• Abstract:
  This project is a follow-up to Florida Department of Transportation (FDOT) research project BD545-61, “Impact of ; Lane Closures on Roadway Capacity” (specifically, Part A: Development of a Two-Lane Work Zone Lane Closure ; Analysis Procedure and Part C: Modeling Diversion Propensity at Work Zones). In this previous project, the primary ; objective was to update the procedure in the Plans Preparation Manual (PPM), Volume 1, Section 10.14.7 (2006), for ; two-lane roadways. Field data collection was not included in the previous project; thus, the results were based strictly ; on simulation data from the FlagSim simulation program. ; The primary objective of this project was to update the two-lane roadway with a lane closure analysis procedure ; developed under the previous project, based on calibrating the FlagSim simulation program to field data. An additional ; aspect of this that was not considered in the BD545-61 project was to account for the effect of grade on the work zone ; performance measures. An additional project objective was to update the RTF estimation method developed under ; the BD545-61 project, as necessary, based on measured traffic demands (before and during) at work zone field sites. ; Field data were collected at three sites and used to calibrate the FlagSim program. FlagSim was then used to ; generate the data used to update the models contained in the analysis procedure developed under the previous project. ; Local area traffic demand data were also used to update the RTF estimation model.
