The opening of Puerto Rico's Teodoro Moscoso Bridge in San Juan early in 1994 will usher in a new era of privately financed toll roads. The first product of the 1989 Private...
Digital Signal Processing Techniques for Active Structural Control
In the past, implementation of active structural control strategies employing PC-based hardware has been problematic due to excessive computational times required for processing the measured...
California Airports: Ground Access Vehicle Trips, Emissions and Emission Reduction Strategies
The following paper discusses the volume of trips and emissions associated with ground access vehicles to an d from California airports, and potential ways to reduce these emissions. this...
Optimal Supply of Parking at Airports
The design capacity of parking facilities at airports is generally estimated in relation to one or more standard decision variable such as enplaning passengers, number of employees, and...
Rehabbing Bridges Under Traffic
Four urban examples demonstrate how an owner's decision to keep it open during rehabilitation construction forces the designers to contend with an extra set of problems. Reanchoring...
A League of Their Own
New baseball stadiums in Cleveland and Arlington, Tex., opening in April 1994, combine the nostalgia of traditional ballparks with state-of-the-art site planning and structural engineering....
Microsurfacing Urban Pavements
A European maintenance technique called microsurfacing can add years to the service life of cracked, ravelled pavements--with minimal interruption to traffic and for less than half the...
SCHEREC: SCHedule RECovery System
Creating a revised plan requires experience and significant time. To lessen the effort involved, a knowledge-based system named SCHEREC (SCHedule RECovery) was developed which suggests...
Development of an Expert System to Identify Hazardous Highway Spots
The paper describes the development of an expert system within a geographic information system to identify high-hazard spots in a highway network. The philosophy guiding expert system...
The Safety Advisor: An Interactive Object-Oriented Program for Assessing the Safeness of Roadway and Roadside Designs
