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.

This paper reports on the performance of advanced traveler information systems (ATIS)during the 2002 Salt Lake CityWinter Olympic Games. This was the first Olympics in the United States with an established Intelligent Transportation System (ITS) deployment in full operation, and the Salt Lake City ITS installation was among the most comprehensive in the nation. This paper presents excerpts from a larger study, commissioned by Utah Department of Transportation (UDOT) and the Federal Highway Administration. The purpose of that larger study was to document and assess the performance of the UDOT advanced traffic management system (ATMS) and advanced traveler information system (ATIS) during the Olympic Games. An additional purpose was to document and assess the results of the Travel Demand Management program created and implemented for the Olympic Games. This paper presents some of the traveler information findings from that larger study, specifically regarding the CommuterLink Website and the 5-1-1 Telephone Service.

Minnesota is one of eight states combining efforts to design, develop and implement 511 using the Condition Acquisition and Reporting System (CARS) as its foundation. Design of the CARS-511 system began in January 2002. Development took place over the next severalmonths and 511 was fully launched in Minnesota on July 1, 2002. Minnesota’s launch also included a new web site – 511mn.org – and consisted of a statewide promotional campaign designed to increase awareness and use of traveler information. Public response has been overwhelming with daily call volumes up to ten times greater than those received with the previous 10-digit toll free road condition number. This paper shares the lessons learned through design and development, implementation, and preliminary evaluation of 511 in Minnesota.

The objective of this paper is to define a performance measure(s) that can be used to show congestion levels on critical corridors throughout Virginia and develop a general methodology to select and calculate performance measures in order to quantify congestion in a transportation system. These measures can be interpreted to provide benchmarks or base values of congestion to provide a means for measuring change in the performance of the highway system.

This white paper, DMS Message Effectiveness Tool—Signs of Intelligence for Successful Communities, offers practical advice, case studies, and the Skyline Products DMS Message Effectiveness Tool to help agencies develop their policies regarding effective Dynamic Message Sign (DMS) usage. A key to effective advisories is displaying messages that are clear, concise, credible, and actionable—such advisories help the agency achieve the greatest results for its Intelligent Transportation System (ITS)environment.

Specifically, the goal of this white paper is to be a reference tool for any DOT agency developing or tuning its policy on the use of DMS messages. Such a policy would provide guidelines for DMS managers and operators to relay clear, informative, and relevant messages. This is an important consideration, since motorists must be able to quickly comprehend the DMS advisory, filter the information as it relates to their situation, and take appropriate action. Of course, this all happens in a matter of seconds, while drivers speed along in complex traffic conditions and often in less-than-ideal weather conditions.
