Light rail and trams
For more than ten years, we have been developing driver assistance systems designed specifically for tram operation. These are based on tried-and-tested automotive technology from Bosch and help to reduce the risk of accidents. Our systems make complete surround sensing and perception for your tram fleet a reality.
Tram forward assist
Our camera systems and radar sensors of the latest generation monitor the area in front of the tram, detect other traffic participants, and warn against potential accident risks.
Accidents involving trams result in high repair costs, reduce the availability of the fleet, and disrupt the tram schedule. Our tram assist suite minimizes the risk of accidents and disruptions in a targeted manner, thereby increasing the availability of your fleet.
Our modular assistance system tram forward assist is available in three configuration levels:
- Tram forward assist with camera system and radar sensors of the latest generation
- Tram forward assist plus featuring the standard forward assist technology with the addition of LiDAR sensors
- Tram forward assist extended range with radar systems at both ends of the vehicle to reduce the risk of rear-end collisions for your trams when traveling at higher speeds and in tight bends

Tram near range assist
Our ultrasound-based assistance system detects obstacles and dangerous situations in the near range of your tram vehicles.
Accidents involving trams result in high repair costs, reduce the availability of vehicles, and disrupt the tram schedule. Our tram assist suite minimizes the risk of accidents and disruptions in a targeted manner, thereby increasing the availability of your fleet.
The tram near range assist system uses ultrasonic sensors to monitor the near range of your tram vehicles – in all directions if required. The system detects persons located, for example, directly in front of a tram car or between two coupled trams.

Tram flank assist
Our radar-based system detects vehicles to the side of your tram power cars. It also enhances the surround sensing function in combination with the tram forward assist system.
Accidents involving trams result in high repair costs, reduce the availability of vehicles, and disrupt the tram schedule. Our tram assist suite minimizes the risk of accidents and disruptions in a targeted manner, thereby increasing the availability of your fleet.
Particularly in inner-city traffic, trams are required to share public traffic areas with other vehicles. When these vehicles enter the area of the tracks, for example, when cornering or turning, this increases the risk of accidents. The tram flank assist system reduces this accident risk by using radar sensors to monitor blind spots that are difficult to see by the tram drivers.

It provides a clearer view where other vehicles move close to the track area.
- Detection of vehicles in blind spots beside the tram car
- Warning of any vehicles that may enter the track area
- Enhanced safety, fewer driver-related accidents
- Increased comfort and greater relief for driving personnel
- Fewer delays and breakdowns
- Fewer repairs, lower repair costs
Tram focus assist
Our system with an infrared camera monitors the driver’s cab and detects whether or not the tram driver is focusing on their tasks.
Accidents involving trams result in high repair costs, reduce the availability of vehicles, and disrupt the tram schedule. Our tram assist suite minimizes the risk of accidents and disruptions in a targeted manner, thereby increasing the availability of your fleet.
Human error remains one of the main causes of traffic accidents, and this also applies to tram drivers. Our tram focus assist system uses a near-range camera system to monitor the upper body and facial expressions of the driver. It checks whether the person in the driver’s seat is focused on their task and issues a warning if it detects any distraction, tiredness, or microsleep. It also intervenes in the tram operation if the driver should leave their workplace, for example, due to a medical emergency.
