快速路入口匝道控制交通量阈值研究
Research on Traffic Volume Thresholds for Expressway On-ramp Metering Control
摘要
Abstract
Taking the on-ramp of the First Ring Road(along the Outer Ring Road elevated direction)in Urumqi as the re-search object,three control strategies,namely fixed-time signal control,ALINEA control and ALINEA queue control were im-plemented under different traffic demand levels,with corresponding simulation models established.The results indicate that all three strategies can improve mainline traffic operation conditions but lead to increased on-ramp delay and queue length,among which the fixed-time signal control strategy has a more significant negative impact on on-ramp traffic.Additionally,by gradual-ly adjusting mainline traffic volume and on-ramp traffic volume,the average vehicle delay differences between the no-signal-control strategies and the three strategies are compared,the traffic volume thresholds for each strategy are determined,which provides a theoretical basis for optimizing signal parameters,thereby reducing vehicle delay and improving traffic efficiency.关键词
