The Interactive Highway Safety Design Model (IHSDM) is a suite of software tools that quantitatively analyze and evaluate safety and operational effects of geometric design decisions on two-lane rural highways. FHWA expanded the IHSDM Crash Prediction Module
(CPM) in 2010 to implement The Highway Safety Manual's Part C (Predictive Method), which highlights predictive methods for estimating the expected average crash frequency of a network, facility, or individual site. The IHSDM contains six evaluation modules:
Crash Prediction, Policy Review, Design Consistency, Intersection Review, Traffic Analysis, and Driver/Vehicle.
The IHSDM course is a highly-interactive training that gives participants the opportunity to use the actual IHSDM software tools to evaluate and analyze real highway designs. NHI recently updated the delivery format and training materials for the course.
The training materials were updated to reflect the expanded CPM. The new delivery format consists of 4 hours of self-paced, Web-based trainings and four 2-hour sessions of virtual, instructor-led trainings, known as Web-conference training.
Upon completion of the course, participants will be able to:
- Explain the scope and uses for the IHSDM tool.
- Input rural highway data to IHSDM.
- Explain the purpose of each of the six IHSDM modules.
- Demonstrate the workflow for each IHSDM module.
- Interpret and apply data from IHSDM reports and graphs to make rural highways safer.
The Using IHSDM Course is designed for personnel working on highway design projects who will be directly interacting with the IHSDM software tools or applying the data generated by them. The IHSDM course benefits highway design project managers, planners,
designers, safety engineers, and other personnel responsible for reviewing operations and safety on rural highways. Participants should have general familiarity with highway design elements and terminology.
