This study sought to identify opinion-leading U.S. cities in the realm of safe transportation systems by surveying road safety professionals and asking them to identify places that served as models for road safety.
Using a purposive sampling methodology, we surveyed professionals employed in road safety-related professions (e.g., transportation engineering, planning, public health, law enforcement, and emergency response). Using 183 professionals' complete responses, we carried out social network analysis to both describe the structure of intermunicipal advice-seeking patterns among road safety professionals and identify those municipalities with relatively high degrees of influence.
We discovered a large intermunicipal monitoring network related to improving road user safety. Half of the network ties (50.4%) crossed regional U.S. census boundaries. Social network statistics informed the identification of 7 opinion-leader and 4 boundary-spanning municipalities.
This study indicated a large intermunicipal monitoring network, half of which crossed regional boundaries. Road safety professionals have formed a country-spanning example-following network on the topic of improving road user safety in the United States. Researchers and intervention teams can tap into this network to accelerate the uptake and spread of evidence-based road safety practices.
本研究旨在通过对道路安全专业人员进行调查，询问他们哪些地方可作为道路安全的典范，从而找出美国安全交通系统领域的引领性城市。
我们采用立意抽样方法，对从事道路安全相关职业（如交通工程、规划、公共卫生、执法和应急响应）的专业人员进行了调查。利用183名专业人员的完整回复，我们进行了社会网络分析，以描述道路安全专业人员之间市际咨询模式的结构，并识别出那些具有较高影响力的城市。
我们发现了一个与提高道路使用者安全相关的大型市际监测网络。该网络关系的一半（50.4%）跨越了美国人口普查区域边界。社会网络统计结果有助于识别出7个引领性城市和4个跨越边界的城市。
本研究表明存在一个大型市际监测网络，其中一半跨越了区域边界。在美国，道路安全专业人员围绕提高道路使用者安全这一主题形成了一个覆盖全国的效仿榜样网络。研究人员和干预团队可以利用这个网络来加速基于证据的道路安全实践的采用和推广。
