Interactive Highway Safety Design Model Crash Prediction Tools: Applications in the Project Development Process

Wednesday, December 5, 2018

9 a.m. to Noon

This workshop will focus on use of the IHSDM Crash Prediction Module (CPM) to perform safety analyses at various phases in the project development process by applying Highway Safety Manual (HSM) Part C crash predictive methods. 

IHSDM (www.ihsdm.org) supports the Data-Driven Safety Analysis (DDSA) initiative that is part of the Federal Highway Administration’s (FHWA's) Every Day Counts efforts. IHSDM implements HSM Part C methods for a variety of facility types, including rural 2-lane and multilane highways, urban arterials, and freeway segments and interchange components.

This safety analysis tool helps users identify areas of safety concern within a given facility, and IHSDM outputs assist agencies in determining how to best invest limited resources to improve safety performance. IHSDM results help project developers identify and justify safety-related design decisions, and support decision making in the highway design process. Intended users include highway project managers, designers, and traffic and safety reviewers in State and local highway agencies and in engineering consulting firms.

Several case studies will be presented during the workshop to illustrate real-world IHSDM applications. These case studies will highlight a range of applications, such as:

  • Alternatives analysis (e.g., interchange configuration alternatives for a freeway project in Western Pennsylvania)
  • Safety impacts of design exceptions 
  • Economic analyses: using the IHSDM Economic Analyses Tool to assess the safety benefits of design alternatives compared to a base case
