| 摘要： | The purpose of this project was to identify annual trends and contributory factors of crashes involving mature drivers, vulnerable road users, fatal and injury crashes involving guiderail, and collisions resulting from vehicle failures. Three years of data, covering the years 2014 through 2016, were used in the analysis. Based on data in the present study, mature drivers appear to have issues during wet weather or in wet roadway surface conditions, at night and at intersections. In line with national trends, the majority of pedestrian crashes in Pennsylvania occurred mostly in urban areas, at night, during rainfall events, and at intersections involving careless turns. The majority of bicycle crashes occurred in urban areas, at night, during rainfall events, and when the collision involved a bicyclist or motor vehicle failure to obey a traffic control device. In crashes involving a motorcyclist, speeding- and alcohol-related collisions with fixed objects were prominent, as were collisions on horizontal curves at night. In the present study, crashes involving horse?driven buggies were overrepresented at night and involved careless turning and rear?end collisions. Guiderail crashes were overrepresented on rural roads, horizontal curves, and wet pavement surfaces. Finally, the most common vehicle failure crashes were associated with tire, brake systems, and steering, which is consistent with national statistics. |
