Variable message signs (VMS) are used to provide dynamic information and are currently used to show different speed limits under different conditions. As speed is an important contributor to road accidents, present study focuses on how well traffic advisory information will help drivers to divert from potentially dangerous conditions. Driving simulator experiment in a laboratory setting on 8.5km long simulated Oyamazaki section made easy to examine the effect of VMS and geometry on mean speed and speed deviations. To create a model of mean speed and speed deviation, a system of two equations will be set up where mean speed and speed deviation appear endogenously. To estimate these two structural equations simultaneously best to use three stage least squares (3SLS) method. Analytical results provide discussion on speeds adopted by each subject and detailed interpretation of 3SLS estimations of mean speed and speed deviation with respect to VMS and geometry.
