There is a consensus on the importance of rural roads when increasing economic growth and household welfare. However, little is known regarding the positive effect these roads will have on the welfare of households in Viet Nam. This paper aims to measure that effect. It is known that rural roads help households increase per capita income and working hours. The estimated impact of these roads on...

No-passing zone crashes constitute a sizable percentage of the total crashes on two-lane rural roads. A detection and warning system has been devised and implemented at a no-passing zone site on route 114 of Southwest Virginia to address this problem. The warning system aims at deterring drivers from illegally conducting a passing maneuver within the no-passing zone area. The violating driver i...

Road departure is one of the main causes single vehicle and frontal crashes. By implementing lateral support systems, a significant amount these accidents can be avoided. Typical are normally occurring due to unintentional lane where driver drifts towards across line identifying edge lane. The Lane Support Systems (LSS) uses cameras “read” lines on road alert if car approaching lines. Anyway, d...

OBJECTIVES In urban settings, pedestrian fatalities and injuries are concentrated on major roads. This study aims to describe urban intersections with major roads (arterials and collector roads) and explore the association between intersection characteristics and injured pedestrians. METHODS From a stratified random sampling in Montréal, Quebec, 512 intersections were selected and their chara...

In this paper, we present an efficient lane detection and tracking algorithm for wide-baseline stereo vision systems with cameras mounted on the host vehicle. The main purposes of the vision system are host vehicle localization and lane shape recognition for advanced driver assistance tasks on highways and country roads with visible lane boundary markings. This is achieved via the 3D geometrica...

Traffic conditions in Indian urban and sub urban roads are in many ways not ideal for driving. This is due to faded and unmaintained lane markings. Therefore driving sometimes becomes difficult. Due to inappropriate markings of the roads, it is difficult to track the lane marking using conventional lane marking algorithms. Therefore the issue of Lane tracking with road boundary detection and ot...

For an automatic co-pilot designed to assist the driver while operating a vehicle on wellmarked or unmarked roads algorithms were developed for recognizing and tracking the driving lane used by the vehicle. A video camera is used as a sensor. Each algorithm has been implemented on one parallel processor of the multiprocessor robot vision system BVV 3. The method of controlled correlation is use...

Road information as a type of basic geographic information is very important for services such as city planning and traffic navigation, as such there is an urgent need for updating road information in a timely manner. Scholars have proposed various methods of extracting roads from remote sensing images, but most of them are not applicable to rural roads with diverse materials, large curvature c...
