Overview

This project is a comprehensive simulation of urban traffic conditions in Tallinn, Estonia, using Simulation of Urban Mobility (SUMO). By employing open-source tools like SUMO, traCI, and Apache Airflow, the study seeks to explore and recommend cost-effective solutions for improving urban mobility in Tallinn without major infrastructure investments.

Objectives

Model traffic conditions in Tallinn using real-time and geospatial data from TomTom, OSM, and mobility surveys.
Evaluate the impact of traffic optimization strategies, such as adaptive signaling and route management, on congestion and travel times.
Analyze traffic behavior at critical intersections and congestion hotspots, with a particular focus on areas like Sikupilli, to recommend data-driven improvements.
Propose scalable and sustainable mobility solutions that enhance existing urban transport strategies without significant physical infrastructure expansion.

Installation

To set up and run the project, follow these steps:

Clone the Repository

git clone https://github.com/Ndeta100/Software_development_final_paper_project.git
cd SUMO_WORK

Requirements Ensure you have the following software installed:
- SUMO
- Python 3.x
- Required Python Packages:
```
pip install pandas matplotlib airflow
```

Network Generation Convert OSM data of Tallinn to a SUMO network:

netconvert --osm-files estonia-latest.osm.pbf -o tallinn.net.xml

Route Creation Generate route files based on TomTom data:
```
python parse_tom_tom.py
```
Run the Simulation Use the following command to run the simulation with SUMO:
```
sumo -c tallinn.sumocfg
```

Scenarios

Traffic Scenarios Simulated

Morning Peak (8 AM): Represents traffic during commuting hours.
Evening Peak (6 PM): Models traffic during evening commute times.
Off-Peak (2 AM): Captures traffic flow during low activity periods.
Afternoon Traffic (2 PM): Represents moderate traffic during midday.

Analysis and Results

Travel Time Comparison
- A t-test conducted on travel times from real-world TomTom data vs simulation results showed a significant improvement in travel times with optimized signal timings and route management.
Congestion Hotspots
- The Sikupilli area was identified as a major congestion hotspot. Targeted interventions in this area, including signal adjustments, led to reduced delays and increased average speeds.
Teleportation Events
- Teleportation incidents, where vehicles get "stuck" and are removed, were tracked. These events highlighted critical areas needing improvements in traffic flow.

Future Work

Adaptive Traffic Lights: Implement real-time adaptive traffic signal control.
Autonomous Vehicles: Explore the impact of AVs on urban traffic congestion.
Public Transport Integration: Evaluate the effect of buses and shared mobility on traffic patterns.
