River Bridges under Design flood level has the possibility of large-scale disaster by bridge buoyancy and reversing on increasing of water level when it is raining. Therefore it is needed to prepare the measure for preventing damage and securing the safety of drivers on the expressway. This technical paper describes general course of production, installation and operation on flood warning equipment using the Mobile System for solving this problem. We installed this unique equipment on the River Bridge on Yeongchon, Gyeongbuk in 2009. Consequently, we have the efficacy on the expressway’s bridge maintenance by the Mobile System, which checks the increasing water level of River Bridge anywhere. In this paper, we will introduce expressway maintenance managers to more efficient maintenance method with this result. Published in 2010 by Korea Expressway Corporation.

Various driver assistance systems have been developed in recent years. Pattern recognition algorithms, using several kinds of sensors mounted on vehicles, have been applied to detect “overt hazards”. We have been trying hard to expand use of these systems to every vehicle on the road in order to reduce the number of traffic accident fatalities. Furthermore, we think that “covert hazards”, which cannot be detected by the existing systems, are more important than “overt hazards” in urban areas. In this paper, we propose a hierarchical architecture for assessing both types of hazard, combining causal knowledge with stochastic collision prediction capability. The knowledge base evaluates “covert hazards”, using expected risk values as temporal and spatial relationships for each object. The collision prediction takes account of “covert hazards” to calculate the expected risk value. This architecture is examined for several typical scenes, such as a vehicle passing alongside parked cars.

The purpose of this paper is to develop a method for estimation of reliable path ­travel time
using data obtained from the toll collection system on expressways. The toll collection system
records departure and arrival time stamps as well as the identification numbers of arrival and
destination tollgates for all the individual vehicles traveling between tollgates on expressways.
Two major issues reduce accuracy when estimating path­ travel time between an origin and
destination tollgate using transaction data collected by the toll collection system.

The North/West Passage Program is a collaboration of eight adjacent Northern states
along the I-90/I-94 corridor from Seattle, Washington to Milwaukee, Wisconsin.
These states share a long term vision that travelers will one day receive information
about weather, road construction, and major incident event summaries for the entire
corridor without the need to check individual state reports. A number of ITS
standards exist for data and information exchange, however the standards allow for
many optional phrases when describing events or conditions. This paper presents an
effort to develop a set of corridor-wide consistent event descriptions that can be used
by each North/West Passage state to describe major events, and ultimately support a
very effective exchange of event descriptions.

The potential to create innovative information services and applications, such as real-time
traveller information for a multi-modal journey for any given destination, or combination of
destinations, has never been greater. A facility or forum that could provide an experimental
environment for developing such services, an "information incubator", could encourage wider
experimentation with data and help persuade the users and owners of information to
collaborate and undertake further innovative projects. Using the scenario of providing realtime
traveller information for a multi-modal journey for a given destination, or combination
of destinations and/or activities, this work aims to demonstrate how a facility or forum could
be developed and provide such an environment. Notably, this work has been successfully
completed within a few months, which in itself is a significant feature of the challenge.
