DFROUTER—Estimation of Vehicle Routes from Cross-Section Measurements

Abstract

This contribution evaluates and improves the open-source “DFROUTER” tool that is contained in the SUMO traffic simulation suite. DFROUTER uses vehicle counts (e.g. from inductive loops) to calculate routes of vehicles through road networks. This approach is designed for highway corridors that are covered with measurement facilities at all entry and exit points. The study analyzes DFROUTER’s current functionality and compares it with other approaches that have a similar purpose. Tests performed using different networks and sensor coverage amounts are presented. Additionally, an extension to the software is presented that completes missing flows, increasing the correctness of the tool’s results.
