人流密集区域道路两翼车位信息远程传送仿真

摘要

在城市人口密度逐渐加大的同时,机动车数量也在迅速地增加,相对于城市有限的空间资源,停车难问题越来越突出,为了缓解这一问题,需要进行人流密集区域道路两翼车位信息远程传送方法的研究.但是采用当前方法进行车位信息远程传送时,无法保障信息传输链路的稳定性,存在车位信息远程传送稳定性差的问题.为此,提出一种基于SF的人流密集区域道路两翼车位信息远程传送方法.该方法先利用SF方法将采集的人流密集区域道路两翼车位信息划分为不同类型的信息节点,将链路保持的时间定义为评价核心链路稳定性的标准,实时地调整各信息节点的传送状态,将信息传送的优先级与接受系统服务的时间联系起来,设定信息远程传送的最小延迟时隙阈值,以此为依据进行人流密集区域道路两翼车位信息远程传送.实验仿真证明,所提方法信息远程传送稳定性高,为解决停车难问题提供了可行的依据.%A remote transmission method of parking information on two sides of road in intensive area based on SF is proposed.The SF method is used to divide collected parking information of two sides of road in intensive area into different types of information nodes.Then,the time of link maintenance is defined as the standard for evaluating stability of core link,so as to adjust the transfer status of each information node in real time.Moreover,the priority level of information transmission is linked with time of accepting system service to set the minimum delay time slot threshold of information remote transmission.On this basis,the remote transmission of parking information on two sides of road in intensive area is carried out.Simulation results show that the proposed method has high stability of remote transmission,which provides a feasible basis for solving the parking problem.
