Fatigue Strength of Welded Wire Fabric
Long life fatigue tests were made on 12 concrete slabs reinforced with large diameter, Grade 75, deformed welded wire fabric. The specimens simulated, to full scale, conditions in a bare...
Case Studies of Displacement-Induced Fatigue
The potential for displacement-induced cracking is a result of the co-existence of two conditions: an abrupt change in stiffness and a periodic force opposing it. Case studies of retrofitted...
Applications of an Integrated Traffic Analysis Package
This paper presents an integrated traffic analysis package called AAP (the Arterial Analysis Package). AAP, which was developed by the Federal Highway Administration (FHWA), contains three...
Estimating Future Traffic Volumes at the Intersection Level
This paper uses the experience gained on a number of regional and sub-area studies in the northeast to illustrate how measured and forecast traffic information can be combined to predict...
GTRAF: The Netsim Graphics System
This paper describes the development of an interactive computer graphics (ICG) system, named GTRAF, which will provide users with a new and highly efficient methodology for analyzing results...
Development of Graphics Displays for the Integrated Traffic Data System
This paper describes the development of interactive graphics displays for the Integrated Traffic Data System (ITDS) and provides technical details on the hardware and software considerations...
Real Time Vehicle Systems Monitoring
The system, which has recently been developed, consists of onboard vehicle micro-processor monitoring, data reduction and transmission components, a VHF or satellite communications link,...
NEDS?Network Editing and Display for TRANPLAN
This paper explores some of the current and possible future applications of interactive graphics packages to the tasks of analyzing and planning transportation systems. The source of the...
Running Rucus II on a Microcomputer
Since the preliminary version of the RUCUS II (Run Cutting and Scheduling System) was released by UMTA in 1982, the system has achieved considerable acceptance by transit properties. These...
Distributed Graphical Transit Scheduling System
The Graphical Scheduler is the latest of software products developed by SAGE for the transit industry. It was specifically designed to run on a micro-computer taking advantage of the latest...
Using Microcomputers for Maintenance Management in a Small Transit Agency
The Wisconsin Department of Transportation, (WISDOT) Bureau of Transit asked a small transit agency to join an UMTA funded project that would perform a needs assessment, locate or develop...
Facilities Management and Capital Planning Systems
This paper explores the purpose, role, and structure of these systems, showing how micro-computers can be exploited to improve the quality of decision making in capital planning and related...
Role of Microcompiuters in Highway Weigh-in-Motion Systems
Microcomputer technology makes it possible to digitize the signals, calculate the desired factors, and record and display the information in real time at the weigh-in-motion (WIM) site....
SCT's Experience with Automated Fleet Management
Sonoma County Transit's (SCT) fleet maintenance program covers all aspects of repair and preventive maintenance, with the exception of major body work. This paper describes...
Microcomputer Assisted Bridge Rating
Before microcomputers can be useful to those officials responsible for rating the approximately 576,000 bridges in this country, software systems must be developed to analyze and rate...
Bridges and Transmission Line Structures
This volume on Bridges and Transmission Line Structures contains papers from ten sessions and one plenary session of the 1987 ASCE Structures Congress. Eight sessions cover bridges. A...
Earthquakes Will Not Damage This Bridge
A California pipeline bridge has been retrofitted with isolation bearings that damp earthquake shocks. The bridge over Southern California's Santa Ana River carries the Upper...
Connecticut: A Success Story
The Connecticut Department of Transportation (ConnDOT) had warned the state legislature that its highways and bridges would continue to deteriorate without increased funds for inspection,...
The Wet Look
The collapse of the Schoharie Creek bridge drew attention to underwater inspection. Underwater inspection of bridges gives engineers a better understanding of the condition of the bridges....
The Just-in-Case Factor
Computer analysis allows bridge designers to take a more precise look at the old structural principle of redundancy. No one can define redundancy, but everybody knows what it means. Two...
