GUERRERO AGUILERA, Sergio Andrés. Considering road safety on long-term investment strategic plans. Case study: National Route 27, Costa Rica. Infraestructura Vial [online]. 2015, vol.17, n.29, pp.13-23. ISSN 2215-3705.

The work presented here is focused on develop investment guidelines on road safety, in order to incorporate it into a more comprehensive investment plan for a case study (Route 27 San Jose -Caldera, in Costa Rica).

The element of road safety was incorporated to the investment plan through a detailed accident analysis. The analysis developed included: classification by type of accident, determination of accident concentration sections (TCA, for its acronym in Spanish), corroboration of the existence of deficiencies in road infrastructure in each TCA by road safety assessments and field evaluations of road safety related parameters, generating investment guidelines and determination of effectiveness and cost countermeasures based on the frequency and severity of each type of accident.

For each TCA was generated a list of deficiencies in infrastructure, it was able to establish an order of priority of investment and countermeasures intervention for the classification of accidents defined. The results will generate technical inputs for investment policies and resource allocation of road safety. It will contribute to take decisions in order to solve in strategically way the question like How ? and Where ? invest road safety resources.

Keywords : Asset management; road safety; accident concentration sections; prioritization; invesment.
