Accidents due to cross the lane (lane departure crash) of achieving 19% of all accidents. These accidents mostly caused because the driver is not concentrating or dozing. A device that can help the driver so that the vehicle does not exit lanes known as Active Lane Keeping Assist (ALKA). ALKA is a subsystem of Advanced Driver Assistance System (ADAS) and is now used in several brands of cars na...
A lane departure warning system is one of the emerging systems for reducing traffic accidents. LDWS is a system designed to warn a driver when the vehicle begins to move out of its lane boundaries on roads. Different techniques to implement LDWS have been surveyed. Implementation of LDWS on different platforms is studied. Refer ences
Introduction The time headway of vehicles is of fundamental importance in traffic engineering applications like capacity, levelof-service and safety studies. Further, the performance of traffic simulation depends on inputs into the simulation process and ‘accurate vehicle generation’ is critical in this context. Thus, it is important to define headway distribution pattern for the purpose of ana...
This manuscript develops a visual lane detection algorithm using the Hough transform to detect strong lines in a road image as candidates for lane boundaries. The search space in the Hough transform is reduced by searching for lane boundaries where they were detected in the previous video frame. The perspective transform is applied to determine the position and orientation of candidate lines, w...
background and aim: traffic accident is one of the main causes of mortality in iran. the damage and injury caused by these accidents threatens human societies severely. rural accidents are often more severe and show harsher consequences because the operational speed is higher on rural roads and highways. world statistics presented by world health organization (who) reveal that about 25 percent ...
Horizontal alignment is a major roadway characteristic used in safety and operational evaluations of many facility types. The Highway Safety Manual (HSM) uses this characteristic in crash prediction models for rural two-lane highways, freeway segments, and freeway ramps/C-D roads. Traffic simulation models use this characteristic in their processes on almost all types of facilities. However, a ...
Are roads key to raising living standards in poor rural areas? This study evaluates the impact of the World Bank–financed Viet Nam rural transport project I, a large-scale rural roads rehabilitation project that aims to reduce poverty. The analysis will focus on the welfare impacts of rural roads as an input to policy discussion about how best to allocate scarce public resources for poverty red...
