Abstract

The main objective of this paper is to estimate and evaluate the effect of motorcycles on signalized intersections. For this, variables that represent the presence of motorcycles in front of the first vehicle in the queue, between vehicles longitudinally, and between vehicles laterally (on virtual lane) were collected. The results showed that the average effect of a motorcycle positioned ahead or between vehicles on the start-up lost time is between 0.3 and 0.7 s. However, there was no evidence that motorcycles on the virtual lane affects the vehicle queue discharge. Regarding the saturation headways, the results indicated that a motorcycle in front of a vehicle increases its discharge headway by 0.7 s, an increase of 30%. A 10% increase in the proportion of motorcycles decreases saturation flow by around 60 veh/h. The passenger car equivalent factor for motorcycle obtained in this study was 0.21, considering only the motorcycles positioned longitudinally between vehicles.
