Advanced Demand Signals -II scheme

This paper describes the advanced demand signals -II (ADS-II) scheme that can output signal phases based on both pedestrians´ demands and drivers´ demands, and also presents the basic performance evaluation of the ADS-II scheme. Firstly, we propose the ADS-II scheme, which is an improvement of the ADS scheme that controls signals using vehicles´ location information, in order to output signal phases appropriate for demands both of pedestrians and vehicles. Secondly, a constructed pedestrian model is introduced to the conventional microscopic traffic simulator including the ADS scheme for performance evaluations of both pedestrians and vehicles. Finally, in terms of efficiency, basic performance of the ADS-II scheme is compared with that of the best basic coordinated signal control scheme by this simulator and results show that the ADS-II scheme is superior.
