Vehicle CCTV specialist Exeros Technologies has developed a product to help with cyclist safety.
Its camera uses computer algorithms to distinguish vulnerable road users (VRUs) and cyclists from anything else it sees on the roads. Road markings, road furniture and other inanimate objects are removed from detection.
According to the company, the system has proved more than 99% accurate in tests of 5,000 samples piloted with Go-Ahead Buses and in central London.
It is designed to help alleviate the problem of false alarms. As the camera is an independently ‘active’ system, it works without the need to have any technology placed on VRUs or bicycles. It also overcomes the issue of ‘shadowing’ that may be caused by radar-based systems – radar will not penetrate the sides of a van, for example, creating a ‘shadow’ towards the rear of adjacent vehicles, where a VRU could be.
The Exeros camera system acts as the visual recorder while a software algorithm scans the imagery and deciphers which images contain high-risk objects. When the camera detects VRUs in the blind spot, it alerts the driver by displaying the risk on a screen and highlighting VRUs in a colour that varies depending on risk level.
The cameras have built-in speakers which sound a caution to VRUs if one is detected in the HGV blind spot when the vehicle is about to make a turn. The system can detect the angle of approach of a cyclist or VRU and can warn against a potential collision.
The cameras can be retrofitted to any HGV.
