چکیده:
Since the adverse effects of each accident is subordinated to its direct severity, in studies of
the traffic safety, has been tried a lot for providing the severity models to identify the
severity factors of the adverse effects of the accidents. In this research, the modeling of the
pedestrian accidents severity has been evaluated by using the dual logistic regression and three
methods. In the number one and two methods, the relationship between the independent
variables and the dependent variables respectively was investigated separately (Enter
method) and integrated in the model (forward stepwise method). In the third method, first
the primary independent variables have been reduced to the fewer variables by using a multi
variables statistical method as the analysis to factors method, the variables and then the new
variables relationship with the dependent variable, was analyzed by using the logistic
regression. The dependent variable in the following models is the pedestrian accidents
severity in two injury and fatal categories.

The impact of the road characteristics on the pedestrian’s accidents Some studies have taken a look at the effects of the road designed characteristics on the severity of the injuries such as road width, intersections place, and presence of the crosswalks repetition, sidewalks and traffic lights that these factors will be evaluated in this part.
Based on their findings, the pedestrians’ volume had had a major and positive relationship with the pedestrian’s accidents in the single prediction model that has included all types of the intersections (12).
Also the number of vehicles entering the intersections in each day, had been a major and positive factor in the pedestrian’s accidents prediction models [9 and 12].
Environmental characteristics influence on the pedestrians accidents Atmospheric condition: the atmospheric condition that has an impact on the road surface and the drivers braking capability for the pedestrians has not been shown as an effective factor in injuries risk, according to a study in 2002 [2].
The area of study and research method The main objective of this research is to find a relationship between the pedestrian’s accidents and the different effective factors on it in within-city roads.
