Modeling the impacts of weather, spatial and temporal factors on traffic operation

It is well known that weather, spatial and temporal factors significantly influence traffic operation. The purpose of this research is developing a traffic model which contains effects of related factors. Data processing and factor selection are crucial and preliminary work for this modeling. The methodology and process of model development is shown step by step in the following paragraphs. The impacts of factors can be seen directly from conducted traffic model, which can support traffic management and decision-making.
