More than a Progressive Safe System
Product Overview
In-cab alert
As a VRU is detected within the danger zones an in-cab alert emits both visual and audio alerts. Alerts in line with the TfL Progressive Safe System technical requirements. Can accommodate additional side and rear cameras to upgrade system for 360 VRU Detection.
Monitor
Mounted in cab the monitor provides visual alerts of VRU detection within the designated zones. Monitor auto-switches or split screens between nearside (BSIS) and (MOIS) detection zones. Rather than purely audio and ‘traffic light’ style visual alerts the in-cab monitor displays camera footage to remove any doubt on what has been detected
AI Controller
Affixed in-cab (protecting it from accident damage) the AI controller powers 2 x wide angle HD 1080 cameras (BSIS/MOIS) but can support up to 4 cameras for 360 protection above PSS requirements. The unit contains built in SD Card storage constantly recording and acting as a mini MDVR. With GPS, Wi-Fi, 4G support and proprietary app for calibration and set-up, live view and remote functionality are also possible.
Wide Angle 1080 Cameras
High-resolution wide-angle camera are positioned on the vehicle with their coverage zones meshed together to cover the TfL PSS zone requirements. Exact locations will differ from vehicle type and body build but one camera will be mounted nearside (BSIS) and one mounted front of the vehicle (MOIS). The system uses wide angle HD cameras with the AI processing carried out at the head unit rather than in the camera head. This keeps the cost of any camera replacements to a minimum and enables to use of unobtrusive, low-profile cameras matching the appearance of other that maybe already installed on a vehicle.
External Speaker
Sounds audible warning of the vehicles intention to make a left hand turn.

Progressive Safe System FAQ
- Has there been any change to the DVS 2024 enforcement date?
In it’s inception DVS 2024 was to be enforced from 28th October 2024, with a grace period to allow operators time to fit a PSS until January 2025.
This grace period was to be made available to operators – ON APPLICATION – and was not automatic. Applications for the grace period required operators to make a specific application via their London Road User Charging account supplying:
Evidence that you have installation works arranged to fit the Progressive Safe System but that this is scheduled for after 28 October 2024
Seperate applications will need to be made for EACH VEHICLE operators wish to receive a grace period for.
As of July 2024 the length of this grace period has been extended to 4th May 2025. An extension of the grace period by 3 months. The same conditions regarding APPLICATION for this extension apply.
- Sensors v radar v AI cameras?
The debate over the capabilities of both will continue to rage. Whilst it seems agreed that ultrasonic sensors are not intelligent enough to fulfil the requirements, radar or microwave sensors may determine the difference between a pedestrian and street furniture. Detecting a VRU approaching a stationary vehicle represents a different challenge, and the ability of a sensor to pick-up a protective clothed and helmeted motorcyclist or hooded pedestrian is debateable. ACSS supply a tested AI camera solution. Cameras which run video scene analysis on the blind spot area and pick out the human frame (shoulders, head, neck) offer the best method of detection by alerting the driver and displaying the view on an in-cab monitor. Cameras may get dirty and need cleaning yes, but there’s no arguing with what you can see with your own eyes on a screen!
- But the TfL specifications mention sensors, not AI cameras?
TfL’s Guidance For Operators and technical Specifications on BSIS & MOIS do make reference to ‘sensor systems’, but equally reference ‘can be achieved in the way that works best for the technology supplier & the vehicle operator’ and ‘sensors or other means of technology’. Cameras are the best sensor technology there is. They offer detection and full view. There is no reason to think that a AI camera solution will not be compliant with the TfL requirements.
- When will, and what will, the next DVS changes be?
At the inception of the Direct Vision Standard the scheme was scheduled to be reviewed in 2024. This has now occurred with the systems and technology updated. DVS Phase 2 is due to be reviewed in 2030. Nobody know whats will happen then but it would seem with the CCTV industry moving towards AI, more of this technology will be factored in.
- Are TfL approving and ‘rubber stamping’ PSS solutions?
TfL are not pre-approving Progressive Safe System solutions. A solution from a reputable supplier and a system offering UNECE Regulation 151 & 159 approval are the safest bet. The TfL technical specifications on BSIS & MOIS state ‘vehicles that are approved to UNECE Regulation 159 / 151 will be deemed to comply with all of these requirements’.
- Which PSS System should I fit to my fleet?
Technical specifications and timelines have been published by TfL since the summer of 2023. Whilst the specifications are detailed, they are not 100% clear and in places could be viewed as contradictory. This ambiguity/lack of clarity and scope of the changes has led to suppliers offering different PSS solutions. Sadly, it has also meant a lot of ‘new arrivals’ to market offering discount solutions. It would seem wise to be wary of new operators and evaluate all solutions based on merit and likelihood of fulfilling the TfL requirements rather than purely price. Long established and accredited suppliers with long standing relationships with manufacturers will bring you the compliant solutions. ACSS have designed a system not only to fulfil the TfL requirements but to exceed and offer the highest level of protection and safety for vulnerable road users (VRU) and HGV drivers.
