| 520 | _aThe increasing construction activities on aging and overcrowded roadways in Thailand have raised concerns regarding the high risk of crashes in work zones. Access and egress management, particularly at points where construction vehicles merge or exit traffic streams, contribute significantly to these crashes. The construction on Rama {u2161} road (Highway 35) in Thailand has experienced a significant number of crashes within its long term construction zone. This study aims to propose potential design practices for work zone access and egress points to address the issue of rear-end crashes in work zones. The proposed solutions presented in this study will be tailored to different road geometries.However, the fundamental concept remains consistent: redesigning the work zone layout and traffic lanes to optimize the utilization of adjusted lane widths for an acceleration lane.The impact of these practices on safety measurements (number of conflicts) and traffic measurements (speed and delay) was evaluated using a microscopic traffic simulation model in VISSIM. The results of the evaluation demonstrated that the solution that focused on optimizing the work zone layout to maximize available space for vehicle acceleration showed the most significant reduction in rear-end crashes. All of the proposed solutions demonstrated positive results in terms of reducing and preventing rear-end crashes.Furthermore, the study suggests additional considerations for work zone design, including setting appropriate speed limits, determining the length of placing advance warning signs, and ensuring sufficient lengths for work zone access and egress points (such as acceleration work zone vehicle lane length and merging length). | ||
