The Operations Planning Toolbox (OPT) is a project to develop a user-friendly, well-documented, open-source, multi-modal transportation modeling software for quick quantitative assessment of operational scenarios in terms of mobility and safety, provided as a desktop application, supported by UC Berkeley PATH. This new software, a mesoscopic simulator, will support the fast execution of the analysis of freeway and corridor operations as well as highways and multi-lane road analysis.

OPT is being developed by UC Berkeley PATH in cooperation with Caltrans, who sponsors the project, and System Metrics Group.

• OPT will replace FREQ12.

• OPT will have a clean, accessible, and self-explanatory user interface.

• OPT will provide an easy and efficient way of building and modifying road networks.

• OPT will provide a capability for easy and efficient tuning of simulation parameters (e.g. freeway capacities) according to established criteria.

• OPT will display simulation results as contour or timeseries plots that can be exported to Excel spreadsheets.

OPT will NOT provide:

• 3D animations;

• analysis and control of individual vehicle behavior.

• other specifically microscopic simulation features.
