Road Investment and Traffic Safety: An International Study Calvo Poyo, Francisco Javier Navarro-Moreno, José Oña López, Juan José De Road safety road accidents road investment The aim of this study is to analyse whether the economic resources invested in roads—both investment in construction and expenditure on maintenance and conservation—have any influence on road fatality rates. Since this is a complex problem, and because there are many factors that can influence the fatality rate, other variables related to specific transport, socioeconomic and meteorological factors are also considered. The study was carried out using a panel data model, modelling road mortality as a function of 12 variables. The scope of the study is international, focusing on the interurban road network. Data were collected from 23 European countries for the period 1998–2016. The main results obtained are that both expenditure on road maintenance and conservation and the proportion of motorways in the total road network contribute to reducing road mortality. Contrariwise, greater investment in construction leads to an increase in the fatality rate. 2020-09-01T06:50:06Z 2020-09-01T06:50:06Z 2020-08-06 journal article Francisco Calvo-Poyo, ,José Navarro-Moreno, and Juan de Oña.
