HDM-4 Based Procedure for Reviewing Condition Performance Targets in the Mexican Road Network

Agencies of the Mexican government responsible for managing the federal road network use the International Roughness Index (IRI) as the main indicator for rating road performance, set intervention thresholds and define performance targets. Although the IRI standards currently employed reflect somehow the international practice and the historical availability of resources, the actual approach followed for selecting those standards has been essentially empirical. In this context, some stakeholders are requiring the adoption of lower IRI limits, forcing responsible agencies to assess the affordability of such a change. Considering the above, a HDM-4 based procedure for analyzing the effects of a given IRI standard on budget requirements and road performance has been developed. This procedure can be summarized as follows; a) Define an IRI standard; b) Using a HDM-4 strategy analysis, obtain an unconstrained work program for a 10-year analysis period; c) Adjust the above program for a given set of restricted budget scenarios; d) Assess the feasibility of each scenario and determine the performance targets that can be achieved. HDM-4 has been used by Mexican road agencies for several years to prepare investment programs, so it has been deemed appropriate to use this tool in developing the proposed procedure.
