Capacity Analysis for Planning of Junctions (CAP-X) Tool User Manual

The Capacity Analysis for Planning of Junctions (CAP-X) Tool is intended to aid in the determination of a preferred alternative for a given intersection project by providing an objective, quantifiable basis to compare the operational performance of different intersection types. This tool may be of use to transportation planners, transportation engineers, and highway and street designers. This document provides information and guidance on how to use the CAP-X Tool, a macro-based, Microsoft Excel spreadsheet, to assess the operational performance of a variety of intersection geometry and control scenarios in terms of volume to capacity ratio and multimodal accommodations.
