TRB's second Strategic Highway Research Program (SHRP 2) Report S2-L10-RR-1: Feasibility of Using In-Vehicle Video Data to Explore How to Modify Driver Behavior That Causes Nonrecurring Congestion presents findings on the feasibility of using existing in-vehicle data sets, collected in naturalistic driving settings, to make inferences about the relationship between observed driver behavior and nonrecurring congestion.
The report, a product of the SHRP 2 Reliability focus area, includes guidance on the protocols and procedures for conducting video data reduction analysis.
In addition, the report includes technical guidance on the features, technologies, and complementary data sets that researchers can consider when designing future instrumented in-vehicle data collection studies.
The report also highlights a new modeling approach for travel time reliability performance measurement across a variety of traffic congestion conditions.
