Modeling the Influence of the Light Rail Transit System on Traffic Operational Performance before and after It Is in Operation
Publication: International Conference on Transportation and Development 2021
ABSTRACT
This research focuses on exploring features in a microscopic traffic simulation software to model and assess the influence of light rail transit (LRT) system before it is built, during the testing phase, and after it is in operation on traffic operational performance measures at intersections. A 2.5-mi urban arterial road in the city of Charlotte, North Carolina, was chosen for modeling and assessment in this research. The selected corridor, along N. Tryon St. from Mallard Creek Church Rd. to University City Blvd., has eight signalized intersections. Vissim traffic simulation software was used to develop simulation models and generate traffic operational performance measures such as vehicle delay, queue length, and level of service (LOS) and examine the influence at selected intersections on the study corridor. The results indicate there is an increase in vehicle delay along minor streets with a decrease in vehicle delay along the major streets parallel to the LRT route after it is in operation.
