Intelligent Transportation Systems and NO2 Emissions: Predictive Modeling Approach Using Artificial Neural Networks
Publisher: American Society of Civil Engineers
Abstract: Environmental or air-quality effects of Intelligent Transportation Systems (ITS) are very difficult to measure. Some researchers have attempted to quantify the effects of individual ITS application on emissions; yet, the ...
Minimizing Highway Noise Barrier Intrusion
Publisher: American Society of Civil Engineers
Abstract: Highway noise control has been practiced in the United States for more than 10 years, as a result of direction provided by the Federal Highway Administration. Through 1980, more than 100 million dollars had been spent to ...
Prediction of Highway Construction Noise Levels
Publisher: American Society of Civil Engineers
Abstract: A model for the prediction of noise levels from highway construction operations has been developed under sponsorship of the Federal Highway Administration (FHWA). Noise sources are geometrically represented as points, lines ...
Introduction: Special Section on Expert Systems and Computer‐Aided Planning and Design
Publisher: American Society of Civil Engineers
Use of Vegetation for Abatement of Highway Traffic Noise
Publisher: American Society of Civil Engineers
Abstract: The high cost of conventional highway noise abatement methodology (i.e., free‐standing walls) has made mitigation of many impacted sites economically infeasible. A solution that may prove more economically reasonable for ...
Comparing Traffic-Noise Model Accuracy Using State-Specific Emission Data
Publisher: American Society of Civil Engineers
Abstract: In September 1999, the writers began a study for the Arizona Department of Transportation to develop Arizona-specific Reference Energy Mean Emission Levels. This study was conducted to determine if the noise emission ...
Environmental Planning in Urban Transportation
Publisher: American Society of Civil Engineers
Abstract: Environmental analysis of transportation systems is a comprehensive and demanding task. The environmental planner is required to carefully and objectively examine project data provided by transportation planners and ...
Controlling Sewage Treatment Plant Noise
Publisher: American Society of Civil Engineers
Abstract: Many local agencies responsible for the sewage treatment process manage a large number of small treatment facilities that serve low-density residential areas. This process is often noisy and, as a result, frequently generates ...
Highway Noise and Land Use Compatibility
Publisher: American Society of Civil Engineers
Knowledge Acquisition for Domain Experts
Publisher: American Society of Civil Engineers
Abstract: Of all the stages of expert systems construction, none is more critical than knowledge acquisition. This is particularly true in instances where domain experts such as civil engineers develop expert systems themselves, ...
