Erin’s commitment to this project, her vast network of contacts, and her responsiveness provided an environment for success. Thank you, Erin.  \nThank you to Emily Silverson and Andrew Heidtke, who assisted the project team in attending meetings and providing resources and access to information within WisDOT.  \nThank you to the Wisconsin Traffic Management Center and the Wisconsin State Patrol for being very accommodating to our many requests to archive CCTV footage. Thank you to Scott Naumanand Scott Kozlik for archiving footage to hard drives and thank you to Stacey Pierce for coordinating the resources necessary to ensure the requested footage was archived.  \nThank you to Michael Stalter and Dean Beekman for their help in integrating the Bluetooth data collectors into WisDOT’s system and providing technical support, particularly in the first few months of the project.  \nThank you to Russell Lewis for customizing weekly and annual volume outputs from internal WisDOT tools and then for helping the project team and regional work zone engineers learn how to access the outputs.  \nThank you to the WisDOT regional work zone engineers, who were integral in communicating their needs in a work zone model and tool. Their contributions included several collaborative meetingsand multiple reviews of the model, the WEEKLY tool, and the ANNUAL tool. Additionally, their responsiveness in the data collection phase was superb. The work zone engineers continually provided information about their work zone sites and made sure we had contact information for the construction managers.

Through a combination of research, 52 work zone observations at 14 sites throughout the state, collaboration with WisDOT’s regional work zone engineers, and regression modeling analysis, two new tools were developed to predict work zone capacity parameters for weekly and annual scenarios.  \nThe findings of this study showed using Wisconsin-specific work zone data enabled the calibration of HCM 6th Edition’s work zone capacity model with customizations to meet WisDOT’s specific needs. The recommended model includes coefficients for northern versus southern Wisconsin and used a construction intensity coefficient in lieu of the lateral clearance coefficient in the HCM 6th Edition’s model. A queuing estimation methodology was built into the tools utilizing the speed-density relationship of a moving queue.
