Performance Analysis of 4-legged Intersection Under Heterogeneous Traffic Condition

In the modern era, India is experiencing significant economic development, and the field of traffic engineering plays a crucial role in shaping this progress. As India endeavors to build smart cities, efficient traffic management becomes paramount. The seamless flow of traffic is of utmost importance to ensure optimal functioning within these smart cities. Consequently, the focus of this research paper is to identify and address the challenges present in the traffic systems of Indian cities. Specifically, this study centers around a 4-legged intersection located at Engineering College Chauraha in Lucknow. This intersection holds great significance in Lucknow as it serves as a vital connection between Sitapur and Ayodhya. By examining this particular intersection, we aim to shed light on the issues faced in its traffic system. Data collection involved conducting observations during weekday peak periods from 5:30 pm to 6:30 pm. To classify the traffic accurately, video recordings were utilized, categorizing vehicles into three distinct types: light vehicles, heavy vehicles, and bicycles. The operational performance analysis of the intersections was subsequently carried out using the powerful SIDRA INTERSECTION software. The findings reveal that the intersection is operating close to its maximum capacity, yet it fails to provide an adequate level of service (LOS) considering the high volume of traffic it handles. The analysis of the volume to capacity (v/c) ratio indicates that the intersection is in an unstable state. In summary, the results strongly indicate the necessity for improvements to enhance the intersection’s performance.
