The traffic situation of highway work zone during discrete periods was analyzed. By dispersing the work periods, the relationships between the capacities of work zones and user costs during different … [Read more...] about User Cost Model of Highway Work Zone During Discrete Periods Under Influence of Uncertain Factors

Work Zone Lane Closure Analysis Model
At the Alabama Department of Transportation (ALDOT), the tool used by traffic engineers to predict whether a queue will form at a freeway work zone is the Excel-based "Lane Rental Model" developed at … [Read more...] about Work Zone Lane Closure Analysis Model
Incorporating Work Zone Configuration Factors into Speed-Flow and Capacity Models
This study aims to develop work zone speed-flow and capacity models, which incorporate work zone configuration factors including the number of work zones, geometrical alignment, work zone speed limit, … [Read more...] about Incorporating Work Zone Configuration Factors into Speed-Flow and Capacity Models
New Methodology to Determine Work Zone Capacity Distribution
Since the true value of work zone capacity is difficult to be known with a perfect confidence, work zone capacity should be represented by means of a probability distribution. Therefore, this study … [Read more...] about New Methodology to Determine Work Zone Capacity Distribution
Impact of Shoulder Use and Capacity Reduction Factors on Highway Work Zone Optimization
Highway maintenance, often requiring lane closure, is very expensive in terms of the costs associated with transportation agencies (i.e., work zone setups) and road users (i.e., delay). Longer work … [Read more...] about Impact of Shoulder Use and Capacity Reduction Factors on Highway Work Zone Optimization
Calibration of VISSIM for Freeway Work Zones with Time-Varying Capacity
This paper presents a systematic procedure for calibration of a VISSIM model to replicate time dependent capacity, speed, and queue length for a 2-to-1 freeway work zone. The procedure models time … [Read more...] about Calibration of VISSIM for Freeway Work Zones with Time-Varying Capacity
