Bridge Damage Review?Loma Prieta Earthquake
The Loma Prieta Earthquake that struck the San Francisco Bay Area on October 17, 1989 caused varying degrees of damage on highway bridges. Within a few hours of the event CALTRANS had...

Lessons Not Learned from the Catastrophic Collapse of Highway Structures in the 1989 Loma Prieta Earthquake
Most of the damage sustained from the 1989 Loma Prieta Earthquake in Northern California was not a surprise to civil engineers and knowledgeable building officials. As early as the 1900s,...

Lateral Load Test on Driven Pile Footings
The October 17, 1989 Loma Prieta earthquake provided an ideal time and situation to perform for the first time, at no installation cost, a full scale lateral load test on a group of driven...

Measuring Section-Related Traffic Data by Correlation Methods?A New Approach to Traffic Monitoring and Control
Traffic monitoring and control systems require reliable realtime data on traffic flow for an efficient performance. A new 'class' of data, the so-called section-related data such as journey...

Automatic Vehicle Classification System

Evaluation of Reliability of Road Network for Better Performance, Advanced Management and Future Network Design
This paper proposes reliability as a new indicator for advanced management and future construction of road networks; and also presents a new reliability analysis method. This article contains...

Public Agency Issues in the Implementation of IVHS
Public agencies will be extensively involved in the deployment, maintenance, and operation of IVHS infrastructure. The existing fragmentation of transportation responsibilities will require...

Automatic Object Identification in Road
The methodology for automatic object recognition in real road traffic environment is presented. The proposed data acquisition methods have been tested on site. In addition, the fundamental...

An Analytical Framework for Minimizing Freeway Incident Response Time
The reduction in incident delay is an important aspect of any freeway management program as it results in substantial savings to roadway users. This paper presents an integrated decision...

A Fleet Management System for Road Transportation
In this paper, an architecture for a fleet management system for road transportation companies is being proposed. This fleet management system integrates planning support with mobile communications...

Optimal Ramp-Metering Control for Freeway Corridors
The paper discusses an optimal ramp-metering control model wherein a corridor is discretized into small road sections, with density as the state variable and ramp metering rates, the control...
