Travel Times on Changeable Message Signs: Pilot Project

In this report, the author describes the implementation of an automated changeable message sign (CMS) service in California. The object is to display predicted travel times from the message sign to several destinations along the route. A computer program is used to process real time data from loop detectors and calculate the predicted travel times. The predictions are then sent to a Traffic Management Center (TMC) where another program displays them onto the message signs.
