Accurate, detailed and up-to-date road information is of special importance in geo-spatial databases as it is used in a variety of applications such as vehicle navigation, traffic management and advanced driver assistance systems (ADAS). The commercial road maps utilized for road navigation or the geographical information system (GIS) today are based on linear road centrelines represented in ve...

In this work, we introduce an application of computer graphics to the validation of an automotive illumination system in dynamics conditions. We propose the creation of a virtual road, where it is possible to “drive” the vehicle for different kinds of tracks and to study the performance of the headlights in dynamics conditions on the road. The projection of the light is directly affected by the...

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...

In recent years the number of vehicles in roads have increased, which has causes high density in traffic and further problems like accident and road congestion. A solution regarding to this problem is vehicle-to-vehicle communication, where vehicles are able to communicate with their neighboring vehicles even in the absence of central base station to provide safe and more efficient road informa...

Road sign detection is important to a robotic vehicle that drives on roads automatically. In this paper, road signs are detected by means of rules that restrict and require signs to appear only in limited regions using wireless. They are then recognized using a PAN ID matching method. The method is fast and can easily be modified to include new classes of signs. As with any vehicle, an autonomo...

Light conditions are known to affect the number of vehicle accidents and fatalities but the relationship between light conditions and vehicle speed is not fully understood. This study examined whether vehicle speed on roads is higher in daylight and under road lighting than in darkness, and determined the combined effects of light conditions, posted speed limit and weather conditions on driving...

The project deals with counting the vehicle direction wise and also to alert the driver if there is any road block further ahead. The system is implemented using two IR sensors in each signal and main roads. When the vehicle is sensed using the first sensor the counter is incremented. When the second sensors sense the vehicle the counter is added to “vehicle count” list and the previous counter...

Agricultural vehicle navigation includes both on-road and on-field operations. The objective for on-road navigation is to guide the vehicle traveling on paved or prepared road according to a scheduled path plan, and for on-field guidance is to guide the vehicle following crop rows without overrun on crops. In this paper, the authors have presented an on-field navigation system with redundant se...

Winter conditions are dominating the road traffic platform in the Northern Scandinavia, and the weather services play an important role in successful winter road traffic operations. Intelligent Road project is contributing towards tackling this challenge and aims to support the development of business community in Northern Scandinavian region by road safety provision via vehicular networking ba...
