Path-Flow-Based Cross-Resolution Conversions for Simulation Model

Sub-area traffic analysis is one of critically needed capabilities in practical traffic engineering applications. This paper aims to develop a fully automated network conversion and calibration tool to assist engineers easily extract a portion of a macroscopic planning network to construct a consistent sub-area of interest, and then convert it into a detailed model suitable for microscopic simulation. A cross-resolution simulation (CRS) method is adopted in this paper, which allows a rapid extraction of selected sub-areas from a regional planning network with origin-destination (OD) matrix, and a lane-based expansion of the network topology, a consistent regeneration of subarea path flow and link volume. This paper integrates the above-mentioned key modeling components into an open-source package and conducts a case study to demonstrate its effectiveness.
