摘要
从提高车流的稳定性和降低车流能耗的角度,考虑多辆车相对速度的总体阻尼效应,提出一种多重"向前看"多速度差交通流跟驰模型(MRVOV模型),并将该模型与几种典型的跟驰模型的稳定性及能耗进行比较。结果表明在充分利用前方车辆运动信息的情况下,MRVOV模型能较好的反映现实交通的跟驰效应,仅仅考虑前方较少车辆对当前车的影响,就可以增强车流的稳定性,降低资源浪费,减少对周围环境的污染。
We take the relation between energy consumption and stability in the several typical traffic models such as the many neighbors interaction models （with multi-weight or multi-velocity difference） and the OV model with relative velocity into account. The energy consumption and stability in different traffic model are calculated and compared. The results show that the more stable traffic flow, theless energy consumption is. An extended multiple ＂look-ahead＂ model is presented considering multiple velocity difference ahead with non-local effect. The effect of velocity difference in car follow has been discussed by improving stability, reducing energy consumption and environment pollution.
