The paper proposes a control system with the brake and the steering for developing a driver assistance system. The purpose is to design a cruise control method to track the road geometry with a predefined velocity and guarantee the road stability of the vehicle simultaneously. An actuator selection method is developed in the control design, in which the actuator limits, energy requirements and ...

In automotive design, safety remains a growing priority. Recently focus has extended beyond the occupants of the vehicle and turned towards other Vulnerable Road Users (VRU). Simple night vision systems have already become an important safety feature in modern high end automobiles. The next generation of advanced driver assistance systems will automate the detection of VRUs, to improve safety f...

1 Due to the availability of GPS sensors in a variety of everyday devices, GPS trace-data is becoming 2 increasingly abundant. One potential use of this wealth of data is to infer, and update, the geometry 3 and connectivity of road maps, using what are known as “map generation” or “map inference” 4 algorithms. These algorithms offer a tremendous advantage when no existing road map data is 5 pr...

We propose a new approach for vision based longitudinal and lateral vehicle control. The novel feature of this approach is the use of binocular vision. We integrate two modules consisting of a new, domain-speciic, eecient binocular stereo algorithm, and a lane marker detection algorithm, and show that the integration results in a improved performance for each of the modules. Longitudinal contro...

In the present study, an integrated framework for automatic detection, segmentation, and measurement of road surface cracks is proposed. First, images are captured, crack regions detected based on fifth version You Only Look Once (YOLOv5) algorithm; then, a modified Residual Unity Networking (Res-UNet) algorithm proposed accurate segmentation at pixel level within regions; finally, novel featur...

We present an Unmanned Aviation Vehicle-based Photogrammetric mapping system in this paper. This work is part of a project monitoring of unpaved road condition using remote sensing and other technology, sponsored by the US Department of Transportation. The system is based on a low cost model helicopter equipped with a GPS/IMU and a geomagnetic sensor to detect the position, attitude and velocit...

Road traffic information is the basis of road traffic management and control. Due to the special design of the sensor coil and ferromagnetic core, traffic survey system which uses micro ferromagnetic inductive coil vehicle detector, not only has the features of small size, simple installation and little road surface damage, but also has the advantages of output signal strength, simple signal pr...

Construction, development and maintenance of the road network are central activities for several public authorities. In cooperation with the Norwegian road authorities, we have developed an approach for automated vehicle detection and generation of traffic statistics from QuickBird images. Satellite surveillance serves several obvious advantages over the methods that are being used today, which...
