The invention provides an intelligent network connection mixed traffic flow prediction method and device and electronic equipment, and belongs to the technical field of traffic flow prediction. According to the invention, the speed and position of the man-driven vehicle and the intelligent network connection vehicle at each moment can be predicted through the mixed traffic flow model. For a manually-driven vehicle, an acceleration random item is set in the manually-driven vehicle following model, and the perception error of a driver is represented by normal distribution with the mean value being zero. Furthermore, the variance of the normal distribution of the perception error is changed in real time, is determined based on the speed of the vehicle at the current moment and/or the vehicle following distance, and is in positive correlation. That is, the larger the speed of the vehicle and/or the vehicle following distance is, the larger the variance of the normal distribution of the perception error is, and the larger the represented perception error of the driver is. In this way, the real-time updated manual driving car following model describes the driving behavior, and the actual situation of manual driving perception error change is better met. Based on the real-time updated manual driving car-following model, the predicted mixed traffic flow is more accurate.

    本发明提供一种智能网联混合交通流预测方法、装置及电子设备,属于交通流预测技术领域。本发明能够通过混合交通流模型预测人工驾驶车辆和智能网联车辆各时刻的速度和位置。针对人工驾驶车辆,在人工驾驶跟车模型中设置加速度随机项,并以均值为零的正态分布表征驾驶员的感知误差。进一步的,感知误差正态分布的方差是实时变化的,是基于当前时刻车辆的速度和/或跟车间距确定的,呈正相关。即,车辆的速度和/或跟车间距越大,则感知误差正态分布的方差越大、表征的驾驶员感知误差越大。这样实时更新的人工驾驶跟车模型描述驾驶行为,更加符合人工驾驶感知误差变化的实际情况。基于实时更新的人工驾驶跟车模型,预测的混合交通流更加准确。
