|Project Name:||Interactive Highway Safety Design Model|
|Start Date:||September 12, 2008|
|End Date:||September 11, 2014|
|First Name:||Shyuan-Ren (Clayton)|
|Office:||Office of Safety Research and Development|
|Team:||Safety Data and Analysis Team [HRDS-20]|
|Program:||Turner-Fairbank Highway Research Center|
|Roadmap/Focus area(s):||Comprehensive Approach to Safety|
|Project Description:||The Interactive Highway Safety Design Model (IHSDM) is a suite of software analysis tools for explicit, quantitative evaluation of safety and operational effects of geometric design decisions during the highway design process. The complete IHSDM suite consists of six modules: Policy Review, Crash Prediction, Design Consistency, Intersection Review, Traffic Analysis, and Driver/Vehicle.|
The objective of this project is to provide life-cycle systems engineering and software development services for the Interactive Highway Safety Design Model (IHSDM) software system, including:
(1) Maintain the current public release of IHSDM.
(2) Provide system engineering and software development services to incorporate enhanced and new capabilities.
(3) Provide services and support to IHSDM developers, testers, users, external application developers, and distributors.
|Background Information:||The Interactive Highway Safety Design Model research has been underway for more than 15 years, and software development for more than 10 years. A major milestone was reached in January 2003 when the 2003 public release of IHSDM for two-lane rural highways was first made available. During the past few years, the Federal Highway Administration has continued to make improvements in the user interface and enhancements of software functionalities.|
|Product Type:||Promotional materials|
|Test Methodology:||Internal and external software testing|
|Other Information:||The 2010 Interactive Highway Safety Design Model Release focuses on the following major enhancements and additions: the Crash Prediction Module, intended to be a faithful software implementation of Part C (Predictive Method) of the American Association of State Highway and Transportation Officials' Highway Safety Manual, which provides crash prediction methodologies for two-lane rural highways, multilane rural highways, and urban/suburban arterials; an expanded Design Consistency Module, which now accommodates both low- and high-speed facilities; and enhances reporting capabilities.|
|Expected Benefits:||The Interactive Highway Safety Design Model evaluates existing and proposed alternative highway geometric designs, and provides estimates of their expected safety and operational performance. This safety evaluation tool helps project planners, designers, and reviewers justify and defend geometric design decisions.|
|Deliverables:||Name: 2010 Interactive Highway Safety Design Model Public Software Release and Subsequent Annual Updates|
Product Type(s): Software, Promotional materials, Training materials
Description: The Crash Prediction Module (CPM) of the Interactive Highway Safety Design Model software suite is a faithful implementation of the American Association of State Highway and Transportation Officials' Highway Safety Manual.
