| 摘 要： | 提出一种城市路段机非混合行驶条件下存在摩擦干扰的元胞自动机模型.该模型是在机动车NS模型的基础上引入一条摩擦减速规则,使受到自行车干扰的机动车进行减速.根据模型的规则,对不同机动车密度和非机动车密度的情况进行仿真,仿真结果基本符合实际的情况,得到机动车在干扰情况下通行能力平均下降20%左右,平均速度下降18%左右.最后,通过实际观测数据的验证,表明该模型可靠性较好. |

| Abstract: | The paper proposes cellular automaton (CA) model under the frication interference in mixed traffic condition. The model is built on NS model with a slowdown rule showing that motor vehicles slow down under the frication interference of bicycles. With various motor vehicle densities and bicycle densities, the simulation results of this model are consistent to the real situations. The results show that under the interference of bicycles, the average capacity of motor vehicle has decreased by 20% while its average velocity has decreased by 18%. Moreover, data from real observation and measurement also demonstrate validity and reliability of this model. |
| Keywords: | cellular automaton model mixed traffic frication interference slowdown rule |
