| 摘要： | TravTek represents the first major operational test of an Advanced Traveler Information System (ATIS). The operational test was designed to answer a wide range of questions regarding the deployment and use of Intelligent Transportation Systems (ITS) technologies and services. The TravTek system represents a distributed architecture where the ATIS vehicles planned routes based on real-time traffic information provided by a Traffic Management Center (TMC). The in-vehicle system provided drivers a wealth of travel related information that included a computerized yellow pages linked to the navigation system, navigation information, route guidance information, and incident and congestion information. The TravTek system provided drivers the information in various formats (e.g., map-like display versus simplified turn-by-turn display) and modalities (visual versus auditory). The system with respect to the driver interface and data collection capability was truly designed for conducting field research. One of the major evaluation goals for TravTek, was the examination of the safety impact for a fully matured system. This paper focuses on the methodology and lessons learned from the TravTek safety evaluation. Results of the evaluation are presented to illustrate methodological and analytical issues. |
