Opis:: This paper presents a deep learning-based road recognition strategy for advanced suspension systems. A four-quarter suspension model with a magnetorheological (MR) damper is developed, and four typical road images with corresponding roughness data are collected. A back-propagation neural network based autoencoder and Convolutional Neural Networks (CNN) are utilized to form the deep learning structure. By utilizing the multi-object genetic algorithm, the optimal parameters can be obtained, and the control current can be adaptively adjusted. Simulation results indicate that the designed structure can identify the road type accurately, and the recognition-based control strategy can improve the suspension performance effectively.

Tytuł:: Visibility of an untypical obstacle in low beam headlights during driving at night

Tematy:: night driving

Opis:: The article deals with the problems connected with road traffic safety highlighting driver’s ability to notice an untypical obstacle in the light of low beam headlights while driving in the night. Visibility of an unlit object during the night is not only related to its motion but also to the necessity of its being lit to up to the required minimum height. On the basis of a study of a road accident, it was found that the standards accepted in reconstruction of the accident for determination of the light beam height to be used for lighting an obstacle should not be taken for granted. The driver’s surprise at the sight of an unlit obstacle is accompanied with the need to direct the light beam higher, which causes shortening of the distance available for a driver to react in an attempt to avoid hitting into an obstacle. An analysis of this case shows that verification of road accidents involving a crash with an untypical, incompatible obstacle that happen during the night needs to be carried out with attention and care. A simulation program V-SIM4 version and Ratschbacher AutoView database was used for calculation of the possibility to avoid an accident. The results obtained on the basis of the authors own investigations can also be used in information campaigns, education for road safety improvement and development of proper attitudes of the road traffic users.

Opis:: Cyclists are a vulnerable group of road users, especially when no separate infrastructure for cyclists is provided. Then, road factors such as distance and altitude differences can indirectly affect cyclists' safety. Therefore, the authors proposed a procedure based on the geometric characteristics of the road that can determine riding difficulties for cyclists. The proposed procedure can be used both by the public authorities who manage cyclists' safety and as a method of classifying the road network for cycling. The proposed procedure, based on the use of pattern recognition techniques, analyses data from a sample of nine riders who travelled on rural roads within the Municipality of Messina (Italy) to classify the roads according to their cycling difficulty. For each rider, duration, distance, road slope, altitude difference and spent calories have been measured and analysed. The collected data were used for the development of a model capable of predicting the cyclist’s physical effort as a function of the road alignment itself. Knowing the effort required to cycle along a route can contribute to a more complete assessment of road classification, commonly defined according to motor vehicles. Moreover, it may constitute a measure determining the safety of cycling by encouraging cyclists to travel along roads compatible with their physical abilities.

Opis:: The paper presents the analysis and discussion of video detection data usage for discrete transport systems safety improvement. The Autonomous Vehicles (AV) and the Augmented Reality (AR) research in connection with a Driving Assistance (DA) are presented. This article is going to show where the border between those two fields of interest is and how they are going to influence on the future of automotive. The proposal of the AR system – based on soft-computing methods used for an object classification problem – is given. The input data are taken from the real traffic monitoring system located at the set of roads in Poland. Data from the monitoring devices are used to analyze the travel time of vehicles – elements of the transportation system. The travel time model taking into account the real road situation is built. The proposed solution can be an essential tool for the owner and administrator of the transportation systems

Opis:: The paper proposes the image half-byte format applying to images from a road traffic data recorder. The format defines image pixel values using differences between a pixel value and a determined base value. The image half-byte representation can be further processed by appropriate methods. The paper presents also results of converting test images into the half-byte format.
W artykule zaproponowano półbajtowy format obrazów zastosowany do obrazów z rejestratora danych ruchowych. Format określa wartości pikseli korzystając z różnic między wartością piksela a ustaloną wartością bazowa. Półbajtowa reprezentacja obrazu może być dalej przetwarzana przy wykorzystaniu odpowiednich metod. Przedstawiono również wyniki konwersji obrazów testowych do formatu półbajtowego.
