Hostile Vehicle - Swept Path Analysis

Using AutoCAD to plot the swept path of hostile vehicles can assist in the correct design and effectiveness of vehicle barrier systems.

The above image is a simple AutoCAD drawing of the swept path a lorry would take in attacking a crowded place. The red lines show the actual tracing of the wheels and the green lines show the path of the outer body of the vehicle. The blue circles show the point where significant change in direction is required.
The software we use has a wide range of sample vehicles from small cars to lorries and the swept path and approach speed will be very different for each type. The AutoCAD software can simulate different rates of acceleration and other parameters that are required for the correct design of mitigation measures such as the below design principles;

1. Slow the attacking vehicle by managing approach speed and passage.
2. Stop the attacking vehicle by using the correct vehicle barrier systems.
3. Maintain suitable standoff distances from buildings by considering the final resting place of the vehicle and how far debris can be permitted to penetrate the barrier.

Click here to see a simple video of swept path tracking from an AutoCAD application that provides valuable data such as limits to turn radii and acceleration capabilities of different vehicles and this in turn assists with the design criteria for hostile vehicle mitigation.

This video is the plain top view but we can also provide 3D views from any angle or height to gain more insight into the swept path.
