As urban road networks experience increasing demand, it is not always feasible to expand them physically. To efficiently use the available space, we need to find solutions that do not require physical expansion. Modifying design factors such as driveway access points, medians, and right turn on red control types are among the solutions that are comparatively easy and quick to implement, do not require more land, and can have a significant impact on traffic flow. This study investigates the impact of several design factors on the number of lane changes on urban arterials near freeway interchanges. While lane changing has a significant impact on traffic flow and safety, it has not received adequate research attention since lane changing maneuvers are difficult to measure. Moreover, existing lane changing research is mainly focused on freeways and highways. This study is focused on urban arterials just downstream and upstream of freeway exits and entry points near diamond interchanges, but the methodology and findings can be applied to arterials near other intersection types. The results show that driveway options, median options, and the location of the right turning bays significantly impact lane changes on urban roads near freeway interchanges. The purpose of this study is to prove that low-cost design modifications can impact lane changes, which ultimately impact the operational performance of roadways.
