8 NCHRP RESEARCH AREAS Topics across the spectrum of highway concerns The subject matter of NCHRP projects extends across the full spectrum of concerns within the highway industry and demonstrates AASHTO’s interest in acquiring answers to the many acute problems facing DOT administrators and engineers. Problems submitted as candidates for funding each year are given a unique identification number based on the NCHRP Classification System. See Exhibit 4. This identification number, correspond- ing to the specific problem area ad- dressed, is part of the number that iden- tifies a research project throughout its life cycle, until the project is given an NCHRP publication number when the final deliverable is published. For ex- ample, NCHRP Project 15-47 identifies a project in Area 15 (General Design). NCHRP Project 19-11 identifies a proj- ect in Area 19 (Finance). Once research was completed, final reports for these projects were published, respectively, as NCHRP Research Report 839: A Per- formance-Based Highway Geometric Design Process and NCHRP Research Report 850: Applying Risk Analysis, Value Engineering, and Other Innova- tive Solutions for Project Delivery. Table 2 of the Annual Report uses this project numbering system to present in- formation about active, completed, and pending NCHRP projects in 2017. The projects are grouped sequentially from Area 1: Design—Pavements through Area 25: Transportation Planning—Im- pact Analysis.

The research results are presented in NCHRP Research Report 839: A Per- formance-Based Highway Geometric Design Process. NCHRP Project 19-11 examined the state of the art in managing project development and delivery, addressed through application of Value Engi- neering—a systematic process that combines creative and analytical tech- niques. Guidance is documented in NCHRP Research Report 850: Applying Risk Analysis, Value Engineering, and Other Innovative Solutions for Project Delivery.
