• 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.
