Overview

In this task, we will implement a traffic simulation system that gathers user input for intersections, traffic lights, and vehicles. We will then create a TrafficSystem object using the collected data and simulate the traffic system for a specified duration.

Gathering User Input

Intersection Input

The first step in creating a traffic simulation system is to gather intersection data from the user. We will use the get_intersection_input function to collect this data.

def get_intersection_input():
    # Get the number of intersections from the user
    num_intersections = int(input("Enter the number of intersections: "))

    # Create a dictionary to store the intersection data
    intersections = {}

    # Loop through each intersection and gather data
    for i in range(num_intersections):
        intersection_name = input(f"Enter the name of intersection {i+1}: ")
        num_traffic_lights = int(input(f"Enter the number of traffic lights at intersection {intersection_name}: "))
        intersections[intersection_name] = {
            "traffic_lights": []
        }

        # Loop through each traffic light and gather data
        for j in range(num_traffic_lights):
            traffic_light_name = input(f"Enter the name of traffic light {j+1} at intersection {intersection_name}: ")
            intersections[intersection_name]["traffic_lights"].append(traffic_light_name)

    return intersections

Traffic Light Input

Next, we will gather traffic light data from the user using the get_traffic_light_input function.

def get_traffic_light_input(intersections):
    # Loop through each intersection and gather traffic light data
    for intersection_name, intersection_data in intersections.items():
        num_traffic_lights = len(intersection_data["traffic_lights"])

        # Loop through each traffic light and gather data
        for i in range(num_traffic_lights):
            traffic_light_name = intersection_data["traffic_lights"][i]
            traffic_light_color = input(f"Enter the color of traffic light {traffic_light_name} at intersection {intersection_name}: ")
            intersection_data["traffic_lights"][i] = {
                "name": traffic_light_name,
                "color": traffic_light_color
            }

    return intersections

Vehicle Input

Finally, we will gather vehicle data from the user using the get_vehicle_input function.

def get_vehicle_input(intersections):
    # Loop through each intersection and gather vehicle data
    for intersection_name, intersection_data in intersections.items():
        num_vehicles = int(input(f"Enter the number of vehicles at intersection {intersection_name}: "))

        # Loop through each vehicle and gather data
        for i in range(num_vehicles):
            vehicle_name = input(f"Enter the name of vehicle {i+1} at intersection {intersection_name}: ")
            vehicle_speed = int(input(f"Enter the speed of vehicle {vehicle_name} at intersection {intersection_name}: "))
            intersection_data["vehicles"] = intersection_data.get("vehicles", [])
            intersection_data["vehicles"].append({
                "name": vehicle_name,
                "speed": vehicle_speed
            })

    return intersections

Creating a Traffic System Object

Now that we have gathered all the necessary data, we can create a TrafficSystem object using the collected intersections, traffic lights, and vehicles.

class TrafficSystem:
    def __init__(self, intersections, traffic_lights, vehicles):
        self.intersections = intersections
        self.traffic_lights = traffic_lights
        self.vehicles = vehicles

    def initialize_traffic_control_service(self):
        # Initialize the traffic control service
        self.traffic_control_service = TrafficControlService(self)

    def simulate(self, duration):
        # Create a simulation engine object
        simulation_engine = SimulationEngine(self, self.traffic_control_service)

        # Simulate the specified duration
        simulation_engine.simulate(duration)

Simulating the Traffic System

Finally, we can simulate the traffic system for a specified duration using the simulate method of the TrafficSystem object.

class SimulationEngine:
    def __init__(self, traffic_system, traffic_control_service):
        self.traffic_system = traffic_system
        self.traffic_control_service = traffic_control_service

    def simulate(self, duration):
        # Simulate the specified duration
        for i in range(duration):
            # Update the traffic control service
            self.traffic_control_service.update()

            # Update the traffic system
            self.traffic_system.update()

            # Print the current state of the traffic system
            print(f"Time: {i+1}")
            print(self.traffic_system.get_state())

Main Function

The main function is the entry point of the program. It gathers user input, creates a TrafficSystem object, and simulates the traffic system for a specified duration.

def main():
    # Gather user input
    intersections = get_intersection_input()
    intersections = get_traffic_light_input(intersections)
    intersections = get_vehicle_input(intersections)

    # Create a TrafficSystem object
    traffic_system = TrafficSystem(intersections, [], [])

    # Initialize the traffic control service
    traffic_system.initialize_traffic_control_service()

    # Prompt the user to enter the duration of the simulation
    duration = int(input("Enter the duration of the simulation: "))

    # Simulate the specified duration
    traffic_system.simulate(duration)

if __name__ == "__main__":
    main()
