| 摘 要： | 从交通流的连续性假设开始将交通流中的每一个参数(包括交通压力)都在流体流中 找到了恰当的比拟.通过理论推导，得出了类似一维可压缩理想流体流动的交通流连续性方 程、欧拉微分方程和动量方程.并从一维定常交通流的分析研究中，得出了交通压力的数学表 达式.从而得出了由连续性方程、欧拉微分方程、交通压力表达式和状态方程构成的一维交通 流动力模型，论证了该模型与车辆跟驰理论是统一的. |
| 关 键 词： | 交通流 交通压力 车辆跟驰 模型 |

| Abstract: | Alaking a continuum hypothesis, comparing all Parameters (including the traffic pressure) in traffic with in fluid exactly and a series theoretical study, it gives continuity Equation, Euler differentiating equation and momentum equation in traffic as in one-dimensional compressible ideal fluid flaw. It presents the functional relation of the pressure from the research in one-dimensional steady traffic. and the kinetic model that includes the continuity Equation, E uler differentiating equation, pressure function and flow function in one-dimensional traffic flow. Last. It proves the congruity between the kinetic model and the car- following theory. |
| Keywords: | traffic flow traffic pressure car-following theory model |
