Analysis of the Contributory Factors to Accidents at Signalized Intersections using Generalized Estimating Equation with Negative Binomial Distribution

A Simple Method for Estimating Generalized Negative Binomial Distribution

A simple and quick method of estimating the parameters of the Generalized Negative Binomial Distribution (GNBD) has been suggested. A Monte Carlo technique has been applied to study the unbiasedness and the efficiency of the estimates so obtained. Using this method of estimation the GNBD has been fitted to some observed data and the fits have been found quite satisfactory.

Pedestrian Accidents with Left-turning Traffic at Signalized Intersections: Characteristics, Human Factors and Unconsidered Issues

Analysis of the Impact of user’s Violations on the Saturation Flow Rate at Signalized Intersections

Accurate estimation of saturation flow rate is a prerequisite for accurate estimation of level of service and delays of signalized intersections. Saturation flow rate of intersections depends on many factors, including traffic behavior and culture. One of the important problems of traffic behavior in Iran is the violation of law at the physical region of intersections. The main purpose of this ...

Estimating Pedestrian Volumes and Crashes at Urban Signalized Intersections

Crash prediction models are used to estimate the number of crashes using a set of explanatory variables. The highway safety community has used modeling techniques to predict vehicle-to-vehicle crashes for decades. Specifically, generalized linear models (GLMs) are commonly used because they can model non-linear count data such as motor vehicle crashes. Regression models such as the Poisson, Zer...

Characteristics of rear-end accidents at signalized intersections using multiple logistic regression model.

Multi-vehicle rear-end accidents constitute a substantial portion of the accidents occurring at signalized intersections. To examine the accident characteristics, this study utilized the 2001 Florida traffic accident data to investigate the accident propensity for different vehicle roles (striking or struck) that are involved in the accidents and identify the significant risk factors related to...
