enhancements, including those looking to implement existing safety plans. It is also intended for developers responding to development guidelines and students or young professionals learning about impact analysis practices.

Safe System Strategic Plan
The Safe System Strategic Plan provides a roadmap for the advancement of the Safe System Approach in the U.S. It describes the Safe System Approach, discusses the process involved in building the plan, outlines how to advance a Safe System mindset, and describes steps necessary to implement Safe System practices within the transportation community in the U.S. This plan focuses on the role of road system owners and operators in applying the Safe System Approach to design, build, and operate safer roads. This plan aims to educate transportation professionals on the effectiveness of the Safe System Approach while also offering guidance on how to prioritize safety in the U.S. as a means to achieving zero traffic fatalities.

ITE Quick Bite: Vulnerable Road User Safety at Signalized Intersections
Vulnerable road users-- which may include individuals using micromobility devices such as scooters or bicycles, people walking, people using wheelchairs, or youth and seniors -- make up a disproportionately high percentage of fatalities and serious injuries related to travel. Signalized intersections can be particularly challenging to navigate for vulnerable road users. Fortunately, there are numerous proven safety countermeasures that can be applied strategically to improve the safety of vulnerable road users at these locations.

Recommended Actions to Help Transportation Agencies Implement the Highway Safety Manual
Performance-based processes that use data-driven safety performance measures offer potential for state and local transportation agencies to reduce the number of traffic fatalities and serious injuries that occur on the nation's highways and to make informed decisions to reduce project and operating costs. The American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual (HSM) provides safety knowledge and tools to facilitate improved decision making based on safety performance. The HSM enables transportation agencies to use performance-based statistical approaches when designing for the safety performance of a facility, rather than simply adhering to traditional design policies and standards, such as the AASHTO A Policy on Geometric Design of Highways and Streets and the Manual on Uniform Traffic Control Devices.

The Safe System Consortium: A Call to Action
The Center for Injury Research and Policy at Johns Hopkins University (JHCIRP), known for its leadership in the public health arena, in collaboration with the Institute of Transportation Engineers (ITE), recognized for its leadership in the practice of transportation planning and transportation engineering, recently convened the Safe System Consortium, with support from the FIA Foundation. This Consortium included a diverse group of experts including transportation planners and engineers, public health professionals, safety advocates, academics, researchers, and international road safety experts.

What Type of Crash Can We Expect? Designing for Safety at Common Traffic Control Devices
Lowering crash severity is a critical priority for transportation professionals and all those in the transportation community who are actively adopting Vision Zero. With the goal of reaching zero fatality and serious injury crashes, the need to better understand the factors related to severe cases becomes essential. Crash severity is highly shaped by the crash type, or manner of collision. For example, the odds of being fatally injured in a crash greatly increases for head-on and rollover crashes. Severity has been found to be highest for head-on collisions, followed by angle crashes, and lower for rear end and sideswipe crashes.4 Given this relationship between crash type and severity, it is critical that transportation professionals understand the likelihood of specific crash types to occur at various traffic control devices. A large-scale study in the United States revealing this relationship has yet to exist in literature. This information will guide future decision-making, guiding transportation practitioners to implement the most critical countermeasures to achieve the highest level of safety.

Case Studies on Implementing the Safe System Approach in the U.S.
The Safe System Approach aims to reduce serious injury and fatal crashes by designing and operating roadways in a manner that anticipates human error and accommodates human injury tolerances. Safe System applications vary based on roadway conditions, type, and safety interventions necessary, and they range from separating users in space or time to increasing attentiveness to reducing impact forces. The following case studies outline the Safe System Approach applied on some of the more common types of roadway serious injuries and fatalities in the United States. The case studies outline on-the-ground practices in the following three areas of need: major thoroughfares, intersections, and pedestrians. While few U.S. states or cities are comprehensively using the Safe System Approach, the case studies outline key elements of the Safe System Approach applied by public agencies, both large and small, across the United States.

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.
