This article discusses the requirements for developing a mobile model-based bridge lifecycle management system (MMBLMS). This new system should link all the information about the lifecycle stages of a bridge (e.g., design, construction, inspection, and maintenance) to a 4D model of the bridge incorporating different scales of space and time to record events throughout the lifecycle with suitabl...

Ontario’s Ministry of Transportation (MTO) is responsible for the management of approximately 3000 bridges on the provincial highway network. A modern Bridge Management System is an essential tool to aid the Ministry in fulfilling its mandate to provide a safe, economical, and effective road network throughout the province. The Ministry has engaged ITX Stanley, Ltd., to provide this tool, to be...

It is essential to construct structural health monitoring systems for large important bridges. Zhijiang Bridge is a cable-stayed bridge that was built recently over the Hangzhou Qiantang River (the largest river in Zhejiang Province). The length of Zhijiang Bridge is 478 m, which comprises an arched twin-tower space and a twin-cable plane structure. As an example, the present study describes th...

Major network disruptions have significant impacts on local travelers. Understanding the behavioral reactions to such incidents is crucial for traffic management and planning. This study investigates travelers’ reaction to both the collapse and reopening of the I-35W Mississippi River Bridge in Minneapolis, Minnesota. Web-based surveys conducted at residences in several communities across the m...

Due to the growing number of structurally deficient bridges in the United States, methods for determining the structural performance of in-service bridges is vital to the preservation of the nation’s bridge network. By utilizing field testing, the response of the bridge due to a known traffic load can be assessed, and more accurate structural performance can be determined. The objective of this...

This paper presents a systematic approach for bridge maintenance management that combines a stochastic Markovian performance prediction model with a multi-objective optimization procedure to determine the optimal allocation of funds and prioritization of bridges for maintenance, repair and replacement (MR&R). The prioritization of the bridges is based on the satisfaction of several conflicting ...

As part of a study to develop a comprehensive bridge management system for the Indiana Department of Highways (IDOH), a bridge performance prediction model using the Markov chain was developed. The model can be used to predict the percentages of bridges with different condition ratings as well as to develop performance curves of bridges. The Markov chain, a probability-based method, was used in...

As part of an effective bridge management system, sensor networks can provide data to support both inspection and assessment. Wireless sensor networks WSNs have the potential to offer significant advantages over traditional wired monitoring systems in terms of sensor, cabling, and installation costs as well as expandability. However, there are drawbacks with WSNs relating to power, data bandwid...
