Traffic simulation programs are frequently used worldwide as a tool for analyzing transportation problems with minimum cost. The calibration of a simulation model is the main step for obtaining any representative results from the analysis. It is also an essential step towards obtaining smart solutions for traffic issues in the modern world. It can be used to test and verify the viability of innovative solutions for traffic congestions, accidents and many other related problems. Therefore, main objective of this study was to calibrate a microscopic simulation model using PTV VISSIM for Bahrain. Afterwards, a validation process was performed by comparing the simulation results with the real traffic data. The study location was in Avenue 27, Saar, Kingdom of Bahrain. Two, out of several intersections on this road, were examined in this study. A dynamic simulation was performed on avenue 27 using VISSIM software. Default values from VISSIM were tested for accuracy in terms of replicating real field data including; average travel time and average travel speed. The results with these values showed no significant discrepancy between the model simulation and the field observed values. Simulation model was used to calculate level of service for the study site at present as well as in future. It was found that both intersections were at level of service A, which indicates excellent quality of performance, presently as well as in future. Hence, modifications such as introducing a signal are not required soon. © 2018 Institution of Engineering and Technology. All rights reserved.
