84 Vol15 = volume of directional traffic during a 15-minute against the mean LOS response for each video clip. The HCM period matched the video clips 15% of the time. The proposed LOS L = total number of through lanes on the approach to models matched the clips between 27% and 46% of the time. the intersection The second model had the highest percentage match because it can predict LOS A and B. The first model is better at pre- dicting the poorer levels of service (E and F) than the second 7.3 Performance of Bicycle model. LOS Model on Video Clips Exhibit 92 compares the ability of the existing HCM speed- based LOS model and the proposed bicycle LOS models
