    The research presents a study of operating speed prediction model designed to increase the efficiency and safety of transportation systems. Operating speed is defined as “85th percentile of the distribution of observed speeds used to measure the operating speed associated with a particular location or geometric feature.†Operating speed is an important parameter influencing traffic flow and overall system performance. An operating speed prediction (OSP) model is a tool used in road safety and transportation engineering. The model uses real-time data from various sources and road infrastructure, to find dynamic factors affecting operating speed. Variables, such as spot speed and spatial coordinates, of the vehicles were analyzed. Models were developed to predict the operating speed using spot speed data. R software and Microsoft excel are employed to analyze the complex relationships among multiple variables and predict future operating speeds. The speed data is collected using Laser camera, and geometrics of the road is obtained using Google Earth pro and civil 3D. Data of the model is conducted over a stretch of 10 km on Padubidri to Karkala (SH-01) in Dakshina Kannada district of Karnataka state for 10 curves at these locations. Integrating prediction model into transportation management systems has the capacity to enhance traffic control, and ultimately increase the overall efficiency of transportation networks. The results shows the model's accuracy and robustness in predicting operating speeds for two wheeler and car. This research is helpful for the ongoing efforts to develop transportation systems. This offers a practical tool for planners and engineers to make informed decisions that promote smoother traffic flow, reduce congestion, and enhance road safety. The proposed operating speed prediction model serves as a valuable asset in the quest for sustainable urban mobility solutions. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
