In this paper, a new lane detection algorithm based on support vector machine (SVM) is presented. This algorithm can overcome the flaws when applying traditional lane algorithms which are only applicable to some special situations. The main steps of this algorithm: road surface extraction by using SVM pattern recognition, image morphology operation, transforming the image into a bird-view image...

• We identify nodes, construct centerlines and determine lanes from smartphone GPS. Smooth, segment-based centerline unbiased by GPS density distribution over lanes. Accurate road width based on an adapted two-stage local outlier factor criterion. Compatible highly accurate estimation of using adaptation GMM. Providing a platform for the extraction lane-level traffic data. The construction rout...

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 ...

In this article, a novel driving behavior recognition system based on a specific physical model and motion sensory data is developed to promote traffic safety. Based on the theory of rigid body kinematics, we build a specific physical model to reveal the data change rule during the vehicle moving process. In this work, we adopt a nine-axis motion sensor including a three-axis accelerometer, a t...

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...
