Predicting Air Quality Near Roadway Intersections Through The Applicat, Brian Kim
Predicting Air Quality Near Roadway Intersections Through The Applicat, Brian Kim
Electronic Theses and Dissertations
With substantial health and economic impacts attached to many highway-related projects, it has become imperative that the models used to assess air quality be as accurate as possible. The United States (US) Environmental Protection Agency (EPA) currently promulgates the use of CAL3QHC to model concentrations of carbon monoxide (CO) near roadway intersections. This model uses steady-state and macroscopic methods to model the physical phenomena (e.g., emission rates, atmospheric dispersion, etc.) occurring at intersections. These methods are not straightforward and unintuitive for the users. Therefore, this project investigated the possibility of developing a model that is theoretically more realistic and flexible …
Evaluation Of The Impacts Of Its Information Strategies On I-4 Corridor, Yueliang Zuo
Evaluation Of The Impacts Of Its Information Strategies On I-4 Corridor, Yueliang Zuo
Electronic Theses and Dissertations
This study evaluated the impacts of ITS information strategies under incident conditions in Interstate 4 (I-4) corridor of Orlando. The analysis was performed using DYNASMART-P software package. The ITS information strategies range from pre-trip information, en-route information, and variable message signs. Simulation covered one hour during the morning peak period. The impacts of ITS information strategies on mobility were evaluated by simulating the performance of various ITS information components (pre-trip information, en-route information, and variable message signs) under incident conditions for the I-4 corridor and comparing the results with the corresponding scenarios in the absence of these components. The traffic …
