With the evolution of advanced wireless communication technologies, tremendous efforts have been invested in vehicular networking, particularly the construction of a vehicle-to-vehicle communication system that supports high speed and mobility. In vehicle-to-vehicle communication environment, vehicles constantly exchange information using wireless technology. This paper aims to propose a vehicl...

When driving on lower-category Dutch rural roads without any delineation, drivers are likely to drift off the road with their right-side wheels, thus incurring damage to the pavement edge or even leading to accidents. In two experiments, two types of road-edge delineation, with continuous or dashed edge lines, were compared with two control roads without lines or with only a dashed line on the ...

It’s obvious that road safety is causing large problems and costs in Iran with an enormous impact on the well-being of people, economy and productivity. The yearly number of fatalities and injuries is still unchanged. Motor vehicle injuries lead the list of injury deaths at the all ages during childhood and adolescence, even in children under 1 yrs of age. Understanding the actual of chil...

Intelligent vehicle platoon driving is a process of flexible control based on the coordination between vehicle and highway in intelligent vehicle-highway system. It can improve the velocities and reduce the spacing between vehicles in the platoon, thus, to improve road capacity and road safety. It is the most important for developing intelligent vehicle-highway system to construct intelligent v...

The main problem of vehicle vibration comes from road roughness. An active suspension systempossesses the ability to reduce acceleration of sprung mass continuously as well as to minimizesuspension deflection, which results in improvement of tire grip with the road surface. Thus, braketraction control and vehicle maneuverability can be improved consider ably .This study developeda new active su...

One of the most noticeable trends of the automotive industry in the 1990's is the emerging of active safety technologies. Instead of passive protection and crash worthiness, emphasis has been shifted toward accident prevention and damage reduction using active safety techniques. To develop effective active safety devices, it is necessary to estimate vehicle motions accurately, and reliable road...

This paper describes a real-time road following and road junction detection vision system for autonomous vehicles. Vision-guided road following requires extracting road boundaries from images in real-time to guide the navigation of autonomous vehicles on the roadway. We use a histogram-based pixel classification algorithm to classify road and non-road regions in the image. The most likely road ...

Look-ahead cruise controllers and other advanced driver assistance systems for heavy duty vehicles require high precision digital topographic road maps. This paper presents a road grade estimation algorithm for creation of such maps based on Kalman filter fusion of vehicle sensor data and GPS positioning information. The algorithm uses data from multiple passes over the same road to improve pre...

In this paper, we present a dynamic navigation approach (DNA) that can be combined with GPS receivers, digital maps, and wireless technologies such as DSRC, 802.11p, and WiMAX. By calculating the score, a weighted sum of average vehicle speed, average inter-vehicle distance, road type, and road gain, for each candidate road, the DNA can generate a road score table and choose the road with the h...
