The device (V-Guard) detects a cyclist riding a path, determines its speed and signals its approach to the intersection with the road. Thus, the drivers are not surprised by the suddenly emerging cyclists (our observations show that there are several dozen places in Wroclaw itself, where visibility at this type of intersection is severely limited by buildings, hedges or trees). In addition, V-Guard has the functionality to count cyclists crossing a given route. This type of data is very valuable for officials planning to develop a cycle path system.

General characteristics of the device: The main task of the device is to detect a cyclist approaching the crossroads of a bicycle and car road and display a message warning drivers.
