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 (n = 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.

超速是导致严重损伤与死亡的主要风险因素之一。然而，超速行为在全球范围内仍普遍存在。本研究以阿根廷布宜诺斯艾利斯市为研究区域，旨在探究当地驾驶员超速行为的相关影响因素。研究于2021年分两阶段，对该市10个观测点位的34967辆机动车开展观测，数据采集覆盖一周内的不同时段与日期。观测点位均未设置交叉口、交通信号灯、减速带及测速摄像头，以排除交通管控设施对驾驶行为的干扰，确保驾驶员可自由操控车速。本次研究收集了车速、驾驶员属性以及车辆类型等相关数据。通过逻辑回归分析，本研究识别出与超速行为显著相关的影响因素。观测结果显示，15.3%的被测机动车存在超速行为。限速40km/h的路段，超速车辆占比显著高于限速60km/h的路段。在本地支路道路上，77%的车辆行驶车速超过30km/h；而在城市主干道上，30%的车辆车速超过50km/h。商用及民用摩托车的超速占比均高于其他所有类型的机动车。女性驾驶员、60岁以上成年驾驶员以及驾车时使用手机的驾驶员，其超速行为的发生率相对更低。强化提升道路限速合规性的相关策略至关重要，而针对摩托车骑手的干预措施应作为交通安全工作的优先事项。
