This paper describes the full automated advanced demand signals II (FA-ADS-II) scheme and its performance evaluations. Firstly, the FA-ADS-II scheme is proposed. This is scheme that the ADS-II scheme is extended to automatically decide appropriate system parameters' values according to traffic conditions based on estimated costs without any database; The ADS-II scheme is a traffic signal control scheme...
This paper describes improvement of the advanced demand signals II (ADS-II) scheme and performance comparisons between the conventional ADS-II scheme, the improved ADS-II scheme and a basic coordinated control scheme. Firstly priority of long idling users and the control both of the pedestrian red/green right-turn arrow indication and of the pedestrian red/vehicular green indication by using calculated...
This paper describes quantitative evaluation of driving assistance systems that use on-board sensors for getting surrounding vehicle information, and/or inter-vehicle communications for sharing information with other vehicles. The safety performance of each system is quantitatively evaluated with an improved microscopic traffic flow simulator. Simulation results show that the performance of the system...
This paper describes the multi-class zone ITS communication scheme considering real-time and short periodical communications for vehicle safety in intersections. In our proposed scheme, an area near an intersection is categorized into the nearest area and the quasi-nearest area. Vehicles communicate with a base station every 20 ms in the nearest area. In the quasi-nearest area, vehicles communicate...
This paper describes a new multi-hop communication using heavy vehicles for hopping, and including of this proposed scheme to VRCP that is a protocol integrating inter-vehicle and road to vehicle communications for vehicle safety with vehicle information sharing (VIS). The proposed scheme realizes VIS in neighbor vehicles with three hops by hopping heavy vehicles. From the results of simulation, it...
This paper describes construction of the M-CubITS pedestrian WYSIWYAS navigation system both in outdoor and indoor areas, toward realization of the M-CubITS pedestrian WYSIWYAS navigation environment. In outdoor navigation, we construct the experimental Saitama University campus outdoor navigation system "CamNavi" using ordinary mobile phone terminals as users' terminals and the i-application...
