Simplified Web-Based Decision Support Method for Traffic Management and Work Zone Analysis

Traffic congestion mitigation is one of the key challenges that transportation planners and operations engineers face when planning for construction and maintenance activities. There is a wide variety of approaches and methods that address work zone impacts, starting with simple equations, over spreadsheets and deterministic methods, to high-level computer simulation software. Some of the widely used tools include CA4PRS, QuickZone, and VISUM. However, every model has its own limitations and assumptions that are dictated by the applied computational technique. These analysis tools may not fully capture the dynamic nature of drivers' responses to traffic management techniques and significant changes in the transportation network. In this case, performing analyses with a Dynamic Traffic Assignment (DTA) engine, or a similar traffic estimation method, may meet this need while providing additional analysis details (e.g. network, path, origin-destination, and link analyses) for local engineers to justify their decisions/actions. At the same time, technical expertise, data management, and software licensing often become significant barriers for incorporating this type of analysis into every-day operations. The primary objective of this research project is to develop a simple, open source Google Maps/Google Earth interface for scenario-based traffic simulation analysis, primarily focused toward work zone analysis. Engineers may use the simplified interface and Spreadsheet methods to prepare different scenarios without interacting with the calibrated model input data, which will be prepared by the local metropolitan planning organization (MPO). Input data will be hosted remotely, and the simulation engine is offered as a web-application/service to simplify data preparation and improve computational efficiency.
