The increasing number of trucks traveling on the highway has become a great challenge to the capacity calculation at the approach of highway signalized intersections, because of the interactions among cars, trucks, buses and so on. This study investigated and developed modified heavy-truck adjustment model by considering the effects of vehicle type, vehicle position and lane-changing behaviors at the approach of highway signalized intersections. From observations and model analysis, we can conclude: 1) The effects of heavy-duty truck and combination truck on capacity were underestimated by the current standards; 2) Vehicle position has a substantial influence on the capacity of the approach lanes; 3) Lane changing behaviors cause capacity reduction especially when the forced lane-changing occurs; 4) The impacts of trucks and speed advantage are the key factors to motivate the lane-changing behaviors at approach lane.
