Abstract

AbstractMultiple applications of travel time data collection based on the reading of time-stamped media access control (MAC) addresses from Bluetooth-enabled devices have been reported in the literature, and commercial data collection units (DCUs) have been developed and deployed. One characteristic of Bluetooth-based travel time data obtained for travel time sample-generation purposes is that a MAC address is typically read multiple times as a vehicle containing the Bluetooth device travels within the length of road covered by the DCU’s antenna. Such data records of the same MAC address will have different timestamps and received signal strength levels. If the DCUs are installed at arterial intersections to collect travel time samples, this characteristic of MAC address data collection may also be used as the basis for estimating intersection performance. In this research, the use of the time/duration information present in the MAC address data to estimate intersection performance measures is investigate...
基于蓝牙的行车时间数据采集测量交叉口性能
摘要基于从支持蓝牙的设备读取带时间戳的媒体访问控制(MAC)地址的旅行时间数据采集的多种应用已经在文献中得到了报道,商业数据采集单元(dcu)已经开发和部署。基于蓝牙的旅行时间数据的一个特征是,当包含蓝牙设备的车辆在DCU天线覆盖的道路范围内行驶时,通常会多次读取MAC地址。这些相同MAC地址的数据记录将具有不同的时间戳和接收到的信号强度级别。如果将dcu安装在主干道十字路口收集行驶时间样本,则MAC地址数据收集的这一特性也可以作为估计十字路口性能的基础。在本研究中,研究了使用MAC地址数据中存在的时间/持续时间信息来估计交叉口性能措施。
