Stop and go traffic that leads to oscillate traffic flow frequently is observed on congestion flow. Unexpected reasons such as lane – changing maneuvers, lower speeds of leader vehicle and moving bottleneck cause stop and go traffic and amplifying delay and environment impacts. Stop and go traffic exactly can’t be modeled by traffic models, and also car following models based on kinematic flow ...

According to the forensic statistics, in Iran, 26 percent of those killed in traffic accidents are motorcyclists in recent years. Thus, it is necessary to investigate the causes of motorcycle accidents because of the high number of motorcyclist casualties. Motorcyclists' dangerous behaviors are among the causes of events that are discussed in this study. Traffic signs have the important role of...

vehicle crashes are amongst the major causes of mortality and results in losses of lives and properties. alarge number of the vehicle crashes occur on rural roads. accidents become more noteworthy in two-laneroads due to going and coming traffic. therefore, prediction of crashes and their causes are considerablyimportant to reduce the number and severity of the accidents. the safety index is a ...

image analysis is an image processing technique that aims to extract features or information from images. image analysis in medicine has a special place because is a basis for disease diagnosis for physicians. electrophoresis is a laboratory separating technique. electrophoresis images are created during the electrophoresis process. serum protein and hemoglobin electrophoresis test are the most...

A new operational perspective on fundamental concepts related to customers, service, and value differs from servicedominant logic in its approach to service systems, value creation, value co-creation, service interactions, value facilitation, and value constellations. This perspective leads to two new tools for supporting service system design: 1) A “value blueprint” uses a swimlane representat...

Sir,—I refer to the recent review by Phillips, Daborn and Hatch [1]. Between 1991 and 1993 the Department of Anaesthetics in Newcastle examined the problem of preoperative fasting intervals for children presenting for routine surgery. An initial audit revealed that many children were undergoing prolonged fasts before anaesthesia. After reviewing the literature [2], 8 clear fluid fast of 2 h was...

OBJECTIVE This paper's first objective is to determine whether motor priming assistance (consisting of directional steering wheel vibrations) can be of some benefit compared with more traditional auditory (lateralized sound) or vibratory (symmetric steering wheel oscillation) warning devices. We hypothesize that warning devices favor driving situation diagnosis, whereas motor priming can improv...

When an on-board system detects a drift of a vehicle to the left or to the right, in what way should the information be delivered to the driver? Car manufacturers have so far neglected relevant results from Experimental Psychology and Cognitive Neuroscience. Here we show that this situation possibly led to the sub-optimal design of a lane departure warning system (AFIL, PSA Peugeot Citroën) imp...

Bridge weigh-in-motion (BWIM) serves as a method to obtain the weight of passing vehicles from bridge responses. Most BWIM systems proposed so far rely on measurement global vibration data, usually strain, determine vehicle load. However, because bridge’s response is sensitive all bridge, vibration-based techniques suffer inaccuracy in case where multiple are present bridge. In this paper, data...
