A Comparison of Capacity Estimation Methods for Two-Way Four-Lane Freeway Work Zone Capacity Using Field Data
Work zone environments are complex, and adequate capacity estimation methods must consider more factors than regular freeway sections. In order to avoid the undue influences on the traffic capacity … [Read more...] about A Comparison of Capacity Estimation Methods for Two-Way Four-Lane Freeway Work Zone Capacity Using Field Data

Calibration of Vissim Models for Rural Freeway Lane Closures: Novel Approach to the Modification of Key Parameters
The definition of freeway work zone capacity has been a topic of debate for several decades, leaving agencies with limited guidance on predicting the behavior of traffic flow at given volumes for … [Read more...] about Calibration of Vissim Models for Rural Freeway Lane Closures: Novel Approach to the Modification of Key Parameters
Study on the Capacity of Urban Road Construction Section Under Mixed Traffic Environment
Based on the analysis of the calculation model of the capacity of urban road construction section, a calculation optimization model considering the influence of non-motor vehicle factors on the … [Read more...] about Study on the Capacity of Urban Road Construction Section Under Mixed Traffic Environment
Work Zone Traffic Simulation Using Cellular Automata
The focus of the present work is to develop a simulation model using cellular automata for work zone traffic containing homogeneous traffic condition. Work zone is created by blocking some of the … [Read more...] about Work Zone Traffic Simulation Using Cellular Automata
