abstract="Precise understanding of the factors affecting the choice of following time headway in staggered car-following conditions is essential on the part of traffic modelers to provide a detailed representation of traffic flow, which has a predominant role in microsimulation model development, safety evaluation, capacity estimation and evaluation of traffic management strategies. Using trajectory data from video recordings, an evaluation of the impact of a number of factors (i.e. road width, centerline separation, lead vehicle type) on the following headway of a driver is undertaken in this study. A seemingly unrelated regression (SUR) model for time headways is also developed to examine the correlation of headways with different determinants and speeds of following vehicles. <br><br>RESULTS of the study suggest that though there is a direct relationship between speed and headway, the extent of off-centeredness between the interacting pair and vehicle type-specific interactions need to be considered to develop mixed-traffic microsimulation models.<p /> <p>Language: en</p>",
