Urban Traffic Simulation

A realistic simulation of traffic flow in an urban environment using Object-Oriented Programming concepts. The goal is to analyze traffic patterns, congestion points, and the impact of traffic signals on vehicle flow.

Usage of OOP Concepts

1. Classes:

   1. Vehicles
   2. TrafficSignal
   3. Pedestrian
   4. Intersection
   5. Road

2. Objects: To create instances of classes for each vehicle, traffic signal, pedestrian, and the intersection in the simualtion.

3. this pointer: The this pointer can be used to refer to the current instance of a class.

4. Encapsulation: To encapsulate properties and behaviors within their respective classes.

   • Example - Vehicle class encapsulates speed, position, and lane-changing behavior.

5. Abstraction: To define clear interfaces and hide implementation details.

   • Example - TrafficSignal class provides an interface to change signals without exposing internal timer logic.

6. Inheritance: To create a hierarchy of vehicle types (e.g., Car, Bus, Bike) that inherit from a base Vehicle class.

   • Example -
     • class Vehicle { /* base class */ };
     • class Car : public Vehicle { /* derived class */ };

7. Polymorhism: To define a common interface for different vehicle types and traffic signals, allowing for dynamic method invocation.

Features

• Roads and Lanes: Represent roads with multiple lanes and simulate lane-changing behavior.
• Traffic Rules: Enforce traffic rules such as speed limits, stop signs, and right-of-way.
• Congestion Analysis: Monitor and report traffic congestion at different points in the simulation.
• Event Logging: Log events such as accidents, traffic jams, and signal changes for analysis.
