The invention discloses a double-lane road local road section single-lane alternate traffic signal dynamic timing method. The method comprises the following steps: determining a local road section traffic influence range of an event; collecting traffic flow data, and analyzing traffic flow characteristics; calculating a delay-based small vehicle equivalent quantity, and calculating a large vehicle adverse impact factor; constructing a signal dynamic timing method for alternate passage of road sections affected by double-lane road events; according to the method, a signal timing optimization model based on dynamic traffic flow characteristics is constructed, traffic flow data, including actual passing time, vehicle model proportion, actual arrival traffic volume and the like, of an event influence road section are collected in real time according to a special scene of an alternate passing road section of a double-lane road, and a signal period and a phase timing scheme are dynamically adjusted. The method can quickly adapt to the traffic fluctuation of the alternate passage road section, reduces the vehicle delay under manual command, improves the vehicle passage efficiency, and enhances the flexibility and dynamic adaptability of the signal timing of the alternate passage road section of the double-lane road.
