摘要：AbstractThis paper documents the study on car-following behaviors under different environmental conditions and with different leading vehicle types on freeway. Unlike previous studies, in which filed data were collected at limited segments or simulation data were used, car-following time series covering large amount of freeway scenarios were extracted from the up-to-date Strategic Highway Research Program (SHRP2) Naturalistic Driving Study (NDS) database. Differences and distributions of following headway and kinetic patterns were compared for different following conditions. New findings were concluded and compared with previous studies. The results can be used as references for microscopic traffic modeling, transportation systems analysis and intelligent/autonomous vehicle design.
