At least 70 US cities have now introduced ciclovías-large-scale street closures to promote physical activity-joining numerous other cities worldwide that have implemented ciclovías in efforts to improve population health. We assessed the impact of Summer Streets, a New York City program in which 6.9 contiguous miles of urban streets were closed to traffic and opened for walking, cycling, and group activities, such as dancing and yoga, on population physical activity levels. Screen line counts were used to estimate attendance, and a street intercept survey was conducted to assess demographic characteristics of participants, baseline adherence to physical activity recommendations, and type and duration of physical activity at Summer Streets. In addition, a traffic study was used to determine if there were vehicular traffic delays as a result of the program. About 50,000 people participated in Summer Streets; among participating New Yorkers, bicyclists averaged 6.7 miles, runners 4.3 miles, and walkers 3.6 miles, equivalent to 72-86 min of moderate physical activity. Among New Yorkers attending Summer Streets, 24 % reported that they did not routinely engage in moderate- or vigorous-intensity physical activity. These non-routine exercisers engaged in the equivalent of 26-68 min of moderate-intensity physical activity at Summer Streets. Summer Streets served as an enticement for New Yorkers, including those who did not ordinarily meet physical activity recommendations, to engage in physical activity. There were no significant vehicular traffic delays during the program.
目前，美国至少70个城市已经推出了自行车专用道（大规模封闭街道以促进体育活动），加入了全球众多其他实施自行车专用道以改善民众健康的城市行列。我们评估了纽约市“夏日街道”项目的影响，该项目封闭了6.9英里相连的城市街道，禁止车辆通行，开放供人们步行、骑自行车以及开展舞蹈和瑜伽等集体活动，评估其对民众体育活动水平的影响。通过屏幕线计数来估计参与人数，并进行街头拦截调查，以评估参与者的人口统计学特征、对体育活动建议的基线依从性以及在“夏日街道”的体育活动类型和时长。此外，还进行了一项交通研究，以确定该项目是否导致了车辆交通延误。约5万人参与了“夏日街道”项目；在参与的纽约人中，骑自行车的人平均骑行6.7英里，跑步者平均跑4.3英里，步行者平均走3.6英里，相当于进行了72 - 86分钟的中等强度体育活动。在参加“夏日街道”项目的纽约人中，24%报告称他们平时不经常进行中等强度或剧烈强度的体育活动。这些非日常锻炼者在“夏日街道”进行了相当于26 - 68分钟的中等强度体育活动。“夏日街道”吸引了纽约人参与体育活动，包括那些通常未达到体育活动建议标准的人。在项目实施期间，没有出现明显的车辆交通延误。
