Abstract:Advanced Traveler Information Systems (ATIS) have experienced significant growth since their initial inception in the 1990s. Technologies have continued to evolve at a rapid pace, enabling the integration of advanced solutions for traveler information purposes. As a result of the rapid evolution of technologies and tools available, the Federal Highway Administration (FHWA) has initiated new technical initiatives to investigate, plan, develop, design and implement 'Next Generation' or ATIS 2.0 solutions. This includes the investigation and design of new systems suitable for the collection and aggregation of traveler intent data from trip and route planning apps for use by system managers. This report focuses on analysis of INRIX trip intent data for the test phase of the project. A modeling approach is illustrated, which helped to identify issues in the INRIX intent trip archive data. The available archived INRIX intent data was found to be insufficient (too low of a market penetration of INRIX app users) to support the development of a valid and reliable short-term traffic prediction model. Suggestions and recommendations for future analysis and development efforts are provided.
