This paper aims at assessing the effectiveness of the package of road safety measures implemented after road safety was included in the political agenda in the year 2004 on the number of road traffic-injured people in Spain.
An evaluation study was performed using an interrupted time-series design. The study population was people injured in road traffic crashes in Spain between 1 January 2000 and 31 December 2006. The road traffic crashes database of the General Directorate for Traffic was used. The dependent variable was the monthly number of people injured, stratified by sex, age, severity and type of road user. The explanatory variable (intervention) compared the post-intervention period (2004-6) with the pre-intervention period (2000-3). Quasi-Poisson regression models were adjusted, controlling for time trend and for seasonality.
Results show a reduction in the risk of being injured for both men (RR 0.91; 95% CI 0.87 to 0.95) and women (RR 0.89; 95% CI 0.85 to 0.94). Risk reductions were observed across all age groups and all road users, except for pedestrians.
The present study suggests that prioritising road safety reduces the number of people injured in road traffic collisions.
本研究旨在评估 2004 年将道路安全纳入政治议程后实施的一揽子道路安全措施对西班牙道路交通事故受伤人数的效果。
采用中断时间序列设计进行评估研究。研究人群为 2000 年 1 月 1 日至 2006 年 12 月 31 日期间在西班牙因道路交通事故受伤的人员。使用交通总局的道路交通事故数据库。因变量为按性别、年龄、严重程度和道路使用者类型分层的每月受伤人数。解释变量（干预）将干预后时期（2004-6 年）与干预前时期（2000-3 年）进行比较。调整了拟泊松回归模型，控制了时间趋势和季节性。
结果表明，男性（RR0.91；95%CI0.87-0.95）和女性（RR0.89；95%CI0.85-0.94）受伤的风险均降低。除行人外，所有年龄组和所有道路使用者均观察到风险降低。
本研究表明，优先考虑道路安全可降低道路交通事故中受伤人数。
