    Machine Learning-Based Modeling of Celeration for Predicting Red-Light Violations by Mahmoud Masoud

    Published 2024-01-01
    “…The study is based on a thorough analysis of a large dataset that includes a variety of parameters, such as exceeding speed limits, driver age, passenger count, weather, road condition, and temporal factors. Using cutting-edge machine learning methods like AdaBoost and Bagging, predictive models for red-light violations are painstakingly built, achieving remarkable validation accuracies of 90.4% and 90.1%, respectively. …”

    Variable Transmission Range Routing Protocol Based on Vehicle Density in VANET by Rong Cai, Guoan Zhang, Yuebo Wu

    Published 2015-03-01
    “…In order to solve the problem of unstable connectivity and high bit error rate,which are caused by rapid changes in the density of vehicles on the road,while the transmission radius remained unchanged,a variable transmission range routing protocols based on vehicle density in vehicular Ad-Hoc network was proposed.According to different vehicle density,node could adjust the farthest transmission distance and reduce the transmission latency of the message,which could ensure high connection probability of the network.Based on homogeneous poisson point process model,the change conditions of transmission range with different vehicle density were deduced,and its feasible was proved.Furthermore,mathematical calculate formula of average latency was obtained according to the theoretical analysis.At last,variable transmission range routing protocol based on vehicle density and fixed transmission range routing protocol were compared by simulation.The simulated results show that the proposed protocol can be applied in actual environments,and the message can be transmitted fast from source node to destination node under the condition of high connection probability.…”

    Network quality and user perception improvement of high-speed rail scene by Songbai LIANG, Yingwu GUO, Xinwei LI

    Published 2021-03-01
    “…In view of the difficulty in improving the quality of mobile network in high-speed railway scenes and the poor efficiency of conventional methods, a methodology system for improving the perception of mobile communication users was explored in traffic trunk lines, especially in high-speed railway scenes.The methodology system was based on handover chain optimization with the core idea of “primary covering, reasonable reselection and orderly switching”.It adopted a three-layer theoretical structure include covering control firstly, then parameter optimization, and feature loading last.It used idle state and service state data pull graph correlation to determine problem road sections and cells, match the delay parameters of high-speed mobile scenes, load service quality and perception characteristics, and greatly improved the high-speed railway network quality and user perception.This method started from the principle analysis, with practical application, it could effectively solve the network problems, which could be fully extended to other linear scenes.…”
