Threat Vehicle Vector Analysis. What is it and how does it work?

This crucial information forms the basis for an effective security design and is obtained by calculating the maximum impact energy possible at those locations.

Threat Vehicle Vector Analysis

Threat Vehicle Vector Analysis is just one of the design services that Sloan offers. Due to its specialized nature, we offer this explanation to help clients understand the role it plays in security design, and, most importantly, its ability to reduce project costs.


In short, vector analysis determines the minimum crash rating required at each location on the project’s perimeter. This crucial information forms the basis for an effective security design and is obtained by calculating the maximum impact energy possible at those locations.


For example, suppose roadway geometry and vehicle dynamics at one site show that a 45 mph perpendicular impact is possible. This high kinetic energy impact requires a very well thought out design. Whereas a 20 mph, the angled impact would impart less energy and require lower crash ratings resulting in lower costs.

If vector analysis is so important what information is required to begin?

  1. What is the threat vehicle (e.g. car, SUV, heavy goods truck)?

  2. What areas or assets need to be protected (e.g. front entrances, gathering areas, critical infrastructure, iconic locations, etc.)? This determines where the crash-rated perimeter will be located.

  3. What type of threat is to be mitigated; accidental impact or intentional attack?

  4. What are the possible routes of the threat vehicle? This may require a vehicle path analysis, which is another service that Sloan offers.

Based on these parameters a thorough vector analysis will determine the minimum crash rating required at all points on the perimeter. This crash rating can then be used to choose the right solution for each point ensuring that security solutions are not over-designed nor under-designed.


Crash Rating Testing

Using this approach based on foundational information and proven methodologies produces a security design that is both effective and efficient. The Sloan team of security designers works together to ensure that no possible threat vector is missed or miss-calculated taking into account wrong-way approaches, multiple approach strategies including (insider threat, and deceptive approaches) to provide a very complete analysis you can rely on.
