| Outline of Final Research Achievements |
In order to design signalized intersections, not only the optimization method of signal control parameters, but also settings of variables such as lost time or minimum pedestrian green time which can be constraints of the optimization problem is necessary. The latter is determined by trajectories of road users affected by road geometry and traffic lights and its value affects performance of the intersection. However, existing studies do not fully consider the influence of road geometry upon users’ trajectories.
This study proposed user maneuver models which can represent the impact of geometry, traffic control and reaction to other users. Especially, 1) two-dimensional vehicle maneuver model using jerk minimization principle and 2) sudden speed change model of pedestrians on crosswalks are proposed. Monte-Carlo simulation using these models evaluated clearance time and minimum pedestrian green time considering conflict risks between road users.
