| 4 | Estimation of Traffic Demand at Freeway Work Zones显示文摘An iterative process,combining a macroscopic simulator and a set of the traffic demand-change estimation models,is developed to estimate the traffic demand at work zones in urban freeway corridors.The process is designed to capture the interaction between work-zone conditions and traffic diversion in determining the traffic demand approaching the entrance and exit ramps at a given work zone.The proposed models and process were calibrated and tested with the field data from the work zones in the Minnesota metro-freeway network.The test results indicate promising possibilities of the proposed process in terms of the estimation accuracy and transferability of the demand-change estimation models developed in this study. | Eil Kwon Chongmyung Park | 2021 | Journal of Traffic and Transportation Engineering2021，9，1： | 0 |
