Abstract:Although extensive research has been conducted on urban freeway capacity estimation methods, minimal research has been ; carried out for rural highway sections, especially sections within work zones. This study attempted to fill that void for rural ; highways in Kansas, by estimating capacity of rural highway work zones in Kansas. Six work zone locations were selected for ; data collection and further analysis. An average of six days’ worth of field data was collected, from mid-October 2013 to late ; November 2013, at each of these work zone sites. Two capacity estimation methods were utilized, including the Maximum ; Observed 15-minute Flow Rate Method and the Platooning Method divided into 15-minute intervals. The Maximum Observed ; 15-minute Flow Rate Method provided an average capacity of 1469 passenger cars per hour per lane (pcphpl) with a standard ; deviation of 141 pcphpl, while the Platooning Method provided a maximum average capacity of 1195 pcphpl and a standard ; deviation of 28 pcphpl. Based on observed data and analysis carried out in this study, the suggested maximum capacity can be ; considered as 1500 pcphpl when designing work zones for rural highways in Kansas. This proposed standard value of rural ; highway work zone capacity could be utilized by engineers and planners so that they can effectively mitigate congestion at or ; near work zones that would have otherwise occurred due to construction/maintenance.
