Pilot Experiment for Profile Signal Control System

The profile signal control is a new decentralized signal control system that utilizes the vehicle arrival forecast from upstream. The National Police Agency decided to conduct the model deployment initiatives to clarify requirements for nationwide development of this system. Then this signal control method had been evaluated in Kanagawa Pref. and Ehime Pref. in 2006, and Mie Pref. and Miyazaki Pref. in 2007, where signal controllers were controlled by central computers of the traffic control centers. As the next step, the evaluation had to be conducted in the different traffic environment for two years since fiscal year 2008. Then some area in Saku City of Nagano Pref., where signal controllers were controlled locally based on Time-of-day parameters, was chosen as the test bed. The target date of operation start is early in 2009. In this paper, the outline of the system the authors developed for the profile signal control and the simulation evaluation aiming to clarify the basic performance before the experiment is shown.
