McHenry Software, Inc. (MSI) was formed in 1994 with the explicit intent to create, distribute and support accident reconstruction and vehicle simulation software. The McHenry’s have 90 years. Virtual CRASH accident reconstruction software is used for accident reconstruction simulation analyses involving passenger vehicles, pedestrians, bicycles, motorcycles, commercial vehicles, and more. Virtual CRASH can be used for drawing scale diagrams, building 3D models, performing physics studies, creating animations, and more! Utilizes the latest technologies in the Field of Accident Reconstruction including Total Stations, Vulcan Spatial Lasers, 3D Scanning Lasers, CDR Crash Data Retrieval Systems. ABSTRACT: Accident reconstruction software Pc-crash was used in this paper to analyze and set characteristic parameters. Pc-crash was taken as the simulation platform to construct the multi-rigid-body model of people, two-wheel vehicle and four-wheel vehicle in the accident scene. Simulation of the cause, process.

CDR data can be used to compute pre and post impact speeds using Vector (EDR-Momentum) sending that data to 360 LM for further analysis. The 360 LM information can be sent directly to SMAC (Simulation) by clicking on a few buttons.

TheTime-Distance EDM module will use EDM or CDR speed information to analyze thedata and plot the deceleration curves for the vehicles unavailable in any otherprogram.

Three new modules have been added (see screen captures below):

360 LM Omni - 28 combinations of Speeds and Angles may be used as UNKNOWNS with Vector Triangulation Technology (VTT) in Linear Momentum for maximum flexibility. While other programs allow 6 combinations (Speeds Only), REC-TEC uses all 28 combinations (Angles and Speeds), making it the Ideal tool to use with EDR based reconstructions.
School Bus Stop - displays a School Bus Stop graphically and numerically including Perception-Reaction Time and Distance, Braking Time and Distance, Clearance Distance, and Crosswalk Distance if applicable. The assumed bus length is also shown.
Work Zone (MUTCD) - displays the various elements of the three basic types of Work Zones describing the elements and showing minimum recommended dimensions based on Speed and Width of Offset.
