The Contribution of Dynamic Route Guidance and Information Systems to More Efficient Traffic Management
The environmental and traffic-related problems expected as a result of the continued increase in motorization require new solutions if our towns and cities are to survive and their attractiveness...

Dynamic Route Guidance?The Drive Project CAR-GOES
The DRIVE project CAR-GOES has studied strategies for integrating road traffic management and central systems for dynamic route guidance and traffic signal control. This paper summarises...

A Low Pass Filter for Incident Detection
A new algorithm for automatic incident detection was developed after observing that existing algorithm performance can improve if detector data are filtered before use. The new algorithm...

A Real-Time Traffic Diversion Model: A Conceptual Approach
The development of a real-time traffic diversion control system for integrated freeway and arterial networks, as part of the most currently envisioned Intelligent Vehicle/Highway System...

Contact-Free IC Cards for New Railway Ticket Systems
Two types of smart cards which can communicate with an automatic gate machine without contact are developed. The first one uses medium wave radio as communication media. The microprocessor...

Measuring Highway Inventory Features Using Stereoscopic Imaging System
The new stereoscopic measurement approach is discussed in this paper. The objective of this paper is not intended to present another new videologging system. Instead, this paper is to...

Academic Research Efforts in the GuideStar IVHS Program
The Minnesota Department of Transportation (Mn/DOT) and University of Minnesota officials, realizing that Minnesota was among the leaders in both research and implementation of advanced...

NOAA Collection and Dissemination of Marine Information
The National Oceanic and Atmospheric Administration's (NOAA) interest in marinas stems from our mandate to foster boating safety through the issuance of marine navigation products and...

The Application of a Structural Analysis Program to Floating Dock and Guide Pile Design
The floating dock systems and guide piles used in marinas are often designed using over simplified analysis techniques. However, if the dock system is flexible or if either the soil conditions...

Economic Considerations of Marina Design
The planning and design of a marina involves decision making to optimize the economic return of the entire project. Decisions relating to land-use, water-use, and construction require...

Physical Model Testing of Barbers Point Harbor and Marina Complex
