Optimization Of Path Based Sensor Spacing On A Freeway Segment For Travel Time Prediction During Incidents, Patricia Kathleen Dijoseph
Optimization Of Path Based Sensor Spacing On A Freeway Segment For Travel Time Prediction During Incidents, Patricia Kathleen Dijoseph
Dissertations
Congestion on freeways is increasing and a key source of it is non-recurring incidents. Accurate vehicle travel time predictions are needed during these incidents in order for roadway users to make informed trip decisions. Path based sensors are becoming a leading technology in gathering real-time travel time data. The data is used to make travel time predictions that are then provided through various means, such as dynamic message signs, to roadway users. These types of sensor are located at stationary points along a roadway and collect individual vehicle travel time data from vehicles as they drive pass the sensors.

A Framework For Guiding Transportation Improvements To Support Desired Land Use, Jiruttichut Leoviriyakit
Dissertations
There is a growing recognition that transportation and land use policies cannot succeed independently of one another. The interactions between them must be understood, analyzed, and accounted for in order for land use and transportation plans and policies to be effective and successful. A methodological framework is presented that can help urban planners determine what outcomes can be expected in terms of change in land use patterns within the targeted communities and within the county should a transportation project be undertaken.
The framework is based on an interaction between travel demand model TRANSIMS and land use model TELUM that enables …

Developing Crash Modification Factors For Operational Parameters On Urban Freeways, Eugene Vida Maina
Dissertations
Studies have shown that, roadway safety has become an intensively investigated topic with the objective of improved understanding of the factors that cause crashes to occur. However, it has been shown that as traffic volumes continue to increase across the United States, 52% of drivers feel less safe on the roads today more than they did five years ago and that the American public feels that traffic safety is a serious problem that needs both the government and media to pay more attention to this issue.
In response to these public and driver grievances, State and National transportation agencies have …
