Level of service. Traffic simulation. Passing lane.Abstract
The Highway Capacity Manual (HCM-7) is the primary document for analyzing capacity and level of service worldwide. The traffic data used in the development of the manual were obtained on North American roads, so adaptations must be made based on observed local conditions. The present study aimed to adapt the HCM-7 method to estimate the level of service on a Brazilian two-lane highway with passing lanes. The proposed method was based on traffic data produced with the Aimsun Next simulator, previously calibrated from traffic data obtained on a Brazilian highway (BR-040). Based on the simulation results, the coefficients of several equations in the manual were adjusted to assess the service measure Follower Density (FD) values in segments with passing lanes. It was observed that the adaptation of the HCM-7 method provided FD and Level of Service values close to the data found directly in the field.
