Work zone queue analysis is an important task for safe and efficient operation of traffic through work zones. The goal of this project is to provide training on multiple work zone impact analysis programs to designers, allowing them to more accurately predict the mobility impacts caused by construction projects. The courses will provide hands-on training on basic analytical methods (queue analysis methods) to compute work zone performance measures (WZPM). WZPM include the following factors: capacity, speed, queue length, delay, and users’ costs. The courses will span five modules. Module 1 briefly reviews the necessary background material. It presents basic principles of traffic flow in work zones, transportation management plans, and other topics. Modules 2 through 4 cover three analytical methods and step-by-step procedures for computing WZPM. Module 2 covers spreadsheets such as QDAT and MODOT. Module 3 covers the work zone capacity estimation procedures of the Highway Capacity Manual. Module 4 covers WorkZoneQ-Pro procedures for queue analysis. These modules complement each other, enabling the participants to analyze more complex work zone conditions. Module 5 discusses how to select and use the appropriate methods to evaluate various traffic management strategies in their impacts WZPM. |
