To evaluate the effectiveness of roadway policies for lighting and marking of farm equipment in reducing crashes in Illinois, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, South Dakota and Wisconsin.
In this ecological study, state policies on lighting and marking of farm equipment were scored for compliance with standards of the American Society of Agricultural and Biological Engineers (ASABE). Using generalized estimating equations negative binomial models, we estimated the relationships between lighting and marking scores, and farm equipment crash rates, per 100 000 farm operations.
A total of 7083 crashes involving farm equipment was reported from 2005 to 2010 in the Upper Midwest and Great Plains. As the state lighting and marking score increased by 5 units, crash rates reduced by 17% (rate ratio=0.83; 95% CI 0.78 to 0.88). Lighting-only (rate ratio=0.48; 95% CI 0.45 to 0.51) and marking-only policies (rate ratio=0.89; 95% CI 0.83 to 0.96) were each associated with reduced crash rates.
Aligning lighting and marking policies with ASABE standards may effectively reduce crash rates involving farm equipment.
评估伊利诺伊州、爱荷华州、堪萨斯州、明尼苏达州、密苏里州、内布拉斯加州、北达科他州、南达科他州和威斯康星州关于农用设备照明和标识的道路政策在减少事故方面的有效性。
在这项生态学研究中，对各州关于农用设备照明和标识的政策进行评分，以确定其是否符合美国农业与生物工程师协会（ASABE）的标准。使用广义估计方程负二项式模型，我们估计了照明和标识评分与每10万次农业作业中农用设备事故率之间的关系。
2005年至2010年期间，美国中西部上游地区和大平原地区共报告了7083起涉及农用设备的事故。随着州照明和标识评分每提高5个单位，事故率降低17%（率比=0.83；95%置信区间0.78至0.88）。仅照明政策（率比=0.48；95%置信区间0.45至0.51）和仅标识政策（率比=0.89；95%置信区间0.83至0.96）均与事故率降低相关。
使照明和标识政策符合ASABE标准可能有效降低涉及农用设备的事故率。
