Highway capacity through vissim calibrated for mixed traffic conditions

The Driver Behaviour and Impact of Speed on Road Safety on the Motorways in Croatia

“…Moon and Ko (2014) in their paper "Vehicle Speed Measurement using SAD Algorithm" proposed a mechanism by which traffic flow and speed of vehicles on the motorways can be measured by using video cameras to detect traffic [14]. Mehar et al (2014) conducted a research of capacity of four-lane motorway for mixed traffic conditions by VISSIM simulation tool, to check, according to real measuring, the applicability of simulation [15]. The prediction of flow, density and the speed of traffic flow have wide application in many areas, using neural networks, developed by Park et al (2014) in the paper "Intelligent Trip Modelling for the Prediction of an Origin-Destination Travelling Speed Profile" [16].…”

Simulation of Traffic Flow to Analyze Lane Changes on Multi-lane Highways under Non-lane Discipline

“…Linear regression analysis was carried out to propose the relationship between capacity and motorcycle percent share for the highways in both countries. Mehar et al, (2014) determine the capacity of fourlane divided highway under mixed traffic conditions. Authors analyzed field data and suggested the capacity of four-lane divided highway with the paved shoulder as 5227 PCU/hr/dir.…”

“…Capacity obtained from default values of these two parameters may not be reliable unless calibration is performed using field data. The present study refers to the previous simulation study performed by Mehar et al (2014) under mixed traffic on the calibration of VISSIM parameters influencing the capacity of four-lane divided highway. The outcome of the calibration was based on the sensitivity analysis performed by considering multiple parameter analysis.…”

Calibration of Vissim Model for Multilane Highways Using Speed Flow Curves

“…This methodology was also compared with traditional method of calibration and shown that this method performance is better. Mehar et al [9] performed calibration of simulation model and developed speed flow curves for 4-lane divided highway. The speed flow curves from both field data and simulated data were compared.…”

“…The speed flow relationship is drawn for simulated data and is overlapped with the field speed flow curves, significant difference has been noticed.Traffic volume data and Speed data are matching with the simulated data but when compared together, showing variations is shown in Figure 2 and hence calibration is required to match speed flow curve of field and simulated data. Mehar et al [9] suggested that the effect of CC0 and CC1 is more on capacity and is used to calculate safety distance. So, Wiedemann 99 parameters are taken into consideration for the calibration purpose.…”
