A CADD Program for Simulating Turning Vehicles
The turning capability of one or more 'design' vehicles and their swept paths has a significant influence on the layout of transportation facilities such as roadway intersections, parking...

Development of Bridge Load Model for LRFD Code
The load models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck...

Full-Scale Bridge Test to Monitor Vibrational Signatures
A full-scale highway bridge, in the process of being demolished and replaced was monitored using vibrational techniques in its in-service condition. The bottom flange and web of one fascia...

Vibration and Impact in Skewed Steel Bridges
The vibration and impact of skewed multigirder bridges due to vehicles moving across rough bridge deck are studied. The bridges are modeled as grillage beam systems. The vehicle is simulated...

Remote Monitoring of a Stressed Timber Bridge Deck
The long term behavior of a CCA treated stressed timber deck bridge is being monitored, at present, using a remote data acquisition system. The bridge which is located in Gray, Maine was...

Marginal Overweight Operating Scenario for DOE's Initiative I Highway Casks
This paper assesses the potential transport of high-capacity Initiative I highway casks under development by the Office of Civilian Radioactive Waste Management (OCRWM) as permitted marginal...

Effect of the Periodic Secondary Irregularity on the Dynamic Behaviour of Railway Bridge-Vehicle System
The deformation and vibration of bridge will be developed due to the moving vehicles, especially for railway bridge. The dynamic deflections in the points under each wheel are called secondary...

Dynamic Response of Bridges Under Traffic Loads
Numerous analytical and experimental investigations have been carried out in the past to study the complex dynamic problem of the response of a bridge deck to a moving vehicle. However,...

A Spatial Decision Support System for Vehicle Routing
This paper describes the design, development, and implementation of a computer aided system for planning efficient network maintenance routes. The system has been used to design snow and...

A Dynamic Mapping Application for an ATIS
A dynamic mapping application for an Advanced Traveler Information System (ATIS) is described. The application requires tracking maintenance vehicles so that paths can be displayed indicating...
