A model analyzing the driver's process of changing from one lane to the adjacent lane is described based on research presented by Levin. The model uses gap acceptance concepts to evaluate the probability of accomplishing a lane change within a certain distance under various traffic conditions. Such a model can be used in determining the effectiveness of the location of freeway directional and information signs. Application of the developed model can be found in reference (6) where the effectiveness of the location of directional signs, spaced as recommended by the Manual on Uniform Traffic Control Devices on a four-lane freeway, was analyzed. For the purpose of this analysis effectiveness was defined as the probability of completing a lane change within a distance determined by the location and size of a sign with respect to an exit ramp, for levels of service B and C.
