Vehicle Dynamics Assessment (VDA)

A Vehicle Dynamics Assessment examines how a hostile vehicle could approach and interact with a site or protected asset.

​

We assess factors including:

• Potential vehicle approach routes

• Vehicle speeds and acceleration opportunities

• Vehicle types and likely threat vehicles

• Approach distances

• Road layouts and geometry

• Gradients and changes in direction

• Existing physical security measures

• Impact locations and angles

• Stand-off distances

• Vulnerabilities around protected assets
   

The assessment helps establish the vehicle dynamics and operational requirements that should inform an appropriate HVM strategy

​

Hostile Vehicle Mitigation (HVM)​​

​​HVM is about reducing the opportunity for a vehicle to reach a protected asset and mitigating the consequences if an attack occurs.

​

State2 Security can support clients in developing proportionate HVM strategies that consider:

​

Assess
Understand the threat, site vulnerabilities and potential vehicle attack scenarios.​

Define
Establish appropriate operational requirements for the HVM measures.​

Design
Develop proportionate protective measures that work with the site's operational and architectural requirements.​

Assure
Review the proposed solution and provide confidence that it addresses the identified risk.

Importantly, HVM should be integrated with the wider environment rather than treated as a standalone security installation. 

​

HVM Operational Requirements

Before selecting a barrier or other protective measure, it is important to understand what the measure actually needs to achieve.

​

State2 can develop or review HVM operational requirements considering:

• Threat vehicle

• Vehicle speed

• Impact angle

• Required stand-off

• Protected asset

• Existing site conditions

• Access and traffic management

• Emergency access

• Pedestrian movement

• Operational constraints

• Integration with the surrounding environment
   

This provides a clear basis for subsequent design and procurement.

​

HVM Assessment & Review

​Already have bollards, barriers or other vehicle security measures?

​

We can assess whether existing arrangements remain appropriate for the current threat and operating environment.​

​

Reviews can consider:

• Existing VSB arrangements

• Barrier positioning and coverage

• Gaps and vulnerabilities

• Vehicle approach routes

• Stand-off distances

• Access arrangements

• Traffic management

• Impact performance information

• Operational procedures

Changes to the site or surrounding environment

HVM for New Developments

Early consideration of hostile vehicle risk can make a significant difference to both security and cost.
​

We can support:

• New developments

• Major refurbishments

• Commercial estates

• Corporate campuses

• Publicly accessible locations

• Major events

• Residential and private estates

• Infrastructure

• Mixed-use developments

• The objective is to integrate protective security into the development without unnecessarily compromising usability, appearance or normal operations.
