Development Of A Route Guidance Generation System For Real-Time Application

. This paper describes the route guidance generation component of DynaMIT, a dynamic traffic assignment (DTA) system intended for deployment in a traffic center and capable of generating real-time prediction-based guidance information. After providing a general overview of the system, the paper discusses the principal theoretical and algorithmic issues which influenced the development of its guidance generation component. Keywords.

INTRODUCTION DynaMIT (Dynamic Network Assignment for the Management of Information to Travelers) is a real time dynamic traffic assignment system that provides traffic predictions and travel guidance. Travel guidance refers to information provided to tripmakers in an attempt to facilitate their decisions relative to departure time, travel mode and route. Clearly, departure time and (to some extent) travel mode information is only effective prior to trip departure, whereas route guidance recommendatio..
