The observational study aimed to estimate the prevalence of speeding on urban roadways and to analyse associated factors.


The study adopted a cross-sectional, observational, roadside-type design, by direct observation of vehicles, drivers, and road conditions in the city of Belo Horizonte from October 24 to November 6, 2012.

Key Findings:

  • The study found that the presence of speed cameras had a great impact on speed at the exact installation points, but failed to ensure compliance with speed limits by a significant share of drivers 200 meters after the cameras

  • The results show that compliance with speed limits and changing individual and community behaviour require more than structural interventions

  • Motorcyclists are the group that speeds the most, which aggravates the vehicle’s inherent risk by increasing the driver’s vulnerability, confirming the need to identify effective and sustainable strategies targeting driving behaviour to improve speed control in developing countries.
