Abstract

The overarching goal of this research project is to enable state DOTs to document and monitor the reliability performance of their highway networks. To this end, a computer tool, TRIC, was developed to produce travel reliability inventories from various traffic data sources. In due course, travel reliability inventories will provide necessary inputs to next-generation transportation decision-making tools that are sensitive to travel reliability. TRIC incorporates reliable routing algorithms to construct and rank travel reliability indexes on routes between any given origin-destination pair in the network. It also implements a basic graphical user interface for creating and visualizing travel reliability indexes and archiving them in ESRI shape format, which can be read by most GIS (geographic information system) software. Case studies using data from the Chicago area were conducted demonstration purposes.
