I35W Design-Build Its Elements For 2010 Annual Meeting
On August 1, 2007 the I-35W/St. Anthony Falls Bridge collapsed into the Mississippi River
during the PM rush hour, severing a heavily-used commuter and commercial principle arterial
section of roadway serving the Minneapolis-St. Paul metropolitan area. Prior to the collapse,
the bridge served 140,000 ADT, 5,700 of which were estimated as commercial trips.
Surrounding roadways in the metropolitan area system experienced a high level of increased
congestion immediately, as travelers sought alternate routes predominantly during peak
periods but also faced significant detours in accessing the downtown Minneapolis and
University of Minnesota campus areas. This severe impact on the regional transportation
network required an immediate response and solution, requiring the Minnesota Department of
Transportation (Mn/DOT) to expedite the process of replacing the collapsed bridge.

Illinois Tollway Weigh In Motion Enforcement Program
The Illinois Tollway has begun implementing a program of weigh-in-motion (WIM) systems to protect the recent $6.3B investment in congestion relief, open road tolling, widening, and reconstruction of the entire system. Historically, the Illinois Tollway has relied on portable scales and occasional enforcement details at Barrier Toll Plazas to monitor the weights of vehicles on the system. With the application of WIM at select locations, the Illinois Tollway now has both better enforcement and a better idea of exactly what trucks do weigh and their impact on the pavement. This allows the Illinois Tollway to target enforcement where it is most needed and better recover revenue from trucks that are impacting system infrastructure the most, as well as gather detailed load data on the critical pavement infrastructure.

Evaluation of ACS Lite Adaptive Control using Sensys Arterial Travel Time Data
This paper describes the deployment of an ACS Lite adaptive control system on an arterial in Atlanta, Georgia, and presents a performance evaluation including arterial travel time measures obtained using a new vehicle re-identification Sensys Arterial Travel Time System produced by Sensys Networks Inc.. The results of this study show that the deployed ACS Lite system substantially reduced arterial travel time and side-street queue lengths during peak traffic flow periods. This in turn improves system efficiency, thereby reducing vehicle emissions and fuel consumption.

Applying Easy-To-Drive Road Rankings To Routing On Car Navigation Systems And The Web
The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) is developing “Easy-to-
Drive Road Maps” of Japan focusing on how easy a road is to drive on, a specification
determined by the number of lanes, presence/absence of sidewalks, and other road structure
characteristics, in order to make driving more pleasant and reduce traffic accidents. The maps
are currently available only on paper, but in accordance with the developments and
improvements of car routing tools, it is expected that these maps will be applied to car
navigation systems and Web-based route guidance services. To achieve this goal, the National
Institute for Land and Infrastructure Management (NILIM) of MLIT has been moving
forward with a joint research project between public and private sectors on the “Application
of Easy-to-Drive Road Maps to Car Navigation Systems” since its launch in December 2006.
This paper presents i) the results of surveys on expectations of car drivers with respect to the
application of Easy-to-Drive Road Maps in car navigation systems, ii) initiatives put in place
within the framework of the joint public-private research, and iii) a newly- introduced Web-
based route guidance service.

Introduction Of Global Etc: The ETC Solution For Emerging Asian Nations
Highway Industry Development Organization (HIDO) has developed the concept and specification of Global ETC. Global ETC is the ETC system specifically designed to suite emerging Asian nation’s requirements. This paper describes the characteristics of Global ETC that are 5.8GHz Active DSRC based system and two-piece type OBU with smart card, such as flexibility toward multi-applications, especially multi-lane free flow application for Electronic Road Pricing (ERP). Then, it describe general system requirement for Global ETC, and detailed specification of Global ETC on-board unit. Finally, the target price of Global ETC OBU is briefly described.
