The PDP manual and associated tools provide guidelines to identify activities required during each phase of project development. This manual and the corresponding PDP working site do not represent a 100% step-by-step linear process, but rather guidance and best practices to assist everyone involved in a transportation project.
We are a large, diverse state with a variety of geographic terrains and varying degrees of need. Adding a turning lane on a rural two-lane road to enhance safety for a small village of drivers is as important as adding a lane to an interstate through a major metropolitan area carrying 60% of the northeast's traveling public. From walking paths to major highway redesign, all transportation projects adhere to guidance found in the PDP Manual.
