Speeding behavior and associated factors in Buenos Aires, Argentina

Excessive speed is a major risk factor for serious injuries and death. However, speeding remains a pervasive problem around the world. This study aimed to investigate the factors associated with speeding behavior in the city of Buenos Aires, Argentina. A sample of vehicles (<i>n</i> = 34,967) from ten locations in the city was observed in two waves during 2021. Measurements were made at different times and days of the week. Observation sites were free of intersections, traffic lights, speed bumps and cameras, allowing drivers to speed freely. Data on speed, drivers and vehicle types were collected. Factors associated with speeding were identified through logistic regression analyses. 15.3% of vehicles were observed to be speeding. Roads with posted speed limits of 40 km/h showed higher speeding compared to 60 km/h roads. 77% of vehicles traveled above 30 km/h on local roads, and 30% above 50 km/h on avenues. Motorcycles, both commercial and private, showed a higher percentage of speeding compared to all other vehicles. Speeding was lower among women, among adults over 60 years of age, and among those using cell phones. It is crucial to strengthen strategies for increased compliance with speed limits. Actions targeting motorcyclists must be a priority.

超速是引发严重受伤与死亡的主要风险因素之一，然而超速问题在全球范围内仍普遍存在。本研究旨在探究阿根廷布宜诺斯艾利斯市驾驶员超速行为的相关影响因素。研究于2021年分两轮对该市10个观测点位的34967台车辆开展观测，观测时段覆盖一周内的不同时间与日期。所有观测点位均未设置交叉口、交通信号灯、减速带与测速摄像头，为驾驶员提供了无额外限速约束的行驶环境。本研究收集了车辆行驶速度、驾驶员信息及车辆类型等数据，并通过逻辑回归分析识别出与超速行为相关的影响因素。经观测，15.3%的车辆存在超速行为。限速40km/h的道路，其超速车辆占比高于限速60km/h的道路。在地方道路上，77%的车辆行驶速度超过30km/h；而在主干道上，30%的车辆行驶速度超过50km/h。商用与私人摩托车的超速占比均高于其他所有类型车辆。女性驾驶员、60岁以上成年人以及正在使用手机的驾驶员，其超速行为占比更低。加强提升限速合规性的相关策略至关重要，而针对摩托车驾驶员的干预措施应作为优先工作事项。
