About ITE

Data-Driven Safety Analysis Committee

Chair: Mohamad Banihashemi, FHWA, McLean, VA, USA
Vice Chair: Wendy Krehbiel, Kimley-Horn, Jacksonville, FL, USA

Data-Driven Safety Analysis (DDSA) is about employing newer, evidence-based approaches and models that provide highway safety professionals with the methodologies and tools to quantify the safety effects of countermeasures. It also includes methods that could identify high-risk roadway facilities and countermeasures that provide the most beneficial and efficient safety improvements to eliminate fatal and severe injury crashes.

Goals of the ITE DDSA Committee

The main goal of the ITE DDSA Committee is to promote the level of understanding and capability of the safety practitioners, ensuring that all safety professionals have the tools to eliminate fatalities and severe injuries in our transportation system. The ITE DDSA Committee seeks to promote safety for all users of the surface transportation system, including transit users, pedestrians, and bicyclists, as well as promoting equity in the transportation system.

The scope of the activities of the committee is to promote the use of DDSA methodologies and tools to conduct qualitative and quantitative evaluations in all steps of transportation system processes, including:

  • Network screening
  • Diagnosis
  • Crash prediction
  • Countermeasure selection
  • Economic appraisal
  • Project prioritization
  • Safety effectiveness evaluation

Activities of the ITE DDSA Committee

The ITE DDSA Committee works to identify and disseminate roadway safety knowledge to professionals from all over the world. The Committee works to engage agencies, practitioners, educators, and students to improve highway safety in a collaborative manner. Activities developed by the ITE DDSA Committee include:

  • ITE Webinars and Workshops: Development and offering of webinars and workshops have been one of the major activities of the Committee during the past few years. Webinars and workshops can be developed around many different subjects, including but not limited to the following list:
    • Highway Safety Manual components including System Safety Management (e.g., Network Screening), crash prediction models, and Crash Modification Factors (CMFs)
    • Safety in Transportation Planning
    • Human Factors and Highway Safety
    • Safety for All Users
    • Emerging programs such as “Safe System Approach” and “Complete Streets”
    • Emerging Data Sources and Highway Safety
    • Use of Emerging Technologies and Methodologies (e.g., Machine Learning, Deep Learning) in Highway Safety Evaluation
    • Sharing Highway Safety Evaluation Projects and Experiences.
    • Safety Evaluation and Economic Analysis
    • Applying equity principles in project-level
  • Identifying and Presenting Ready-to-Use Tools and Technologies: Emerging programs, technologies, and data sources open a new horizon to be more proactive in highway safety
  • Within-Committee Presentations: The Committee offers presentations during quarterly Committee meetings or on a separate meeting scheduled solely for this purpose.
  • ITE Quick-Bites, Technical Briefs, Informational Reports, and Recommended Practices: The Committee is active in developing ITE technical products.
  • Participation in the Highway Safety Policy and Guideline Development: Participate in the development of policies and guidelines related to highway safety.
  • Communicate with Partners: Engage with organizations such as Transportation Research Board (TRB) and AASHTO Committees targeting contributing factors to data driven safety analysis.
