ABSTRACT
The current paper deals with the debate over centralization versus decentralization in road safety management, and specifically in traffic law enforcement. We address the case study of Spain, where a single traffic law acquis is enforced by two systems: road policing decentralized for some regions and national road policing for all others. Our econometric findings reveal that the Spanish regions with centralized traffic policing present better safety figures, which might be useful for reinforcing the coordinated performance of road safety policy in other traditionally decentralized countries. Furthermore, our evidence indicates that cautious analyses have to be carried out on a case-by-case basis.
DATA AVAILABILITY STATEMENT
The data that support the findings of this study were derived from the following resources available in the public domain: (1) Accidents on interurban roads; Fatalities on interurban roads; and Driver census (exposure variable), all from the Spanish General Traffic Directorate Yearbook. (2) Decentralization, from the Spanish Ministry of Internal Affairs. (3) Unemployment rate; Average age; Ratio of population in capital city; Motorization rate; Tourists; and Per capita GDP, all from the Spanish National Statistics Institute (INE). (4) Highways ratio, from the Spanish Ministry of Transport, Mobility, and Urban Agenda. (5) Precipitation, from the Spanish State Weather Agency). (6) Population density, from Eurostat. (7) Hospital density, from the National Hospitals Catalog – Spanish Ministry of Health, Consumer Affairs, and Social Welfare (see ).
