Passenger Car Equivalent (Pce) of Through Vehicles at Signalized Intersections in Dhaka Metropolitan City, Bangladesh

Passenger Car Unit Estimation at Signalized Intersection for Non-lane Based Mixed Traffic Using Microscopic Simulation Model

“…From the literature review, it was found that there are various approaches available for estimation of PCU values for mixed traffic conditions such as time headway method (Saha et al, 2009), simulation method (Arasan and Krishnamurthy, 2008), regression method (Adams et al, 2014), optimization method (Radhakrishnan and Mathew, 2011) and other methods (Shalini and Kumar, 2014). Arasan and Vedagiri (2006) estimated the saturation flow based on classified count and studied the effect of width on saturation flow using a simulation model.…”

“…In this method, headways of the vehicles crossing the stop line of the intersection are used to calculate the PCU values. The following condition should be satisfied to calculate the PCU values by the headway ratio method (Saha et al, 2009) h c-x = Average headway of a car followed by a type x vehicle; h x-c = Average headway of a type x vehicle followed by a car; h x-x = Average headway of a type x vehicle followed by a type x vehicle.…”

Delay-based Passenger Car Equivalent at Signalized Intersections in Iran

“…In recent years, there have been several studies on estimating regional values of PCE. The current literature on regional PCE estimation abounds with examples of PCE at midblock locations [6,10,11] and PCE at intersections [12][13][14].…”

“…In 2009, Saha et al investigated the value of PCE for through vehicles according to the traffic conditions of Dhaka [12]. They used a headway ratio method for estimating the PCE for cars, auto-rickshaws, mini-buses, and buses.…”

“…They demonstrated that the PCE currently used in Bangladesh significantly differs from the PCE achieved from their study. They estimated 1.00, 0.86, 1.42, and 2.16 for PCE values of cars, auto-rickshaws, mini-buses, and buses, respectively [12].…”
