Cities and counties have smaller budgets compared to State Departments and the nature of their networks is different in respect to functionality and size. Roadway segments are smaller and a large portion of the network consists of residential streets. Often, cities manage a large portion of their Maintenance and Rehabilitation (M&R) work in-house. For more efficient implementations, cities or counties prefer to work more on continuous segments than particular sections and would benefit from using models to group together smaller adjacent projects. This paper proposes a framework to implement a more practical project level M&R for cities and counties. The high-level phases of a common pavement management system (PMS) life-cycle are: I) Performance Data Process, II) Decision Trees, and III) Project Selection and Periodization. However, for smaller agencies like cities or counties an additional phase is proposed in order to create projects that are more efficient to execute in the field: IV) Smart Project Grouping. Sending a crew and machinery and blocking the streets for maintenance work is costly. If the projects are scattered, it results in extra costs both for the agency and the road user. A Smart Project Grouping Model would analyze economies of scale problems such as these while also considering network constraints such as limited budgets and resources available within the administrative unit. To illustrate this approach, a case study of the city of Austin, Texas is presented and discussed. Results show that the model has significant impact on reducing maintenance costs and costs associated with blocking the streets for M&R work.
