During the conceptual design and development of the ZalaZONE Smart City traffic light control system, the aim of the road traffic light control system is to be able to control the highlights of fixed pre-installed road signal heads (vehicle, bicycle, pedestrian and auxiliary signals) separately during the vehicle tests. All light signaling devices at the 6 traffic light-controlled intersections designated in the ZalaZone Smart City zone must be accessible from a central room using central control software running on a central computer. This requires designing the basic concept of the system, from both the hardware and software demand side. Another task is to produce a digital twin model of the system.
Environmental perception research will test and further develop previously developed camera and LiDAR fusion-based object detection algorithms, with a special focus on fusion solutions based on the extension of LiDAR data with image features. We examine the effect of each image feature and each region of the point cloud on the functioning of the neural network. The tests are performed on real data. We also focus on the design and construction of sensor stations for raw data collection, equipped with camera, LiDAR and Radar sensors. We perform measurements on the ZalaZone test track, where we test the measurement range of each sensor (various LiDAR sensors, camera and radar of an infrastructure) and the detectability of different types of objects (pedestrian, vehicle). In the topic of HD map update, we focus on the development of prototype software that integrates standard map and communication formats.
In the field of modeling and simulation, the goal is to test distributed control with a virtual implementation of wireless communication (VEINS simulation system).
The electronic developments of the moving platform include the construction of individual, high-capacity batteries, the design of high-performance DC electric motors, the unique remote control of the platform, which allows the device to be positioned or remotely returned to the desired position at low speed. The design of the undercarriages also required important development solutions, as the widest possible wheelbase had to be achieved for the desired stability, with the best braking effect in addition to the limited braking force. In terms of drive, optimizing chain drive is the development task. Accordingly, ideal steering must be resolved.
To select the material of the dummy, we are looking for a sponge material with the right hardness, good energy absorption, good resistance to dynamic forces and the requirements of radar reflection.
