Safety Analyses At Signalized Intersections Considering Spatial, Temporal And Site Correlation
… identify the significant factors contributing to crashes, this dissertation investigated the temporal, spatial, and site correlations for total, rear-end, right-angle and left-turn crashes. Using the basic regression model for correlated crash data leads to invalid statistical inference, due to …

Modeling Crash Frequencies At Signalized Intersections In Central Flor
A high percentage of highway crashes in the United States occur at intersections. These crashes result in property damage, lost productivity, injury, and even death. Identifying intersections associated with high crash rate is very important to minimize future crashes. The purpose of this study is …

Neural Network Trees And Simulation Databases: New Approaches For Signalized Intersection Crash Classification And Prediction
Intersection related crashes form a significant proportion of the crashes occurring on roadways. Many organizations such as the Federal Highway Administration (FHWA) and American Association of State Highway and Transportation Officials (AASHTO) are considering intersection safety improvement as …

Safety Effects Of Traffic Signal Installations On State Road Intersections In Northeast Florida
… to identify those factors which help predict crashes after a signal is installed, and to develop a crash prediction model. It is the intent of this thesis to supplement the Manual on Uniform Traffic Control Devices Signal Warrant procedure and aid the traffic engineer in the signal …

A New Approach To Identify The Expected Crash Patterns Based On Signalized Intersection Size And Analysis Of Vehicle Movements
Analysis of intersection crashes is a significant area in traffic safety research. This study contributes to the area by identifying traffic-geometric characteristics and driver demographics that affect different types of crashes at signalized intersections. A simple methodology to estimate crash …

Analysis Of Type And Severity Of Traffic Crashes At Signalized Intersections Using Tree-based Regression And Ordered Probit Models
… the factors that contribute to traffic crashes at such locations. One approach is to model crash occurrences based on configuration, geometric characteristics and traffic. Instead of combining all variables and crash types to create a single statistical model, this analysis created …
