IHSDM - HSM Predictive Method 2012 Release is available

Postby mdimaiuta » Tue Oct 02, 2012 9:53 am

The 2012 Public Release of Interactive Highway Safety Design Model (IHSDM – version 8.0.0) is now available for free downloading at http://www.ihsdm.org. Please be advised that this 2012 Public Release contains major enhancements focusing on 1) a Beta version of crash prediction capabilities for mainline freeways segments based on draft Highway Safety Manual (HSM) materials developed under NCHRP Project 17-45; 2) a new site-based data input and analysis capability that provides users with more flexibility in how data are entered; and 3) improvements to Help/Documentation and the IHSDM System Administration Tool.

The IHSDM is a suite of software analysis tools for evaluating safety and operational effects of geometric design decisions. This 2012 Public Release includes six evaluation modules, namely – Crash Prediction, Policy Review, Design Consistency, Intersection Review, Traffic Analysis and Driver/Vehicle Modules. The 2012 version of the Crash Prediction Module (CPM) serves as a faithful implementation for the 1st edition of AASHTO’s HSM’s Part C – Predictive Methods for two-lane rural highways (HSM - Chapter 10), multi-lane rural highways (HSM - Chapter 11), urban and sub-urban arterials (HSM - Chapter 12), and proposed draft chapter for freeways. In addition, software development efforts to support a proposed draft chapter for ramps/interchanges will begin shortly. The other IHSDM evaluation modules are applicable to rural two-lane highways. For more information on the Highway Safety Manual, please go to: http://www.highwaysafetymanual.org.

Please note that a Calibration Utility was developed and added to the IHSDM Administration Tool (Admin Tool) in 2011, with step-by-step instructions and hands-on exercises illustrated in a Tutorial lesson for 2-lane rural highways, multi-lane rural highways, and urban and sub-urban arterials. This Calibration Utility was intended to assist agencies in implementing the calibration procedures described in the Appendix to HSM Part C. We also plan to provide similar functionality for freeways in future updates.

For existing registered IHSDM users, please use your IHSDM username and previously assigned password to access and download this new release. If you already have an earlier version of IHSDM installed in your system, a call home feature / message will also remind you to update it to the latest version next time you use the software. For new users, please look for “download registration” at http://www.ihsdm.org. On this website, you can also find additional information related to case studies / user applications, past webinar materials, and frequently asked questions.

A web conference to introduce the IHSDM 2012 Release will be held on Tuesday, October 16, 2012 between 1:00 pm (EST) and 2:30 pm (EST); the web conference is open to all individuals and/or organizations. The meeting URL, teleconferencing number and additional instructions will be sent to you after registration. Please register by October 15 (Registration URL: https://www.nhi.fhwa.dot.gov/resources/webconference/web_conf_learner_reg.aspx?webconfid=25033).
