[Risk factors for provoking collisions between cyclists and pedestrians in Spain, 1993-2011].
OBJECTIVE
To identify and quantify the factors depending on pedestrians, cyclists and the environment associated with the risk of causing a collision between a cyclist and a pedestrian in Spain from 1993 to 2011.


METHODS



METHODS
retrospective case series.


METHODS
1228 pedestrian-cyclist pairs involved in the same number of collisions in an urban area, only one of whom committed an infraction.


METHODS
Register of Traffic Accidents with Victims, supported by the Spanish Traffic General Directorate.


METHODS
committing an infraction (yes/no), age, sex, helmet use (cyclist), hour, type of day, year, existence of sidewalks, place of the accident, and priority regulated.


METHODS
logistic regression model to estimate the strength of the association between the pedestrian's responsibility and independent variables. The association with the cyclist's responsibility was assessed by reversing the value of the odds ratios obtained.


RESULTS
In both groups of users, the risk of causing a collision was higher in extreme ages. Female cyclists had a slightly higher risk than male cyclists, while the use of a helmet had a protective effect. The risk of the pedestrian causing an accident was higher in the absence of sidewalks. Cyclists more frequently provoked accidents in crosswalks.


CONCLUSIONS
We recommend the implementation of safety campaigns aimed at pedestrians and cyclists, with special attention paid to the youngest and older people. Interventions for correct road use would also be advisable.
