|Abstract:||A computer simulation model was developed to study the consistency between different headway distributions and car-following rules. Test were run at two volumes (400 and 800 vehicles per hour) using the linear, logarithmic, and exponential car-following rules with the shifted negative and composite exponential headway distributions. Data was kept on the headways at entrance, mid-point, and exit. The major conclusions were: 1) higher volumes tend to abandon established headway distributions, 2) longer tracks increase the variance of headways, 3) the linear car-following rule maintains the same headway distribution from entrance to exit, and 4) at 800 vph, the composite exponential headway distribution does not maintain the same distribution with any car-following rule. Based on these conclusions, it is important that researchers employing simulation pay special attention to the consistency between car-following rules and headway distributions. That is, the selection of car-following rule and headway distribution cannot be done independently. Their combined effect must be recognized. Several appendices are also included which contain all variables used, flow charts, program listings, sample runs, sketches, and a summary of statistical results.|
