This ensures that conditions are up to date for future selections and creates a <br />repository of information to aid in planning. <br />Prioritization <br />Within Lucity the option is available to prioritize pavement projects for rehabilitation based on six main <br />criteria: PCI, Cost of Deferral, Pavement Strength, Pavement Type, Functional Class, and the Area of a <br />segment. Depending on the goals set forth at the beginning of the project these criteria can be weighted <br />differently based on their definition to create an overall priority factor for a project. Additional details <br />on these factors are available in section 4.2. <br />Project planning <br />The ability to plan work as needed allows the management program to better reflect the realities of a <br />paving program. Certain constraints may be applied to funds that require their use within a certain year <br />and activities relating to other assets may dictate the time and type of work to be performed. Lucity <br />allows for predefined projects to be entered into the management plan to account for work that is <br />IMS Pavement Management Report Louisville, CO 2022 Page 17 <br />
