In this study, we analyse the impact of ridehailing services on traffic accidents with at least one young person dead or seriously injured (16-39 years old) in the municipality of Madrid from 2014 to 2018. To do this, a regresion analysis has been carried out using a Random-Effects Negative Binominal Regression (RENB). The results of the model show that Uber and Cabify services are related to a reduction in urban accidents.
