Managing Ontario's highway network is a complex task, due to the size of the province, different climatic zones, highway classes and pavement types. The development of the 2nd generation Pavement Management System (PMS/2) for the Ministry of Transportation of Ontario (MTO) was aimed at enhancing the Ministry's pavement management process in the areas of the data management and network level analysis, the latter was based on the development of the Decision Support Subsystem (DSS). In the process of developing and implementing the existing mainframe based PMS, the Ministry has acquired a large amount of experiences in terms of data acquisition, pavement performance index modeling, pavement rehabilitation and engineering decision support models, etc. This paper provides highlights of how these experiences were encompassed in developing the second generation PMS. The paper will also present the main modules in the system in order to facilitate description of the challenges and the approach used in the development of the decision support elements, and how these elements are implemented in PMS/2.
