First released in 2003, IHSDM has six evaluation modules that help provide quantitative measures of safety performance, check designs against applicable guidelines, and diagnose factors contributing to safety.
IHSDM, which is supported by FHWA's Geometric Design Laboratory at TFHRC, covers two-lane and multi-lane rural highways and urban and suburban arterials.
As a result of the 2010 update, the Crash Prediction Module of IHSDM
has become a faithful implementation tool for the Highway Safety Manual" says Clayton Chen, a highway research engineer on the Safety Management Team in FHWA's Office of Safety Research and Development.
2010 release includes six evaluation modules: crash prediction, policy review, design consistency, intersection review, traffic analysis, and driver/ vehicle.
The 2003 release of IHSDM
culminates a multiyear research and development effort.
The benefit of using IHSDM
for Federal Lands is the same as for any organization.
Targeted specifically to roadway planners and designers, as well as to others in the transportation engineering community, the IHSDM
Web site provides visitors with a complete description of IHSDM
as developing safety software that will provide never-before-available and easy-to-access data to facilitate evaluation of the safety implications of design alternatives.
Other than IHSDM
and ARTS, what are the research needs that might be targeted to rural road safety?
is an integrated system of modules that highway planners and designers can use to evaluate the safety of highway geometric design alternatives within a computer-aided design (CAD) environment.
The design of roadside safety structures is beyond the scope of the IHSDM
as it is now envisioned.
