In September 1993, Edmonton City Council approved the Terms of Reference for an updated Transportation Master Plan Study. In 1995, it was decided to include pavement management information within the scope of the project. This was made possible by the availability of customized performance prediction models in Version 4.13 of Alberta's Municipal Pavement Management System. Although the MPMS software was designed to run for only a ten year programming period, the data tables were reset at the end of each ten year run to simulate a new set of starting conditions. In this way, it was possible to find: a) the expenditure levels required to maintain current network service levels over the planning horizon, b) the best achievable service levels with unlimited funding, c) the service levels which would result if approved funding trends were maintained, d) the effect of including a reconstruction program on network service levels. Separate runs were made for freeways, arterial truck routes, arterial non-truck routes, collectors, and local streets. Of particular interest was the fact that the existing backlog of rehabilitation and reconstruction needs has a substantial impact on network performance over the longer term. (A)
