MY INVOLVEMENT

Background

Certain scenarios, events, and technologies elicit unique driver behaviors with significant operational impacts. These events alter driver behavior on a per-vehicle level, therefore microsimulation is well-suited to predict their impacts. Unfortunately, current microsimulation packages do not feature specialized algorithms to accurately reflect the unique driver behavior observable for each scenario (e.g., for connected and automated vehicle (CAV) applications, road weather events, and travel through work zones). This limits the ability of planners and engineers to predict their impacts.

Even with accurate microscopic models, planners and engineers need streamlined and useful methods for analyzing microscopic model output. FHWA provided recommendations on analytical methods in the Traffic Analysis Toolbox. It would be beneficial, however, to automate these methods and incorporate them into a single, user-friendly platform for microsimulation.

Objectives

Building on the applied research and preliminary development from Developing FHWA Work Zone Driver Model Towards Practical Application, this project seeks to enhance the Work Zone Driver Model DLL and Driver Model GUI, improving the capability, functionality, and usability of these tools and pushing them towards deployment. The aim is to develop the FHWA Driver Model Platform as a single, consolidated repository for specialized microscopic models. It is also envisioned to include tools that assist users in model calibration, in-simulation diagnostics, and post-simulation analysis.
