The COPS@Zebra (Collision Preventing Safety System) system is an innovative system consisting of four signs, where two signs are intended to warn drivers of approaching pedestrian crossings, and two signs to warn pedestrians of approaching vehicles.
An additional long-term effect of the COPS@zebra system is traffic calming, as the fact that pedestrians and other passing road users see the current speed of road traffic or individual vehicles further motivates the responsible driver to adjust the speed.
The PHP module is a speed display that is oriented to be visible to a pedestrian who is about to cross a crosswalk. The data on the vehicle speed of the PHP display is received from the TFL modules via a radio connection. In case of vehicles approaching from both directions, the PHP displays show the speed of the faster vehicle.
The speed display also has an effect on traffic calming, as the fact that pedestrians and other passing road users can see the current speed of road traffic or individual vehicles further motivates the responsible driver to adjust the speed.
The basic structure and an example of the layout of the units of the COPS@zebra system are shown in the figure below

Sistem zajema tudi dodatne podatke za namen prometne statistike in sicer sledeče:
• gostota prometa (število vozil na uro)
• hitrosti vozil (najvišja, povprečna, povprečna 85%, število prekoračitev hitrosti)
• znižanje hitrosti vozil po vklopu opozorilnih signalov (viden neposreden učinek na umirjanje prometa)
• ter druge prometne in sistemske podatke za nadzor pravilnosti delovanja.
