1 VISSIM roundabout models have been widely applied in practice to facilitate analyzing the 2 operational performance of roundabouts. To prepare a VISSIM roundabout model for analysis, 3 an essential prerequisite is to calibrate the model by adjusting parameters until real-world 4 roundabout operations are reproduced in the simulation model. Previous calibration research has 5 used qualitative ...

Genetic algorithm is used to calibrate four driving behavior parameters and a set of calibration procedure is put forward based on VISSIM. Using the approach maximum queue length and travel time as the evaluation indexes and applying the calibration method to a single signalized intersection of Yizhuang Zone in Beijing, which validates the effectiveness and practicability of the genetic algorit...

In the application of microscopic simulation models, the importance of model calibration and validation cannot be overemphasized. A recent study proposed a systematic approach of conducting simulation model calibration and validation procedure on the basis of experimental design and optimization, and applied it to an isolated intersection using a VISSIM simulation model. This study further eval...

Transit usage is based on reliable and timely service. Priority is one method for maintaining reduced transit travel times and a reliable schedule, which make transit more attractive. However, with most buses operating within the same traffic lanes as other vehicle traffic, priority policy affects the surrounding traffic. Consequently, priority is often limited to minimal green time extensions ...

SimTraffic and VISSIM are two microscopic traffic simulation tools that are capable of modeling arterial roads with signalized intersections and roundabouts. This study compares the performance of the two simulation tools in modeling dual lane and triple lane roundabouts under different scenarios such as traffic volume, proportion of left turning movement, and proportion of trucks in the traffi...

As transportation systems have become more complex and frequently congested, simulation modeling has gained recognition as an effective approach for quantifying traffic operations. Traffic simulation packages like CORSIM and VISSIM can address these types of network issues, and are frequently used as tools for analyzing traffic. However, there is little information available to the analysts app...

Microscopic traffic simulation software have gained significant popularity and are widely used both in industry and research mainly because of the ability of these tools to reflect the dynamic nature of the transportation system in a stochastic fashion. To better utilize these software, it is necessary to understand the underlying logic and differences between them. A Car-following model is the...
