Operations Performance Measurement Research
- SHRP 2: Reliability Focus Area
The second Strategic Highway Research Program (SHRP 2) has several ongoing research projects related to understanding improving travel reliability. The most relevant ongoing projects for operations performance measurement include:- Project L01: Identification and Analysis of Best Practices for Improving Travel Time Reliability
- Project L02: Establishing Monitoring Programs for Mobility and Travel Time Reliability
- Project L03: Analytic Procedures for Determining the Impacts of Reliability Improvement Strategies
- Project L06: Institutional Architectures for to Advance Operational Strategies
- Project L07: Identification and Evaluation of the Cost-Effectiveness of Highway Design Features to Reduce Non-Recurrent Congestion
- Project L11: Evaluating Alternative Traffic Operation Strategies
- Project L12: Improving Traffic Incident Scene Management
- NTOC Performance Measures
A 2005 report recommended 11 performance measures. Follow-up pilot testing of performance measures is being conducted (through NCHRP Project 20-7) to determine whether the measures are useful, to further refine their definition, and provide implementation guidance. - Urban Mobility Information, Texas Transportation Institute
