Civil Engineer | Traffic Performance Analysis & Optimization | Passionate About Improving Transportation Systems and Urban Mobility
🛣️ Excited to share insights from my recent project for the Department of Roads, working under the guidance of Prof. Dr. Pradip Kumar Shrestha! We conducted a comprehensive traffic analysis focusing on optimizing the Sanga underpass on Araniko Highway on Dhulikhel-Suryabinayak section and evaluating scenarios for future traffic demands. Analysis: Using an advanced simulation model from SIDRA Intersection, we assessed traffic flow and performance metrics for three cases: current conditions, lane expansion, and underpass implementation. 1. Current Conditions: - The current traffic conditions exhibit poor Levels of Service (LOS), with ratings of C, F, and E for the West, North, and East approaches respectively. - High delays, long queues, and high Degrees of Saturation (DOS) indicate significant congestion and inefficiency in the existing road network. 2. Lane Expansion: - Expanding from 2 lanes to 6 lanes on the East-West approach, while maintaining the North approach, greatly improves traffic conditions. - LOS improves to B, B, and A for the West, North, and East approaches, respectively. Other Measures of Effectiveness (MOEs) show significant improvement: -Delay decreases by 87%. -Queue length decreases by 94%. -DOS decreases by 73%. 3. Underpass Implementation: -Implementing an underpass for the East-West approach (with 3 lanes for one-directional traffic towards Dhulikhel) results in further substantial improvements: - Delay is reduced by 83%. - Queue length is reduced by 94% compared to the lane expansion case. The underpass allows for smoother flow without interference from the North approach, offering a more efficient long-term solution. 4. Future Traffic Projections: - The 10-year traffic projections indicate that lane expansion can manage the expected increase in traffic volume within acceptable levels. - However, the 20-year projections reveal that the lane expansion may not suffice, with significant delays, queues, and DOS expected to increase again. - In contrast, the underpass remains highly effective for the 20-year projection, providing a 95% reduction in delay, nearly eliminating queues, and reducing DOS by 35%. The analysis underscores the importance of proactive infrastructure planning to address future traffic demands. While lane expansion offers short to medium-term relief, the implementation of an underpass provides a robust, long-term solution, especially for the projected traffic volumes in 20 years. This strategic approach not only enhances current traffic flow but also ensures sustainable and efficient transportation infrastructure for the future. Strategic infrastructure investments like these are crucial for sustaining smooth traffic flows amidst growing urbanization. #TrafficAnalysis #InfrastructurePlanning #UrbanDevelopment #CivilEngineering #TransportationEngineering Let's continue to innovate and optimize our transportation networks for safer, more efficient cities! 🚗💡
