A driving simulator study was conducted to test the influence of Collision Avoidance Warning System on drivers’ performance. Perceptual load on the road (e.g., vehicles’ congestion) and its sides (e.g., pedestrians’ number) were manipulated, while critical events occurred on the road (e.g., a leading car suddenly slowed down) or initiated from its sides (e.g., a pedestrian crossed the road unex...

An integrated method for road centerline extraction has been proposed in this paper which consists of four main steps. First, the Graph Cut algorithm using proposed similarity function is employed to segment the image, and the segmented image is thresholded to initial binary skeleton. Second, the road skeleton is refined by using a series of morphology operations and shape features. Third, the ...

without any doubt, road safety (rs) needs a precise planning in road accident prevention. rs effects on different fields of the life. therefore, response to this need in order to promote the rs as well as to save more lives is the most asset in each country. in the recent years, statistics have been shown that the numbers of mortalities due to road crashes decreased. this shows the true motion ...

This paper studies the analysis of reductio ad absurdum by Ibn Sı̄nā (known to the Latin West as Avicenna), who was born in 980 in a village near the Bactrian town of Balkh on the Silk Road, and died in 1037 after a career spent moving around within the present boundaries of Iran. References to Ibn Sı̄nā’s writings are to his Arabic texts listed in the bibliography, and are given in the format pa...

This case study of the Argentina Road Safety Project demonstrates how the application of World Bank road safety project guidelines focused on institution building can accelerate knowledge transfer, scale up investment and improve the focus on results. The case study highlights road safety as a development priority and outlines World Bank initiatives addressing the implementation of the World Re...

Automated systems for road crack detection are extremely important in road maintenance for vehicle safety and traveler’s comfort. Emerging cracks in roads need to be detected and accordingly repaired as early as possible to avoid further damage thus reducing rehabilitation cost. In this paper, a robust method for Gabor filter parameters optimization for automatic road crack detection is discuss...

Panacea is a modular system which incorporates a steerable sensor into an existing neural network driving system, ALVINN. A xed camera cannot see the road when it makes sharp bends. For a vision system that builds a map of the road, it is straightforward to point the camera down the road; but ALVINN directly outputs a steering command without generating an intermediate road representation. Insi...

This work presents a hydraulic anti-lock braking system (ABS) for a motorcycle. The ABS has a hydraulic modulator and an intelligent controller. The hydraulic modulator is analyzed, and then equipped on a scooter for road tests. The intelligent controller controls the hydraulic modulator by estimated vehicle velocity to calculate the slip ratio of the wheels in real time. The performance of the...
