The Development And Evaluation Of A Detection Concept To Extend The Red Clearance By Predicting A Red Light Running Event, Jun Xu May 2009

The Development And Evaluation Of A Detection Concept To Extend The Red Clearance By Predicting A Red Light Running Event, Jun Xu

Masters Theses

This study focuses on developing and evaluating a detection concept to extend the red clearance by predicting a RLR event. It will dynamically extend the red clearance several seconds when a RLR is predicted to happen otherwise zero. Therefore the time will be used more efficient. In order to evaluate the influence caused by alternative detector positions, a VISSIM network was built up, connecting Econolite ASC/3 controller and ATACID. Due to the lack of realistic data, all the data in this study are fictional, but close to real. Several parameters are artificially modified in order to gain larger RLR occurrence. …


Classification Of Subwatershed Slopes And Geotechnical Characterization Of Steep Slopes On Reclaimed Mine Lands In East Tennessee, Patrick Hamilton White May 2009

Classification Of Subwatershed Slopes And Geotechnical Characterization Of Steep Slopes On Reclaimed Mine Lands In East Tennessee, Patrick Hamilton White

Masters Theses

Mining and logging activity in the Appalachian region create both excessive runoff and sedimentation in local streams and rivers. Also, the Surface Mining Control and Reclamation Act of 1977 led to over compaction of mine spoil which has led to reclaimed mine lands which will not grow economically viable native hardwood forests. In recent years a construction technique known as low compaction grading has allowed for suitable tree growth but stability and sedimentation have not yet been explored. The purpose of this paper is to create a rapid assessment method to classify the characteristics of watersheds based upon their geomorphology, …


Identifying Methods To Reduce Conflicts Between Automobiles And Bikes In China Using Microsimulation, Terrance Quashun Hill May 2009

Identifying Methods To Reduce Conflicts Between Automobiles And Bikes In China Using Microsimulation, Terrance Quashun Hill

Masters Theses

With an ever-expanding population and rapid modernization, China is faced with transportation related problems that are both familiar and foreign to the rest of the industrialized world. There is also a large increase in rural-urban migration, resulting in high income disparities and thus diverse transportation needs. While a small but growing percentage of the urban population is adopting automobiles, there are still many people who rely on two-wheel transportation. Engineers in many of the urban cities are facing challenges resulting from an increase in the number of conflicts between various forms of transportation including bicycles, buses, cars, electric bicycles, and …
