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. 

The Time-Distance EDM module will use EDM or CDR speed information to analyze the data and plot the deceleration curves for the vehicles unavailable in any other program. 

Two new modules have been added for 2017 as part of a new Traffic Engineering section (see screen captures below):

  1. 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.

  2. 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.

 School Bus  Stop

Crush5 with Vector Integration computing the pre-impact and post-impact speeds of both vehicles

Crush 5 - Vehicle 1

Crush 5 - Vehicle 2

Crush Crush5 - Maximum Engagement

Crush 5 (1-click) data transfer to 360 Linear Momentum

360 Linear Momentum Graphics (Plane of Impact)

360 Linear Momentum (1 Click) transfer to SMAC Interface

V1 Centroid of Damage to V2 Centroid of Damage Impact

Optional: 360 Linear Momentum (1-click) data transfer to Vectors (EDR-Momentum) with Formulae displayed

Easy (1-click) transfer of both input and computed data from one module to another is a hallmark of REC-TEC Platinum.  It not only serves to verify the computations using completely different methodologies, it generates additional data resulting in a more comprehensive picture of the event in question.
