At the conclusion of the Second Strategic Highway Research Program (SHRP2) research phase, the SHRP2 Implementation Assistance Program (IAP) was established by the Federal Highway Administration (FHWA) to �help State departments of transportation (DOTs), metropolitan planning organizations (MPOs), and other interested organizations deploy SHRP2 Solutions.� The �SHRP2 Solutions� mentioned in this program mission statement consist of implementable tools in each of the SHRP2 focus areas, namely Reliability, Capacity, Safety, and Renewal. As is clear from the project title, the pilot study detailed in this project authorization document involves reliability data and analysis tools.
Prior to and concurrent with the SHRP2 research phase, the North Carolina Department of Transportation (NCDOT) has been actively and continually engaged in direct support for complementary research in the domain of mobility and reliability. Key NCDOT-sponsored research projects in this effort include completed projects RP 2006-13 Effectiveness of Traveler Information Tools; HWY 2009-05 Assessing Operational, Pricing, and Intelligent Transportation System Strategies for the I-40 Corridor Using DYNASMART-P; and RP 2011-07 Mobility and Reliability Performance Measurement and the ongoing project RP 2013-08 Smartlink � Baseline for Measurement of Benefits. Engagement in these research efforts has put NCDOT in a strong position to lead the way in implementing.
Bolstered by this strong position, the NCDOT submitted a proof of concept pilot study application under round 4 of the IAP in the summer of 2014. NCDOT�s application was approved for FHWA implementation assistance funding, and the statement of work included in this project authorization document outlines the research tasks defined in the IAP application. The proof of concept pilot study envisioned by the application covers all the tools in the Reliability Data and Analysis Tools bundle, namely the implementable research products from the following SHRP2 research projects: L02 Establishing Monitoring Programs for Mobility and Travel Time Reliability; L05 Incorporating Reliability Performance Measures into the Transportation Planning and Programming Processes; L07 Evaluation of Cost-Effectiveness of Highway Design Features; L08 Incorporation of Travel Time Reliability into the Highway Capacity Manual; and C11 Development of Improved Economic Analysis Tools Based on Recommendations from Project C03 [Interactions between Transportation Capacity, Economic Systems, and Land Use merged with Integrating Economic Considerations Project Development].
The SHRP2 data and analysis tools implementation supported by this IAP proof of concept pilot study is fully consistent with NCDOT initiatives aimed at providing enhanced system performance monitoring and measurement. These monitoring and measurement capabilities are essential to enabling performance-based decision support and the assessment of the impact of strategic transportation investments. The results, findings, and recommendations arising from this pilot study will help refine that application of the SHRP2 reliability data and analysis tools, solidify NCDOT�s leadership position in this emerging area, and disseminate lessons learned to the national transportation management community. |
