The U.S. Federal Highway Administration (FHWA) has released the 2010 version of its Interactive Highway Safety Design Model (IHSDM), which is a suite of software analysis tools for evaluating safety and operational effects of geometric design decisions on two-lane rural highways, rural multilane highways, and urban/suburban arterials, announced the Transportation Research Board (TRB).
IHSDM is a decision-support tool. The 2010 version includes six evaluation modules that cover crash prediction, policy review, design consistency, intersection review, traffic analysis, and driver and vehicle modules.
The updated crash prediction module is designed to serve as a faithful implementation of the recently released Highway Safety Manual’s (HSM’s) Part C – Predictive Methods for two-lane rural highways (HSM - Chapter 10), multi-lane rural highways (HSM - Chapter 11) and urban and sub-urban arterials (HSM - Chapter 12).
September 26, 2010 - September 30, 2010, in Dearborn Mich.
