本文讨论了道路收费对交通流空间分布的影响。推导了具有放射状网络的环形城市的交通流密度。交通流量密度描述了交通流量与位置的函数关系，并使我们能够识别潜在拥堵区域的位置。交通流密度的解析表达式表明了收费区的大小和收费水平对交通流的空间分布的影响。随着收费区规模的增加，收费区内车流的降幅变得更小。随着收费水平的提高，收费区边界的车流量增幅变得更大。研究了出行成本对交通流空间分布的影响。这些结果可以用来确定收费区域的大小和达到一定程度的交通拥堵所需的收费水平。
This paper discusses the effect of road pricing on the spatial distribution of traffic flow. The traffic flow density is derived for a circular city with a radial-arc network. The traffic flow density describes the amount of traffic as a function of position and allows us to identify the location of potential congestion areas. The analytical expression for the traffic flow density demonstrates how the size of the toll area and the toll level affect the spatial distribution of traffic flow. As the size of the toll area increases, the decrease in traffic flow inside the toll area becomes smaller. As the toll level increases, the increase in traffic flow at the boundary of the toll area becomes greater. The effect of the travel cost on the spatial distribution of traffic flow is also examined. These findings can be used to determine the size of the toll area and the toll level required to achieve a certain level of traffic congestion.
