基于道路的行驶时间信息的提供通常依赖于从嵌入在路面上的感应回路收集的速度数据。虽然感应回路通常安装在城市高速公路上，但它们既没有配置也没有理想的位置来提供主干道上的速度数据。因此，向道路使用者传播动态的全网络旅行信息可能需要其他数据收集技术。本综述考虑了使用手机作为交通探针的实践状况，评估了这种数据收集选项的前景，并确定了可能对使用手机作为探针获取实时交通信息产生影响的未解决问题。使用移动电话作为交通探测器很有吸引力，因为在大多数城市地区，必要的基础设施已经到位。通过被动监控数据在移动电话网络中的传输，可以获得交通速度信息。国际经验为手机作为交通探测器的潜力提供了令人鼓舞的迹象。尚待解决的问题包括公众对隐私的潜在担忧、对移动电话使用对道路安全影响的日益认识，以及更好地了解从移动电话探测器获得的数据质量的必要性。
Abstract The provision of road‐based travel‐time information often relies on speed data collected from inductive loops imbedded in the pavement. While inductive loops are commonly installed on urban freeways, they are neither configured nor ideally located to provide speed data on arterial roads. Dissemination of dynamic, network‐wide travel information to road users is, therefore, likely to require alternative data collection techniques. This review considers the state of practice in relation to using mobile phones as traffic probes, assesses the prospects for this data collection option and identifies unresolved issues that may have implications for obtaining real‐time traffic information using mobile phones as probes. The use of mobile phones as traffic probes is appealing because the necessary infrastructure is already in place in most urban areas. Traffic speed information can be obtained by passively monitoring data transmission in the mobile phone network. International experience provides encouraging signs about the potential of mobile phones as traffic probes. Issues still to be resolved include potential public concerns about privacy, growing awareness of the road safety implications of mobile phone use and the need to understand better the quality of the data obtained from mobile phone probes.
