【摘要】：基于抑制交通流不稳定性所需的条件,分析司机后视获得的最相邻后车综合信息对交通流不稳定性的影响.在司机关注前车信息概率大于关注后车信息概率与司机敏感系数大于0的现实条件下,解析分析以及仿真分析得到了以下结论:1)最相邻后车车头距信息减小了交通流的不稳定性,且关注概率越大,减小作用越大;跟驰车与最相邻后车的速度差信息增加了交通流的不稳定性,且关注概率越大,增加作用越大.2)最相邻后车综合信息对交通流的不稳定性的减小作用大于增加作用,即最相邻后车综合信息减小了交通流的不稳定性.3)司机距离差敏感系数越大,最相邻后车综合信息对交通流的不稳定性减小作用越大.4)司机速度差敏感系数越大,最相邻后车综合信息对交通流的不稳定性增加作用越大.
[Abstract]:Based on the conditions needed to restrain the traffic flow instability, the influence of the most adjacent rear vehicle comprehensive information obtained by the driver's back view on the traffic flow instability is analyzed. When the driver pays more attention to the information probability of the front car than the car information after the attention and the sensitivity coefficient of the driver is greater than 0, The following conclusions are obtained by analytical analysis and simulation analysis: (1) the information of the nearest rear vehicle headway reduces the instability of traffic flow, and the greater the probability of attention, the greater the effect of decreasing; The velocity difference information between the following car and the nearest rear car increases the instability of the traffic flow, and the greater the attention probability, the greater the increase. 2) the effect of the comprehensive information of the nearest rear car on the instability of the traffic flow is greater than that of the increase. That is, the more sensitive coefficient of distance difference between drivers, the greater the effect of the most adjacent rear vehicle information on the instability of traffic flow. 4) the greater the sensitivity coefficient of driver's speed difference. The effect of the most adjacent rear vehicle information on the instability of traffic flow is greater.
