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.

Transportation agencies need effective ways to inform the traveling public about current road
conditions and to manage congestion. Travel time systems and variable toll pricing systems
are two proven ways to meet these goals. These two systems require similar data, perform
similar calculations to produce correct results and both need to distribute the final
information to motorists on the roadway. Combining the systems makes sense from
technological and operational perspectives. However such a system must be designed
carefully to manage complexity while maintaining data integrity, performance, and
reliability.

Historically, autonomous vehicles have been predominantly used in military applications.
There are a growing number of indicators, however, that autonomous vehicles may be used
for on-road driving in the future. For a driverless vehicle to safely navigate on the same
roadways as other driverless vehicles as well as human-driven vehicles, its behavior will need
to be generated appropriately and robustly. For an on-road vehicle, these behaviors primarily
focus on navigation. Autonomous vehicle navigation for on-road driving consists of tasks
ranging from steering and speed control to negotiating complex urban environments with stop
signs, traffic lights, other vehicles, and pedestrians. Southwest Research Institute (SwRI®)
has undertaken the Southwest Safe Transport Initiative (SSTI) aimed at investigating the
development and commercialization of vehicle autonomy as well as vehicle-based telemetry
systems to improve safety and facilitate traffic flow. This paper will discuss the modularized
approach used to perform the navigation and path planning tasks for on-road driving that have
been implemented on the SSTI autonomous vehicle. It includes details on the global route
planning, local path planning, speed profile generation, and a short discussion on planning
paths for lane changing and obstacle avoidance.

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.

The OTN Statewide Transit Trip Planning Project in Oregon began as an idea.

This presentation will address how that idea was developed into realistic options for implementing statewide transit trip planning in Oregon.
