This report provides a detailed description of the algorithms that will be used to generate harmonized recommended speeds

and queue warning information in the proposed Intelligent Network Flow Optimization (INFLO) prototype. This document

describes the functional requirements, design principles, and constraints controlling the development of enhanced

queue warning and speed harmonization algorithms. Also presented in the report are the processes and

procedures that are used to format and place the data into the INFLO database where it can be accessed by other

components in the prototype. This report also presents the processes and procedures used by the queue warning

algorithms to provide both infrastructure-based and vehicle-based queue warnings, how measured road weather

condition information will be used to generate recommended link travel speeds appropriate for the prevailing

weather conditions, and how harmonized speed recommendations will be derived from infrastructure-based

information. Finally, the report also shows how the prototype will use the information produced by the algorithms to

generate both infrastructure and vehicle-based warning messages.
