Introduction support apparatus of pedestrian-vehicle separated signal control, introduction support method, and non-transitory computer readable medium storing program

An introduction support method executed by a pedestrian-vehicle separated signal control introduction support apparatus including a computer, the method comprising:

• acquiring, based on data captured by at least one sensor, data regarding movements of vehicles and pedestrians within a measurement zone of an intersection that is a candidate for introduction of pedestrian-vehicle separated signal control;
• calculating a first evaluation index indicating a degree to which the movements of the vehicles in the intersection are impeded by the pedestrians based on the acquired data;
• and
• obtaining an evaluation value for evaluating whether or not to introduce the pedestrian-vehicle separated signal control based on the first evaluation index,
• wherein the first evaluation index is calculated based on statistics regarding an amount of a waiting time that vehicles which are about to turn right or left in the intersection have to wait because they are impeded from turning right or left due to the presence of pedestrians entering the intersection in a predetermined period of time, and
• wherein the waiting time includes a waiting time for a vehicle which is about to turn right or left that stops since this vehicle is impeded from turning right or left due to the presence of the pedestrians entering the intersection, and a waiting time for subsequent vehicles traveling straight ahead that are impeded from traveling due to the presence of the stopped vehicle which is about to turn right or left.

A non-transitory computer readable medium storing a program causing a computer to execute processing for:

• acquiring, based on data captured by at least one sensor, data regarding movements of vehicles and pedestrians within a measurement zone of an intersection that is a candidate for introduction of pedestrian-vehicle separated signal control;
• calculating a first evaluation index indicating a degree to which the movements of the vehicles in the intersection are impeded by the pedestrians based on the acquired data;
• and
• obtaining an evaluation value for evaluating whether or not to introduce the pedestrian-vehicle separated signal control based on the first evaluation index,
• wherein the first evaluation index is calculated based on statistics regarding an amount of a waiting time that vehicles which are about to turn right or left in the intersection have to wait because they are impeded from turning right or left due to the presence of pedestrians entering the intersection in a predetermined period of time, and
• wherein the waiting time includes a waiting time for a vehicle which is about to turn right or left that stops since this vehicle is impeded from turning right or left due to the presence of the pedestrians entering the intersection, and a waiting time for subsequent vehicles traveling straight ahead that are impeded from traveling due to the presence of the stopped vehicle which is about to turn right or left.
