The Project

This project focuses on simulating and analysing traffic flow at the Bandon Road Roundabout in Cork, with the aim of identifying congestion patterns and reducing driver waiting times. The roundabout is modelled using SUMO (Simulation Of Urban MObility), with real world traffic demand data sourced from the Transport Infrastructure Ireland data portal. Key performance indicators such as travel time, delay, and waiting time are used to evaluate traffic conditions and show congestion under different scenarios.

The Aim

The overall goal is to reduce waiting times and improve traffic flow through the intersection. To achieve this, three traffic signal control approaches are evaluated: a fixed time sequence, an actuated system, and a genetic algorithm optimised to reduce waiting times by exploiting the roundabout's shape and structure. Each strategy is assessed using the simulation results, allowing comparison on their effectiveness. The findings aim to demonstrate how intelligent traffic control can enhance efficiency at complex urban junctions, and influence future transport planning decisions.
