25 years of providing evidence on road safety interventions at the city level.

Road traffic injuries are a significant public health concern, ranking among the leading causes of mortality and disability-adjusted life years lost globally, especially among the young population. Traditionally, road safety has been approached predominantly from a healthcare standpoint, with limited interventions from a comprehensive public health perspective. In Barcelona, the Agència de Salut Pública (Public Health Agency) has been monitoring road traffic injuries and evaluating road safety interventions since the late 1990s.

Effectiveness of a Road Traffic Injury Prevention Intervention in Reducing Pedestrian Injuries, Barcelona, Spain, 2002-2019.

This study aimed to evaluate the effectiveness of the Safe Routes to School (SRTS) intervention in Barcelona, Spain, at reducing the number of road traffic collisions and injuries in the school environment. It was a pre-post, quasi-experimental evaluation with a matched comparison group. Road traffic injuries were significantly reduced in the intervention schools-especially among school-age pedestrians-but not in the comparison schools.

Methods to evaluate the effectiveness of advanced stop lines for motorcycles in improving road safety.

In Barcelona, Advanced Stop Lines (ASL) for motorcycles, were implemented since 2009. This paper aims to describe the process followed in determining the best statistical model to analyse the effectiveness of ASL in preventing road traffic injury collisions. A quasi-experimental design of an evaluation study of an intervention with comparison group was performed.

Head-on crashes on two-way interurban roads: a public health concern in road safety.

Objective: To describe the magnitude and characteristics of crashes and drivers involved in head-on crashes on two-way interurban roads in Spain between 2007 and 2012, and to identify the factors associated with the likelihood of head-on crashes on these roads compared with other types of crash.

Methods: A cross-sectional study was conducted using the National Crash Register. The dependent variables were head-on crashes with injury (yes/no) and drivers involved in head-on crashes (yes/no).

Effect of neighbourhood motorization rates on walking levels.

Background: Motorized traffic may discourage people walking. This study analyses the influence of motorization on pedestrian mobility in the neighbourhoods of a European city, controlling for environmental, sociodemographic, mobility and road safety characteristics of the neighbourhood in which each trip was made.

Methods: Cross-sectional ecological study using the 38 neighbourhoods of Barcelona as the unit of analysis.
