The invention relates to a road traffic capacity and networked automatic driving vehicle equivalent coefficient estimation method. The method comprises the steps of obtaining a saturated vehicle headtime interval average value and a layout type; obtaining the number of networked automatic driving vehicles in a research range; obtaining the number of queues formed by the networked automatic driving vehicles; obtaining a mixed saturated traffic flow vehicle head time interval average value in a specific arrangement form; calculating the probability of a specific arrangement form through a probability quality function; obtaining a final mixed saturated traffic flow vehicle head time interval average value; and obtaining the road traffic capacity and the networked automatic driving vehicle equivalent coefficient PCE. Compared with the prior art, calculation is effectively simplified, and meanwhile the defect that a networked automatic driving vehicle formation strategy is generally ignored in current research is overcome.
