+## Introduction
+
+CARLA (Car Learning to Act) is an open-source simulator for testing self-driving systems. It includes traffic rules, allowing flexible testing of driving behaviors without strict adherence to specific laws of any country.
+
+## Key Traffic Principles and Complex Interactions
+
+- **Traffic Signals**: Vehicles must stop at red lights and go on green.
+
+- **Stop Signs**: Vehicles must stop at stop signs and yield to pedestrians 
+  and other cars.
+
+- **Lane Management**: Cars should remain in their designated lanes.
+
+- **Speed Limits**: Different speed limits in various areas of the map allow 
+  testing of speed control and adherence to traffic laws.
+
+- **Pedestrian Rights**: Vehicles must yield to pedestrians at crosswalks, 
+  which is vital for pedestrian detection and ensuring safe stops.
+
+- **Intersection Management**: Vehicles must navigate intersections 
+  effectively, managing stop lights and stop signs while yielding when 
+  necessary to keep traffic moving.
+
+- **Roundabout Navigation**: Vehicles should yield to cars already in the 
+  roundabout. This tests their ability to navigate circular roads and merge 
+  correctly.
+
+- **Crosswalk Behavior**: Vehicles need to detect and stop for pedestrians 
+  at crosswalks, highlighting the importance of pedestrian safety.
+
+- **Bicycle Lane Navigation**: Vehicles should be able to detect and safely 
+  navigate around cyclists in traffic.
+
+- **Parking Maneuvers**: Vehicles are tested on their ability to park in 
+  tight spaces, simulating real-life parking challenges.
+
+## CARLA Maps and Their Traffic Scenarios
+
+CARLA has 12 maps, each designed to test different aspects of self-driving, from basic navigation to complex urban and rural situations. Users can also create custom maps, allowing for additional testing scenarios tailored to specific needs.
+
+### Overview of CARLA Maps
+
+- **Town 1**: A small town with T-junctions and bridges, focusing on managing 
+  intersections and staying in lanes.
+
+- **Town 2**: Similar to Town 1, this town includes shops and homes, testing 
+  navigation and awareness of the surroundings.
+
+- **Town 3**: A larger city area with roundabouts and underpasses, assessing 
+  navigation in roundabouts and speed adjustments.
+
+- **Town 4**: A small town with a figure-eight road, testing navigation in 
+  multiple lanes and interactions with pedestrians.
+
+- **Town 5**: An urban area with multilane roads and a highway, focusing on 
+  highway driving and commercial strategies.
+
+- **Town 6**: A less populated town with unique junctions, testing navigation 
+  in multiple lanes and the use of slip roads.
+
+- **Town 7**: A rural community with no marked roads, which tests navigation 
+  and parking in residential areas.
+
+- **Town 8 & Town 9**: Hidden maps used for the Leaderboard challenge.
+
+- **Town 10**: An inner-city area with various junctions and pedestrian 
+  activity, testing skills in complex traffic situations.
+
+- **Town 11**: A basic map for testing navigation in open areas with fewer 
+  visual guides.
+
+- **Town 12**: A large map based on Amarillo, Texas, featuring urban, 
+  residential, and rural areas to test navigation and visual skills across 
+  diverse environments.
+
+### Rural and Highway Scenarios
+
+Maps like **Town 7** and **Town 12** focus on rural and highway driving, 
+simulating open and high-speed areas. They test long-distance driving, 
+speed management, and safe overtaking, requiring drivers to adapt to 
+unmarked roads and agricultural settings.
+
+## Road Network Creation with ASAM OpenDRIVE®
+
+Road networks in CARLA are built using **ASAM OpenDRIVE®**, which standardizes 
+road descriptions:
+
+- **Hierarchical Structure**: Roads are organized into nodes for better 
+  integration.
+
+- **Reference Line**: Each road has a reference line that defines its shape.
+
+- **Interconnectivity**: Roads can connect to each other for realistic 
+  traffic flow.
+
+## Units of Measurement
+
+To keep tests consistent, CARLA uses standardized units:
+
+- **Speed**: Measured in meters per second (m/s).
+
+- **Distance**: Measured in meters.
