in front wheels driven vehicles, fuel economy can be obtained by summing torques applied to rear wheels. on the other hand, unequal torques applied to rear wheels provides enhanced safety. in this paper, a model with seven degrees of freedom is considered for the vehicle body. thereafter, power-train subsystems are modeled. considering an electrical machine on each rear wheel, a fuzzy controlle...

This paper presents an automatic method for road network extraction from low-resolution images using hierarchical grouping. The method consists of three major steps: firstly it extracts lines from original images and generates smooth lines in a split-and-merge operation; a hierarchy of line images is generated using different thresholds for line length, based on the extracted line images; the l...

This paper presents an automatic method for road network extraction from low-resolution images using hierarchical grouping technique. The method consists of three major steps: firstly it extracts line features from original images and generates smooth lines in a split-and-merge operation; a hierarchy of line images is created using different thresholds for line length, based on the generated li...

In order to improve the accuracy and real-time of structured road recognition algorithm, this paper puts forward a recognition algorithm of the structural road based on piecewise linear model. Firstly the original image was the initial region of interest division and pretreatment, using an improved Otsu algorithm and mathematical morphology processing image segmentation, eliminate noise and spl...

In this paper, a new access method is proposed for current positions of moving objects on road networks in order to efficiently update their positions. In the existing index structures, the connectivity ofedges is lost because the intersection points in which three or more edges are split. The proposed index structure preserves the network connectivity, which uses intersection oriented network ...

The presented study compares three alternative straight-line approximations of the longitudinal road-profile power spectral density (PSD). The one straight line and two and three split straight-line approximations were analyzed. The minimizing of the root-meansquared error (RMSE) was used as criteria of goodness of fit for the approximation models. The statistics of the PSD approximation model ...

Abstract—this paper develops a real-time traffic signal timing model which is to be integrated into a single intersection for urban road, thereby solving the problem of traffic congestion. We analyze the current situation of the traffic flow with release matrix firstly, and then put forward the basic models to minimize total delay time of vehicles at the intersection. The optimal real-time sign...

OBJECTIVE To understand the critical factors that are likely to influence road traffic fatality rates in large cities around the world in the next few decades. MATERIAL AND METHODS Road traffic fatality data for 56 cities around the world and for cities with a population of greater than 100,000 in the USA were collected and analysed to understand factors affecting differences in fatality rate...
