中文摘要:

当模特儿的宏和有道路宽度的交通流动的答案被调查。第一,有道路宽度的考虑的一个新宏模型被建议。第二,一致流动和小不安上的道路宽度的效果被学习。分析、数字的结果显示出那拓宽(缩小) 道路能提高(还原剂) 平衡速度和流动,和增长(减少) 将与道路宽度坡度的绝对值增加。另外,数字结果说明新模型能在一致流动和小不安的进化上描述道路宽度的效果。

英文摘要:

The macro modeling and the solution of traffic flow with road width were investigated. Firstly, a new macro model with the consideration of road width was proposed. Secondly, the effects of road width on uniform flow and small perturbation were studied. The analytical and numerical results show that widening (shrinking) road can enhance (reduce) the equilibrium speed and flow, and the increments (decrements) will increase with the absolute value of road width gradient. In addition, the numerical results illustrate that the new model can describe the effects of road width on the evolutions of uniform flow and small perturbation.
