Integration of a Traffic Noise Model and AutoCAD
TrafficNoiseCAD represents a new approach to noise analysis and barrier design by integrating file creation for the FHWA STAMINA 2.0 noise prediction program with interactive graphical...
An Expert System for Stop-Controlled Intersection Design
In 1915, the first stop sign was installed in Detroit, Michigan, but until now, there was still no one coordinated body of knowledge which would dictate design and analysis requirements....
Tutorial on Computer-Aided Design
These tutorial sessions are designed to provide a basic introduction to the use of Computer-Aided Design/Drafting (CAD) in transportation engineering, with particular regard to Civil Engineering...
The Use of Linked Spreadsheets as a Transportation Problem Solving Tool
Spreadsheet modeling is a useful tool for business as well as engineering applications. Until the advent of linked spreadsheets this type of modeling was based on the concept of preparing...
A Peak Hour High Capacity Reservation and Person-Based Functional Classification Concept for Urban Mobility Plans and Corridor Growth Management
The management of future growth and mobility in urban corridors and areas has been based in part upon use of the Levels of Service and procedures of the Highway Capacity Manual. Capacity...
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...
Scoping Out Scour
Bridge scour�soil erosion around piers and pilings�threatens tens of thousands of bridges across the U.S. Traditionally, engineers have mapped bridge scour by driving probes into the subbottom...
Banking on a Bridge

Safety Enhancement of Bridges with Seismic Isolation Bearings
This paper summarizes the experimental and analytical studies done at Dept. of Civil Eng., Kyoto Univ., on application of base isolation bearings to highway bridges and the Menshin (base...
Inelastic Behavior and Seismic Design of a Highway Shield Tunnel
Nonlinear behavior of shield tunnels required for seismic design by means of Seismic Deformation Method is presented based on dynamic loading tests. Application of the test results to...
Rocking Behavior and Retrofit of Tall Bridge Piers
In the aftermath of the damage to the San Francisco Oakland Bay bridge, due to the 1989 earthquake, a comprehensive study of the seismic behavior of the bridge was undertaken. This paper...
Assessment and Testing of Column Lap Splices for the Santa Monica Viaduct Retrofit
This paper describes assessment and the full-scale test of a 3 ft. (914 mm) dia. column containing #11 (34.9 mm dia.) reinforcing steel lap-spliced in the critical region. The column modelled...
Seismic Performance and Retrofit of the Golden Gate Bridge
