【摘要】：针对限量式单通道双向通行控制问题,基于GPS车流感知数据提出了一种端限量式单通道双向自适应通行控制方法。通过在单通道及两端划设扫描区、等候区、单通道内三大类区域,利用GPS定位数据实时感知分析车辆在单通道两端行驶的10种状态,构建了单通道车辆通行控制策略分析模型,对车流数据进行动态汇总和饱和度分析,然后根据"按需分配"和"端总量控制"策略提出了一种自适应双向通行信号控制策略,在此基础上研发了端限量式双向通行自适应信号控制系统.最后利用某大型露天矿单道平硐进行了实例验证,应用表明:该方法能够有效控制单通道车辆的双向限量通行,避免了车辆运输过程中的行驶冲突,减少了车辆"空等"时间和油耗,提高了单通道通行效率,大大提高了车辆的运输效率.
[Abstract]:Aiming at the problem of limited single channel bidirectional traffic control, based on GPS traffic perception data, this paper presents an end limited single channel bidirectional adaptive traffic control method. In three major regions of a single channel, using GPS positioning data to analyze the 10 states of vehicle driving at both ends of a single channel in real time, a traffic control strategy analysis model of a single channel is constructed, and the vehicle flow data are dynamically summarized and saturation analyzed. Then an adaptive two-way traffic signal control strategy is proposed according to the strategies of "distribution according to demand" and "end total quantity control". On the basis of this, an adaptive signal control system is developed. Finally, an example of a large open-pit tunnel is used to verify the method. The application shows that the method can effectively control the two-way limited traffic of a single channel vehicle. It avoids the conflict in the vehicle transportation process, reduces the time and fuel consumption of the vehicle, improves the efficiency of the single passage and greatly improves the efficiency of the vehicle transportation.
