Calibration of a Bridge Rating Formula for Overload Permits
This paper proposes a method to calibrate a reliability based load and resistance factor design (LRFD) permit evaluation formulation that will account for the overloaded truck's...
Fault Identification by Seismic Impact Load Techniques
The propagation of seismic waves generated by impact loading across a normal fault in carbonate rock was investigated by the seismic refraction technique. The field records were reduced,...
Projectile Penetration Into Reinforced Concrete and Steel Targets
This paper presents brief preliminary results of a research program sponsored by the Air Force Weapons Laboratory (AFWL) to investigate the interaction of 30-mm cannon projectiles with...
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,...
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...
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...
Costs of Truck Related Highway Damage to Alaska
The cost of pavement damage to the State of Alaska for truck traffic continues to be a very controversial topic. There is no simple answer since this cost is dependent upon pavement strength,...
Iceberg Impact Load on a Gravity Based Structure
The mechanics of the eccentric collision of an iceberg against a fixed, rigid, gravity based structure are discussed. A closed form solution is derived for the case of infinite friction...
Soil Strength Recovery Using a Clegg Impact Device
The research described in this paper uses the Clegg Impact Device to determine the relative strength of a soil, and describes how this information can be used to develop the strength recovery...
Analysis of R/C Slab Under Turbine Missile Impact
Turbine missile impact on reinforced concrete barrier in nuclear reactor power plants is simulated using the finite element method. One of four full scale turbine missile impact tests...
Evaluation of Safety Alternatives by Benefit/Cost Analysis
There is an increasing awareness of the need to use limited highway safety funds on projects that offer the greatest benefits. This paper describes the development and application of a...
Performance of Highway Traffic Barriers
This paper describes an investigation of traffic barrier performance in New York State. A one-year sample of all traffic-barrier accidents in the state was obtained from Department of...
Transitioning End Terminal A TRENDtm for the Future
The highway engineer frequently starts from a position where an identified highway element is causing serious injuries or fatalities to motorists on the nation's highways....
Hazardous Events After Redirectional Collisions
The potential for hazardous events occurring to vehicle occupants after a redirection from a longitudinal barrier has not been adequately addressed. Very few studies are available which...
Occupant Risk in Longitudinal Barrier Collisions
The following paper presents data derived from sled test experiments, full-scale vehicle crash tests as well as an in-depth analysis of accident data which suggest that occupants are not...
Design of an Expert System for the Rating of Highway Bridges
A microcomputer-based expert system used to determine the effects of vehicles and overloaded vehicles on simple span bridges with reinforced concrete deck and prestressed concrete I-beams...
Assessment of Safety Impacts of Highway Projects
In this paper the safety impact of highway improvement and maintenance activities is examined in terms of accident reduction potentials of these activities. There are three causes of accident:...
Trends in Containerships and Their Impact on Terminal Design
A revolution in ocean shipping operations, affecting both landside equipment and cargo handling methods, is underway. In today's container shipping industry, maximum efficiency...
