According to the World Health Organization, more than one million road traffic deaths occur every year throughout the world. In order to cope with this challenge, many countries have established quantified road safety targets backed up with comprehensive safety strategies. Road safety targets need to be based on reliable forecasting methods. Following the pioneering work by Elvik (2010), this p...

the previous studies show that a high percentage of traffic accidents take place in two-lane rural highways and most of which happen at horizontal curves. meanwhile the horizontal alignment is often subject to hard topographic conditions where because of economic aspects designers are forced to design horizontal curves at grades. vertical angle of longitudinal slope reduces the normal force of ...

Differences in driving behavior due to the presence of users familiar/unfamiliar with the road are commonly considered in both road design (guidelines for road design) and traffic engineering (calculation of the equivalent traffic flow). However, although considered, the matter is largely unexplored: there is a lack of theoretical foundations and data on determining the impact of route familiar...

This paper presents a vision based road boundary detection based on the combination of dynamic programming and 2nd order polynomial approximation. The initial estimate of the most likely road boundaries are obtained by a modified dynamic programming on a cost field defined on the edge image. A second order polynomial is fit to the initial coarse estimate of road boundaries to obtain a refined e...

Synopsis Several researches have pointed out that optical illusions may occur when the horizontal curve is combined with a vertical curve. Crest and sag combinations can cause a significant different driver's behaviour compared to the behaviour adopted on the horizontal curves on flat grade. In particular the literature reports the hypothesis that horizontal curves appear sharper or flatter whe...

Developing a vision based, efficient and automatic lane detection system from a moving vehicle is a challenging task mainly due to poor quality of lane markings, occlusion created by traffic, complex road geometry and nevertheless, the non-existence of unique models. The focus of this paper is to detect line or curve like segments from a video image taken from moving vehicle and merge them to d...

Vehicle-to-Vehicle (V2V) communication channel measurements were carried out in different environments such as urban, suburban, rural, highway, tunnel, and overpass. The roads these have generally flat terrain. However, there are horizontal or vertical curve that been little focused the literature. In this study, we performed two V2V on a vertical-curve road rural environment to show how receiv...

This paper presents a high accuracy stereovision system for obstacle detection and vehicle environment perception in various driving scenarios. The system detects obstacles of all types, even at high distance, outputting them as a list of cuboids having a position in 3D coordinates, size, speed and orientation. For increasing the robustness of the obstacle detection the non-planar road model is...

-Road pricing is widely advocated as a solution to congestion problems The underlying theory is well developed, and we even have the technology to implement it without toll booths Only political barriers remain Decision makers are reluctant to retrofit tolls on existing highways because they do not know what circumstances might make such an action acceptable to the pubhc This paper develops a g...

To facilitate the damping matching of dampers for vehicle passive suspensions, this paper proposes an analytical matching method of the optimal piecewise linear damping characteristics curve. Based on the vehicle vibration model, taking the suspension dynamic deflection as the constraint, by the vibration acceleration and the wheel dynamic load, an objective function about the relative damping ...
