Our work matters

HSRC researchers and staff work to figure out how to save lives and reduce injuries on our roadways. Our projects are designed to support transportation professionals across the globe as they work toward that same goal.

Areas of expertise

Improving traffic operations and roadway design

Engineers, planners, and administrators are constantly striving to design, build and operate a roadway environment that is both safe and efficient. HSRC researchers are at the forefront of understanding how the safety of all road users is impacted by the array of design elements and traffic control devices that are present on our streets and highways. This knowledge is transformed into guidance and decision-making tools that enable safety practitioners to get the biggest effect for their safety dollar.

Reliable and robust data are at the heart of all HSRC safety research. The Center has long been involved in the development, implementation, and management of data systems to support safety research.

Changing behaviors

Humans are remarkably complex. People don’t always operate the way we think they will, and their behavior is not easily changed. This reality is a challenge for transportation safety.

People make a multitude of decisions over the course of a single trip on a roadway, whether by vehicle, foot, or bicycle. And safety is often a direct result of chosen behaviors, such as: wearing a seatbelt; driving at the appropriate speed; properly restraining a child in a car seat designed for their height and weight; or walking in a crosswalk. HSRC researchers study how behavior and safety interact in the real world.

In recent years, the transportation safety field has evolved toward naturalistic driving data – which is the collection of data without manipulation of the environment. HSRC has been involved in both the development of analysis-ready databases that include these new data elements, and research using these data to better understand behaviors of drivers and passengers.

HSRC researchers were at the forefront of using in-vehicle camera technology to directly observe driver behavior, most recently distraction among young drivers. This naturalistic data has also been used to study interaction between parents and teens during supervised driving. In addition, HSRC has used naturalistic driving data to study roadway curvature and alignment to understand how to best design roadways.

Improving pedestrian and bicyclist safety

The desire to increase the number of walking and bicycling trips combined with a record number of vehicle miles driven has created increasing concerns. HSRC has long been involved in pedestrian and bicyclist safety and mobility research and it remains a priority – and area of expertise – for our staff.

Programs run by HSRC – including the Pedestrian and Bicycle Information Center and Vision Zero for Youth, and projects like Walk, Bike & Roll to School Day – have helped pave the way for safer walking and cycling environments and more transportation choices for all.

Applying a Safe Systems approach

HSRC applies public health principles and systems science in our work to equip current and future transportation professionals and stakeholders with more effective tools to solve complex safety challenges.

A Safe System approach is built around six principles, and should be designed to: • Adapt the system to human behavior • Manage kinetic energy • Treat safety as the foundation for all interventions • Create a shared vision and coordinate actions • Explore system gaps and interactions • Provide frameworks for community engagement and risk management

Multidisciplinary collaboration is the bedrock of creating a Safe System. Multidisciplinary work by many – researchers, policymakers, private industry, safety non-profits, and multiple other stakeholders — advances safety for all road users.

Developing the transportation profession

Throughout our 60 years of existence, HSRC has made a special effort to share our expertise and research with communities, students, researchers, and practitioners. By assisting with public requests for safety information and data per year, presenting at conferences, and publishing research findings in journals and other publications, HSRC staff continues to promote multi-disciplinary interest in highway safety.

HSRC’s training and education arm, the Road Safety Academy, makes transportation safety education more accessible than ever before by offering both in-person and web-based trainings that cover a broad range of safety topics. In addition, our work includes coordinating dozens of free webinars each year for researchers and practitioners, and developing teaching modules for university courses being taught in engineering, planning and public health schools.

HSRC continually works to develop tomorrow’s transportation safety professionals by integrating students into our research work.
