Car free days and sustainable physical activity.

A systematic review examined the health benefits associated with car free events and health outcomes (e.g., air pollution, physical activity, noise) (1). Among 23 included papers, one collected device-measured physical activity data (2), two estimated the physical activity levels of population with surveys (3,4).

Ciclovia is a weekly event created in Bogota, Colombia. Every Sunday, about 121 kilometers (70 miles) of roads are closed to motorized traffic. I can easily understand this impact with the following video.

The Ciclovia initiative was associated with a moderate and vigorous physical activity increase of 6 minutes and a sedentary behaviour reduction of 19 minutes among children participating (2). Most Ciclovia participants (adults) reported had low-to-middle educational attainment, and did not own cars. This event was associated with a possible 13% rate of people attaining international guidelines.

Another initiative was examined. Brownville, Texas, USA closes 3 miles (ca. 5 km) of town center streets (4 to 6 times per year). During this car-free event, 17.3% of attendees met weekly recommended physical activity levels.

This low number of included paper is surprising. Authors included papers or reports from grey literature but (maybe) they did not include the papers published in Spanish. Another explanation may be the lack of resources to measure physical activity behaviors (5). For instance, 17 countries of Latin America had a Ciclovia program between 1974 and 2016 (6). Only two articles (in English) was found on this initiative.

Two US studies (not included in this review) investigated the physical activity related behaviours during a Ciclovia program carried out in San Diego and Los Angeles, respectively.

Direct observations were performed in San Diego. It indicated that 85% of attendees were bicycling and 15% were walking. Study participants reported an average of 144 minutes of physical activity during the Ciclovia event. 39% of participated met the physical activity recommendations. Moreover, no significant differences were found between gender, ethnicity, income (7).

The Clovia program was named CicLAvia in Los Angeles (8). This initiative was initiated in 2010, and repeated 4 times per year for 6 miles (ca. 10 km). Physical activity data were collected with video cameras (at 1-mile intervals along the CicLAvia route), GPS “wore” by volunteers following the participants, and questionnaires. The GPS data showed an average traveling distance of 8.68 miles. At a speed of 6 miles/h, it would take 1.45 h to traverse this distance. Authors estimated that a total of 163,000 to 245,000 MET hours was expended by cyclists and a total of 13,500 to 18,000 MET hours was expended by pedestrians. 50% of respondents met the national guidelines of 150 min per week. Nearly 27% of participants said they if they had not been at CicLAvia, they would have stayed home while another 18% said they would have been sedentary.

In health and climate change perspective (9), these events may be a useful temporary solution to:

  • decrease the air/noise pollution exposition,
  • increase the physical activity level of local population,
  • offer a safe experimentation of active transport for all,
  • experiment a city with lower car traffic.
