Application of Machine Learning and Deep Learning Approaches for Traffic Operation and Safety Assessment at Signalized Intersections
The exponential traffic growth hasn't been well-handled by traditional control systems. Adaptive controls are necessary at signalized intersections since they foresee traffic demand based on AI approaches and make decisions ahead of time. These approaches also boost traffic safety by predicting …

Assessment methodology for the environmental impact of bridges
… emissions due to structures (their construction, operation, maintenance, and end of life) can have a real impact on the total emissions of greenhouse gases in the world. Many rating systems have been established to evaluate the performance of buildings and their environmental impact. However, less …
