一、研究目的: 随着城市道路的不断发展,三幅路式的路面组成形式逐渐增多。因此,在次干道与三幅路相交路口处(或单位与三幅路相交处)车辆通行、横穿或由次干路进入快车线时的速度,直接影响着在快车线正常行驶车辆速度和安全。 由于经济的持续发展,从争取高效益的目的出发,各种车辆(包括机动车辆和非机动车)都在不同程度的提高自身的行车速
First, the purpose of the study: With the continuous development of urban roads, the three road pavement composition gradually increased. Therefore, the speed at which the vehicles pass, cross or even enter the express lane at the intersection of the arterial road and the three roads (or at the intersection of the unit and the three roads) directly affects the speed at which the expressway runs normally Safety. Owing to the continuous economic development, all kinds of vehicles (including motor vehicles and non-motor vehicles) are going to improve their traveling speed
