An Analysis of Congestion Patterns on the Tuaran Bypass and Sulaman KKIP Road Networks in Kota Kinabalu, Sabah

Abstract

This study examines the recurring and non-recurring congestion patterns on the Tuaran Bypass and Sulaman KKIP road networks in Kota Kinabalu, Sabah. The research provides valuable insights into the factors contributing to congestion in the area. A quantitative survey research design was used to collect data through an online survey administered between January and February 2023. A survey instrument adapted from relevant literature was used to collect demographic information about respondents and identify patterns of traffic congestion on both road networks. A total of 1,483, completed responses were obtained and analysed using descriptive statistics. The findings indicate that recurring congestion, primarily influenced by poor roadway conditions, lack of lanes, bottlenecks, and inefficient traffic management, accounts for 52.40% of the congestion. Non-recurring congestion, attributed to poor weather conditions, new development projects, festivals, and accidents, contributes to 47.60% of the congestion. The analysis further highlights the most congested roads during peak hours, with the Sulaman > KKIP Sepanggar > UMS route being the most problematic, followed by the Jalan Tuaran Bypass route. These routes experience heavy traffic due to their significance as major arteries connecting key areas, as well as the presence of construction work, narrow road width, and limited public transportation options. Addressing congestion in the Tuaran Bypass and Sulaman KKIP road networks requires prioritizing improvements in roadway conditions, increasing the number of lanes, optimizing traffic management, enhancing signaling systems, and effectively managing weather-related disruptions and new development projects. By implementing targeted strategies, it is possible to alleviate recurring congestion and mitigate non-recurring congestion, ultimately improving traffic flow and mobility in the area.
