Construction sites and autonomous vehicles

Together with partners from science, the construction and automotive industries, we are developing a system that shows autonomous vehicles the way through construction sites or inadequately marked roads. A reliable identification and evaluation of obstacles and safe navigation through these routes play an important role.

Autonomous driving through construction sites is a major challenge for designers and engineers of such systems. Construction sites often show complex situations such as narrowed lanes or short-term changes during the course of construction. Even tight curve radii or the detour to the opposite lane are to be mastered in the course of the construction site. These states are not normalized traffic situations and thus difficult to detect via the sensors installed in vehicles - especially in bad weather conditions.

Poor detection of construction site situations

Narrowed lanes, short-term changing routes during the course of construction are not standardized traffic situations. Even tight curve radii or the detour to the opposite lane are very difficult or impossible to detect via the sensors installed in autonomous vehicles.

Lack of security within the construction sites

Complex situations, such as construction sites or inadequately marked infrastructure, require an increased level of appropriate security measures. Compliance with these measures is the basic requirement for the protection of construction site personnel and road users. This is the only way to minimize the risk of accidents and traffic jams.

Missing information on construction sites

Construction sites usually lack a wealth of basic information. These are, for example, the exact location, the start of the construction site and the end, and the nature and extent of the construction project. This causes traffic jams and accidents. Not only does it harm the environment, it even risks human lives!

Solution for different stakeholders

Construction industry

Due to the integrated sensors in the traffic guidance devices, a warning light (beacon), which is in the wrong position, can be recognized immediately. A possible accident due to confusion or a beacon on the road can thus be avoided and more safety can be ensured on the construction site.

Traffic safety

Legally, a construction site must be physically inspected every 6 hours. This process takes time and money, which can be saved by our digital surveillance. At the same time, abnormalities are recorded and declining batteries are detected in appropriate time.

Traffic guidance and management

If there is more qualitative real-time information on where and for how long a construction site exists, the flow of traffic can be better controlled by optimizing planning for future construction sites.

Other industries

Autonomous vehicles conquer their ways also off the regular traffic routes. The demand for guided trails in earthworks, with its miles of transportation routes, rises. Another need exists in mining operations, both open pit and underground mining.

Innovative sensors from INTEFRA

Robust, simple and safe

The sensors are robust and equipped for rough construction site use. The simple installation and commissioning of the system is no more complicated than setting up the traffic control system itself. Together, this leads to a secure overall system.

Intelligent overall system

After the initial setup of the overall system, the sensors remain in an energy-saving mode, they “sleep”. Only when changes occure, the sensors react. This can be the switching of beacons by the construction site personnel or the repelling by passing traffic. Intelligent algorithms ensure that constantly updated traffic information is made available.

Real-time state of the track

With each change in position of a traffic control device, the new course of the route is calculated in fractions of a second. This can also lead to the track being blocked in the detection of an accident, for example, when a beacon with excessively high acceleration values ​​is thrown off.

Centimeter exact position of the track

Mathematical models provide a centimeter-accurate image of the topography of road construction sites or insufficiently marked roads. From this, traffic routing is derived, one or more lanes. This digital twin of the routes can be integrated via interfaces into traffic control systems or operational dispatch control stations.
