The application discloses a
traffic signal lamp trigger type
countdown control output method, comprising the following steps: S100, configuring
signal lamp
fixed time countdown time length and configuring
current cycle phase information; S200, reading the cycle phase information of the
traffic signal lamp at the
current time node and the
signal lamp
fixed time countdown time length, and generating a running phase chain table; S300, judging whether the time before the non-traffic light color of the current lost traffic right phase meets the configured
fixed time countdown time length; S400, if the configured fixed time countdown time length is met, triggering the corresponding
countdown timer; if the configured fixed time countdown time length is not met, performing countdown correction and calculating the countdown extension time; and S500, repeating steps S200-S400. The application can generate a running phase chain table under the condition that
traffic intersection parameters are pre-configured, pre-add, real-time update and calculate
signal control data to achieve accurate control of the time when the trigger signal triggers the
countdown timer, and realize the trigger type
pulse control countdown
algorithm.
