For detailed information on how projects, highways, intersections, Site Sets and evaluations are related, refer to the "IHSDM Interface and Data Organization" section of the IHSDM documentation (access via Help > Help Browser from the IHSDM main menu).

The Tutorial folder of the IHSDM software contains over 20 sample archived Projects. These Projects are referenced in various Tutorial exercises, but can also be used apart from the Tutorial for users to become familiar with aspects of IHSDM Projects. Sample Projects include:

• IHSDM Pike: three projects related to the 2.7 mile long IHSDM Pike are available – one with IHSDM Pike as a rural 2-lane highway (IHSDM Pike Project), one as a rural multilane highway (IHSDM Pike-Rural Multilane), and one as an urban arterial (IHSDM Pike-Urban Arterial).
• Example Project 1 – Tutorial Lesson 9: a version of IHSDM Pike used in Tutorial Lesson 9 on Output / Reporting.
• Example Freeway: An "Example Freeway" highway network that contains a 6-lane freeway segment with 2 crossroads and 2 interchanges, including C-D roads, ramps and ramp terminals.
• Example Freeway-Economic Analysis: A version of the "Example Freeway" project (see above), containing an existing highway network and two alternative cases. IHSDM Tutorial Lesson 11 (Economic Analyses Tool) uses this project as a case study.
• HSM Chapter 18 Sample Problems: 5 Projects related to HSM Chapter 18 Sample Problems (SP) 1-5 for Freeway Segments (HSM Ch 18 SP1, HSM Ch 18 SP2, HSM Ch 18 SP3, HSM Ch 18 SP4, and HSM Ch 18 SP5).
• HSM Chapter 19 Sample Problems: 6 Projects related to HSM Chapter 19 Sample Problems (SP) 1-6 for Freeway Ramps/Interchanges (HSM Ch19 SP1, HSM Ch 19 – Sample Problem 2, Entrance Ramp - HSM Ch 19 SP3, Ramp Terminals-Ch19 SP4, A4 Ramp Terminal 1-Way_Stop HSM Ch 19 SP5, and B2 Ramp Terminal AWSC_HSM Ch 19 SP6).
• Siteset-Rural Multilane: a sample Site Set, containing data for Four-Lane Undivided Segments, Four-Lane Divided Segments, Three-Legged Minor-Road Stop Control Intersections, Four-Legged Minor-Road Stop Control Intersections, and Four-Legged Signalized Intersections. This Site Set is used in Tutorial Lesson 4 (Crash Prediction Module).
• Pennsylvania I-70 Case Study: three projects related to an interchange alternatives analysis case study, including projects for the two alternatives evaluated (Alternatives 2A and 3), and a "training" version of the Alternative 2A project. These projects are used in Tutorial Lesson 4, Exercise 4.9.
• Roundabout Exercises: two projects are used in Tutorial exercises related to the roundabout crash prediction method.
• IHSDM Urban Network: three projects, which contain data for an urban arterial (major road), 4 minor roads, and their intersections (including a roundabout); used in Tutorial Lesson 4 (Crash Prediction Module), Exercises 4.12 and 4.13, and Lesson 10 (Crash Prediction Module Calibration), Exercise 10.11.
• IHSDM Freeway Example - Original Data and IHSDM Freeway Example - Reversed Data – contain data for a freeway section with two interchanges; used in Tutorial Lesson 12 (Data Considerations), Work Problem 2.
• An IHSDM Economic Analyses project (Example Freeway), related to Tutorial Lesson 11 (IHSDM Economic Analyses Tool (EA Tool) Tutorial).
