自行车车道离机动车道仅有几英尺，机动车规定速度必须保持在每小时30英里，这是在西雅图干道上的速度限制，但实际上许多车辆都是以每小时40英里的速度行驶的。
A few feet from the cycling lane traffic moves at speeds of between 30 miles per hour, the speed limit for arterials in Seattle, and 40 miles per hour, the speed at which many cars actually travel.
该模型可以对实际的事故进行再现分析和车辆碰撞速度估算。
Thus, the simulation model can estimate the vehicle velocity in pedestrian-vehicle accident and can be applied to a real traffic accident reconstruction.
