COVID-19大流行导致的社交距离要求对公共交通造成了不成比例的影响。诸如轻松售票和拥挤评估等技术有可能提高安全性，并为交通用户注入信心。这些技术的一个关键组成部分是能够检测公共汽车车辆内乘客的存在，以及他们在车辆内的大致位置。我们提出了一项初步研究，展示了一种使用低功耗蓝牙（信标）系统的潜力，该系统放置在车内，以定位车辆长度范围内的乘客，精度优于1米。基于这些初步结果，我们正在进行一项长期实验，将从使用校园交通系统的乘客那里收集来自BLE信标的RSSI数据（以及GPS和惯性数据）。
Public transit has been affected disproportionately by the social distancing requirements consequent to the COVID-19 pandemic. Technologies such as effortless ticketing and crowdedness assessment have the potential to increase safety and instill confidence for transit users. One key component of these technologies is the ability to detect the presence of a passenger inside a bus vehicle, as well as their approximate location within the vehicle. We present a preliminary study demonstrating the potential of a system that uses Bluetooth Low Energy (beacons), placed inside a vehicle, to localize a passenger within the length of the vehicle with an accuracy better than 1 meter. Based on these preliminary results, we are working on a long-term experiment that will collect RSSI data from BLE beacons (as well as GPS and inertial data) from passengers using the transit system of our campus.
