*3.3. Methods of Analysis*

Multiple regression analysis was used to assess the effectiveness of the PPS design types, considering the influences of other factors. Vehicle speed is the strongest influence on traffic safety [59], and accordingly, speed variables were used to assess pedestrian safety. We followed convention and assumed that the faster a vehicle moves, the greater the risk of traffic accidents and other threats to pedestrians. There were two groups of regression models, depending on the dependent variable.
