I. INTRODUCTION
Cities all around the world struggle with the serious problem of urban traffic congestion. It causes longer commutes, more air pollution, and less effective transportation systems overall. Innovative strategies utilizing data-driven methodologies and cutting-edge technologies are needed to address this dilemma. With an emphasis on data collection, 2D map generation, object detection, visualization, and data integration, this project seeks to enhance urban traffic using realtime analysis and artificial intelligence (AI).The 2D map's visual representation of object detections provides an in-depth description of the traffic situation. Authorities and researchers can gain important information about traffic patterns and congested areas by overlaying detected objects on a map. This image helps in understanding pedestrian movement, analyzing traffic flow, and locating densely populated locations. By creating a centralized data pool that enables seamless integration and analysis, it is possible to manage and analyze the obtained data efficiently. Researchers and urban planners may acquire a full dataset for additional analysis, optimization, and decisionmaking by combining the data collected from object detection with other relevant data sources. The project's findings significantly advance both scientific understanding and local urban area optimization. Numerous uses are made possible by the data acquired, including the study of traffic flow, assessment of density, categorization of vehicles, detection of traffic infractions, and identification of traffic events. The initiative offers useful insights to manage urban traffic and improve the overall transportation system by leveraging the power of AI algorithms and real-time data analysis. In order to overcome the difficulties of urban traffic, this datadriven optimization effort makes use of AI and realtime analysis. The project delivers useful insights for scientific study and regional urban area optimization through accurate data gathering, 2D map generation, item detection, visualization, and data integration. The project's results help in the study of traffic patterns and the creation of plans for decongesting traffic and enhancing the effectiveness of transportation. Urban traffic planning has a chance to be revolutionized thanks to the exponential increase in data availability and improvements in AI algorithms. This research uses AI to mine the massive volumes of data gathered from numerous sources, including GPS, cameras, and other sensors, to uncover insightful information. These insights will allow for better knowledge and study of traffic patterns, congested locations, and causes leading to traffic difficulties.
The project starts with data collection, where exact position determination is critical. Accurate and high-resolution position data may be produced using techniques such as multi-GNSS RTK (Real-Time Kinematic). This data forms the basis for later investigations, allowing for the exact mapping of urban road networks and the identification of essential traffic locations.Developing a 2D visualization map is critical for acquiring a thorough picture of traffic patterns and congestion. Authorities and academics may detect high-density regions, traffic bottlenecks, and other critical elements influencing traffic efficiency by showing the collected data on a map. This graphic supports the creation of efficient traffic flow optimization and congestion reduction techniques.
The research utilizes advanced object recognition algorithms to improve the accuracy of traffic analyses. The YOLO method, when paired with 3D segmentation, detects and classifies a wide range of objects, including automobiles, people, and particular vehicle types (e.g., minibusses and taxis). The project can better evaluate traffic patterns, predict traffic volumes, and comprehend interactions between diverse road users by precisely recognizing and tracking these items.Visualization is critical in making sense of the acquired data. Authorities and academics can acquire significant insights into the spatial distribution of traffic and possible congestion hotspots by overlaying item detections on the 2D map. This visualization supports traffic management and infrastructure development decision-making processes.
In addition, data integration is essential for gaining a comprehensive picture of urban traffic dynamics. A complete data repository is created by combining data from several sources, such as item detections, GPS data, and other pertinent information. This integrated data enables more indepth analysis, allowing academics and urban planners to find complicated correlations, get significant insights, and design successful traffic optimization plans.
The project's findings have the potential to further scientific study on urban traffic optimization and help in local urban area planning. The datadriven strategy, combined with artificial intelligence tools and real-time analysis, provides a formidable foundation for tackling traffic congestion and boosting transportation efficiency.

A control algorithm for signal traffic optimization inside an urban traffic framework is proposed by Sadiqa and Yung-Cheol [17] in a different setting.

Data gathering and accurate location determination.
Getting the information needed to optimize traffic is the first step. Getting photos or videos of the target location is necessary for this. Using kinematic (RTK) technology, precise position coordinates are obtained to guarantee accurate location information Real-Time Kinematic, or RTK, is a positioning method used in surveying, mapping, and navigation applications to produce extremely exact and accurate location coordinates. It is frequently employed in circumstances where centimeter-level accuracy is necessary, such as in land surveying, precision farming, and self-driving car navigation.
A base station and a rover receiver are used in RTK. The base station is installed at an established reference site with established coordinates. Global Navigation Satellite Systems (GNSS), including GPS, GLONASS, and Galileo, send signals to it continuously. The phase and timing of these signals are carefully measured by the base station.
The same GNSS satellites also provide signals to the rover receiver, which is situated at the required location. However, a number of error factors, like air delays and satellite clock problems, have an impact on the measurements made by the rover receiver.The base station instantly provides correction data to the rover in order to correct its position. The discrepancies between the measurements taken by the base station make up this corrective data.

The algorithm has been trained to recognize and categorize various items, including cars, pedestrians, and particular car models (such as minibusses, taxis, bicycles, etc.). In order for the algorithm to effectively learn and detect these items, it must be fed with a sizable dataset of annotated photos or videos during the training process.

D. Visualization and Data Integration
After training the YOLO algorithm, the next step is to display the results on the B-2D map. The identified objects, like cars and pedestrians, are shown and superimposed on the map. This perception gives a reasonable portrayal of the traffic situation nearby.
