NCHRP project number | $ Funds | NCHRP Project Title | Effective Date | Completion Date | Responsible Agency | Principal Investigator/NCHRP Staff

 Dashed light blue boxes are on-going NCHRP projects that were initiated by the LTPP ETG. Solid light blue boxes are completed projects.

NCHRP project number | $ Funds | NCHRP Project Title | Effective Date | Completion Date | Responsible Agency | Principal Investigator/NCHRP Staff

 Dashed pink boxes are on-going NCHRP projects that were initiated by other agencies or work groups, but are directly associated with LTPP Data Analysis Plan Strategic Objectives and Analysis Outcomes. Solid pink boxes are completed projects.

Problem Statement Number, O_A_n, Proposed problem title Project Duration, Anticipated Funds

 Dashed white boxes are proposed Research Problem Statements that were developed at LTPP Workshops. See Note 1) for an explanation of the Problem Statement Numbering scheme.

FHWA Technical Support Contractor | O_A_n | Project Title | Planned Start Date | Responsible Agency | Principal Investigator/FHWA Staff

 Hashed orange boxes are planned FHWA projects that will be funded using LTPP budgeted funds.

Note:

1) Problem Statements are assigned a 3 character number using the convention ‘ O_A_n’.  ‘O’ is the associated Strategic Objective number (1 through 7); ‘A’ is the associated Analysis Outcome letter (A, B, C etc.) and ‘n’ is an arbitrarily assigned number used for identification purposes.  The number ‘n’ does not imply a sequence in which Problem Statements should be addressed.
