Twitter, among other social media platforms, has become more popular over time. Social media platforms underpin the way scholars share ideas, propagate the latest emergence of evidence, and adopt new practices, by providing a virtual platform for interacting, socializing, and sharing information from academic conferences with the outside world beyond the physical location. The Transportation Research Board Annual Meeting (TRBAM) is the largest annual conference for transportation engineering and science, and the hashtag for the conference, #TRBAM, was used first in 2009. This paper aims to perform an observational study based on the interactions on Twitter surrounding this hashtag by collecting all original #TRBAM tweets for 12 years (2009–2020). A general trend in the data is that the quantitative measures (tweets, retweets, and favorites) are all much higher during the conference month compared with other months. Top trending topics included: transit, safety, bike or non-motorized mode of transportation, data, and freight. Overall, the communication pattern shows more dispersion than the central tendency. The findings of this study highlight the need to implement and improve strategies to help transportation research communities encourage continuous and active participation during and after conferences. More active engagement among attendees will help maintain the momentum of information sharing and expand the traffic safety platform globally.

随着时间的推移，Twitter 以及其他社交媒体平台变得越来越流行。社交媒体平台提供了一个虚拟平台，用于与物理位置之外的外部世界进行互动、社交和共享学术会议信息，从而支持学者分享想法、传播最新证据和采用新实践的方式。交通研究委员会年会 (TRBAM) 是交通工程和科学领域最大的年会，会议的主题标签 #TRBAM 于 2009 年首次使用。本文旨在根据 Twitter 上的互动进行观察性研究通过收集 12 年（2009-2020 年）的所有原始 #TRBAM 推文来围绕此主题标签。数据中的一个总趋势是定量测量（推文、转推、和最爱）在会议月份都比其他月份高得多。热门话题包括：交通、安全、自行车或非机动运输方式、数据和货运。总体而言，传播模式表现出比集中趋势更大的分散趋势。这项研究的结果强调了实施和改进策略的必要性，以帮助交通研究界鼓励会议期间和之后的持续和积极参与。与会者更积极的参与将有助于保持信息共享的势头，并在全球范围内扩展交通安全平台。
