Developed as part of the Phoenix AZTechTM national ITS Model Deployment Initiatives (MDI), twenty-three traveler information kiosks have been operational for more than three years. These kiosks were built as part the regional Advanced Traveler Information System (ATIS) to provide public with useful traveler information, including real-time traffic condition. Recently, an effort was initiated by the Maricopa County Department of Transportation, the lead agency of the AZTechTM program, to examine and assess the traveler information kiosk program in the Phoenix area. This paper summarizes the major findings of the study, including reviews of the procurement and implementation history, basic configuration, operational features, information contents, and usage assessment. Despite the sound design, the average level of usage of the kiosks was found to be less than satisfactory. In addition to the discussions of possible rooms for improvement, a viable alternative to the information kiosks for traveler information dissemination in public locations was also discussed.

Operating agencies and 3rd party wireless service providers in Taiwan, Republic of China (ROC), have been developing a comprehensive traffic information service system covering the urban expressways and arterial transportation facilities. These available traffic information can be used for effective traffic routing and congestion management applications. To support the advanced traveler information service, a "Traffic Data Fusion Process" (TDFP) was developed that is based on both historical and real-time link travel times. This paper describes the design and implementation of automatic computer- assisted procedures or the "Traffic Data Fusion Process," to estimate the updated link-travel-time, select proper incident responses, and construct traffic information messages. The proposed system, currently being developed, can distribute these real-time traffic informations automatically to all users.

The ACAS integration of FCW and ACC stands to have a major influence on the driving process, from the viewpoint of safety, convenience, and traffic flow.

The ACAS FOT will study the naturalistic use of this sophisticated driver assistance technology in diverse traffic and road environments by laypersons.

By means of a massive program of subjective and objective measurements, an authoritative set of results and findings is expected.

Real-time transit passenger information systems are intended to improve the level of service provided by transit agencies. Such systems provide real-time information on when buses on specified routes are expected to arrive to a bus stop. Although such information is assumed to be of benefit, methods for evaluating these benefits under various conditions are limited. This paper expands upon the functionality and application of an evaluation methodology recently developed by the authors. The methodology focuses on the potential benefits of bus arrival information systems to passengers waiting at bus stops under various supply and demand characteristics. Transit bus operations and passenger arrivals are modeled as a stochastic system where the operator uses real-time bus location data to provide to waiting passengers bus arrival time information that maximizes passengers’ utilities. Simulation results reveal the nature of the dependence of the value of such information systems on the type of real-time data available to the operator, bus operations characteristics, and demand patterns. These results indicate that while the first two influence the value of information to passengers, demand patterns do not have a significant impact.
