Replacing the previous parameters set by the Direct Vision Standard (DVS), the Progressive Safety System (PSS) enhances safety for Heavy Goods Vehicles (HGVs) operating within the Greater London area.
Recognising the unique challenges posed by large vehicles in urban environments, the PSS integrates cutting-edge technology and proactive measures to mitigate risks and improve road safety.
Reported road fatalities in collisions involving different types of vehicles in Great Britain, 2024
Clearly this figure is far too high and systems need to be put in place with the necessary technology able to work towards reducing these figures. Eliminating risk and reducing deaths to vulnerable road users (VRU) who have to co-exist around vehicles as it’s part of every day working life is Spillard’s objective. Using our 30 years of industry experience and internal R&D department, Spillard has designed the ideal solution to target this issue.
Distraction or impairment
If you are an HGV operator, before travelling through London, you MUST
apply for a vehicle permit. You will be granted a permit if the vehicle meets
the minimum DVS star rating. Those rated zero stars will need changes made
to their vehicle, making it safer by fitting it with Progressive Safe System
improvements.
At the core of the Progressive Safe System is Spillard's Human Detection System, controlled by two cameras – one covering the front of the vehicle and another covering the nearside. These cameras enable detection of pedestrians, cyclists, and other vulnerable road users in the vehicle’s vicinity. A visual image is provided on the monitor, with an audible alert which exclaims “person detected” through an internal speaker in the cab.
The Spillard Human Detection System identifies only human shape, human form and human characteristics.
This simple, yet clever system focuses on the most vulnerable on our roads, reducing distractions caused by more basic detection models that detect other objects like street furniture, roadside trees hedges.
Our Human Detection System aims to keep everyone safe and prevent injuries or worse.

sensors must be fitted to the front of a vehicle in order to prevent collisions at the frontal blind spot zone when a vehicle moves off from a stationary position. The AI Human Detection System from Spillard meets this standard, providing audio and visual displays when a vulnerable road user is detected.

will give drivers a wider field of vision and their cognitive workload will be reduced. Any CMS fitted on vehicles must eliminate any remaining blind spots, and will provide a visual alert of an approaching vulnerable road user, helping to prevent collisions in the blind spot area.

must provide comprehensive coverage along the passenger side of the vehicle to help drivers detect vulnerable road users. It is essential that they only activate when collisions are imminent, not in response to stationary vehicles or normal roadside objects.
that replaces mirrors, or a combination of both mirrors and camera systems, must be installed. This equipment must be fitted to the front and passenger side of vehicles to improve driver visibility.
must provide clear audible notifications when the vehicle is turning left or right (left for left-hand drive vehicles). This ensures that all vehicles can warn of an intended manoeuvre.
must be installed on the exterior of HGVs to communicate potential hazards to vulnerable road users nearby.
Spillard’s award-winning AI Human Detection System meets the criteria outlined by the Progressive Safe System, as it uses algorithms and deep learning technology to intelligently identify only the human form (vulnerable road users) through deep intelligent mapping.
This simple, yet clever system removes the chance of an annoying driving experience caused by more basic detection models that detect other objects like street furniture, dustbins and roadside hedges. This way, Spillard protects vulnerable road users, keeping them safe from harm as blind spots are eliminated as a result of expanding the driver’s field of vision.
