ABSTRACT

Instrumented bikes are a critical tool to understanding cyclist behaviour and preferences to incorporate cycling into modelling, designing, and planning the transportation system. Literature using instrumented bikes for transportation-related research has increased in popularity, especially in the last 6 years. As these studies are growing in number and maturity, now seems a good time to review how the bikes have been used, choices of sensors and methodology, and where there are gaps to be filled by future work. Therefore, the objectives of this literature review are to 1) discuss sensor choice in relation to methodology, 2) review findings from topics studied using instrumented bikes, and 3) discuss gaps in the literature. Two databases were searched for transportation-based literature using instrumented bikes with a total of 75 articles meeting the inclusion criteria. The literature was organised into nine focus areas with the most common topics being E-bikes, vehicles passing cyclists, and critical events. The results show that instrumented bikes are versatile tools that can shed light on a variety of aspects of cyclist behaviour and safety as well as how to maintain the system for them. Various sensors were used for these studies, but cameras, GPS, and accelerometers were the most common. The review highlights the importance of study technique (naturalistic vs quasi-naturalistic vs other) on sensor choice with GPS and/or cameras being critical to any naturalistic study. However, GPS and cameras are the most challenging data types to work with due to difficulty and the time-consuming nature of processing the data. The variation in sensors also suggests some need to standardise set-ups for comparison of data across international contexts. Areas for future research are also discussed, including a new perspective for passing-distance studies and incorporating instrumented bikes into the connected vehicle/infrastructure space.

摘要

仪表车是了解骑车人的行为和偏好的重要工具，可以将骑行纳入建模，设计和规划运输系统。使用仪表自行车进行与交通相关的研究的文献越来越流行，尤其是在过去的6年中。随着这些研究的数量和成熟度的增长，现在似乎是时候回顾一下自行车的使用方式，传感器的选择和方法，以及未来的工作需要填补的空白。因此，本文献综述的目的是：1）讨论与方法相关的传感器选择； 2）回顾使用仪器自行车研究的主题中的发现； 3）讨论文献中的空白。在两个数据库中搜索了使用自行车的基于交通的文献，共有75篇符合纳入标准的文章。这些文献分为9个重点领域，最常见的主题是电动自行车，骑自行车的人通过的车辆和重大事件。结果表明，仪表自行车是多功能的工具，可以阐明骑自行车者的行为和安全性的各个方面，以及如何为他们维护系统。这些研究使用了各种传感器，但是最常见的是照相机，GPS和加速度计。该评论强调了研究技术（自然与准自然与其他）在传感器选择上的重要性，GPS和/或相机对于任何自然研究都是至关重要的。然而，由于处理数据的难度和耗时的特性，GPS和照相机是最具挑战性的数据类型。传感器的变化也表明需要标准化设置，以便在国际范围内比较数据。还讨论了未来的研究领域，包括通过距离研究的新观点以及将仪表自行车纳入连接的车辆/基础设施空间的新观点。
