| Outline of Final Research Achievements |
The system providing traffic signal information to a vehicle approaching a signalize intersection has been developed, by which traffic congestion is relieved and an amount of CO2 emissions is also reduced. First, as a pedestrian signal can be regarded as prior information on signal change for a vehicle from green to amber/red, the differences between vehicles approaching an intersection with/without a pedestrian signal were grasped by observing real vehicle movements. Then, based on the observation results, experiments using a driving simulator were conducted and it was clarified that the information provision on traffic signal can smooth traffic flows and also reduce an amount of CO2 emissions form vehicles approaching a signalized intersection. Furthermore, it was found that traffic environment as a road network can be improved by linking the information provision to traffic signal control.
