• This paper presents the evaluation of work zone capacity in Thailand and the development of closure scheduling tools in order to schedule work zone by minimizing all related traffic impacts. The results of the capacity analysis revealed that the work zone capacities deriving in this study are higher than the work zone capacities suggested by the highway capacity manual, HCM 1994. These capacities are used to develop the closure scheduling tool. The developed tool is computer-based which considers the excessive flows due to lane closure and determine the dissipation period affecting from the closure. The results show the summary of dissipation durations for different closure schedules. To demonstrate the real world application of this developed tool, a selected section of Highway No.1 (Phaholyothin highway) was selected as a case study. Results revealed that the unsuitable closure periods are 6:00 hr. to 8:00 hr. and 16:00 hr. to 18:00 hr.
