This thesis evaluates the safety effects of intersection safety devices (ISD). The purpose of ISD cameras is to reduce the number of collisions that result from red-light running and speeding at intersections. Typically, ISD cameras are placed at one or more approaches of an intersection and...
Visibility is one of the basic requirements for safe driving. Any type of vision obstruction can interfere with the driver’s ability to operate a vehicle and thus poses a significant risk to road traffic safety. In addition to widely investigated adverse weather conditions such as rain, fog, and...
This thesis extends the current research on graph theory-based techniques to meet the needs of planners of multimodal transit networks. Graph theory was originally developed in the 1700s to study transportation systems although it was not adapted to study public transportation networks until the...
This thesis expands previous research on operating speed models by developing models for tangent segments in an urban road environment. The thesis explored the relationships between operating speeds and several road features which have not been previously investigated. Typically, operating speed...
Speeding is the number one road safety problem in many countries around the world. Speeding contributes to as many as one third of all fatal crashes, and is considered an aggravating factor in crash severity. Because of the adverse consequences of speeding, speed management is considered to be...
This thesis evaluated the safety effects of automated mobile enforcement at both the segment-based level and city-wide level over a period of eight years. For the segment-based evaluation, the before-and-after Empirical Bayes (EB) method was used to account for the regression-to-the-mean effect...
