Field measurement of ideal saturation flow rate from the highway capacity manual
… (PENNDOT) District 12-0 uses an ideal saturation flow rate of 1800 pcphgpl, which is less than the default value of 1900 pcphgpl provided by HCM. This is to account for the less aggressive characteristics of the local drivers. The purpose of this study is to field measure a sample of …

Development of a methodology for measuring delay-based passenger car equivalent for heavy vehicles at signalized intersections
… and are mainly focused on adjusting the ideal saturation flow rate. They do not reflect the total effect of heavy vehicles on delay. The constant PCE value, which is independent of traffic volume and percentage of heavy vehicles, is inappropriate in capacity analysis when delay is considered. …

Bluetooth based dynamic critical route volume estimation on signalized arterials
… and modified based on the volume which is generated using existing timing plans in the system. This interdependency between timing plan and volume on the network is a dynamic process and should be captured to obtain actual traffic states in the network. The current practice is to calculate …

Modeling Permissive Left-Turn Gap Acceptance Behavior at Signalized Intersections
… then implemented to estimate stochastic opposed saturation flow rates. Finally, the third approach uses a psycho-physical modeling approach. The physical component captures the vehicle constraints on gap acceptance behavior using vehicle dynamics models while the psychological component models …
