Hostile Vehicle Mitigation (HVM) is an essential component of a comprehensive counterterrorism (CT) strategy, not just a standalone item in a traffic management plan. It’s important to understand HVM as part of a broader security effort aimed at protecting public spaces from terrorist attacks.
“HVM is not just about physical barriers but is a multi-faceted approach involving technology, design, and strategic planning to protect against vehicular attacks.”
To effectively integrate HVM into a CT strategy, a holistic approach is needed. This approach should consider not only physical barriers but also the procedural elements of security. Continuous assessment and adaptation to evolving threats are essential, as are training and preparedness for all involved. By taking such a comprehensive approach to security, communities can improve their resilience against terrorist threats and make public spaces safer for everyone.
Effective Hostile Vehicle Mitigation (HVM) doesn’t necessarily require spending vast sums of money; at its core, it’s all about meticulous planning. The key to enhancing security and resilience against terrorist threats in public spaces lies in strategic, well-thought-out approaches that prioritise understanding the specific vulnerabilities and needs of each location.
By focusing on the intelligent placement of physical barriers, optimising the layout of public spaces to naturally deter hostile vehicles, and integrating these measures with existing infrastructure, organisations can achieve robust security outcomes without excessive expenditure. Collaborating with PSSA members can also provide valuable insights and resources, helping to ensure that planning efforts are grounded in best practices and the latest research. The most effective defence against threats is a well-planned strategy that considers the unique aspects of each space, coupled with a commitment to continuous improvement and adaptation to new challenges.
HVM provides critical time for trained personnel, including stewards, operators, and emergency services, to respond to threats. This response time is crucial for initiating emergency procedures, such as evacuations and lockdowns, which can save lives in the event of an attack.
However, it’s important to recognise that terrorists may adapt their methods if confronted with physical barriers like HVM. For example, an attacker might abandon a vehicle blocked by HVM barriers and resort to other forms of violence, such as knife attacks.
The concept of ‘standoff’ distance is vital in the context of HVM. This refers to the physical space between potential threats and the areas you’re trying to protect. Increasing this distance can provide more time for emergency responses and the implementation of security procedures and response from trained operatives who’ve been told what to do in the event of an attack, helping to reduce the consequences of an attack. Sufficient separation from the area being safeguarded allows for activating air horns, instructing individuals to “run, hide, tell,” allowing for the timely arrival of emergency responders, and ensuring that communication, lockdown, invacuation, and evacuation procedures can be effectively implemented. These actions collectively help to minimise harm and, most importantly, save lives.
