State within the Scope of Work if PBPD will be used. PBPD is a decision-making approach to better manage transportation investments and serve system-level needs and performance priorities with limited resources. PBPD uses performance evaluations during project development to guide alternative selections and, ultimately, geometric design decisions. During the planning stage, PBPD defines system and project purpose and need, develops concise project objectives from the purpose and need, considers project in the context of the system, and addresses all users. PBPD is based on quantitative analysis for system performance, operations, or safety, and allows for flexibility in design while still meeting project objectives. During preliminary engineering and design, PBPD develops solutions that meet the purpose and need and evaluates tradeoffs based on objective analysis of data. PBPD analysis includes a cost-benefit analysis.

Table 1-2

shows operational and safety tools that incorporate PBPD. When used in planning and design, these tools can be used to compare and select alternative designs based on the operations and/or the number of predicted crashes for each alternative. Costs include cost of constructing or implementing improvements and cost of maintenance. Benefits are calculated in terms of delay savings and crash reduction savings.
